Effect of autologous modification of dental implants based on non-woven titanium material with a through porosity on the primary stability indices in experiment

Abstract

The aim of the investigation is to compare primary stability values of dental implant models based on titanium non-woven material with a through porosity mounted by traditional technology and the technology of autologous modification in experiment. Materials and Methods. A randomized study was performed on 18 mandible models of pigs aged 9 to 13 months. Periotestometry method was used for comparative assessment of primary stability of dental implant models based on non-woven titanium material with a through porosity placed by traditional technology (the first series of tests, n=18) and that of autologous modification (the second series of tests, n=18). The diameter of pin spacers was 1.8; 2.0; 2.3 mm. Results. Pin spacer diameter increase from 1.8 mm to 2.3 mm in dental implant models with titanium sleeves made of non-woven material with a through porosity increases stability values by 7.8 times, whereas for implant models with the sleeves made of the same non-woven titanium material but modified by autologous bone tissue — by 10.06 times. Autologous bone modification of titanium non-woven material with a through porosity increases stability indices of an implant with a pin spacer diameter of 1.8 mm by 1.39 times, 2.0 mm — by 3.5 times, and 2.3 mm — by 1.79 times. Conclusion. Use of autologous modification technology of dental implants made of non-woven titanium material optimizes stability values of dental implants.
