The purpose of this study was to evaluate the clinical outcome of feldspathic ceramic laminate veneers over a 7-year period using minimally invasive techniques, such as vertical preparation (without prosthetic finish line), or no preparation (no-prep). A total of 170 feldspathic ceramic veneers were cemented in the anterior region, including 70 maxillary and 100 mandibular veneers, after special conditioning of the teeth and restorations. The veneers were evaluated using the FDI World Dental Federation criteria evaluation kit after recalling all the patients between February and June 2021. In total, 14 feldspathic veneers failed and were replaced with lithium disilicate because of core fracture, and 10 cases of chipping occurred on the ceramic surface and were polished. The overall survival rate was 91.77% for up to 7 years of function, with a failure rate of 8.23%. In this retrospective survival analysis, the failures, including the fracture of veneers and dental hard tissue, occurred both in prep and no-prep teeth. No failures were observed in veneers with a maximum thickness of 0.5 mm compared to those with a maximum thickness of 1 mm, 1.5 mm, 2 mm, and 2.5 mm.
本研究的目的是评估使用微创技术（如垂直预备（无修复体终末线）或不预备（零预备））的长石质陶瓷贴面在7年期间的临床效果。在对牙齿和修复体进行特殊处理后，共170颗长石质陶瓷贴面粘结于前牙区，其中上颌贴面70颗，下颌贴面100颗。在2021年2月至6月召回所有患者后，使用国际牙科联合会（FDI）标准评估套件对贴面进行评估。共有14颗长石质贴面因核折裂而失败，用二硅酸锂贴面替换，10例陶瓷表面出现崩瓷并进行了抛光处理。长达7年的功能期内，总体生存率为91.77%，失败率为8.23%。在这项回顾性生存分析中，包括贴面和牙硬组织折裂在内的失败情况在预备牙和零预备牙中均有发生。与最大厚度为1mm、1.5mm、2mm和2.5mm的贴面相比，最大厚度为0.5mm的贴面未观察到失败情况。
