Although removable partial dentures are a favored option for the restoration of many situations that involve partial tooth loss, some patients are not satisfied with a removable partial denture, especially when it is not stable during mastication. A dental surveyor can be used to prevent countless problems related to the production of removable partial dentures. Many professionals working with oral rehabilitation fail to take advantage of the many uses of a surveyor in planning and designing chromium alloy and other metal removable partial denture frameworks.
This article uses an academic approach to describe the criteria used to determine the path and removal of a removable partial denture. A fundamental requirement for understanding the correct use of the dental surveyor is to prevent indiscriminate use of a path of insertion perpendicular to the occlusal plane, and extreme inclinations of the cast in the attempt to create undercuts on some teeth.
尽管可摘局部义齿是修复多种部分牙齿缺失情况的首选方案，但一些患者对可摘局部义齿不满意，尤其是在咀嚼时不稳定的情况下。牙用测绘仪可用于预防与可摘局部义齿制作相关的无数问题。许多从事口腔修复的专业人员在规划和设计铬合金及其他金属可摘局部义齿支架时未能充分利用测绘仪的多种用途。
本文采用学术方法描述用于确定可摘局部义齿就位道和脱位道的标准。理解正确使用牙用测绘仪的一项基本要求是避免无差别地使用垂直于咬合平面的就位道，以及为在某些牙齿上形成倒凹而过度倾斜模型。
