Elimination Of Post-Extraction Atrophy And Deformation Of The Alveolar Part Of The Jaw By Injecting Osteoplastic Materials

Post-extraction atrophy and deformation of the alveolar ridge of the jaws continues to be a serious problem in dentistry. Surgical treatment of these conditions is associated with the need to use autoplastic material, which causes certain difficulties. The injectable route of administration of osteoplasts seems to be less traumatic. However, to date, it has not found its wide application. The aim of the study was to evaluate the effectiveness of the method of eliminating post-extraction atrophy and deformation of the alveolar process by injecting osteoplastic materials on the example of platelet-rich autoplasma (PRP) and a suspension of a synthetic osteoplastic drug (Collapan). 68 patients with a limited postextraction defect or atrophy of the alveolar part of the jaw were treated and examined. Osteoplastic materials (PRP and Collapan) were injected into the bone defect area under the periosteum. In the conditions of the clinic, the effectiveness of the proposed injection method of combined administration of osteoplastic materials was established, which is expressed in the activation of bone regeneration processes with partial restoration of the lost volumes of the alveolar ridge, which is achieved due to the increased concentration in PRP of a complex of growth factors that ensure the implementation of the osteoinductive functions of the used graft, as well as the osteoconductive effect of a synthetic bioresorbable bone drug (Collapan).
