STRUCTURAL AND MECHANICAL ASSESSMENT OF DENTAL IMPLANTS BASED ON TiO2 AND ZrO2

At the stages of choosing a design and during the installation of a dental implant, its optimal parameters are taken into account. The determination of these parameters depends on the volume of bone tissue of the lower jaw and its mechanical properties. When choosing a design, it is necessary to assess the level of violations developing in the process of functioning. This article discusses two types of systems TiO2 implants and structures made of ZrO2. The possibility of using implants based on ZrO2 is evaluated by analyzing the stress-strain state of both the implant itself and the implant-bone zone, where large stress differences occur. This property makes it possible to ensure better compression performance of the implant during biting. In this task, the implant mainly works on bending, and the less its bending is, the less impact it will have on the bone tissue in the cervical region. It can be concluded that an implant made of ZrO2 causes less stress than an implant made of zirconium alloy under lateral loading during chewing.
