Amelogenesis imperfecta (AI) is a heterogeneous group of conditions characterized by inherited developmental defects of enamel. Patients with AI often have progressive and severe loss of occlusal vertical dimensions (OVD), resulting in challenging dental rehabilitation. In this case report, we present the management of a 24-year-old male patient who previously underwent orthodontics, direct and indirect restorations, and continued to have progressive tooth wear. His vertical dimensions were restored in two phases, firstly with provisional restorations at the improved OVD, followed by a combination of monolithic zirconia and lithium disilicate full-coverage crowns. A removable acrylic appliance was then constructed to protect his teeth. This report emphasizes the importance of preserving and protecting the OVD from an early age to prevent more costly and complicated management in future.
牙釉质发育不全（AI）是一组异质性疾病，其特征为牙釉质的遗传性发育缺陷。AI患者通常会出现渐进性且严重的咬合垂直距离（OVD）丧失，导致牙齿修复面临挑战。在本病例报告中，我们介绍了一名24岁男性患者的治疗情况，该患者此前接受过正畸治疗、直接和间接修复，但仍持续出现牙齿渐进性磨损。他的垂直距离分两个阶段进行恢复，首先在改善后的OVD处使用临时修复体，随后采用整体氧化锆和二硅酸锂全冠修复相结合的方式。然后制作了一个可摘丙烯酸矫治器来保护他的牙齿。本报告强调了从幼年起就保存和保护OVD的重要性，以防止未来出现更昂贵和复杂的治疗。
