ABSTRACT
A procedure using osteotomes and bioactive glass as an alloplastic bone graft material is discussed, and three clinical cases are reviewed. Bioactive glass of a narrow size range (300-355 microns) has been shown to be osteoconductive and allows for good integration and regeneration of surrounding bony tissue. We have found this technique to be a predictable method of preparing and placing longer implants in the region of the maxillary premolar region without the need for additional donor site morbidity.

A granular cell tumor occurred in the right anterior maxilla of a 22-yr-old black man. It involved the right labial maxillary submucosa and the underlying bone. It also invaded the maxillary sinus and the nasal cavity on the same side. The ultrastructural features of the lesion confirmed the biopsy diagnosis of benign granular cell tumor. The treatment involved partial maxillectomy, split thickness skin graft and immediate dental prosthesis.
