Objectives To present the treatment approach for the restoration of localised anterior erosive wear using a combination of dental materials.Clinical considerations A patient presented in a private dental practice concerned about the aesthetics of his anterior teeth. The patient's history and clinical examination revealed erosive wear on the labial and palatal aspects of his maxillary central incisors and right lateral incisor. The formulated treatment plan was to restore the teeth in a conservative way. A diagnostic wax-up was performed and confirmed with the patient with chairside mock-up. The treatment provided included direct composite restorations, replacement of a porcelain-fused-to-metal crown on his left lateral incisor with a porcelain-fused-to-zirconia crown, and lithium disilicate ceramic veneers on the worn labial surfaces of the central incisors and the right lateral incisor. The preparations for the ceramic veneers were carried out with the aid of the diagnostic mock-up, thus minimising the need for tooth removal of the worn teeth.Conclusions Pre-operative planning for tooth surface loss cases can help to ensure that little or no remaining tooth structure is removed during the restorative procedures. A strict bonding protocol is crucial to ensure longevity of the restorations.
介绍使用牙科材料组合修复局限性前牙侵蚀性磨损的治疗方法。
一位患者在私人牙科诊所就诊，对其上前牙的美观感到担忧。患者的病史和临床检查显示，上颌中切牙的唇侧和腭侧以及右侧侧切牙存在侵蚀性磨损。制定的治疗计划是采用保守的方式修复牙齿。进行了诊断性蜡型，并通过椅旁模型与患者确认。提供的治疗包括直接复合树脂修复、用氧化锆全瓷冠替换左侧侧切牙的金属烤瓷冠，以及在中切牙和右侧侧切牙的唇面磨损表面上进行锂硅二硅酸酯陶瓷贴面。陶瓷贴面的预备在诊断性模型的辅助下进行，从而最大限度地减少了对磨损牙齿的牙体去除。
对于牙面损耗病例，术前规划有助于确保在修复过程中去除的剩余牙体结构很少或没有。严格的粘结方案对于确保修复体的长期效果至关重要。
