Abstract:
Objective To evaluate the effectiveness of computer aided design (CAD) and three bit printing in the management of orthognathic surgery.Methods A total of 5 cases of patients with jaw deformity were involved in this study;jaw teeth and CT scanning laser scanning hefore surgery,virtual surgery design of 3D reconstruction and fusion data were analyzed,according to the design scheme of double jaw surgery combined with genioplasty;design and 3D printing of maxillary Le Fort Ⅰ osteotomy,genioplasty titanium alloy resin osteotomy and positioning guide,sagittal split ramus osteotomy by 3D printing and plate technology were used in this approach.The postoperative results were compared with the surgical planning by three-dimensional measurement and statistical analysis.Results When the operation guide plate was applied smoothly,the maximum error for maxilla was 1.2 mm (0.3-1.2 mm),and the maximum error for genioplasty was 1.7 mm,(0.5-1.7 mm),and the mean error was less than 1 mm.Follow-up for 12 months showed no adverse reaction.Conclusions Three dimensional printing surgical guide plate can accurately provide the osteotomy information,effectively control the jaw movement,and improve the orthognathic surgery accuracy of patients with partial jaw deformity.
