The hybrid abutment emerged as an alternative to maintain a stable and favorable volume of peri-implant tissue; it is composed of a mesostructure in ceramic and a metallic connection, which can be machined according to the peri-implant emergence profile. This case report presented the clinical steps for a dental implant with immediate provisional restoration, followed by the installation of implant-supported all-ceramic crowns with zirconia abutment and platform switching. A 40-year-old male patient was rehabilitated with an implant-supported ceramic crown in the region of element 11 and a ceramic veneer was cemented on the upper right central incisor. To do so, an atraumatic extraction of the upper left central incisor was performed followed by implant placement and immediate loading. In this case, a zirconia hybrid abutment was used with a metallic link in the cervical region with a concave platform switching base. This association of clinical steps enabled improving the aesthetics in the anterior dental region.
混合基台作为一种替代方案出现,用于维持种植体周围组织稳定且良好的体积;它由陶瓷中间结构和金属连接件组成,可根据种植体周围穿出轮廓进行加工。本病例报告介绍了即刻临时修复的牙种植体的临床步骤,随后安装了带有氧化锆基台和平台转换的种植体支持全瓷冠。一名40岁男性患者在11号牙区域用种植体支持的陶瓷冠进行了修复,并在上颌右中切牙上粘结了陶瓷贴面。为此,对上颌左中切牙进行了无创拔除,随后植入种植体并即刻加载。在本病例中,使用了氧化锆混合基台,其颈部区域有金属连接,带有凹形平台转换基座。这些临床步骤的组合能够改善前牙区的美观。
