Background: Tooth extraction commonly leads to loss of residual alveolar ridge, thus compromising the room available for the implant placement. To combat the post-extraction alveolar loss, alveolar ridge preservation is practiced, with the advent of the biomaterial available. The purpose of this study was to assess the efficiency of calcium phosphosilicate biomaterial in alveolar ridge preservation. Twenty patients indicated for extraction were selected followed by socket grafting using calcium phosphosilicate. Implant placement was done 6?months postoperatively during which a core was harvested from the preserved sockets. Clinico-radiographic measurements of hard and soft tissues were taken at baseline and 6?months post-grafting.

Results: There were no significant changes in the radiographic and soft tissue parameters while significant changes in hard tissue parameters with 1.9?mm (p?=?0.013) gain in mid-buccal aspect and 1.1?mm (p?=?0.019) loss in horizontal bone width were observed. The histomorphometric evaluation depicted the vital bone volume of 54.5?±?16.76%, non-mineralized tissue 43.50?±?15.80%, and residual material 2.00?±?3.37%.

Conclusion: The implants placed in these preserved ridges presented 100% success rate with acceptable stability after a 1-year follow-up, concluding calcium phosphosilicate is a predictable biomaterial in alveolar ridge preservation.
