Stability after Surgery for Jaw Deformity Using Bioabsorbable Osteosynthesis System

Abstract

The study examined the stability of a bioabsorbable osteosynthesis system after surgical correction of jaw deformity. Nine patients received sagittal splitting ramus osteotomy (SSRO), fixed with a bioabsorbable poly-L-lactide (PLLA) osteosynthesis system. Of these, three received simultaneous Le Fort I osteotomy. A control group, of eleven patients, received SSRO. Of these, six received simultaneous Le Fort I osteotomy, fixed titanium plates, and screws. Stability after surgery was analyzed cephalometrically. There was no significant difference in postoperative stability between the two groups, not only in cases of SSRO alone but also in cases of SSRO with Le Fort I osteotomy. These results indicate that the PLLA osteosynthesis system can be used effectively in surgery for jaw deformity.
