摘要
全瓷修复材料包括玻璃基质陶瓷、玻璃渗透氧化物陶瓷、致密氧化铝陶瓷和氧化锆陶瓷4类,全瓷修复方法包括全冠、贴面、瓷粘接修复等。不同的材料和方法搭配,获得的治疗效果差异明显。确定最适宜的搭配形式,可以明显降低临床选择治疗方案的难度。对于活髓牙修复,最佳治疗方案是采用玻璃基质陶瓷材料,进行瓷贴面或瓷粘接修复;死髓前牙一般不采用玻璃基质陶瓷全冠修复,大部分可采用的治疗方案是氧化锆陶瓷全冠修复,如果基牙变色严重可选择玻璃渗透氧化物陶瓷全冠修复;死髓后牙修复常规采用氧化锆陶瓷材料全冠修复,通过增加轴沟或钉洞辅助固位设计提高固位力,通过采用高颈环设计或者全锆冠设计提高修复体的强度。
All-ceramic materials include glass-ceramics,glass-infiltrated ceramics,pure alumina core system and zirconia core system;and all-ceramic restoration methods include crown,veneer and ceramic-bonding restorations.Different match of materials and methods will lead to different treatment result.The most suitable match can help dentists lower the risk.For most vital teeth,the most suitable design is veneers or bonded-ceramic restorations;but for unvital anterior teeth,glass-ceramic is not suitable,and in most cases zirconia crown is the best choice,or in serious strained teeth glass-infiltrated ceramic could be used;in vital posterior teeth,zirconia crown is the most suitable treatment plan,whose retention force can be increased by assistant retention form like axis grooves or pin hole,and strength can be enhanced by high cervical rings or full-zirconia design.
