The teeth most commonly affected by trauma are the maxillary central incisors. The most frequent types of traumatic dental injuries to permanent teeth are enamel fractures, enamel and dentine fractures, and enamel and dentine fractures with pulp involvement. This article describes three clinical cases with different levels of traumatized maxillary incisors and several cosmetic approaches for recovery of the esthetics and the masticatory function, as well as the social/psychological aspects of treatment. All cases involved young adult men. The three clinical cases involve dentin and enamel fractures, dentin and enamel fractures with pulp exposure, and dentin and enamel fractures with pulp exposure associated with root fracture. The cosmetic treatments used to resolve fractures were direct composite resin by layering technique, indirect all-ceramic restorations (laminate veneer and ceramic crowns over the teeth), and immediate implant after extraction followed by immediate loading (ceramic abutments with ceramic crown over implant). In all three cases, excellent functional and esthetic results were achieved by use of these treatment modalities. The patients were very satisfied with the results.
最常受到创伤影响的牙齿是上颌中切牙。恒牙中最常见的外伤性牙损伤类型是釉质裂、釉质和牙本质裂以及伴有牙髓受累的釉质和牙本质裂。本文描述了 3 例上颌切牙不同程度外伤的临床病例,并介绍了几种恢复美观和咀嚼功能的美容方法,以及治疗的社会/心理方面。所有病例均涉及年轻成年男性。这 3 个临床病例涉及牙本质和釉质裂、牙本质和釉质裂伴有牙髓暴露以及牙本质和釉质裂伴有牙髓暴露伴根折。用于解决骨折的美容治疗方法是分层技术的直接复合树脂、间接全陶瓷修复体(贴面和牙冠覆盖牙齿)以及拔牙后即刻植入物即刻负载(种植体上的陶瓷基台和陶瓷冠)。通过使用这些治疗方法,所有 3 例均获得了极佳的功能和美观效果。患者对结果非常满意。
