[Histological study of the dental implant-bone interface remodeling of submerged and nonsubmerged implants in dogs].
OBJECTIVE
To compare the characteristics of histological reaction at the implant-bone interface after submerged and nonsubmerged implant remodeling in dogs.


METHODS
Eight adult mongrel dogs were used to establish the animal model for submerged and nonsubmerged implants into the bilateral mandibular sites. At 1, 2, 4, and 12 weeks postoperatively, 2 dogs were sacrificed at each time point for histological observation of the healing and remodeling process at the implant-bone interface by HE staining.


RESULTS
No distinct difference in the rate of new bone generation and degree of osseointegration was observed between dogs with submerged and nonsubmerged implant at each time point.


CONCLUSIONS
In spite of the bite force imposed on the abutment to some extent during the healing process after nonsubmerged implant plantation, favorable osseointegration similar to that after submerged implants can be achieved.
