Abstract:

BACKGROUND: Collagen suture is made of collagen from animals, and has been widely used because it is absorbable, non-rejection and easy to produce, and convenient in use.
OBJECTIVE: To evaluate the effects of collagen suture and silk suture in wound healing after oral implant surgery.
METHODS: 100 patients undergoing oral implantation were randomly assigned into collagen suture group and silk suture group. A 2-0 circular needle with absorbable collagen sutures and a 4-0 circular needle with non-absorbable silk sutures were employed for tension-free suture in the two groups. After 3, 5, 7 days of oral implantation, suture threads and wound healing were observed. The suture was removed at 14 days, and patients were reviewed at 14 days. 
RESULTS AND CONCLUSION: The wound healing was better in the collagen suture group than the silk suture group at grade I (P < 0.05). At 7 days postoperatively, the suture thread was mostly absorbed in the collagen group but not in the silk suture group. In addition, material alba was invisible in the collagen suture group but clear in the silk suture group. These results indicate that the collagen suture is more proper for tension-free suture than the silk suture, which is better matched to the healing time and keeps a better oral environment.
