Hydroxylapatite and tricalcium phosphate implants in the dental alveolus of rats. A histometric study.
The objective of the present study was to analyze histomorphometrically the biological behavior of microgranular hydroxylapatite (HA 40), and tricalcium phosphate (TCP) implanted in the dental alveolus of rats. All three materials retarded alveolar repair when compared to controls, since less bone was formed during all periods of study. Nevertheless, MIC and TCP showed higher compatibility than HA 40.
