ABSTRACT
Purpose.To analyze the mechanical characteristics of dental materials in comparison with enamel and dentin properties of teeth and to develop a method for qualimetric assessment of the modern biomechanical restorative materials effectiveness use in minimally invasive dental practice.
The methods. For the restorative materials quantitative assessment, a method was proposed and substantiated, based on the concept of the average harmonic ratio of the elasticity modulus, strength, crack resistance and hardness of artificial materials to the corresponding natural enamel and dentin properties.The quality indicators of enamel and dentin are accepted as equal to one. Accordingly, the closer the quality indicator of the restoration material is to one, the closer it is to the characteristics of natural material according to the selected criterion, i.e., it is the best of the options considered.
Findings. The mechanical parameters of the five restorative composite materials were systematized and calculations of the proposed complex indicator of their quality reduced to the properties of tooth enamel and dentin were carried out. A comparative analysis of the results obtained confirms the conclusion that it is impossible to assess the overall quality of the materials studied based on a single mechanical characteristic. The calculations conducted confirm the possibility of applying the proposed methodology.
The originality. Thedependencies established between the basic parameters used to evaluate the mechanical properties of dental nanocomposite materials (modulus of elasticity, strength, crack resistance, hardness)can be used to improve methods for qualimetric assessment of biomechanical materials.For qualimetric assessment of materials using the considered method, there are no fundamental restrictions on basic parameters increasing number.
Practical implementation. The results obtained from research into restorative composite materials based on a comprehensive quality indicatorcan contribute to a reliable practical assessment of existing and new dental materials to reduce risks and increase the effectiveness of their practical use.
