Get a clear overview of the types of absorbable sutures, their uses, and how to choose the right suture for dental and oral surgery procedures.
Every dental procedure presents a unique challenge, and your choice of suture should be tailored to meet it. For wounds that heal quickly, a rapidly dissolving suture is ideal. For complex surgeries requiring long-term support, you need a material that maintains its strength for weeks. This is where a deep understanding of absorbable sutures becomes a clinical advantage. Knowing the distinct properties of the various types of absorbable sutures—from their tensile strength and absorption rates to their handling characteristics—allows you to confidently select the perfect material for every situation. This guide provides a comprehensive overview to help you master your selection process and ensure predictable, successful outcomes for your patients.
Key Takeaways
-
Prioritize predictable healing by opting for synthetic sutures: Materials like Polyglycolic Acid (PGA) are absorbed through hydrolysis, which causes minimal tissue reaction and provides a more controlled absorption timeline compared to the enzymatic breakdown of natural gut sutures.
-
Align the suture’s lifespan with the tissue’s healing needs: Use short-term absorbable sutures for fast-healing extraction sites, and select long-term options to provide extended support for slower-healing tissues involved in bone grafting or implant procedures.
-
Recognize when non-absorbable sutures are the superior choice: For wounds under high tension or those requiring guaranteed long-term stability, the consistent tensile strength of a non-absorbable suture provides the control and security that absorbable materials cannot.

What Are Absorbable Sutures and How Do They Work?
Absorbable sutures are advanced wound closure materials designed to be broken down and absorbed by the body over time. Unlike non-absorbable sutures that require a follow-up appointment for removal, these stitches dissolve naturally. This makes them an excellent choice for closing internal tissues or for patients where a return visit is inconvenient. This biological process eliminates the need for manual removal, streamlining the healing phase for both the clinician and the patient.
The primary function of an absorbable suture is to provide temporary but reliable tissue approximation, holding wound edges together until the tissue has healed enough to withstand normal stress on its own. The rate of absorption is predictable and varies depending on the material, allowing you to select a suture that matches the healing timeline of the specific tissue—from rapidly healing mucosal tissue to slower-healing deeper layers. This precision is critical for ensuring optimal outcomes in procedures ranging from simple extractions to complex periodontal surgeries. For dental professionals seeking dependable performance, the MacSuture line offers a range of sterile absorbable sutures designed for optimal handling, knot security, and biocompatibility in various oral surgery applications.
How the Body Absorbs Suture Material
The body breaks down absorbable suture materials through two main biological processes: enzymatic degradation and hydrolysis. Natural sutures, such as surgical gut, are typically broken down by enzymatic reactions where the body’s enzymes digest the foreign material. This process can sometimes provoke a more significant inflammatory response as the body works to break down the protein-based material.
In contrast, most modern synthetic absorbable sutures, like those made from Polyglycolic Acid (PGA), are absorbed through hydrolysis. In this process, water molecules in the body penetrate the suture filaments and slowly break them down into smaller, absorbable components. Hydrolysis is generally a more predictable and less inflammatory process, providing consistent tensile strength loss and absorption rates. This controlled degradation is a key reason why synthetic absorbable suture materials are widely used in modern dentistry.
Key Advantages of Self-Dissolving Sutures
Using absorbable sutures offers significant advantages that contribute to better clinical outcomes and an improved patient experience. One of the most immediate benefits is the elimination of a suture removal appointment, which saves valuable chair time and reduces patient anxiety. This is particularly beneficial in pediatric dentistry or for patients with mobility challenges.
From a clinical standpoint, these sutures promote excellent wound healing by providing secure closure that minimizes the risk of infection and supports proper tissue alignment. As the suture dissolves, it reduces the potential for long-term tissue irritation or suture-related complications. This leads to enhanced healing, less patient discomfort, and more predictable postoperative results, making absorbable sutures a cornerstone of effective wound closure in countless dental procedures.
What Are the Main Types of Absorbable Sutures?
When selecting an absorbable suture, the first major decision is choosing between natural and synthetic materials. Each category offers distinct properties that influence handling, tissue reaction, and absorption profile. The right choice depends entirely on the specific clinical situation, including the type of tissue you're working with, the tension on the wound, and the required healing time. Understanding the fundamental differences between these two groups is the first step toward ensuring predictable and successful wound closure for your patients.
