Treatment of cystic lesion of mandible using combination of modified bone granules and calcium phosphate bone cement: A preliminary report.

AIMS: This study was conducted to evaluate healing of bony cavity in mandible following enucleation of cystic lesion by obliterating the cavity using modified natural bone granules (G Graft) and calcium phosphate bone cement (G Bone).

MATERIALS AND METHOD: In this technique, after enucleation of cystic lesion, peripheral ostectomy using No. 702 fissure bur and perforation of the inferior cortex using 1.5 mm drill bits were performed. Modified hydroxyapatite granules were used to fill the defect while calcium hydroxide bone cement was used to seal the cavity opening. Thirty-seven patients were treated using this technique. In 30 patients, quality and quantity of bone were within acceptable limits, and in 7 patients, there was extrusion of graft material and post-operative infection.

CONCLUSION: Treatment of cystic lesion of mandible using combination of modified bone granules and calcium phosphate cement is good alternative to other treatment methods. Long-term and comparative studies are required to evaluate its advantage over the other methods of treatment.
