烤瓷用于固定修复已有90多年的历史,因其硬度高、耐磨损,近似天然牙色,化学性稳定,无毒,不刺激组织,热传导低等优点,一直视为较好的固定修复材料之一。但因有脆性大,在重咬合力下易裂的缺点,近20多年来采用了烤瓷熔附金属的固定修复,即用合金先制成修复体的底层,再于其上熔附烤瓷。此种修复体强度高,能承受较大(牙合)力,又合乎美观要求。但修复体成功的要点之一是烤瓷与合金的结合(简称瓷
Porcelain for fixed repair has been 90 years of history, because of its high hardness, wear resistance, similar to the natural tooth color, chemical stability, non-toxic, does not stimulate the organization, the advantages of low heat conduction, has been regarded as a better fixed One of the repair materials. However, due to the brittleness, under the bite of the shortcomings of easy bite force, the past 20 years, the use of ceramic fixed metal melt repair, that is made of alloy first prosthesis bottom, and then fused with porcelain . Such a restoration of high strength, can withstand greater (occlusal) force, but also in line with aesthetic requirements. However, one of the main points of restoration success is the combination of porcelain and alloy (referred to porcelain
