The purpose of this document is to clarify the biomechanical principles involved when zygoma implants are placed under functional loads.
Two independent reviewers conducted electronic search of the literature from January 2000 to February 2023 describing the biomechanical principles involved using the zygoma implant for maxillary reconstruction. Articles describing the stresses within the zygoma implant, the maxillary bone and the zygoma bone under functional loads were included.
The lack of maxillary boney support at the implant platform resulted in significant higher stress measured within the zygoma implant as well as the zygoma bone.
The maxilla is the primary support when zygoma implants are placed under functional loads. Quad-cortical stabilization of the zygoma implants and their cross-arch stabilization are recommended to reduce the degree of stress whenever possible.
本文旨在阐明在功能负荷下放置颧骨种植体时涉及的生物力学原理。
两名独立的审查员对 2000 年 1 月至 2023 年 2 月期间描述使用颧骨植入物进行上颌骨重建时涉及的生物力学原理的文献进行了电子检索。纳入了描述在功能负荷下颧骨植入物、上颌骨和颧骨骨内的应力的文章。
在植入物平台处缺乏上颌骨骨支持导致在颧骨植入物以及颧骨骨内测量到的显著更高的应力。
当颧骨植入物承受功能负荷时,上颌骨是主要的支撑。建议尽可能使用四皮质稳定颧骨植入物及其交叉拱形稳定来降低应力程度。
