摘要

目前,种植体的最佳修复修复体问题对于解决许多临床疑难病例至关重要,并且已经超出了上颌和下颌完全和部分凹陷的替代治疗。这里的一个重要因素是了解种植体-基牙界面的生物力学行为,因为最佳的种植体-基牙界面模拟天然牙齿的生物物理行为,并确保假体修复的长期功能。评估种植体-基台结合部的最佳方法是静态抗拉强度法。该限制是通过在种植体-基台区域进行一次牙科种植体的加载来确定的。本研究的目的是评估可拆卸和不可拆卸的4 × 10圆柱形和锥形种植体的种植体-基台变形,并确定其静强度极限。材料和方法。选择两种品牌的种植体作为研究对象:圆柱形种植体LIKO M 4x10和锥形种植体LIKO M DG 4x10。本文研究的一个课题是可拆卸与不可拆卸基台单元的极限强度设计。对不同形状种植体的可拆卸与不可拆卸基台结构进行强度比较,并进行了估算种植体-基台单元变形极限的静载荷试验。通过对静强度的对比分析,可以在考虑载荷结构最大极限的情况下,优化种植体修复处理工艺,实现平衡载荷分布。

COMPARATIVE STATIC STRENGTH EVALUATION OF THE IMPLANT-ABUTMENT JOINTS IN DIFFERENT IMPLANT DESIGNS
Nowadays the problem of optimal restorative prosthetics on dental implants is of paramount importance for solving a number of clinically difficult cases and extends beyond the alternative treatment at the complete and partial adentia both on the upper and lower jaws. An essential factor here is understanding of the biomechanical behaviour of the implant-abutment interface, because an optimal implant-abutment interface simulates the biophysical behaviour of natural teeth and ensures the long-term function of the prosthetic restoration. The optimal method for assessing the implant-abutment junction is the static tensile strength method. The limit is determined by performing a single loading of the dental implant in the implant-abutment area.The aim of the study was to assess the implant-abutment deformation of demountable and non-demountable structures of the 4x10 cylindrical and cone-shaped dental implants with determination of their static strength limit.Materials and methods. Two brands of dental implants have been chosen as the objects of research – cylindrical implant LIKO M 4x10 and cone-shaped implant LIKO M DG 4x10. A subject of the research is the ultimate strength of the implant-abutment unit of demountable and non-demountable abutment design.Results. Static loading tests with estimation of the deformation limit of the implant-abutment unit were carried out along with the comparative estimation of the strength of demountable and non-demountable abutment constructions of dental implants of various shapes.Conclusion. The carried out comparative analysis of the static strength makes it possible to optimise the process of prosthodontic treatment on dental implants taking into account the maximal limits of the loaded structures and to carry out the equilibrium load distribution.
