Whether ultrathin ceramic veneers are a suitable treatment alternative to conventional ceramic veneers is unclear.
The purpose of this prospective clinical cohort study was to evaluate the efficacy and longevity of nonpreparation and minimally invasive ceramic veneers and the influence of existing restorations and ceramic type and to define the relationship between the number of veneers placed on different teeth and in different locations, as well as age and sex correlations.
A total of 801 veneers were placed on incisors, canines, and premolars on maxillary and mandibular teeth between January 2011 and August 2019 (ABR number: RNN/92/19/KE). Feldspathic or feldspathic and lithium disilicate veneers were made, etched, silanated, and cemented. The restorations were evaluated 2 weeks after placement and then every 6 months by using the modified United States Public Health Service (USPHS) criteria. The relationship between participant age and number of veneers was analyzed by using the Spearman rank coefficient test and the Mann-Whitney U test. Changes in the number of participants and veneers in subsequent years were analyzed based on the Spearman rank correlation coefficient. The trend between the location of veneers and the sex of the participants was analyzed by using the chi-squared test for trend. Longevity tables and a survival curve for the veneers were prepared based on the Kaplan-Meier method. The relationships between veneer longevity and the type of ceramic used and the presence of restorations were compared by using the Taron-Ware test (α=.05).
The mean longevity of the intact veneers was 8.45 years. Clinical success was 99.7% after 1 year and 97.9% after 4 years; this value remained constant until the end of the study. Most participants were women (n=122; 84.1%), and the mean age was 41 years; median 40 years. The number of veneers placed on mandibular teeth each year increased over the subsequent years.
The longevity of ultrathin veneers after 9 years of observation was not related to the ceramic used or to the presence of a composite resin restoration. Veneers were more commonly placed in middle-aged women and in mandibular anterior teeth.
超薄陶瓷贴面是否是传统陶瓷贴面的合适替代治疗方法尚不清楚。
本前瞻性临床队列研究的目的是评估非预备和微创陶瓷贴面的疗效和持久性，以及现有修复体、陶瓷类型的影响，并确定在不同牙齿和不同位置放置的贴面数量之间的关系，以及年龄和性别相关性。
2011 年 1 月至 2019 年 8 月（ABR 编号：RNN/92/19/KE）期间，在上颌和下颌牙齿的切牙、尖牙和前磨牙上共放置了 801 个贴面。制作长石质或长石质和锂硅玻璃陶瓷贴面，酸蚀、硅烷化、粘结。修复体在放置后 2 周和之后每 6 个月使用改良美国公共卫生服务（USPHS）标准进行评估。使用 Spearman 秩相关系数检验和 Mann-Whitney U 检验分析参与者年龄与贴面数量之间的关系。根据 Spearman 秩相关系数分析后续年份参与者和贴面数量的变化。使用趋势 χ²检验分析贴面位置与参与者性别的关系。根据 Kaplan-Meier 法制作贴面寿命表和生存曲线。使用 Taron-Ware 检验（α=.05）比较贴面寿命与所用陶瓷类型和修复体存在的关系。
完整贴面的平均寿命为 8.45 年。第 1 年临床成功率为 99.7%，第 4 年为 97.9%；该值一直保持到研究结束。大多数参与者为女性（n=122；84.1%），平均年龄为 41 岁；中位数为 40 岁。每年放置在下颌牙齿上的贴面数量逐年增加。
经过 9 年的观察，超薄贴面的使用寿命与所用陶瓷类型或复合树脂修复体的存在无关。贴面更常见于中年女性和下颌前牙。
