Abstract

The invention discloses a method for measurement of a bone-implant contact ratio through Microct. The method comprises measurement material selection, measurement processes, measurement result verification and measurement result analysis. Through a novel Microct technology, the novel method for measurement of a bone-implant contact ratio is created. The method can realize accurate measurement and calculation of a bone-implant contact ratio and provides a scientific basis and method for bone-implant research.

Description

technical field [0001] The invention relates to a method for measuring the bone-implant combination rate by using Microct. Background technique [0002] The biomechanical environment is one of the key factors related to the success or failure of implant treatment. The bone-implant interface stress plays an important role in the formation and reconstruction of the bone-implant. The bone tissue attraction at the edge of the implant caused by overload is the most important factor affecting the implant. One of the most important reasons for long-term success. In order to ensure the normal functional load state, a certain amount of osseointegration must be achieved between the implant and the surrounding bone tissue. This is a sign of successful implantation and also the material basis for implants to withstand various loads. Determining the minimum bone-implant interface integration rate that meets clinical functional needs is still a clinical problem that needs to be solved. ...
