FEATURES OF THE INTERACTION OF BONE TISSUES AND SCREW DENTAL IMPLANTS MADE OF TITANIUM NICKELIDE WITH PERMEABLE POROSITY IN COMBINATION WITH FINE-PROFILE MESH TITANIUM NICKELIDE

Abstract

Goal. To study the patterns of interaction between the bone structures of the recipient zones and screw dental implants made of titanium nickelide having through permeable porosity in combination with fine-profile mesh titanium nickelide. Materials and methods. Experimental studies were performed on 15 mongrel rabbits of both sexes aged 1-1.5 years. Cylindrical porous screw nickel-titanium implants were installed in the thickness of the mandibular bone in combination with knitted thin-profile superelastic mesh titanium nickelide. To study the features of reparative osteogenesis, the material was collected 7, 14, 21, 28, 35 and 42 days after the implants were installed. Results. The conducted studies have shown that in the implantation zone the regenerate was a spongy and compact bone tissue in accordance with the localization, closer or further from the compact layer of the recipient bone. Conclusion. Due to the biocompatibility of titanium nickelide-based alloys with biological tissues, bone tissue from the recipient regions grows into the system of the porous part of the implantable structures and into the thickness of the mesh structure of thin-profile knitted titanium nickelide with the formation of a single bone organotypic regenerate between them.
