Acceleration of bone healing : A myth or reality ?
Objectives: -Evaluate radiographically using cone beam computed tomography the bone quantity after sinus augmentation by the combination of hyaluronic acid and xenograft.
-Evaluate by histomorphometric analysis the bone quantity and quality after sinus augmentation by the combination of hyaluronic acid and xenograft.
Methods: The present study were conducted on patients who were requiring maxillary sinus augmentation .Twenty maxillary sinuses were randomly allocated into one of the two groups "A &B".
Group A: ten sinuses received xenograft as a control group.
Group B: ten sinuses were augmented by xenograft mixed with hyaluronic acid as a test group.
-Bone quantity was assessed using CBCT at pre-surgery and 6 month post-operative.
-Core biopsy specimen were obtained from all patients 6 month post-operative and histomorphometric analysis were done .
Results: -There was no statistically significant difference in the bone height gain radiographically between the two groups.
-There was statistically significant difference in the bone height gain radiographically within each group.
-Histomorphometric results showed that newly formed bone was statistically significant in the study group.
Conclusions: Enhancement of bone healing by hyaluronic acid could lower the time needed for implant placement and rehabilitation.
