Role of flap tension in primary wound closure of mucoperiosteal flaps: a prospective cohort study

Clin Oral Implants Res. 2010 Jan;21(1):50-4. doi: 10.1111/j.1600-0501.2009.01829.x.

Abstract

Aim: To evaluate the role of suture tension in primary wound closure of mucoperiosteal flaps.

Materials and methods: Sixty patients, scheduled for a single implant installation, were recruited. Before suturing, the wound closing forces were measured with an electronic tension device. One week after the surgery, the wounds were inspected with regard to complete closure.

Results: The applied tension varied between 0.01 and 0.4 N. In 72% a tension of 0.01-0.1 N was applied, resulting in few dehiscences (10%). Higher closing forces (>0.1 N) increased the percentage of wound dehiscences significantly (> or = 40%).

Conclusions: It appears necessary to control flap tension at the time of wound closure to achieve a primary closure.
