问题陈述。在高度萎缩的上颌骨中，牙种植体失败率更高。假设较高的失败率与应变驱动的适应有关，加强对形成性骨对负荷的反应(建模)和保持完整状态(重塑)的理解应该会改善治疗。为了了解咬合负荷在松质骨受损区域的长期骨整合中的作用，我们回顾了自适应骨建模和重塑的显著特征，重点介绍了松质骨的响应。种植体在上颌骨中保持长期稳定的界面的能力在于骨小梁的局部材料(强度)和结构(连通性)特性的保持能力。在这一讨论中，重点是了解松质骨如何对咀嚼诱导的种植体加载环境做出反应。
Statement of problem. Dental implant failure rates for osseointegration are greater in the highly atrophic maxilla. Presuming higher failure rates relate to strain driven adaptation, an enhanced understanding of formative bone response to loading (modeling) and maintenance of an integrated state (remodeling) should improve treatment.Purpose. To understand the role of occlusal loading on long-term osseointegration in areas of compromised cancellous bone, a review of the salient features of adaptive bone modeling and remodeling is presented with an emphasis on cancellous bone responses.Conclusions. The ability for dental implants to maintain a long-term stable interface in the maxilla lies in the ability of trabecular bane to maintain adequate local material (strength) and architectural (connectivity) properties. In this discussion, an emphasis has been placed on understanding how trabecular bone can respond to the mastication-induced loading environment on an implant.
