Abstract:

Objective To explore the effect of anterior alveolar bone reconstruction achieved through autogenous block bone from the wisdom teeth extraction zone in onlay grafting technique. Methods The 20 patients with bone defect of anterior teeth area were selected. They all had impacted teeth with no infection factors of pericoronitis to be removed. They were treated with autogenous block bone grafts from wisdom teeth extraction zone in onlay grafting technique respectively. The changes of thickness and the height of the bone measured from CBCT before and after 6 months of the surgery were carefully compared. Questionnaire from the patients opinion of acceptance was also be collected. Results Acceptance questionnaire showed an average score of 55 points (60 full score). Among them, 75% of paitients showed totally supportion and 25% showed basically supportion. The thickness was 6.73 ± 0.28 mm after the surgery compared with 2.26 ± 0.57 mm before the surgery which illustrated a significant difference (F = 6.32, P<0.001). The height didn't change obviously before 14.32 ± 0.31 mm and after 14.56 ± 0.35 mm the surgery. The technique of using autogenous block bone from the wisdom teeth extraction zone improved the compliance of patients with surgery. It can provide good osteogenesis effect and solve other oral diseases at the same time. Conclusion The Onlay grafting technique which using autogenous block bone from the wisdom teeth extraction zone was a simple and effective techniques for anterior alveolar bone augmentation.
