Interdisciplinary system approach and concept of experimental and analytical method of material selection and design planning in order to improve effectiveness of periodontitis treatment

Abstract

Objective. One of the most important tasks of dentistry at the present stage is creation of structures, which ensure a unity of dental system form and function and bring it closer to its original natural state. This approach permits to expand significantly the range of orthopedic treatment tasks and implement medical and technical requirements for materials, structures of dentures and splinting devices.

Materials and methods. The article reflects the results of an experimental study to determine the Poisson's ratio of the Dental D thermoplastic material used as a structural material for the manufacture of a new therapeutic and preventive dental splint as well as a biomechanical analysis of changes in the displacement amplitude of the teeth included in the splint.

Results. As a result, an accurate quantitative assessment of the developed method of tooth immobilization in mild periodontitis is given taking into account the behavior of the bone tissue of the lower jaw, hard tissues of the teeth and periodontium as well as in case when the dentition is affected by the chewing load.

Conclusions. The analysis of the obtained data allowed us to form practical recommendations for use of the developed design at the stages of orthopedic treatment of patients with the initial stage of periodontal pathology in order to reduce functional overload of dentition and maintain mobility of teeth at physiological level.
