Description

一种定制式固定义齿烤瓷贴面
技术领域
本发明属于牙科烤瓷修复领域，尤其是涉及一种定制式固定义齿烤瓷贴面。
背景技术
当今社会，随着生活水平的提高，人们对物质的追求逐步得到了满足，越来越多的是精神层面的追求。精神追求最直接体现在对美的渴求上，尤其是最近几年，人们对美的定位不仅仅局限于面容、身材方面，对牙齿的美白、健康更为重视，拥有一口整齐、洁白、漂亮的牙齿是现代人十大健康标志之一。也正是因此，牙齿美容也正兴起于口腔行业。长期以来，牙体变色，尤其是中、重度四环素牙、氟斑牙，等种种牙齿问题是困扰各行各业人士的一大难题。
贴面又称牙贴面，是采用粘结技术，对牙齿表面缺损、着色牙、变色牙和畸形牙等，在保存活髓、少磨牙或不磨牙的情况下，用修复材料直接或间接粘结覆盖，以恢复牙体正常形态和改善其色泽的一种修复方法，现有铸瓷贴面、氧化锆贴面等备牙量较多，对牙体损伤程度高于烤瓷贴面；而且对着色牙、变色牙体无法完全遮盖，影响美学修复效果。
