Nonresorbable versus resorbable sutures in oral implant surgery: a prospective clinical study.
BACKGROUND
Regarding the Brånemark implant system, nonresorbable sutures have been advocated for reapproximation of the flaps. Fast-absorbable sutures are frequently used in oral surgery, which is convenient for both the patient and the surgeon. It would be advantageous if fast-absorbable sutures are suitable in implant surgery as well.


OBJECTIVE
The purpose of this study was to compare irradiated polyglactin 910 (Vicryl Rapide, Ethicon GmbH, Norderstedt, Germany) suture with a nonresorbable polyfilament suture (Supramid, Schwarz, Resorba GmbH, Nürnberg, Germany) used in oral implant surgery.


METHODS
The study comprised 101 edentulous patients (52 females, 49 males) who were provided with 350 Brånemark implants. They were randomized to receive either Vicryl Rapide suture (n = 61) or 3-0 Supramid suture (n = 40). The patients were evaluated after 10 days and at the time of abutment surgery. Any wound complications and implant losses were recorded.


RESULTS
The implant failure rate at abutment surgery was low (1.2%), and no difference was seen between the two suture groups. A higher incidence of complications (mainly wound dehiscence) was found in the absorbable suture group, especially when a continuous suture was used.


CONCLUSIONS
The results of this study indicate that it is possible to use irradiated polyglactin 910 sutures in oral implant surgery without affecting the rate of early implant failure. However, it is recommended to add interrupted "security sutures" if a continuous suture technique is used in combination with fast-absorption suture material.
