Use of infrared thermography to control osteoreparative and integrative processes during implantation in animals

Abstract

Thermography is an integral indicator which is formed by means such factors as the vasculature and the level of tissue metabolism. Infrared thermal imaging can be a tool for assessing the safety and effectiveness of implantation in bone tissue using various materials. The aim of the study was a comprehensive assessment of osteoreparative and integrative processes using thermography when implantation in dogs. The research objects were clinically healthy outbred dogs (n=16) at the age of 1 year and a live weight of 10-12 kg. Experimental implants coated with titanium dioxide had on their surface a polymer film of polyazolidinammonium modified with halogen hydrate ions with nanoaggregates of flavonoids according to the original author's technique (Patent No. 2535067). Similar implants without coating were used as a control. According to the results of x-ray studies in the early and longterm after surgery, there were no foci of bone resorption in the peri-implant zone. Thermography showed a difference in temperature values in the peri-impalantant zone of experimental and control samples reaching 2°C during 1-4 weeks after implantation. On day 32, the temperature indicators for control and experimental samples were stabilized. Consequently, osteoreparative and integrative processes when using implants with author's coating are accompanied by significantly less metabolic stress for the animal's body, which was established using infrared thermography.
