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 preparation 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.

Key words: tooth preparation, tooth shoulder platform, clinical pathway, precise restoration, esthetic dentistry
