Description
This paper verified the stability of poly-L-Lactic/polyglycolic acid bone fixation devices in Le Fort I osteotomy. The subjects of the study were 40 patients (33 females and 7 males) who underwent Le Fort I osteotomy with fixation by poly-L-Lactic/polyglycolic acid bone fixation devices (plates and screws). The subjects were divided into two groups according to their skeletal deformity pattern: skeletal Class II and Class III. Lateral cephalometric radiographs were measured and compared for the absolute magnitude of skeletal relapse from pretreatment to immediately postoperative to 6 months and 1 year after surgery. The X-axis applied the Sella-Nasion line, and the Y-axis passed through Sella perpendicular to the X-axis. The evaluation factors were A-point, Prosthion, and posterior nasal spine (PNS). In both groups, statistical analysis showed no significant differences in postoperative skeletal stability. In conclusion, poly-L-Lactic/polyglycolic acid bone fixation devices can provide postoperative stability for Le Fort I osteotomy.
