Experimental study of fine-grained reticulated titanium nickelide in the near-defective tissues of the palate

Abstract

Aim. To study the peculiarities of regeneration of fine-gauge reticulated titanium nickelide in near-defective tissues of the palate.
Material and methods. The work was carried out on 10 female rabbits of the Shin Shila breed weighing 2,7-3,0 kg; an experimental investigation was carried out in the Central Research Laboratory of the Avicenna Tajik State Medical University. As the implantation material, we used a fine mesh titanium nickelide with a thickness of 40-50 microns threads and the size of 50x50 microns cells.
Results and discussion. The morphological study revealed that after the surgery the mucous membrane covering the implant was edematous with foci of hyperemia and hemorrhages. Vessels were dilated and full-blooded, small and medium caliber vessels were constricted. In the zone of anastomosis, there were prevailing changes of inflammatory character with slight activation of local immunity. Fifteen days later the mucous membrane in the anastomosis zone partially recovered. Local immunity activation contributes to the restoration of normal structures in the implant area. Later it was noticed that as soon as blood supply to the implant zone was restored almost immediately from the areas bordering the operation zone the sprouting of the covering epithelium cells began.
Conclusion. Regeneration processes in the artificially created defective areas of the palate, at the use of the titanium fine mesh nickelide begin on the border of the implant material contact with the tissues of the peri-defective zone at the expense of the local immune reactions activation with the following gradual transition to the other areas.
