面蜡型雕刻技术是制作修复体的基础。因为雕刻技术主要用于金属(牙合)面的蜡型,所以必须在熟练掌握牙体解剖的基础上,结合(牙合)的生理功能,雕刻成形。 一、基本要求:(牙合)面应凸凹分明,牙尖与脊形成(牙合)面的凸部,沟窝形成(牙合)面的凹部。(牙合)面最重要的外形是脊,脊与脊相交即形成(牙合)面的沟和窝,与对(牙合)牙应有多点接触,但接触面要小,咀嚼时形成切割作用,省力,减少(牙合)面的磨损。
Face wax sculpture is the basis for the production of prosthesis. Because the carving technique is mainly used for the metal (occlusal) face wax type, it must be based on the master dental anatomy, combined with (occlusion) physiological function, sculpture forming. First, the basic requirements: (occlusal) surface should be convex and concave, the cusp and ridge form (occlusal) convex surface, the groove to form (occlusal) surface of the concave. (Occlusal) surface is the most important shape is ridge, ridge and ridge intersection that form (occlusal) surface of the groove and nest, and the (occlusal) teeth should have more contact, but the contact surface is smaller, formed when chewing Cutting effect, effort, reduce (occlusal) surface wear.
