An interventional study of locking and non locking suture techniques and non locking suture technique in Trismus and Swelling, sponsored by Watim Medical & Dental College. Completed at 1 site in Pakistan. Open to participants aged Up to 45 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-09-01.

To compare the two different suture knot techniques, locked and unlocked, in terms of mean on postoperative trismus and swelling after impacted mandibular third molar surgery.
The rationale behind conducting a comparative analysis of two different suture knot techniques on postoperative trismus and swelling following impacted third molar surgery stems from the imperative need to optimize patient outcomes and improve surgical practices. Impacted third molar surgery, while a routine procedure in oral and maxillofacial surgery, often presents challenges in managing postoperative complications, particularly trismus and swelling, which can significantly impact patients' comfort, recovery, and overall satisfaction.

The participating patients will be randomly assigned into two groups, i.e. receiving locked (L) or unlocked (UL) sutures, using a lottery method. Equal patients will be assigned in both groups. In group L (Locked suturing), the flap will be repositioned and sutured with the locked technique (straight-reverse-straight) hermetically using 3-0 black silk. In group UL (Unlocked suturing), the flap will be repositioned and sutured with the unlocked technique (three straight knots) loosely using 3-0 black silk. Demographic details (including name, age, gender, contact) will be obtained and recorded on specific data collection forms. On the day of surgery before the surgery commences, measurements will be taken for trismus and swelling which will be entered on the data collection form. Trismus will be evaluated by measuring the distance between the mesio-incisal corners of the upper and lower right central incisors at maximum mouth opening in mm, using Castroviejo instrument.

Time frame: 3 days and 7 days post operatively
Effect of locking and unlocking sutures on facial swelling
The facial swelling in cm will be determined by measuring the distance from the corner of the mouth to the attachment of the earlobe following the bulge of the cheek and the distance from the outer canthus of the eye to the angle of the mandible using a plastic measuring tape.
Time frame: Post operative day three and day seven
Ran from Jan 2025 to primary completion in Aug 2025, 7 months.
Of 57 non-industry interventional studies with no phase under Trismus, half reached primary completion within 8 months of starting (the median), counting those still running; a quarter within 4 and three quarters within 21. This study's 7 months is below that.
Counting every sponsor, half of 58 studies reached it within 8 months; a quarter within 4 and three quarters within 21.
