Abstract

We studied the postsurgical stability of the mandible using biodegradable Poly-L-lactide bone mini plate fixation undergone sagittal split ramus osteotomy. The forty patients with mandibular prognathism without facial asymmetry (17 males and 23 females) operated from March 2003 to March 2009, were divided into two groups based on the types of osteosynthesis used. 22 patients (9 males and 13 females) using the PLLA mini-plate (PLLA plate group), and 18 patients (8 males and 10 females) using the titanium mini-plate (titanium plate group) were examined. Lateral cephalograms were taken immediately before the surgery, one month, and one year after surgery. Changes in position of the mandible were examined. As a result of this study, remarkable relapses were not recognized at one year after operation for males and females in both groups. It is thought the PLLA mini-plate fixation to the mandible without facial asymmetry setback doesn't present as many problems from the viewpoint of postsurgical stability compared with the titanium mini-plate fixation, and it is profitable that we avoided the plate removal operation. We can select the PLLA or the titanium mini-plate from a comprehensive standpoint.
