One of the main problems in fixing non-removable orthopedic structures (crowns and bridges) is a violation of the odontopreparation technique. For a strong and reliable fixation of non-removable orthopedic structures, special requirements must be imposed on them in terms of the shape and surface of the support of the processed tooth. These requirements include: parallelism of the walls of the prepared tooth (must be cylindrical); parallelism of the vertical walls of several prepared teeth included in the bridge; smooth continuous gingival ledge [1, 2]. The parallel vertical walls of the prepared teeth provide the most reliable fixation of the prosthetic structure. The parallel walls of adjacent teeth ensure a secure anchoring of bridges. A smooth continuous gingival ridge of the correct shape ensures the tightness of the crown and excludes the penetration of infection between the crown and the tooth. When these three conditions are met in practice, you can be sure that this orthopedic design has the same route of introduction. Based on the analysis of literature data, it should be concluded that the development of odontopreparation methods in order to form the optimal supragingival part of the tooth for further prosthetics is an urgent problem. The development and clinical implementation of dental navigation technologies contribute to the development of methods for monitoring odontopreparations in orthopedic dentistry. The purpose of this article was to analyze the existing methods of odontopreparation and identify the most effective ones among them.
