The use of dental ceramics on anterior teeth is associated with predictable and long-lasting esthetic results. However, treatment on darkened substrates is challenging. Various conservative options, including ceramic veneers, are available to change the shape and color of anterior teeth. The aim of this case report is to describe the esthetic rehabilitation of a darkened central incisor in a maxillary anterior region that had irregular gingival contours, multiple composite resin restorations, and unsatisfactory tooth shapes. Harmony was restored through periodontal recontouring surgery, placement of a lithium disilicate crown (consisting of a veneer cemented to a coping) on the darkened central incisor, and placement of lithium disilicate veneers on the other maxillary anterior teeth.
在前牙使用牙科陶瓷可获得可预测且持久的美观效果。然而，对于深色基底的治疗具有挑战性。有多种保守选择，包括陶瓷贴面，可以改变前牙的形状和颜色。本病例报告的目的是描述上颌前牙区一颗变色中切牙的美学修复，该中切牙具有不规则的牙龈轮廓、多个复合树脂修复体和不满意的牙齿形状。通过牙周整形手术、在变色的中切牙上放置锂硅二酸盐冠（由粘接到基底上的贴面组成）以及在前牙其他牙齿上放置锂硅二酸盐贴面来恢复美观。
