[Comparative study of two different types of dental implants in dogs. Experimental study].

Abstract

Mandibular incisors were taken out in 13 adult dogs. Twenty days after the extraction, two implants either of titanium or hydroxylapatite were placed in a second operation. The clinical, pathological and radiological results suggest that metallic implants produce fibrous tissue around the implant. In most cases, fibrous tissue does not ossify and this facilitates the formation of a malunion and the mobilization of the implant. However, the results with hydroxylapatite implants appear to be satisfactory due to the formation of an osseous tissue mandibular bone. This tissue prevents the mobilization of the implant allowing support to a dental prostheses.
