[A histologic observation of bone formation induced by subperiosteal implantation of resorbable porous block beta-tricalcium phosphate on calvarial surface in rabbits].
OBJECTIVE
By the histologic observation of samples, understanding the osteoconductive histologic behaviour and resorbable mechanism of beta-tricalcium phosphate (beta-TCP).


METHODS
Porous block beta-TCP samples were implanted into calvarial surface. Tissue slices dyed with methods of HE and Masson's were observed by microscope and compared with hydroxyapatite(HA).


RESULTS
Beta-TCP had the osteoconductivity,as well as HA, plentiful new bone penetrated into materials from the calvarial surface. There was no new bone under the periost obviously. A large number of rhagiorine cells swallowing beta-TCP had been observed.


CONCLUSIONS
Beta-TCP has osteoconductivity, can be used as a substitution for atrophic alveolar ridge augmentation. The function of rhagiorine cell swallowing beta-TCP is the essential resorbable mechanism of beta-TCP.
