Abstract
Relevance: the aim of the research was to optimize the choice of material for fabrication of temporary dentures on isoelastic implants by finite element method.
Materials and methods: four models were constructed of supporting element (basal PEEK implant, crestal PEEK implant and natural tooth in different combination) and in prototype dentures from three different materials. Areas of the maximum voltage in constructions have been revealed and possible loads have been calculated by final element method.
Results: the areas of maximum stress occur in the intraosseous part of implants in all studued cases.
Conclusions: analysis of the data shows that the stresses in crowns is practically independent of the properties of the studied temporary bridges materials. Models 1 and 3 were the strongest. Model 4 was less strong.
