Abstract

This study was aimed to suggest to better treatment method of jaw cyst that the maximum diameter was wider than 3 cm, using different treatment and clinical and radiographic result. We divided the 60 patients into three groups, group A(20 patients) were treated with cyst enucleation and Decalcified Freeze-Dried Allogeneic Bone(DFDB) graft, group B(20 patients) were treated with cyst enucleation and autogenous bone graft, group C(20 patients) were treated with only cyst enuclation. Each group was evaluated with panoramic radiograph and clinical sign & symptom at pre-op and post-op(immediate, 6, 12, 24, 36 month). Bone density was evaluated with disital densitometer. The result was as follows : 1. Post-Op infection was higher in group C(4 Pts.) than in group A(1 Pt.) and B(1 Pt.) 2. Post-Op gingival recession was higher in group C(3 Pts.) than in group A(1 Pt.) and B(1 Pt.) 3. Anatomic distortion was higher in group C(3 Pt.) than in group A(1 Pt.), and B(1 Pt.) 4. Reoperation was done in two patients who were in group C 5. There were donor site morbidity in two patients 6. There was no significant difference between group A and B in their bony density in their follow up period(p>0.05). 7. There were significant differences between group A, B and group C in their bony density until post-op 24 months but a little differences at post-op 36 months(P<0.01)
