[Effect evaluation of medical calcium sulfate--OsteoSet in repairing jaw bone defect].

AbstractOBJECTIVE:
To investigate the effectiveness of the medical calcium sulfate-OsteoSet bone graft substitute in the treatment of defect after excision of jaw cyst.
METHODS:
Between December 2009 and May 2010, 15 cases of jaw cystic lesion were treated, including 9 males and 6 females with an average age of 36.6 years (range, 15-75 years). Orthopantomography (OPT) method was used to measure the cyst size before operation, and the size ranged from 1.5 cm x 1.5 cm to 8.0 cm x 3.0 cm. The range of bone defect was from 1.5 cm x 1.5 cm x 1.5 cm to 8.0 cm x 3.0 cm x 3.0 cm after cyst excision intraoperatively. The patients underwent cyst curettage and OsteoSet bone graft substitutes implantation (2-15 mL). Radiological method was used to evaluate the repair effect of OsteoSet pellets.
RESULTS:
The pathology biopsy was periapical cyst in 7 cases, odontogenic keratocyst in 5 cases, and dentigerous cyst in 3 cases. Fifteen patients were followed up 6-12 months. Thirteen patients achieved wound healing by first intention; 2 cases had longer drainage time (5 and 7 days, respectively), the incision healed after the pressure bandage. Swelling occurred in 1 case after 1 month with no symptom of infection. No postoperative infection and rejection was found. The X-ray examination showed that the materials filled the bone defect well after 1 day of operation. OsteoSet bone graft substitutes were absorbed by one-half after 1 month of operation and totally after 3 months by OPT. The low density area was smaller in the original cysts cavity, and high density in the cysts increased significantly with fuzzy boundaries of cysts. At 6 months after operation, there was no obvious difference in image density between the original cavity and normal bone, and the capsule cavity boundary disappeared, and defect area was full of new bone.
CONCLUSION:
The medical calcium sulfate-OsteoSet bone graft substitute is an ideal filling material for bone defect.
