TITANIUM IMPLANT INSERTION INTO DOG ALVEOLAR RIDGES AUGMENTED BY ALLOGENIC MATERIAL

The purpose of this investigation was to evaluate whether titanium end osseous implants would osseointegrate in dog alveolar ridges augmented by allogenic material. In 8 dogs en bloc resection, including 2 pre-m olars, was performed bilaterally in the maxilla and the mandible. Afte r a healing period of 6 weeks allogenic, demineralized and lyophilized dentin or bone was implanted subperiosteally. Titanium implants were installed 5.5 months later in some of the regions. Light and fluoresce nce microscopic evaluation revealed fibrous encapsulation of the impla nted allogenic material, no osteoinduction and only minimal osteocondu ction, few multinuclear giant cells and a sparse inflammatory reaction . The titanium implants healed mainly by fibrous encapsulation.
