EVALUATION OF THE EFFECTIVENESS OF APPLICATION OF FIBROUS MATRIX DURING DIRECTIONAL BONE REGENERATION OF PERIODONTAL INTRAOSSE JAW DEFECTS

Abstract

The task of periodontal therapy is to implement primary and secondary prophylaxis of periodontal diseases by controlling the factors of inflammation and maintenance and improving the condition and function of the gums, periodontal ligament, cement of the root and surrounding bones, which in the complex form the structure of the periodontal tooth. Objective. Determine the level of effectiveness and justify the feasibility of using a fibrous matrix of polylactic acid foams as an alternative approach to directed bone regeneration during the reconstruction of intraosseal periodontal defects of the jaws. Object and methods. In order to achieve this goal, the study process was divided into two interrelated stages. A complex of diagnostic (cone-ray computer research, probing, instrumental and biochemical diagnostics) and surgical manipulations was performed for the purpose of restoration of intraosse jaundice defects and control over the results of treatment. Using the randomized distribution method, the total study population was divided into the main group (29 persons – Group I) and the comparison group (27 persons – Group II). Results. In determining the level of reduction of bone defect volume in 12 months after surgery, using the data of cone-ray computer tomography and the graphic principle of superimposition, it was possible to establish that in the I group the volume of bone defect decreased by 31,19±4,07 conditional units, and in the second group – by 29.18±1.39 units. The obtained results indicate that the use of a fibrous matrix of polylactic acid foams may serve as an effective alternative for the treatment of intraosse periodontal defects in the jaws during the implementation of the directed bone regeneration procedure. Advantages of a fibrous matrix, as well as a bone substitute of xenogeneic origin, consist in the access to virtually unlimited volume of material necessary to replace the periodontal defect, eliminate the need for autologous bone tissue, reduce the level of discomfort in the patient during surgical intervention and optimize the surgical manipulation algorithm directed on the restoration of bone deficiency in the area of the periodontal affected units of the dentition. Conclusion. The implementation of the directed bone regeneration procedure with the use as the main material for filling intraosseous defects of the jaw of the fibrous matrix of polylactic acid foams is an effective alternative to the classical approaches to the surgical treatment of two- and three-wall periodontal lesions.
