A technique is proposed for the restoration of a large and visible maxillary anterior defect. The importance of proper diagnosis, treatment planning, and communication is emphasized. Irreversible treatment should only be rendered once patient approval has been obtained through objective evaluation with provisional restorations. The techniques presented in this article use a combination of ceramic systems currently available to satisfy functional demands while achieving acceptable esthetics. A controlled series of steps, where the provisional restorative components are being replaced by the definitive ones is planned. The only difference between the provisional and definitive restorative components is the material used. The definitive restorations consisted of an implant-supported zirconium oxide framework. Individual pressed porcelain restorations were luted to the framework and a natural tooth. CLINICAL SIGNIFICANCE Provisional restorations allow an objective form of communication. Vertical and horizontal transitional lines can be effectively masked with appropriate treatment planning and a skilled ceramist. Many traditional dental laboratory steps may be eliminated or simplified without compromising the definitive restorations.
提出了一种修复大面积可见上颌前牙缺损的技术。强调了正确诊断、治疗计划和沟通的重要性。只有在通过临时修复体进行客观评估获得患者认可后,才能进行不可逆治疗。本文介绍的技术结合了目前可用的陶瓷系统,以满足功能需求,同时达到可接受的美观效果。计划采用一系列受控步骤,用最终修复体替代临时修复体。临时和最终修复体之间的唯一区别是使用的材料。最终修复体由种植体支持的氧化锆框架组成。单独压制的瓷修复体被粘接到框架和天然牙齿上。临床意义临时修复体允许进行客观的沟通。通过适当的治疗计划和熟练的技工,可有效地掩盖垂直和水平过渡线。许多传统的牙科实验室步骤可以被省略或简化,而不会影响最终修复体。
