The clinical images of rabbit and dog implantation procedures. A) In the rabbit animal model, coin shaped implants were placed onto the cortical bone of tibia without mechanical fixation to the bone. Therefore, the implant was retained inactively on bone by a titanium band retainer. After implantation, the contact between the implants and bone was limited to the flat test surfaces. Additionally, a polytetrafluoroethylene (PTFE) cap was used for covering the vertical and the upper faces of implants to hinder interlocking effects from lateral bone attachments. B) Clinical images of dental bone chamber implants in dog animals. Three bone chamber implants were placed per quadrant (six implants per animal jaw). In this study, we used bone chamber implants because the bone formation around this type of implant is only new bone; however, in clinical implants it is a combination of new and old bone formation.
