Opportunities to increase prosthetic treatment efficiency by means of applying osseointegrated implants of traditional and prospective types are analysed. A technique of mathematical modelling of the interaction between implants and jaw bone is exposed. The numerical model and applied program, developed on the basis of finite element method, enabling to analyse a stress strain state of the bone and to determine extreme safe loads on implants are described. It is shown, that the most loaded zone is a layer of the compact bone directly contiguous to the neck of the implant. That is in good agreement with the results of clinical research, according to which just this zone has the highest percentage of complications. Methods for further optimisation of implants and prosthetic structures for the purpose to perfect the techniques of prosthetic treatment are discussed.
分析了通过应用传统和预期类型的骨整合植入物来提高修复治疗效率的机会。阐述了植入物与颌骨相互作用的数学建模技术。描述了基于有限元方法开发的数值模型和应用程序,该模型和程序能够分析骨的应力应变状态并确定植入物上的极限安全载荷。结果表明,负荷最大的区域是紧邻植入物颈部的致密骨层。这与临床研究结果高度一致,根据临床研究,正是这个区域的并发症发生率最高。讨论了为完善修复治疗技术而进一步优化植入物和修复结构的方法。
