Clinical research of autogenous chin bone graft and secondary implantation in repairing the bone deficiency of anterior maxilla
摘要
Abstract
Objective: To demonstrate the clinical effectiveness of ridge augmentation by using autogenous chin graft for the lack of bone mass of the anterior maxilla, following by secondary ITI implantation. Methods: From July 2009 to May 2012, 21 patients with severe alveolar ridge resorption in anterior maxilla were included in this survey. The patients` age ranged from 18 to 42 with an average age of 27.7 years old. 14 out of the 21 patients presented with missing single tooth while the rest of 7 lost multiple teeth. A total of 28 implants were embedded. Bone grafts harvested from mandible chin were used for augmentation. Results:After 4.5 to 10.0 months healing period (mean 6.3 months), 21 patients underwent dental implants placement, 3 to 9 months later(mean 5.2 months)these implants were all re-stored with ceramic crowns/bridges. Flap dehiscence was observed in one case, which is recovered by mucosa after local treatment; 3 patients were observed with postoperative lower lip hypoesthesia, 1 of them combined with changed pulp sensitivity of the mandibular anterior teeth. After the use of mecobalamin, all lower lip hypoesthesia disappeared, while the mandibular anterior teeth's clinical symptoms improved. The follow-up period was 12 month to 30 month (mean 17.3 months). The survival rate of all 28 implants was 100%. Conclusions: By using autogenous block grafts from chin to improve the lack of bone mass in anterior maxilla, the results of ITI implants restore the loss of upper anterior teeth can be satisfied.关键词
