Acid-etched zirconia has emerged as a high-strength alternative to traditional glass ceramics for laminate veneers in aesthetic dentistry. This randomized, double-blind controlled clinical trial aimed to evaluate the one-year clinical performance of zirconia veneers etched with a hydrofluoric-nitric acid mixture and bonded using a 10-methacryloyloxydecyl dihydrogen phosphate (MDP) containing polymeric adhesive system, compared to lithium disilicate veneers. Fifty-two patients were treated with either translucent zirconia or lithium disilicate veneers, and restorations were bonded using light-cured resin-based adhesives. Clinical parameters, including veneer survival, esthetics, marginal adaptation, postoperative sensitivity, and periodontal health, were assessed using modified United States Public Health Service (USPHS) criteria and periodontal indexes at 2 weeks, 6 months, and 12 months. Both materials showed high survival rates with no statistically significant differences in clinical outcomes. One zirconia veneer debonded early but was successfully rebonded without fracture, while one lithium disilicate veneer fractured upon debonding. The findings support the viability of acid-etched zirconia veneers bonded with polymer-based adhesives as a durable and esthetic restorative option. The study highlights the clinical relevance of polymeric bonding systems in enhancing zirconia veneer performance and reinforces their role in modern adhesive dentistry.
在口腔美学修复中，酸蚀处理的氧化锆已成为传统玻璃陶瓷用于贴面修复的一种高强度替代材料。本随机双盲对照临床试验旨在评估，与二硅酸锂贴面相比，用氢氟酸 - 硝酸混合液蚀刻并用含10 - 甲基丙烯酰氧基癸基磷酸二氢酯（MDP）的聚合粘结系统粘结的氧化锆贴面的一年期临床性能。52例患者接受了半透明氧化锆或二硅酸锂贴面修复，修复体采用光固化树脂基粘结剂粘结。使用改良的美国公共卫生服务（USPHS）标准和牙周指数，在2周、6个月和12个月时评估临床参数，包括贴面存留率、美观度、边缘适合性、术后敏感性和牙周健康状况。两种材料均显示出高存留率，临床结果无统计学显著差异。1例氧化锆贴面早期脱粘，但成功重新粘结且未发生断裂，而1例二硅酸锂贴面在脱粘时发生了断裂。研究结果支持了用聚合物基粘结剂粘结的酸蚀氧化锆贴面作为一种持久且美观的修复选择的可行性。该研究强调了聚合粘结系统在提高氧化锆贴面性能方面的临床相关性，并强化了它们在现代粘结牙科中的作用。
