How to Choose Polyester Sutures for Your Practice
- Braided Construction with Coating — Most dental polyester sutures are coated (polybutilate or silicone) to reduce surface friction during tissue passage and knot tying, while the braided core provides higher tensile strength retention than monofilament nylon.
- Tensile Strength Retention — Polyester retains close to its full tensile strength for the duration it remains in tissue, making it preferred over nylon or silk for periodontal flap anchorage where prolonged wound-edge support is required.
- Knot Security — The braided structure provides strong knot security with fewer throws than monofilament sutures such as polypropylene, reducing operative time during multi-suture flap closures.
- USP Size — 3-0 and 4-0 polyester are standard for periodontal surgery; 5-0 is used for finer anterior aesthetic flap closure.
- Tissue Reactivity and Wicking — As a braided material, polyester carries a higher bacterial wicking risk than monofilament sutures, so meticulous oral hygiene instruction is important during the healing period.
Polyester vs Other Non-Absorbable Sutures
| Suture | Construction | Tensile Strength Retention | Best For |
|---|---|---|---|
| Polyester | Braided, coated | High, sustained | Periodontal flap anchorage |
| Nylon | Monofilament | Moderate, declining | Routine extraction closure |
| Silk | Braided, uncoated | Moderate | General soft tissue approximation |

Frequently Asked Questions
Why is polyester suture preferred over nylon for periodontal flap surgery?
Why is polyester suture preferred over nylon for periodontal flap surgery?
Polyester retains close to its full tensile strength for as long as it remains in tissue, unlike nylon which progressively loses strength, making it more reliable for periodontal flap anchorage where extended wound-edge support is needed during healing.
What does the coating on polyester sutures do?
What does the coating on polyester sutures do?
Most dental polyester sutures are coated with polybutilate or silicone to reduce surface friction, which makes the suture pass through tissue more smoothly and improves knot-tying ease compared with an uncoated braided material.
How does polyester suture knot security compare to monofilament sutures?
How does polyester suture knot security compare to monofilament sutures?
Polyester's braided structure provides strong knot security with fewer throws than monofilament sutures such as polypropylene, which require additional throws to prevent slippage — this reduces operative time during multi-suture flap closures.
What USP size of polyester is used for periodontal flap closure?
What USP size of polyester is used for periodontal flap closure?
3-0 and 4-0 polyester are standard for periodontal flap surgery, while 5-0 is reserved for finer anterior aesthetic flap closures requiring more precise tissue approximation.
