摘要/Abstract

摘要： 目的: 分析椅旁CAD/CAM全瓷修复体的类型及使用的全瓷材料的颜色区间,为指导临床椅旁全瓷修复的应用及材料的颜色选择提供参考。方法: 收集整理2021年1月—2021年12月上海交通大学医学院附属第九人民医院口腔修复科使用椅旁CAD/CAM切削IPS e.max CAD材料的修复体相关数据。对修复体的数量、类型和全瓷材料的颜色分布进行调查,分析修复体的类型和材料的颜色分布频率。结果: 共纳入1 374枚修复体,其中,冠修复体最多,624例,占总修复体的45.41%;贴面516例,占37.55%;嵌体219例,占15.94%;固定桥均为粘接桥,数量最少,仅15例,占1.09%。修复材料的选择方面,低透（LT）瓷块的使用频率显著高于其他透明度的瓷块;A色系为使用频率最高的颜色。贴面最常选用的瓷块为LTA2和LTA1;嵌体使用最多的为LTA3;冠使用最多的为LTA2和LTA3;固定桥使用的瓷块均为LT色系,A3色占多数。结论: 使用IPS e.max CAD材料制作的椅旁CAD/CAM全瓷修复体已广泛用于临床,修复体类型包括贴面、嵌体、冠和粘接固定桥。临床最常用的IPS e.max CAD瓷块为LTA2、LTA3、LTA1,这对基层医院的临床修复决策及瓷块储备具有一定的指导意义。

Abstract: PURPOSE: To analyse the types of chairside CAD/CAM all-ceramic restorations and the color range of all-ceramic materials used so as to provide reference for the application of clinical chairside all-ceramic restoration and the color selection of all-ceramic materials. METHODS: IPS e.max CAD prostheses and related data were collected from January 2021 to December 2021 from the Department of Prosthodontics, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine. The number and type of restorations and the color of materials were investigated and analyzed by descriptive statistics. RESULTS: A total of 1 374 restorations were included, of which 624 were crown restorations, accounting for 45.41% of the total restorations. 516 cases were veneer, accounting for 37.55%; 219 were inlays, accounting for 15.94%; fixed bridges were all adhesive bridges, with the least number with only 15 cases, accounting for 1.09%. In terms of the selection of restoration materials, the use rate of low-transparent(LT) ceramic blocks was significantly higher than that of other transparent ceramic blocks. A was the most frequently used ceramic color. The most frequently used porcelain blocks for veneers were LTA2 and LTA1; for inlay were LTA3; for crowns were LTA2 and LTA3. The blocks used in the fixed bridges were all LT, and A3 color was the majority. CONCLUSIONS: Chairside CAD/CAM all-ceramic prostheses made of IPS e.max CAD materials have been widely used in clinical practice. The types of prostheses include veneer, inset, crown and fixed bridge. The most commonly used IPS e.max CAD blocks are LTA2, LTA3 and LTA1. These findings have certain guiding significance for the clinical restoration decision and the reserve of porcelain blocks in primary hospitals.
