Abstract

Abstract: Objective: To analyze the influence of different bone types on the accuracy of digital implant guide. Methods: According to the set inclusion and exclusion criteria, a total of 62 patients were included, the implant surgery assisted by digital guide plate was performed for all patients. The implant position after different bone implant surgery was matched with the preoperative design position. Results: The patients were aged from 34 to 74 years old, with an average of (49.6±9.69) years old. The shoulder offset of 62 implants was (1.38±0.26) mm, the apical offset was (1.57±0.24) mm, the angle offset was (1.75±0.62)°, and the apical offset was slightly larger than shoulder offset. The shoulder deviation of grade I bone was greater than that of grade Ⅱ, Ⅲ, and Ⅳ bone (P<0.05). The apical deviation of grade Ⅰ and Ⅳ bone was greater than that of grade Ⅱ and Ⅲ bone (P<0.05). The angle deviation of grade Ⅰ bone was greater than that of grade Ⅱ, Ⅲ, and Ⅳ bone (P<0.05). Conclusion: The accuracy of dental digital implant guide is affected by different bone types. Grade Ⅱ and Ⅲ bone are the best bone for digital implant guide.

Key words: digital implant guide, accuracy, shoulder, apical, angle
