The Evaluation of Calcium Phosphate Coated Implants by Ion-beam Assisted Deposition (IBAD) Method in Dogs : A Preliminary Study
- 0
Rough surfaced implants have been reported to favor early bone healing than smooth surfaced implants. Amongvarious methods introduced to roughen the implant surface, coating with calcium phosphate(CaP) is one of them. The purpose of this study was to evaluate the bone healing response of anodized implants with two different coatingthickness of CaP(200 nm and 500 nm) deposited by ion beam assisted method. CaP coated implants wereplaced on circumferencial coronal defects of four mongrel dogs and the amount of defect fill was evaluated histologicallyafter 8 weeks. The amount of coronal defect filling varied among the implants according to its surface characteristics. The CaP coating thickness of 500 nm showed the greatest amount of defect fill than implants with200 nm of CaP coating thickness and non coated implants. Within the limits of this study, when coating implantswith CaP by ion-beam assisted deposition method, coating thickness of 500 nm seemed to be effective.
