Abstract

Surface bone remodeling theory and the boundary element method are employed to investigate the microstructural remodeling of bone at the bone-implant interface. Three situations are considered: remodeling-induced penetration between the screw threads of an implanted screw, penetration of bone tissue into a slot or cavity in an implant, and the interaction of individual trabeculae in the remodeling processes near an implant. For each case the bone ingrowth is determined as a function of the geometry and the applied load.

摘要

采用表面骨重塑理论和边界元方法研究骨-植入物界面处骨的微观结构重塑。考虑了三种情况：植入螺钉螺纹之间因重塑引起的穿透、骨组织向植入物中的狭槽或腔的穿透，以及植入物附近重塑过程中单个小梁的相互作用。对于每种情况，骨长入根据几何形状和所施加的载荷确定。
