A method of manufacturing an all-ceramic crown composed of a coping of dense-sintered, high-purity alumina with dental porcelain is described. This method takes the sintering shrinkage of alumina into consideration and makes it possible to produce individual dental copings in dense-sintered, high-purity alumina, which is a biocompatible implant material. The alumina used has density, grain size, and flexural strength within the limits of the values required in ISO 6474-1981, 'Implants for surgery, ceramic materials based on alumina'.
描述了一种制造全瓷冠的方法，该全瓷冠由致密烧结的高纯度氧化铝基底冠和牙科瓷组成。该方法考虑了氧化铝的烧结收缩，并使得能够生产由致密烧结的高纯度氧化铝制成的个性化牙科基底冠，高纯度氧化铝是一种生物相容性植入材料。所使用的氧化铝的密度、晶粒尺寸和抗弯强度在ISO 6474-1981《外科植入物 基于氧化铝的陶瓷材料》所要求的值的范围内。
