摘要：
Functional and esthetic results require accurate implant placement. We aimed to develop a predictive method for assessing dental implant accuracy, and to evaluate the cumulative system influence of surgical guides. A mathematical model was constructed to determine the influence of surface changes on a specific point, using Jacobian matrix expressions. Tooth-supported guides with a specific locating surface were designed for model verification. Ten guides were fabricated for in vitro virtual implant accuracy tests. Locating surface errors of 0.15 mm caused significant deviations in implant positioning. Tooth-supported guide location errors significantly impacted implant accuracy, emphasizing the need for precise guide placement.
