STUDY OF TISSUE HEMODYNAMIC PARAMETERS IN DIFFERENT TYPES OF PERIODONTAL SPLINTING

Introduction. One of the most effective treatments for chronic generalized periodontitis is splinted teeth. Especially — splinting fiberglass. However, existing methods have a number of drawbacks, including: frequent breakdowns, the bundle of fibers fiberglass, can be separated from the tire of individual teeth, poor hygiene as well.

The purpose is improvement of methods of splinting teeth with generalized periodontitis glass string and evaluate the effectiveness of comparative study of the vascular bed of the alveolar gingiva in this type of splinting.

Research methods. The author proposed a method of manufacturing fiberglass tire laboratory method using photopolymerization threads under additional overpressure.

All patients for these studies were divided into three groups: using thread “Poliglas” (Russian), thread “Connect” (Kerr, USA), and splinting of our own technique.

During studying microcirculation parameters we conducted measurements under three sites: at the center area between the two extremes of splinting teeth, which is under the tire, on the end of the teeth in the center of the alveolar distance. This measures the average blood velocity (Vm), peripheral resistance index (PRI) and the index pulse (IP).

Results. Our study showed that splinting structures made of both the thread “Connect”, and according to our technology function in the oral cavity of patients with periodontal disease without significant hemodynamic changes of bloodstream. Then, with further functioning of dentition with splinting thread “Poliglas” there was marked reduction in Vm and deterioration of indices that characterize elastic properties of microvessels. Those changes were quite significant, and further clinical deterioration of prosthetic bed takes place, which is confirmed by Doppler indices.

Conclusion. The obtained comparative data show the positive effect of the proposed splinting method on tissue prosthetic bed, which allows us to recommend it for general use.
