We have utilized many kinds of titanium blade implants for over nineteen years. It is recently considered that osseointegration is superior to fibrointegration. So, various types of H.A.-coated blade implants have been developed.
Any blade implants must be connected to natural teeth. So, there seems to be the possibility that the concentration of stress is caused in the complex of the superstructure, supporting teeth and the implant that is connected directly to the bone without fiberous tissue. We have experienced some troubles that might be caused by it. Therefore, we concluded that we must be careful due to the design of the superstructure when connecting natural teeth and osseointegration type implant.