Both natural and synthetic sutures are designed to be broken down by the body, eliminating the need for a follow-up removal appointment. However, the way they achieve this differs significantly. Natural sutures are typically broken down by the body’s enzymes, while synthetic sutures dissolve through hydrolysis, a process where water molecules break down the polymer chains. This difference in absorption mechanism directly impacts their performance, strength, and biocompatibility, making one type more suitable than the other for certain oral surgery procedures.
A Look at Natural Sutures
Natural absorbable sutures are derived from purified animal tissues, most commonly the collagen from bovine or ovine intestines. The classic example is surgical gut, often called "catgut." These sutures are broken down through enzymatic degradation, a process that can sometimes provoke a more significant inflammatory response in the surrounding tissue. Because the rate of absorption can vary depending on the patient and the presence of enzymes, their performance can be less predictable than synthetic alternatives. They are typically used in tissues that heal quickly and don't require long-term wound support. While historically significant, many clinicians now prefer synthetic options due to their improved predictability and lower reactivity.
An Overview of Synthetic Sutures
Synthetic absorbable sutures are crafted from man-made polymers and are the go-to choice for most modern dental procedures. These materials, such as Polyglycolic Acid (PGA) and Polyglactin 910, are broken down through hydrolysis, a gentle process that minimizes tissue inflammation and ensures a highly predictable absorption rate. This reliability gives you greater control over the healing timeline. Synthetic sutures also tend to retain their tensile strength for a more consistent period before absorption begins. Our MacSuture collection includes sterile PGA sutures, which offer excellent handling, secure knotting, and predictable performance for reliable wound closure and optimal patient healing.
Comparing Natural and Synthetic Suture Materials
Choosing the right suture involves weighing the benefits of natural versus synthetic materials. Natural sutures, derived from biological sources, are broken down by the body’s enzymatic processes. This can sometimes lead to a more pronounced inflammatory response. Synthetic sutures, on the other hand, are absorbed through hydrolysis, a more predictable process that typically causes less tissue reaction. This difference in absorption mechanism is a key factor in clinical decision-making, as it directly impacts healing time, wound security, and patient comfort.
The decision ultimately comes down to the specific clinical scenario, including the required healing time, tissue type, and desired handling characteristics. While natural sutures have a long history of use, modern synthetic materials offer greater consistency and are engineered for specific performance outcomes. Understanding the properties of each type allows you to select the ideal material to support optimal healing for every procedure. Let's break down some of the most common absorbable materials used in dental and oral surgery.
Understanding Plain Gut and Chromic Gut
Plain gut and chromic gut are natural absorbable sutures derived from the purified collagen of sheep or cattle intestines. Plain gut is absorbed relatively quickly by enzymatic degradation, typically within 7 to 10 days, making it suitable for mucosal tissues that heal fast. Chromic gut is treated with chromium salts, which cross-links the collagen fibers to slow down the absorption process to around 10 to 21 days. This provides extended wound support for tissues that require more time to heal. While historically important, many clinicians now prefer synthetic options from collections like MacSuture for their predictable absorption rates and lower potential for tissue reaction.
Exploring Polyglycolic Acid (PGA)
Polyglycolic Acid (PGA) is a synthetic, braided suture that offers excellent tensile strength and predictable absorption. Unlike natural gut sutures that are broken down by enzymes, PGA is absorbed through hydrolysis, a process where water molecules break down the polymer chains. This leads to a more controlled and less inflammatory healing environment. PGA sutures typically maintain their strength for several weeks and are fully absorbed within 90 days. Their reliable performance and good handling make them a versatile choice for a wide range of dental procedures, from extractions to soft tissue repairs, ensuring dependable wound closure.
Key Features of Polyglactin 910 (Vicryl)
Polyglactin 910, commonly known by the brand name Vicryl, is another popular synthetic, braided suture. It is absorbed by hydrolysis and is known for its smooth handling and excellent knot security. This material retains approximately 50% of its tensile strength at two to three weeks post-implantation and is completely absorbed within 60 to 90 days. A key advantage of Polyglactin 910 is its minimal tissue reactivity, which helps support a smooth and uncomplicated healing process. These features make it a go-to choice for many types of oral surgery where reliable, mid-term wound support is essential.
The Role of Poliglecaprone 25 (Monocryl)
Poliglecaprone 25, or Monocryl, is a synthetic monofilament suture designed for soft tissue approximation where short-term wound support is needed. As a monofilament, it passes through tissue with minimal drag and reduces the risk of bacterial wicking. It is absorbed via hydrolysis, losing most of its tensile strength within 7 to 14 days and being fully absorbed in 90 to 120 days. Its pliable feel and excellent handling characteristics make it an ideal choice for closing mucosal layers and other delicate tissues that heal quickly, ensuring patient comfort without compromising wound security.
