Based on clinical observation, a hypothesis of the mechanism of intrusion of natural teeth in an implant-assisted prosthesis is suggested. Engineering principles are presented that establish an energy absorption model as it relates to the implant-assisted prosthesis. In addition, in the course of patient treatment it has been discovered that the intrusion of natural teeth can be reversed. Patient histories that demonstrate intrusion reversal are reviewed. The possible mechanisms for the intrusion/reversal phenomenon are presented and preventative recommendations are given.
基于临床观察，提出了天然牙在种植体支持修复体中发生侵入的机制假说。阐述了与种植体支持修复体相关的建立能量吸收模型的工程原理。此外，在患者治疗过程中发现天然牙的侵入是可以逆转的。回顾了显示侵入逆转的患者病史。介绍了侵入/逆转现象的可能机制并给出了预防建议。
