What are PGA sutures?
PGA (Polyglycolic Acid) sutures are synthetic, braided, absorbable sutures designed for long-term wound support. They resorb through hydrolysis over 60–90 days and retain tensile strength for up to 2–3 weeks, making them ideal for soft tissue closure in dental and surgical procedures.
When are PGA sutures used?
-
Guided Bone Regeneration (GBR): Helps stabilize membranes over bone grafts during regeneration.
-
Guided Tissue Regeneration (GTR): Supports soft tissue healing while protecting underlying grafts.
-
Socket Preservation: Maintains flap position after tooth extraction and graft placement.
-
Dental Implant Placement: Secures surgical flaps during implant healing.
-
Wisdom Tooth Extractions: Closes surgical sites to promote healing and reduce complications.
How long does it take for PGA sutures to absorb?
PGA sutures retain strength for about 14–21 days and fully absorb within 60–90 days. This reliable absorption profile ensures support through early healing without requiring removal.
What are the advantages of PGA sutures?
-
Easy handling and secure knot retention
-
Predictable resorption timeline
-
Minimal tissue reaction
-
Lower bacterial accumulation compared to natural gut sutures
Are PGA and Vicryl the same?
No. PGA sutures and Vicryl® are similar because both are synthetic, absorbable, braided sutures used for soft tissue closure, but they are not exactly the same material. PGA sutures are made from polyglycolic acid, while Vicryl® is polyglactin 910.
The practical takeaway is simple: both are used when clinicians want absorbable wound support, but product selection should be based on material preference, handling, absorption profile, needle type, and the procedure.
Recommended Vitality™ Suture Options
Choose PGA Antibacterial when longer absorbable tensile support is preferred. Use Chromic Gut when short-term absorbable support is enough for the procedure.
PGA Antibacterial Suture
Synthetic absorbable PGA option for cases where longer tensile support may be preferred.
- Absorbable synthetic suture option
- Longer support than chromic gut
- Useful for oral and periodontal soft tissue closure
3-0 Chromic Gut
Absorbable chromic gut option for short-term oral surgery wound support.
- Alternative when shorter support is preferred
- Good for common oral surgery closure
- Slightly stronger thread size than 4-0
4-0 Chromic Gut — 13mm Needle
Finer absorbable chromic gut option with a 13mm reverse cutting needle.
- Useful for smaller access areas
- Good when a finer 4-0 thread is preferred
- Shorter 13mm needle option
4-0 Chromic Gut — 19mm Needle
Absorbable 4-0 chromic gut option with a 19mm needle for broader oral surgery use.
- Useful for general oral surgery closure
- Longer 19mm needle option
- Short-term absorbable wound support
PGA vs Chromic Gut: Simple Selection Guide
| Suture type | Best fit | Main reason |
|---|---|---|
| PGA Antibacterial | Longer absorbable support | Synthetic absorbable option when longer tensile support is preferred. |
| 3-0 Chromic Gut | Common oral surgery closure | Short-term absorbable support with a slightly larger thread size. |
| 4-0 Chromic Gut 13mm | Smaller access areas | Finer thread with shorter 13mm needle. |
| 4-0 Chromic Gut 19mm | Broader general closure | Finer 4-0 thread with longer 19mm needle. |
