CLINICAL CLASSIFICATION OF TORUS AND EFFECTIVENESS OF TWO-LAYER BASES IN REMOVABLE DENTURES

Abstract

n to the clinical manifestation of the torus and its sensitivity, to determine the effectiveness of the use of two-layer bases in removable prosthetics.

METHODS: In the clinic of orthopedic dentistry, 104 people were examined and received orthopedic treatment, including 37 patients in the comparison group. The main number of patients complained of poor fixation and violation of the chewing process (up to 55.3). In order to improve the functional efficiency of the removable prosthesis, two-layer bases using soft linings Gossil (Russia), Furji (Japan), and Mucopren (Germany) are proposed. Conducted clinical and laboratory studies (Estesmary, gattingeri, physico-mechanical studies of soft linings). The effectiveness of using soft pads in removable prosthetics is shown. The conducted research allowed creating a clinical classification of the torus depending on the pain sensitivity of the oral mucosa. Type I-painless torus, type II-moderately painful, type III-painful when touched. The features of the technology for manufacturing two-layer bases for the II, III-type of torus are recommended.

RESULTS: it was found that 47.9% of patients in the comparison group, 55.3% of those examined in the main group complained about impaired chewing and poor fixation of dentures on the upper and lower jaws, depending on the condition of oral tissues. The patients did not always objectively assess the condition of their dentures. Patients complained about lack of stabilization, poor quality dentures and the need to replace the old denture with a new one in 13.8 % of cases in the control group and 31.9 % in the main group of patients examined.

Conclusion: In the case of removable denture wearers with a total lack of teeth, there were 55.3% complaints of chewing disorders and poor fixation of dentures, and in the case of partially removable denture wearers, the greatest number of complaints of clasp fixation disorders were found in 42.1% of cases. Physico-mechanical study of soft linings from different countries, Gossil (Russia), Fuji (Japan), Mukopren (Germany), showed their effectiveness and the possibility of their use in the clinic of orthopedic dentistry.
