Patients with challenging prosthodontic conditions require rehabilitation with a biological, functional, and esthetic approach. When one or more teeth are badly discolored, their restoration is problematic because poor appearance affects not only the crown but also the periodontal tissues. This clinical report describes a complex esthetic rehabilitation with conservative tissue management and ceramic restorations. Subepithelial connective tissue graft surgery and the replacement of a cast metal post with a glass fiber post addressed the problem of a discolored maxillary central incisor. The discolored right maxillary incisor was restored with a combination of a medium-opaque, lithium-disilicate ceramic coping to mask the dark root and to approximate the color of the other incisors. Subsequently, 6 ceramic veneers were placed. A knowledge of the materials' optical properties and adhesion possibilities helped solve this complex problem.
患有复杂修复条件的患者需要采用生物、功能和美观的方法进行康复治疗。当一颗或多颗牙齿严重变色时，其修复就成了问题，因为外观不佳不仅会影响牙冠，还会影响牙周组织。本临床报告描述了一项复杂的美学修复，采用了保守的组织管理和陶瓷修复体。上皮下结缔组织移植术和用玻璃纤维桩代替铸造金属桩解决了上颌中切牙变色的问题。变色的右上颌中切牙通过使用中等不透明的锂硅瓷贴面来遮盖深色的根部并接近其他切牙的颜色进行修复。随后，放置了 6 个陶瓷贴面。对材料光学性能和黏附可能性的了解有助于解决这个复杂的问题。
