Introduction. Topical task of modern orthopedic treatment of patients by removable structures is to increase the functional efficiency of prostheses and prevention of atrophic changes supporting tissues prosthetic bed.

The definition of chewing pressure - an important criterion for research of the functional state of dental system for violations of occlusion, neuromuscular syndrome, restoring the dentition with removable and fixed structures, treatment with implants.

The aim of this study was to improve the method for evaluating chewing pressure on the stages of orthopedic treatment due to clinical use of a special device.

Materials and methods. To improve the method for evaluating chewing pressure used a special device "BNV-02" - is a mechanical method of recording chewing pressure between the teeth-antagonists in different parts of the dentition with the evaluation redistribution chewing load in the early and late periods (ISO 10139-2). For the generalized analysis of the received results was calculated the average value and its average error, also was applied the index analysis of chewing pressure indicators for each of the groups of defects of the dentition. Clinical application of the developed device was performed in 57 patients who were made dentures, and who needs the correction of denture base. The first measurement was performed to manufacture orthopedic construction, the second in the early (immediately after the manufacture of the prosthesis) and distant (30-45 days) during the treatment period.

Conclusions. In the process, it was revealed that orthopedic treatment by removable dentures of dentition defects in various localization provides an increase of chewing pressure with its uniform distribution on the symmetric parts regardless of the extent and location of generated through dentition defect. To evaluate the uniformity of the distribution of chewing pressure on different parts of the dentition was proposed standardized symmetry index, which reflects the emerging under the influence of compensatory adaptation effects.

Prospects of job in this thread obvious, since further researchs of chewing pressure will provide its response in relation to the constitutionally - biological (sex, age, diet), clinical factors (prescription of defect, state of the prosthetic field), as well as to obtain data about the coordinate chewing features pressure on areas of the dentition.
