3D打印全程导板在口腔种植外科手术中的应用分析

Abstract

Abstract: Objective: To analyze the accuracy of 3D printed whole course guide plate assisted oral implant surgery, and evaluate its role in oral implantation. Methods: Forty-one cases involving 60 teeth of dental implant were selected. They were implanted between March 2021 and March 2022 in the dental implant department, and they were divided into two groups: Three dimensional printing whole guide plate planting group and free hand planting group. Each group involved 30 teeth. CBCT were taken preoperatively in all cases, and routine oral scans were carried out by using “Dentiq Guide software”. Implant operations were performed in the guide plate group, but routine implant surgery in the position designed by the software. CBCT were overlapped before and after operation by using “Dentiq Guide software”. The design implant position was measured before operation and the actual implant position was measured after operation. The location difference was calculated between the two groups, and the accuracy of 3D printed plate was compared with that of free hand implant surgery. Results: There were significant differences in the buccolingual angulation, implant neck, and apical mesiodistal error between the two groups (P<0.01). The error of the guide plate planting group was smaller than that of the free hand planting group; In terms of postoperative pain, the guide plate planting group was also significantly lighter than that of the free hand planting group(P<0.01); There are differences in the mesiodistal angulation error and postoperative swelling between the two groups (P<0.05); there were no statistically significant differences in the implant placement depth and the buccolingual error at the implant neck and root (P>0.05). Conclusions: The application of 3D printed guide plates in implant surgery is superior to the free hand planting of experienced planting doctors in terms of surgical accuracy and post response, and it can achieve precise planting oriented by restoration.
