Histomorphometric Evaluation of a Calcium-Phosphosilicate Putty Bone Substitute in Extraction Sockets
Kotsakis, Georgios A. / Joachim, Frédéric P. C. / Saroff, Stephen A. / Mahesh, Lanka / Prasad, Hari / Rohrer, Michael D.
The objective of this study was to evaluate bone regeneration in 24 sockets grafted with a calcium phosphosilicate putty alloplastic bone substitute. A core was obtained from 17 sockets prior to implant placement for histomorphometry at 5 to 6 months postextraction. Radiographic analysis during the same postextraction healing period showed radiopaque tissue in all sockets. Histomorphometric analysis revealed a mean vital bone content of 31.76% (± 14.20%) and residual graft content of 11.47% (± 8.99%) after a mean healing period of 5.7 months. The high percentage of vital bone in the healed sites in combination with its timely absorption rate suggest that calcium phosphosilicate putty can be a reliable choice for osseous regeneration in extraction sockets.
