A clear shoulder platform that can be easily identified by doctors and technicians or machines (mouth scan and warehouse scan) is important to obtaining a good long-term and stable fixed prosthesis treatment effect. At present, the pre-paration of the shoulder platform is usually based on free hands, and the practical operation is mainly guided by experience. Moreover, no comprehensive and objective preoperative design, intraoperative verification, and final test are available. Thus, the accuracy of shoulder platform preparation needs to be improved. In this study, the clinical pathway of "three determination, three selection, and three steps" with high accuracy of preparation and the precise shoulder preparation method of "bur-tip guidance" are proposed in detail.
一个清晰的肩部平台，能够被医生、技术人员或机器（口扫和仓扫）轻松识别，对于获得良好的长期稳定固定修复治疗效果很重要。目前，肩部平台的制备通常基于徒手操作，实际操作主要靠经验指导。而且，没有全面客观的术前设计、术中验证和最终检测。因此，肩部平台制备的准确性有待提高。在本研究中，详细提出了制备精度高的“三定、三选、三步”临床路径以及“钻尖引导”的精准肩部制备方法。
