Instrumentation for placement of vitreous carbon endosseous implants.

The instruments required for placement, stabilization, and restoration of vitreous carbon endosseous implants are conventional in character and readily available. With the exception of extra-long burs for socket preparation, all instruments are normally available in dental offices. The surgery instruments should be rigorously sterilized prior to use, including the dental handpiece, burs, suction tip, etc. Gas sterilization techniques provide an effective means of sterilizing the surgical instruments without causing corrosion of burs and the handpiece.

Histologic evaluation of vitreous carbon endosteal implants in dogs.

A 6-month histologic study of vitreous carbon dental implants in dogs, without occlusion, has demonstrated that vitreous carbon is well tolerated by oral tissues in both permucosal and subgingival applications. Gingival tissues heal routinely and show the same degrees of irritation adjacent to the implant as tissues adjacent to natural teeth. Alveolar bone forms within grooves in the implant surface, providing mechanical retention, and both hard and soft tissues grow into the texture in the implant surface. The resulting interlocking between tissues and the implant appears to function effectively as a bacterial seal. The newly formed bone within the implant grooves appears to become more dense with time, resulting in a layer of dense bone surrounding the implant. No foreign body responses and no inflammation were observed in tissues adjacent to this implant material, and no degradation of the vitreous carbon implants was detected. A subsequent study of the implant under occlusion in dogs is also being conducted.

Histologic evaluation of vitreous carbon endosteal implants in occlusion in dogs.

A 6-7 month histologic study of vitreous carbon endosteal implants in occlusion was conducted in dogs to determine whether the shape of the implant has adverse effects on supporting tissues. Conical vitreous carbon implants were placed in fresh, second, and third premolar extraction sites, and the sites were allowed to heal for periods of 2 to 8 weeks prior to restoration with cast gold crowns. Gingival tissues healed routinely and showed inflammatory conditions similar to tissues adjacent to teeth, and normal sulculur depths were measured. Bone formation was observed within grooves in the implant surface, providing retention and stabilization, normal bone remodeling appeared to be occurring adjacent to the implant sites. No inflammatory responses, foreign body reactions, or infections were observed. Vitreous carbon appears well suited for application as an endosteal implant material.
