The purpose of the study. Efficiency of clinical effective of combined denture (polypropylene plastics and acrylic) in partial defect of dentition.
Material and methods. Developed design of denture consist of frame made with copolymer polypropylene frame like bugel prosthetic, supported-holding clasps, retention saddles made of the same material, basis made acrylic plastics, plastic artificial teeth, fixed in the base. We investigated these indicators in the group of four patients with dentition defects class 1 and 2 by Kennedy with no less than 6 teeth. In the first group of prosthetic was made partial acrylic dentures (plastic “Ftoraks”), in the second group used a clasp prostheses with clasps Roach and Acker (alloy “Remanium” and plastic “Ftoraks”), the third group — patients with partial laminar dentures of copolymer polypropylene. The fourth group consisted of patients with partial laminar dentures made by the above method.
Results. Assessing the dynamics of the resistance of the capillaries in the fourth group, it was noted that the resistance of the capillaries when applying prostheses remained virtually unchanged. The findings suggest that a much smaller negative impact of bases dentures is in the II and IV groups, due to design features (a much smaller base area, supporting-retaining clasps) in these study groups. Patients with polypropylene prosthesis showed almost similar pattern as in the second research group. But patients who were using combined dentures, periodontal restored optimal state for 1 month of prostheses use (to the level of 0.76±0.05). In 1 year index of the intensity of periodontal tissue inflammation returned to normal.
