The accuracy analysis of fully-guided mucosa-supported template based computer-assisted implant surgery
摘要
Abstract
Objective The purpose of this study is to determine the accuracy of implant placement in the edentu-lous jaw using computer planning and fully-guided mucosa-supported surgical template by Simplant software. Meth-ods 63 implants were placed in 9 patients (11 fully edentulous jaws), 26 implants were placed in upper edentulous jaw and 37 implants in lower edentulous jaw. Preoperatively, first, a cone beam CT was required for patients with radio-graphic template and radiographic template respectively. Therefore, the data of CBCT was inputted in Simplant software by DICOM format, followed by virtual implant planning. Hereafter, a mucosa-supported surgical template was designed by dentist and made by Masterilise company to allow implant placement using the template as a guide. To investigate the accuracy of implant placement, a postoperative CBCT scan was obtained and matched to the preoperative scan. Theaccuracy of implant placement was validated three-dimensionally including divations of implant shoulder, apical point, axial angulation and depth. Results The survival rate of 63 implamts for a 6 month to 10 year observation period was 100%. The mean divation of implant shoulder was 0.73 ± 0.53 mm, implant apical point was 1.15 ± 0.62 mm, implant depth was 0.95 ± 0.64 mm and implant axial angulationwas 4.10 ° ± 3.23°. Conclusion Divation between virtual and actual implant was existed and it should be considered preoperatively when virtual implant was planned to avoid injur-ing anatomic structure and keeping surgery safely. Correct manipulation during implant operation are helpful to de-crease the divation of implant placement.关键词
