Abstract

Abstract: Objective: To investigate the clinical application of digital complete overdenture based on intraoral scanner and implant template. Methods: A total of 64 patients from Jan 2017 to Dec 2019 were randomly divided into the control group and experimental group. The control group was treated with conventional complete d enture, while the experimental group was treated with digital complete overdenture based on intraoral scanner and implant template. The implant success rate, peri-implant marginal bone loss, implant position deviation, and denture satisfaction were compared between two groups. Results: The implant success rate in the experimental group was significantly higher than that in the control group, and peri-implant marginal bone loss was lower than that in t he control group (P<0.05). The apex deviation, neck deviation, angular deviation, and depth deviation in the observation group were all lower than those in the control group (P<0.05). The patients' satisfaction with masticatory function, fixed function, and comfort degree was higher than that of the control group (P<0.05). Conclusion: The application of digital complete overdenture based on intraoral scanner and implant template can improve the implant success rate, reduce the peri-implant marginal bone loss and implant position deviation, and improve the satisfaction of denture.
