    Abstract

    Purpose

    The aim of this report is to investigate the efficacy of anorganic bovine bone xenograft(Bio-Oss®) at maxillary sinus floor augmentation.

    Materials and methods

    Two male patients who missed maxillary posterior teeth were included. They were performed maxillary sinus floor augmentation using anorganic bovine bone xenograft(Bio-Oss®). 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® 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® 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®) has high osteoconductivity and helps new bone formation, so that it can be used in maxillary sinus floor augmentation.
