ABSTRACT
PURPOSE:
The aim of this report is to investigate the efficacy of anorganic bovine bone xenograft(Bio-Oss(R) ) at maxillary sinus floor augmentation. MATERIALS ANDMETHODS:
Two male patients who missed maxillary posterior teeth were included. They were performed maxillary sinus floor augmentation using anorganic bovine bone xenograft(Bio-Oss(R) ). After 10 or 13 months, the regenerated tissues were harvested using trephine drills with 2 or 4mm diameter and non-decalcified specimens were made. The specimens were examined histologically and histomorphometrically to investigate graft resorption and new bone formation.RESULTS:
Newly formed bone was in contact with Bio-Oss(R) particles directly without any gap between the bone and the particles. The proportions of newly formed bone were 23.4~25.3% in patient 1(Pt.1) and 28.8% in patient 2(Pt.2). And the proportions of remained Bio-Oss(R) were 29.7~30.2% in Pt.1 and 29.2% in Pt.2. The fixtures installed at augmented area showed good stability and the augmented bone height was maintained well.CONCLUSION:
Anorganic bovine bone xenograft(Bio-Oss(R) ) has high osteoconductivity and helps new bone formation, so that it can be used in maxillary sinus floor augmentation.
