ATHROPHY DEGREE OF ALVEOLAR VESTIBULAR PLATE AT EARLY AND LATE TERMS AFTER TOOTH EXTRACTION

Aim. To carry out clinicofunctional estimation of the hard and soft tissue status in the region of the removed teeth sockets; 453 patients aged 30 to 45 years with diagnosed chronic apical periodontitis were examined. Materials and methods. Complex examination of patients included clinical, functional and roentgenological methods. Regional hemodynamics in the region of the first lower molar sockets was assessed before tooth extraction, 4 weeks, 3, 6 and 12 months after it using the method of ultrasonic high-frequency dopplerography (apparatus Minimax-Doppler-Phono). Results. The conducted studies indicated that the most optimal terms for dental implantation is the period from 4 weeks to 3 month, when the level of bone tissue atrophy does not exceed 2 mm. In case of delayed implantation - 3 months and longer, there occurs a significant resorption of the bone tissue that requires additional reconstructive interventions, and consequently, prolongation of treatment and increased costs. Conclusions. Regional hemodynamic indices gradually fall at both early and late terms following the teeth extraction; it manifests impairment of microcirculation in the tissues and gingival atrophy.
