Sutures & Needles

Dental Sutures and Needles

After an extraction, a flap or an implant, the closure is the last thing you do and the first thing the patient judges.

Two choices decide it: the suture — does it need to come out? — and the needle — will it pass the tissue cleanly?

Absorbable or non-absorbable?

This is the first decision, and it is about the follow-up visit as much as the wound.

• Absorbable — the body breaks it down, so there is no removal appointment. Best where a review is impractical: children, deep flaps, and the back of the mouth.
• Non-absorbable (silk) — stays until you take it out, usually at 7–10 days. Handles and knots beautifully, which is why it remains the routine choice for a simple extraction with a planned review.

Absorbable sutures

Modern absorbable sutures are braided polyglactin 910, and they resorb over roughly 8–10 weeks while holding strength for the first two.

The useful upgrade is an antibacterial coating. A suture sits half in and half out of the wound, so it wicks bacteria straight to the healing site. A triclosan coating suppresses colonisation of the suture line — worth choosing for third molars, implants and any medically compromised patient.

• The Ethicon Vicryl Plus 3-0 is the antibacterial polyglactin standard, in the everyday intra-oral size.
• The Meril Mitsu AB 2-0 is a triclosan-coated polyglactin at a lower price point.
• For a high-tension flap that needs a heavier thread, the Vicryl Plus #1 steps up the size.

Non-absorbable silk

Braided black silk is still the reference for handling and knot security, and it comes off cleanly at review. It is the sensible default for a routine socket or a frenectomy where you will see the patient again. Silk reels and pre-mounted silk are stocked in the range.

Which suture size?

Size runs backwards — the more zeros, the finer the thread.

• 3-0 and 4-0 — most intra-oral closure. The everyday sizes.
• 5-0 — delicate, aesthetic mucogingival work where the knot must be invisible.
• 1-0 and 2-0 — high-tension flaps that would otherwise pull through.

Cutting or taper needle?

The needle is matched to the tissue, not the suture.

• Cutting — a triangular tip that slices through tough, keratinised tissue: attached gingiva and palate. The Crown half-circle cutting needle and the Sabre cutting needle both suit gingival and palatal closure.
• Taper — a round body that spreads tissue rather than cutting it, for delicate alveolar mucosa and graft membranes, where a cutting edge would tear.

Why buy sutures and needles from Dentalkart

A suture is a sterile, single-use implant that stays in a wound for days. What matters is that the pouch is intact, in date, and genuine — a fogged or torn peel-pouch is a discard, not a gamble.

Every pack here ships sterile with its lot number and expiry legible, and the rest of the surgical tray sits alongside in oral surgery.

What is the difference between absorbable and non-absorbable sutures?

The difference is removal. Absorbable sutures, such as polyglactin 910 (Vicryl), are broken down by the body over roughly 8–10 weeks, so no removal visit is needed — ideal for children and deep or posterior sites. Non-absorbable silk sutures stay intact and are removed at 7–10 days, which suits routine closure with a planned review.

What suture size should I use for a routine extraction?

Use 3-0 or 4-0 for most extraction closure. These give enough tensile strength for a socket without a bulky knot. Reserve 5-0 for delicate aesthetic mucogingival work where the knot must stay invisible, and 1-0 or 2-0 for high-tension surgical flaps that a finer thread would pull through.

When should I use a cutting needle instead of a taper needle?

Match the needle to the tissue. Use a cutting needle, with its triangular tip, for tough keratinised tissue such as attached gingiva and palate — it slices cleanly without tearing. Use a taper needle, with a round body, for delicate alveolar mucosa and graft membranes, where a cutting edge would cut through friable tissue.

What does the antibacterial coating on a suture do?

A suture bridges the wound margin, so it can wick bacteria from the mouth into the healing site. An antibacterial coating, usually triclosan, suppresses bacterial colonisation of the suture itself for the first several days. It is worth choosing in third-molar surgery, implant placement and medically compromised patients, where surgical-site infection risk is higher.

How do I know a suture pack is safe to use?

Check the sterile pouch before opening. It must be intact, sealed and within its printed expiry, with the lot number legible. Do not use a pack with a torn seal, a fogged or peeled pouch, or any sign of moisture — the sterility is compromised, and a contaminated suture placed in a surgical wound is a direct infection route.
