Evaluation of the osseointegration of dental implants coated with calcium carbonate: an animal study

Abstract

Coating titanium implants with calcium carbonate (CC) may improve their integration with the surrounding bone tissue. Yining Wang of China’s Wuhan University and colleagues tested a new method to prepare CC coatings for titanium implants. CC is resorbable, that is, it is absorbed by the body after a period of time. Current implants coated with non-resorbable materials show decreasing success rates several years after implantation. CC-coated and control implants were embedded in the legs of rabbits and extracted one, two, four, eight and 12 weeks after surgery. The CC-coated implants integrated earlier with the surrounding bone tissue than the controls. The method needs improvement due to incomplete coating of the titanium surface but the team believes CC-coating of titanium implants could reduce healing times and lead to higher implant success rates.
