The biologically oriented preparation technique (BOPT) uses a vertical tooth preparation and simultaneously a controlled rotary instrumentation of the gingival sulcus. The resulting blood clot is stabilized with the interim restoration. However, accurate transfer of the emergence profile of the interim crown to the definitive restoration is essential to maintain the gingival architecture. This technique article describes clinical and laboratory procedures to predictably transfer the emergence profile of the interim crown to duplicate the gingival architecture in the definitive restoration.
生物导向型制备技术（BOPT）采用垂直牙体预备，并同时对龈沟进行控制旋转器械处理。用临时修复体稳定所形成的血凝块。然而，准确地将临时冠的边缘形态转移到最终修复体对于维持牙龈形态至关重要。本文技术介绍了临床和实验室程序，以可预测地将临时冠的边缘形态转移到最终修复体，以复制牙龈形态。