When to Use Polydioxanone (PDS)
When a procedure demands long-term wound support, Polydioxanone (PDS) is an excellent option. This synthetic monofilament suture provides extended tensile strength, retaining significant integrity for up to six weeks. Its absorption, which occurs through slow hydrolysis, is completed over approximately 180 days. This prolonged support is crucial for slow-healing tissues or in procedures like guided bone regeneration, certain implant placements, or complex soft tissue grafting where maintaining tissue position is critical for a successful outcome. PDS is a vital tool in a clinician’s arsenal of dental equipment and supplies.
How Long Do Absorbable Sutures Last?
The absorption profile of a suture is one of the most critical factors in selecting the right material for a procedure. The duration a suture maintains its tensile strength and remains in the tissue directly impacts wound healing and patient outcomes. Absorbable sutures are broken down into three main categories based on how long they last, ensuring you can match the material to the tissue’s specific healing needs. At SurgiMac, our MacSuture collection includes options across these timelines to support every type of oral surgery. Understanding these timeframes helps you provide secure wound closure for the precise amount of time your patient needs.
Short-Term Absorption (Up to 2 Weeks)
Short-term absorbable sutures are designed for wounds that heal quickly and require minimal support. These sutures typically lose the majority of their tensile strength within 7 to 14 days. They are ideal for superficial soft tissue closure, such as closing small incisions or securing skin grafts where the underlying tissues mend rapidly. Materials like Plain Gut fall into this category. Because they dissolve so quickly, they eliminate the need for a follow-up removal appointment, which is a great benefit for both the clinician and the patient. Choosing a rapidly absorbing suture prevents unnecessary foreign material from lingering in the body once the wound has gained enough strength to close on its own.
Mid-Term Absorption (2–8 Weeks)
For many dental procedures, mid-term absorption provides the perfect balance of support and dissolution. These sutures maintain their strength for several weeks, supporting the wound through the most critical phase of healing before gradually being absorbed. Materials like Polyglycolic Acid (PGA) and Polyglactin 910 are common choices here. For example, Polyglactin 910 typically loses about 50% of its strength in the first week but can take months to disappear completely. This makes them excellent for wisdom tooth extractions, periodontal flap surgery, and other procedures where tissues need reliable approximation for more than just a few days. These dissolvable dental stitches are true workhorses in daily practice.
Long-Term Absorption (Up to 6+ Months)
When you’re working with slow-healing tissues or need extended wound support, long-term absorbable sutures are the answer. These materials are engineered to retain their strength for six weeks or more, with complete absorption taking up to six months or longer. Polydioxanone (PDS) is a prime example of a long-term absorbable suture. It’s an ideal choice for dental implant procedures, bone grafting, and major maxillofacial surgeries where the tissues require prolonged stabilization to heal properly. Using a long-lasting suture in these cases helps reduce the risk of infection and wound dehiscence, ensuring a more predictable and successful outcome for complex cases.
How to Choose the Right Absorbable Suture
Selecting the right absorbable suture is a critical decision that directly influences wound healing, patient comfort, and the overall success of a dental procedure. It’s not about finding a single "best" suture, but rather about matching the material's properties to the specific clinical situation. The ideal choice provides adequate support during the critical healing phase and then dissolves predictably, eliminating the need for a follow-up removal appointment. This decision requires a careful evaluation of several interconnected factors: how the material interacts with the body's tissues, how strong it needs to be, how quickly it should be absorbed, and the unique health profile of your patient.
By thoughtfully considering these elements, you can ensure the wound closure is secure, inflammation is minimized, and the healing environment is optimized. A well-chosen suture supports the body’s natural recovery process, leading to better clinical outcomes and a more positive patient experience. For every procedure, from a simple extraction to complex periodontal surgery, the suture is a fundamental tool that helps bridge the gap between the surgical intervention and a complete, healthy recovery. Making an informed choice is the first step toward achieving that goal.
Evaluate Tissue Reaction and Biocompatibility
The ideal suture should cause minimal tissue reaction to allow for clean, uncomplicated healing. Biocompatibility refers to how well a material coexists with living tissue without causing an adverse immune response. Natural sutures, like plain or chromic gut, tend to provoke a more significant inflammatory response as the body breaks them down enzymatically. In contrast, synthetic polymers are absorbed through hydrolysis, a gentler process that typically results in less tissue reaction. The choice depends on the procedure and patient; a minimal reaction is almost always preferred to reduce inflammation, discomfort, and the risk of infection.
