Evaluation of the effect of synthetic biomaterial (calcium phosphate ceramic)‎ on healing of extracted tooth socket

الملخص EN

Back ground : There are very few data about the effect of calcium phosphate ceramic on the healing of tooth extracted sockets after tooth extraction and it still controversial.

The aim of the study was to evaluate the clinical applicability and histological behavior of newly developed phosphate ceramic as a bone filler for dental socket after tooth extraction.

Materials and methods : Twenty four rabbits were used for extraction of upper central incisor under general anesthesia.

The left side filled with phosphate ceramic material, and the right side lifted for normal healing as a control group.

The two sockets were sutured.

The results were studied radiographically and histologically after 1, 2, 4, 6 weeks postoperatively.

The radiographic examination was performed also immediately after operation by using parallel technique in a digital radiographic examination and histological examination was performed under light microscope for the section stained with heamatoxiline and eosin to assist histometric analysis including counting of bone cells and trabecule thickness, at the end of each four periods interval post operatively.

Results : Radiographical examination showed that phosphate ceramic materials reduced vertical resorption of alveolar ridge after tooth extraction.

Histological examination showed the acceleration of bone formation in the socket more than bone destruction within first few weeks after tooth extraction that prevent alveolar ridge resorption.

Conclusion : This study was illustrated that phosphate ceramic material was osteinductive material that enhances the osteogenisis process in the extracted tooth socket more than normal physiological healing process.
