Abstract

Interdisciplinary treatment planning is an essential part of orthodontic therapy for patients with partial edentulism, especially when dental implants are to serve initially as anchorage and ultimately as prosthetic abutments for the definitive fixed restoration. A technique is presented for designing and fabricating a computed tomography-based surgical guide to place definitive implants before orthodontic therapy. First, the diagnostic cast and the orthodontic tooth arrangement and diagnostic waxing cast are scanned with a 3-dimensional optical scanner. Three-dimensional renderings of these scans are then merged and superimposed onto the cone beam computed tomography (CBCT) image with implant planning software to develop definitive implant positions. A custom surgical guide is fabricated from these data.

摘要

对于部分牙列缺失患者，多学科治疗计划是正畸治疗的重要组成部分，尤其是当牙种植体最初用作支抗并最终用作确定性固定修复的修复基台时。本文介绍了一种在正畸治疗前设计和制作基于计算机断层扫描的手术导板以植入确定性种植体的技术。首先，用三维光学扫描仪扫描诊断模型、正畸牙齿排列和诊断性蜡型。然后，使用种植体规划软件将这些扫描的三维渲染图合并并叠加到锥形束计算机断层扫描（CBCT）图像上，以确定种植体的最终位置。根据这些数据制作定制的手术导板。