Match Tensile Strength to the Procedure
Tensile strength is the amount of force a suture can withstand before it breaks. The suture you choose must be strong enough to hold the wound edges together securely against the natural tensions of the surrounding tissue, especially in mobile areas like the cheeks or tongue. The key is to find the perfect balance of strength, flexibility, and longevity for the specific surgical site. For example, a high-tension area may require a suture with a longer-lasting tensile strength profile, while a simple soft tissue closure may not. Our MacSuture line offers reliable options to meet various procedural demands.
Consider the Required Absorption Rate
The absorption rate of a suture must align with the healing rate of the tissue it’s supporting. The suture should maintain adequate tensile strength throughout the critical wound healing period and then dissolve. If it absorbs too quickly, the wound may dehisce. If it remains too long, it can act as a foreign body, potentially causing irritation or becoming a nidus for infection. For tissues that heal quickly, a rapidly absorbing suture like Polyglycolic Acid (PGA) is suitable. For slower-healing tissues, such as in guided bone regeneration, a long-lasting suture like Polydioxanone (PDS) is a better choice.
Account for Patient-Specific Factors
Every patient is different, and their individual health status can significantly impact wound healing and suture choice. Factors such as age, nutritional status, immune function, and conditions like diabetes can delay recovery. For patients with compromised healing or poor oral hygiene, using a synthetic monofilament suture can help reduce the risk of bacterial wicking. Absorbable sutures are particularly beneficial for these patients, as they enhance comfort and eliminate the need for a removal appointment, which also supports better infection control and reduces chair time. A personalized approach ensures the best possible outcome for each individual.
Matching Sutures to Common Dental Procedures
Choosing the right suture is a critical decision that directly impacts wound healing, patient comfort, and the overall success of a procedure. There’s no single suture that fits every clinical scenario; the ideal choice depends on the tissue type, the tension on the wound, the expected healing timeline, and specific patient factors. For instance, a suture that works perfectly for a simple extraction might not provide adequate support for a complex periodontal flap. Understanding how different absorbable sutures perform in various applications allows you to tailor your approach for optimal outcomes.
Matching the suture’s properties—like tensile strength and absorption rate—to the demands of the procedure is key. A rapidly healing site, such as a wisdom tooth socket, benefits from a suture that dissolves quickly, while a site requiring extended support, like a bone graft, needs a suture that maintains its strength for several weeks. Below, we’ll walk through some of the most common dental procedures and discuss which absorbable sutures are typically the best fit for the job, helping you select the right materials with confidence.
Sutures for Wisdom Tooth Extractions
For routine procedures like most wisdom tooth extractions, absorbable sutures are often the go-to choice. The gum tissue in these areas tends to heal relatively quickly, making a second appointment just for suture removal an unnecessary step for both you and your patient. Using a self-dissolving suture streamlines the postoperative process and enhances patient convenience. A fast-absorbing material, such as plain gut or a rapid Polyglycolic Acid (PGA) suture, provides sufficient wound approximation for the initial healing period before dissolving away. The MacSuture line includes reliable absorbable options perfect for these common cases.
Sutures for Periodontal Surgery and Gum Grafting
Periodontal and grafting procedures require a more nuanced approach. These delicate surgeries often involve repositioning tissue flaps or securing grafts where precise and stable closure is essential for success. The choice of suture depends on factors like the location of the wound, the required duration of support, and the expected healing time. A mid-term absorbable suture like Polyglycolic Acid (PGA) is often an excellent choice here. It offers predictable strength for several weeks, securing the tissue during the critical phase of revascularization and integration before it begins to break down, minimizing tissue irritation during the later stages of healing.
Sutures for Dental Implant Placement
Dental implant surgery often involves a two-stage process where wound closure must be secure to protect the underlying site. While a clinician might choose a non-absorbable suture to secure a gum graft or close an incision over a large implant, absorbable sutures are frequently used for primary closure over the implant site. A longer-lasting absorbable suture, such as Polydioxanone (PDS), can be ideal. It provides durable support for four to six weeks, ensuring the tissue remains closed and stable while osseointegration begins. This extended support helps prevent dehiscence and protects the implant from the oral environment without requiring a removal appointment.
