CLINICAL EVALUATION OF THE EFFICIENCY OF ORTHOPEDIC TREATMENT OF PATIENTS WITH EDENTULOUS JAWS WITH COMPLETE REMOVABLE DENTURES USING C-SILICONE MATERIALS FOR FUNCTIONAL IMPRESSIONS
Introduction. Prosthetics of edentulous jaw is one of the most difficult sections of prosthetic dentistry for many years. The difficulty lies in the production of functionally effective complete dentures that are in direct proportion to their fixation on the jaws, stabilization during chewing and even distribution of pressure on the underlying tissues.
The aim of this research was to conduct a comparative clinical evaluation of the efficiency of the complete removable laminar dentures that were made with use of the new materials for functional impressions.
Methods. At the stages of clinical application of new silicon functional impression materials we examined and conducted prosthetic treatment of 48 edentulous patients of both sexes 50 - 75 years old with complete removable laminar dentures with different state of the mucous membrane of the prosthetic area, different degree of atrophy of the alveolar process.
We obtained functional impressions with silicone material for anatomical impressions Stomaflex Pasta (Spofa Dental, Czech Republic) in the control group. In the main group we obtained functional impression with new silicone materials for functional impressions "Stomasil and Stomasil-D" that we created. The complete removable dentures were manufactured according to the standard technique.
Results. Comparing the average chewing efficiency throughout the observation period, we notice that the improvement in chewing function in group b more than group A: subgroup A1 - by 18,84%, subgroup B1 - by 25,06%, subgroup A2 by 19,34%, subgroup B2 – 21,73%.
Thus, we determine that in the main group time indicators of chewing in the first month after the imposition of the prosthesis significantly reduced compared to the control group. Next time indicators of mastication do not change during the study patients and gaining stability in all subgroups.
Conclusions. Comparative clinical evaluation of the efficiency of prosthetic treatment of edentulous patients with complete removable dentures using C-silicon materials for functional impressions allowed to prove that the dentures, which were made with our new impression materials for functional impressions, restore chewing function better, and adaptation to the dentures occurs faster than in the control groups. It is seen clearly when we are comparing the average index of chewing on the first day, after 1 week, 1 month and 3 months. Also should be noted that the improvement of the chewing function in group B more than that in group A. Thus, the use of the target material for functional impressions helped to improve the quality of prosthetics edentulous jaws.
