Method and system for evaluating implanting precision of an implant

Abstract

Embodiments of the present application provides a method and a system for evaluating implanting precision of an implant. The method includes: obtaining a second surface model of an oral cavity containing a target implant; obtaining an actual position of the target implant in a first three-dimensional model based on the second surface model, the first three-dimensional model and a first surface model; and obtaining an evaluation result of the implanting precision of the target implant based on the actual position of the target implant in the first three-dimensional model and an predicted position of the target implant in the first three-dimensional model. By means of the method and system according to the embodiments of the present application, the second surface model of the oral cavity containing the target implant is obtained after implantation is completed using an oral digital scanning device to obtain the evaluation result of the implanting precision of an implant of the target implant. More accurate evaluation result of implant can be obtained due to the elimination of metallic implant artifacts in the obtained secondary surface model as compared to the three-dimensional digital model obtained based on CT device in the prior art.
