• In this study, we evaluated the usefulness of bioabsorbable poly-L-lactide (PLLA) mini-plates for bone fixation after Le Fort I osteotomy and bilateral sagittal split osteotomy (SSRO). The subjects were 19 patients, who received two-jaw surgery using titanium and PLLA mini-plates. Lateral cephalograms were taken before surgery (T1), immediately after surgery (T2), and more than six months after surgery (T3). Changes in the measurement points were statistically analyzed. There was no statistical difference in the postoperative skeletal difference between the two groups. The post-operative stability of PLLA mini-plates is comparable to that of titanium mini-plates. PLLA mini-plates are considered to be clinically useful.