Sutures for General Oral Surgery
In general oral surgery, patient-specific factors can heavily influence suture selection. Absorbable sutures are particularly beneficial for patients who may have difficulty returning for a follow-up visit, such as those with transportation challenges or compromised immune systems. Using a suture that dissolves on its own reduces the risk of infection that can be associated with suture wicking and eliminates a potential barrier to care. This makes them a practical and safe choice for a wide range of patients, ensuring wound closure is maintained without adding logistical burdens. This approach aligns with a broader strategy of infection control to promote smooth and uncomplicated healing.
Weighing the Pros and Cons of Absorbable Sutures
Choosing the right suture material is a critical decision that directly impacts healing outcomes and patient satisfaction. Absorbable sutures offer significant advantages in many dental procedures, but they also come with limitations that make them unsuitable for certain clinical situations. Understanding this balance helps you select the best option for every case, ensuring optimal wound closure and recovery. This section breaks down the key benefits and potential drawbacks to guide your decision-making process.
The Pros: Improving Patient Comfort and Healing
The primary advantage of absorbable sutures is the improved patient experience. Since the material dissolves on its own, there’s no need for a follow-up removal appointment, which saves chair time and adds convenience for your patients. This feature is particularly beneficial for individuals with limited access to follow-up care or those with dental anxiety. Biologically, these sutures are designed to break down while minimizing tissue reaction as the wound heals. High-quality MacSuture products are engineered for biocompatibility, reducing the risk of inflammation and supporting a smooth recovery, especially for patients with compromised immune systems.
The Cons: Understanding Potential Limitations
Despite their benefits, absorbable sutures are not a one-size-fits-all solution. Their main limitation is a variable absorption rate, which can be influenced by patient-specific factors like metabolism, oral pH, infection, and overall health. This unpredictability means they may dissolve faster or slower than anticipated. Additionally, the tensile strength of absorbable sutures naturally decreases as the material degrades. This makes them unsuitable for procedures that require prolonged tissue support or are under significant tension. For wounds in high-mobility areas or those needing extended healing time, an absorbable suture might not provide the durable closure required for optimal outcomes.
When to Choose a Non-Absorbable Suture Instead
Non-absorbable sutures are the material of choice when predictable, long-term wound support is non-negotiable. Their stable tensile strength ensures wound edges remain securely approximated for as long as needed, which is critical in complex surgical cases. You should opt for a non-absorbable material for procedures like extensive gum grafts, securing membranes in guided bone regeneration, or closing incisions over large dental implants. In these scenarios, using a non-absorbable option like MacSuture’s Silk sutures gives you complete control over the duration of support, as you determine the precise moment of removal based on clinical evaluation of the healing site.

Frequently Asked Questions
How does the body actually break down synthetic versus natural sutures?
The body uses two different methods. Natural sutures, like surgical gut, are broken down by your body's enzymes, which is essentially a digestive process that can sometimes cause more inflammation. Synthetic sutures, such as the Polyglycolic Acid (PGA) found in our MacSuture line, are broken down by hydrolysis. This means water molecules slowly and gently break the suture material apart, which is a more predictable process and typically results in less tissue reaction.
What patient factors might affect how quickly a suture dissolves?
A patient's individual health plays a big role. Factors like a high fever, infection at the surgical site, or poor nutritional status can speed up the absorption process, especially for natural gut sutures. Even the pH of the oral environment can have an impact. For patients with compromised healing, choosing a reliable synthetic suture can provide a more predictable timeline for wound support.
Can a patient have an allergic reaction to an absorbable suture?
While rare, allergic reactions can occur. Natural sutures derived from animal collagen, like surgical gut, carry a slightly higher risk of causing an inflammatory or allergic response. Synthetic sutures are generally considered more biocompatible and are less likely to cause a reaction, making them a safer choice for patients with known sensitivities or a history of allergies.
What should I tell patients if their absorbable suture falls out earlier than expected?
It's important to reassure them that this can happen and isn't always a cause for alarm. Advise them to contact your office immediately so you can assess the situation. In many cases, if the wound has already closed sufficiently, no further action is needed. However, if the site appears open or there are signs of infection, you'll need to evaluate it clinically to determine if any intervention is necessary.
Are there any major differences in handling synthetic braided sutures compared to natural ones?
Yes, there are a few things to keep in mind. Synthetic braided sutures, like PGA, often have excellent knot security and are very strong. However, they can sometimes have more “memory” than natural sutures. It's important to use proper knot-tying techniques to ensure the knot is seated securely. They also tend to have a smoother passage through tissue, which can be an advantage during placement.
