| Popis: | Highlights • This case report is the first in literature to use Bio-oss in segmental maxillary. • 3D planning showed us a favorable bone structure to use a granular biomaterial graft. • Follow-up with CT images showed that the decision was correct. Introduction Segmental maxillary osteotomy enables correction of anterior open bites. However, the outcome can be somewhat unstable, particularly if pseudarthrosis occurs. Bone grafts can be used to prevent this complication. Among the many biomaterials available for grafting, Bio-oss® has been used successfully in a range of modalities, with studies to support several indications. This report describes a case of segmental maxillary osteotomy in which Bio-oss® granules were used as bone grafts in the surgical gap. Presentation of case A 24-year-old female presented with anterior open bite, Angle class III posterior occlusion, and Angle class II anterior occlusion. Virtual surgical planning of the procedure predicted a gap of approximately 5 mm in the region of the osteotomy, which was bridged with Bio-oss® granules. Discussion Although autogenous bone grafting is the gold standard due to its osteoconductive, osteoinductive, and osteogenic properties, it involves increased morbidity for the patient, unpredictable resorption rates, increased operative time, and risk of infection at the donor site. Use of the Bio-oss® material can provide good bone stability, osteoconduction, and biocompatibility, while reducing operative time and surgical morbidity. Conclusion This is the first report of bone grafting with a granular biomaterial in segmental maxillary osteotomy. Successful formation of new bone with density greater than that of the surrounding tissue was achieved, preventing pseudarthrosis and postoperative instability. |
