Comparative Histological and Histomorphometric Results of Six Biomaterials Used in Two-stage Maxillary Sinus Augmentation Model After 6-month-healing
Objectives: The aim of the study was to compare histological and histomorphometric results of six bone substitute materials used as graft in two-stage maxillary sinus augmentation model, after 6-month-healing.
Materials and Methods:
A two-stage sinus augmentation was carried out in six patients using mineralized solvent-dehydrated bone allograft (MCBA), freeze-dried mineralized bone allograft (FDBA), anor-ganic bovine bone (ABB), equine-derived bone (EB); synthetic micromacroporous biphasic calcium-phosphate block consisting of 70% beta-tricalcium phosphate and 30% hydroxyap-atite (HA-β-TCP 30/70), or bioapatite-collagen (BC).
Inclusion Criteria: patients healthy, absence of systemic pathologies (ASA class I), non-smokers, good oral hygiene, not pregnant or lactating, absence of painful symptoms and associated inflammatory or osteolytic pathologies, maxillary partial edentulism involving the premolar/molar areas, residual bone height between the sinus floor and alveolar ridge ranging from 2 to 4 mm, as measured on computerized tomography (CT) scan.
