How to Choose Nylon Sutures for Your Practice
- Monofilament Construction — Nylon's single-strand structure has no interstices for bacteria to wick along, giving it a lower infection risk than braided silk for routine extraction socket closure.
- Memory and Handling — Nylon has more coil memory than polypropylene, requiring an additional throw on the surgeon's knot to prevent loosening, but handles more predictably than highly elastic monofilaments.
- USP Size — 3-0 nylon suits standard extraction socket closure; 4-0 or 5-0 is preferred for finer mucogingival and anterior aesthetic closures.
- Tissue Reactivity — Nylon causes minimal tissue reaction compared with silk, making it suitable for patients with a history of delayed healing or suture-site inflammation.
- Removal Timing — Intraoral nylon sutures are typically removed 7–10 days post-operatively; tensile strength declines progressively after that point as the monofilament begins to degrade.
Nylon vs Other Non-Absorbable Sutures
| Suture | Construction | Tissue Reaction | Knot Security |
|---|---|---|---|
| Nylon | Monofilament | Low | Moderate (needs extra throw) |
| Silk | Braided | Moderate | High |
| Polypropylene | Monofilament | Very low | Low (high memory) |

Frequently Asked Questions
Why is nylon suture preferred over silk for routine extraction closure?
Why is nylon suture preferred over silk for routine extraction closure?
Nylon's monofilament surface has no braided interstices for bacteria to wick along, giving it a lower wound infection risk than braided silk. Silk remains popular for its handling and knot security, but nylon is the better default for routine extraction socket closure where infection risk is a priority.
How many throws are needed to secure a nylon suture knot?
How many throws are needed to secure a nylon suture knot?
Nylon has more coil memory than polypropylene, so an additional throw beyond a standard surgeon's knot (typically four throws total) is recommended to prevent the knot from loosening as the monofilament tries to spring back to its original shape.
When should nylon sutures be removed after a dental extraction?
When should nylon sutures be removed after a dental extraction?
Intraoral nylon sutures are typically removed 7–10 days after extraction. Leaving them beyond this window is not advised, as tensile strength and the smooth monofilament surface progressively degrade, increasing the risk of suture breakage during removal.
Can nylon sutures be used in patients prone to suture-site infection?
Can nylon sutures be used in patients prone to suture-site infection?
Yes — nylon's monofilament structure carries a lower bacterial wicking risk than braided sutures such as silk, making it a reasonable choice for patients with a history of delayed healing or suture-site inflammation.
Does MedSTA supply nylon sutures across Egypt?
Does MedSTA supply nylon sutures across Egypt?
Yes — MedSTA supplies nylon sutures in 3-0, 4-0, and 5-0 USP sizes in EGP, with nationwide delivery across Egypt.
