金瓷冠作为一种成功的牙科修复体已有30多年的历史,是一种最常见的人造冠。然而,上遮色瓷过程中,在烧结技术、金属表面的最佳状态等方面尚存在问题。本实验分别使用单层遮色和双层遮色两种技术,通过研究一种瓷(Vita VMK 68)与三种烤瓷合金——金铂钯合金(Jelenko“O”),无银金钯合金(Olympia),镍铬合金(Bexillium Ⅲ)的金瓷结合强度,①比较两种遮
Gold porcelain crown as a successful dental restoration has more than 30 years of history, is one of the most common artificial crown. However, there is still a problem in the process of shading porcelain in terms of sintering technique and the optimum state of the metal surface. In this experiment, we used two kinds of techniques: single-layer opaque coating and double-layer opaque coating respectively. Through the study of a porcelain (Vita VMK 68) and three kinds of porcelain alloys, Jelenko “O” (Olympia), nickel-chromium alloy (Bexillium Ⅲ) gold and porcelain bonding strength, ① compare two kinds of cover
