Summary

The decrease in maxillary alveolar ridge bone volume and sinus pneumatization are a challenge to implant-assisted prosthetic rehabilitation. Guided bone regeneration using bone substitutes is an adequate alternative for maxillary sinus augmentation. Objective: To histologically and histomorphometrically compare bone repair response to 250 to 1000 µm and 1000 to 2000 µm anorganic bovine bone mineral (ABBM) particles as bone substitute in maxillary sinus augmentation (MSA).

Detailed description

Twenty patients were treated with SMA in two steps. They were randomly assigned to one of two groups (n=10): SPG (small particles group) and LPG (large particles group). Different size ABBM particles were implanted in their maxillary sinus, accordingly. A vertical bone core biopsy was obtained at the implant site using a punch trephine. The samples were processed for histological observation and measured histomorphometrically to determine the percentage onewly formed bone (%NB), bone substitute (%BS), bone marrow (%BM), and osseointegration (%OI). Results were statistically analyzed using Student's t test (p ≤ 0.05).
