The treatment of patients with severe forms of amelogenesis imperfecta presents an interesting challenge to the dental team. A 16-year-old girl presented with a severely compromised occlusion and poor esthetics that had lowered her self-esteem. Preoperative investigations included the determination of completion of growth, an accurate diagnostic waxup, and an evaluation of clinical crown lengths. Periodontal full-flap surgery was planned to lengthen clinical crowns and create gingival harmony. This was to be followed by placement of 28 complete crowns to restore occlusal function and gain a pleasing esthetic result. All-porcelain crowns were placed from premolar to premolar in each arch (20 crowns), and porcelain-fused-to-metal crowns were placed on each molar tooth in each arch (8 crowns). The final treatment result provided this patient with a mutually protective occlusion and with esthetics that greatly enhanced her self-image.
对患有严重型牙釉质发育不全的患者进行治疗,对牙科团队来说是一项有趣的挑战。一名16岁女孩就诊时存在严重的咬合功能受损和美观问题,这降低了她的自尊。术前检查包括确定生长是否完成、精确的诊断性排牙以及评估临床冠长度。计划进行牙周全翻瓣手术以延长临床冠并实现牙龈协调。接下来要放置28颗全冠来恢复咬合功能并获得令人满意的美观效果。在每个牙弓中,从双尖牙到双尖牙放置全瓷冠(共20颗冠),在每个牙弓的每颗磨牙上放置烤瓷熔附金属冠(共8颗冠)。最终的治疗结果为该患者提供了相互保护的咬合关系,并极大地提升了她自我形象的美观度。
