This article describes an alternative technique for the fabrication of an implant-supported, screw-retained, fixed provisional restoration in the esthetic zone. After an implant-level impression is made with a polyether impression material, the provisional restoration is fabricated indirectly. This technique is easy, saves time, and has economic advantages, while maintaining color stability and esthetic properties for the provisional restoration. It may be contraindicated for severely misaligned implants that require extensive reduction of the implant temporary abutments and denture teeth laminates.
本文介绍了一种在美学区域制作种植体支持的、螺丝固位的、固定临时修复体的替代技术。使用聚醚印模材料进行种植体水平印模后,间接制作临时修复体。该技术简便、省时,具有经济优势,同时保持临时修复体的颜色稳定性和美学性能。对于需要大量减少种植体临时基台和义齿牙层的严重错位种植体,可能存在禁忌。
