OBJECTIVE

To study the kinetics of mucosal blood flow in 3D modeling of the gingival contour around dental implants after bone reconstruction of the alveolar ridge in the posterior jaw.

MATERIAL AND METHODS

The work was performed at the clinical base of the Department of Surgical Dentistry and Maxillofacial Surgery of the Institute of Dentistry of the Privolzhsky Research Medical University, Nizhny Novgorod, Russia with the participation of 87 patients who were divided into two groups depending on the chosen method of treatment and a control group. The method of laser Doppler flowmetry was carried out using a multifunctional laser diagnostic complex LAKK-02. The terms of observation were 7, 14, 28, 42 days.

RESULTS

On the 7th postoperative day, the decrease in microcirculation index (MI) in the groups reflected moderately pronounced hemodynamic disorders with a predominance of a decrease in MI in the center (by 35.8%). The predominance of the stagnant-ischemic type of microcirculation disorders and low intensity of neoangiogenesis was established, especially in the central zone in group 1, and in group 2 signs of neoangiogenesis were noted by the 7th day. By the 14th day, there was a decrease in venous congestion and signs of arterial inflow. In the 2nd group there was a subsidence of inflammatory phenomena and an increase in the energy of the oscillatory process in the vessels. Gradually, by the 42nd day, the indicators in groups 1 and 2 approached in value to the control group and did not differ significantly.

CONCLUSION

A previously unknown mechanism of interaction between two heterogeneous grafts (xenograft and thin free gingival graft) was revealed, which determined neoangiogenesis by the traditional method (from the center to the periphery), and by the proposed method (from the periphery to the center). Understanding the wound process is necessary for the purpose of further correction of the surgical technique for the best restoration of the vascular network and an increase in the success rate of operations.
