Abstract:
Objective:To discuss the efficacy of computer aided design (CAD) and computer aided manufacturing (CAM) in the treatment of microgenia by osseous genioplasty.
Methods:From July 2015 to January 2018, 17 cases (Male, n=5, Female, n=12), aged from 17 to 32 years, with the meanage of 24 years, were enrolled. All patients had microgenia, and underwent osseous genioplasty. Computed tomography (CT) was performed preoperatively and 7-10 days postoperatively for all cases. Based on preoperative CT data, CAD was applied to make individualized surgical plan, surgery simulation, todetermine the movement of mentum. CAM was used to prefabricate the individualized surgical templates and transfer the CAD into intraoperative guidance. The registration of CAD and postoperative CT were performed to evaluate the surgical accuracy.
Results:All patients were satisfied with the surgical outcomes. The deformity of microgenia was significantly corrected. The Pg error was (0.24±0.08) mm, and the Me error was (0.15±0.17) mm.
Conclusions:The application of CAD increases the accuracy of surgical planning, and CAM provides areliable guidance with individualized template. Anoptimal surgical outcome can be achieved.
