A variety of removable prostheses is available to restore the dentition which exhibits wear and extensive loss of teeth from the arch. Such treatment may be either interceptive or transitional in order to stabilise the occlusion or definitive as part of rehabilitation. Tooth surface loss may necessitate crowning with the provision of conventional removable partial dentures or decoronation and the use of overdentures. Extensive loading generated by parafunction is often considered to risk the failure of restorations stabilised by implants and so may contra-indicate treatment. Screening out unsuitable cases appears to result in few incidents of implant failure and new designs may further reduce the risk.
有多种可摘义齿可用于修复牙列，该牙列存在磨损且牙弓中有大量牙齿缺失。这种治疗可以是预防性的或过渡性的，以稳定咬合，也可以是确定性的，作为康复治疗的一部分。牙面磨损可能需要进行牙冠修复，同时提供传统的可摘局部义齿，或进行去冠修复并使用覆盖义齿。由异常功能产生的过大负荷通常被认为会使通过种植体固定的修复体有失败的风险，因此可能不适合进行该治疗。筛选出不合适的病例似乎可减少种植体失败的发生率，新的设计可能会进一步降低风险。
