Application of Three-dimensional Printing Digital Guide Plate Combined with Intraoral Scanning in Denture Restoration
Objective To investigate the effect of three-dimensional printing digital guide plate combined with oral scanning in the application of denture.Methods Eighty-four patients with edentulous were selected from the Department of Prosthodontics of the author's hospital from January 2018 to January 2020,and were divided into two groups by random number table,42 cases in each group.The control group was treated with traditional complete denture restoration method,and the observation group was treated with three-dimensional printing digital guide plate combined with oral scanning technology.The implant shoulder,root,angle,depth deviation and peri-implant marginal bone resorption of the two groups were compared after denture restoration.The implant success rate of the two groups was evaluated at 12 months after denture restoration,and the satisfaction of denture restoration was compared by Oral Health Impact Scale(OHIP-4).Results The success rate of the observation group was 95.93%,which was higher than that of the control group(89.22%)(P＜0.05).Shoulder deviation,root deviation,angle deviation and depth deviation of the observation group were less than those of the control group(P＜0.05).The peri-implant marginal bone resorption of the observation group was(0.24±0.09)mm,which was lower than that of the control group(0.37±0.12)mm(P＜0.05).The scores of masticatory function,fixation function and comfort degree in the observation group were higher than those in the control group(P＜0.05).Conclusion The application of three-dimensional printing digital guide plate combined with intraoral scanning in patients with edentulous denture restoration can improve the success rate of implant,reduce the degree of bone resorption around the implant and the degree of implant position deviation,and improve the satisfaction of patients with denture restoration.The application effect is ideal.
