Abstract:
Objective To compare the operative precision between pioneer drilling guiding and full navigation guiding plates in the flapless immediate implantation. Methods Data of 50 immediate implants, which were implanted from 47 outpatients (50 implants) of Tianjin Stomatological Hospital from 2014 to 2016 were retrospectively analyzed. The patients were conducted on the pioneer drilling guiding system (22 implants) and full navigation guiding sytem (28 implants). The cone beam CT (CBCT) was preliminarily taken and modeled for each patient. All of the patients underwent implant surgery after making guiding plates by three-dimensional reconstruction, simulation planting design and the application of digital rapid prototyping technology. Cavity preparations were made by pioneer drilling and full navigation assisted with planting drills respectively to finish implantation. The post-operative CBCT was taken and performed the three-dimensional reconstruction. The implantation precision guiding by two systems were compared. Results All of the 50 immediate implants were successfully completed with the guiding plates. Implant mucositis appeared in one case after 3 months of temporary repair, and after the targeted therapy, the final repair was finished. The rest cases were finally completed. No implant was loose or fell off. The deviation was less in neck apex and root apex angle in full navigation group than that of pioneer drilling guiding group (P<0.01). But there was no significant difference in axial angle between the two groups after navigation and implantation (P>0.05). Conclusion The digital surgical guiding plates provide nice technical support for the application of the flapless immediate implantation. And the full navigation system has higher precision than that of the pioneer drilling navigation system.
