Histomorphometric evaluation of mineralized cancellous allograft in the maxillary sinus augmentation: a 4 case report.
OBJECTIVE
The aim of this article is to report the histomorphometric analysis and clinical study of mineralized cancellous bone allografts in maxillary sinus augmentation procedures in 4 cases.


METHODS
Sinus bone augmentation, using a piezoelectric device and mineralized cancellous allografts, was performed in 3 patients. After an average of about 8 months of healing, a trephine core sample was gained from the lateral windows area for histomorphometric analysis. The mineralized cancellous allografts demonstrated normal healing of hard tissues.


RESULTS
Upon reentry for dental implant placement or secondary surgery, the graft materials showed hard bony structures within the maxillary sinus. Histomorphometric analysis of the cores revealed an average vital new bone content of 17.88%.


CONCLUSIONS
Mineralized cancellous allografts showed favorable bone regeneration histologically and was clinically useful in augmenting bone volume for implant placement in the sinus bone graft.
