The use of oral fluid to diagnose problems of dental implant osseointegration

The study presents the results of defining some physico-chemical properties (viscosity and sliding friction coefficient) and four biochemical indices of oral fluid in 146 patients after installation of fixed dentures relying on intraosseous implants. On the basis of clinical examination, the prosthetic patients were divided in two clinical groups with different risk of poor or uncompleted adaptation to fixed dentures. Forty-eight peoples being practical health, made up a comparison group. As a result, we conclude, that the inclusion of used methods in the diagnostic complex to control osseointegration and adaptation of prosthetic patients allows more accurate predict the risk of late complications after dental implantation. These changes are in correlation with the classical signs of inflammatory processes in peri-implant tissues in the X-ray examination, including determination of bone density around implants.
