Patients' increasing interest in achieving optimal cosmetic outcomes and the widespread use of ultrathin ceramic veneers offer advantages such as high esthetic results and long-term durability. Several issues related to tooth preparation have been raised, including dental sensitivity, periodontal diseases, and increased treatment phases, in addition to complications associated with previous procedures, the treatment of which remains controversial to date. With the advancement of dental ceramic and its manufacturing techniques, it was widely used to manufacture ultrathin ceramic veneers with minimal preparation. Issues such as fracture and abfraction are the most common in ceramic veneers made of feldspathic ceramic due to their weak mechanical properties against various forces, which led to the emergence of lithium disilicate glass-ceramic manufactured using the heat-press technique. This has resulted in ultrathin ceramic veneers with a thickness of up to 0.1-0.2 mm easily bonded and finished as they have high mechanical properties and esthetic qualities that mimic natural tooth color and shape. The current cohort study aimed to evaluate the success rates of this kind of treatment for patients treated at our department.
This observational cohort study's sample comprised 60 ultrathin ceramic veneers manufactured from lithium disilicate glass-ceramic bonded to nonprepared upper teeth. The clinical performance of the studied sample was evaluated and monitored at monthly intervals (one month, three months, six months, and one year) using the clinical success evaluation based on Walton's principles adopted for evaluating the success and failure of fixed restorations.
Ultrathin ceramic veneers made from lithium disilicate glass-ceramic, bonded to nonprepared teeth, proved to be a successful clinical and esthetic treatment option, with a clinical success rate of 100% during the entire follow-up period.

患者对实现最佳美容效果的兴趣日益浓厚，超薄陶瓷贴面的广泛应用具有诸多优势，如美学效果高和长期耐用性。除了与先前治疗相关的并发症（其治疗至今仍存在争议）外，还出现了一些与牙齿预备相关的问题，包括牙齿敏感、牙周疾病以及治疗阶段增加。随着牙科陶瓷及其制造技术的进步，它被广泛用于制造只需极少预备的超薄陶瓷贴面。由于长石质陶瓷制成的陶瓷贴面在抵抗各种力时机械性能较弱，诸如折裂和磨损性折断等问题最为常见，这促使了采用热压技术制造的二硅酸锂玻璃陶瓷的出现。这使得厚度达0.1 - 0.2毫米的超薄陶瓷贴面易于粘结和修整，因为它们具有模仿天然牙齿颜色和形状的高机械性能和美学品质。当前的队列研究旨在评估在我们科室接受此类治疗的患者的成功率。
本观察性队列研究的样本包括60个由二硅酸锂玻璃陶瓷制成并粘结于未预备的上颌牙齿的超薄陶瓷贴面。使用基于沃尔顿原则的临床成功评估方法，对研究样本的临床表现进行每月一次（1个月、3个月、6个月和1年）的评估和监测，该原则用于评估固定修复体的成功与失败。
由二硅酸锂玻璃陶瓷制成并粘结于未预备牙齿的超薄陶瓷贴面，被证明是一种成功的临床和美学治疗选择，在整个随访期间临床成功率为100%。
