- Abstract
Objective: To evaluate the clinical effectiveness of tooth-alveolar bone grafts in repairing dentition defects., Methods: Forty-five patients with dentition defect were divided into two groups according to different operation methods. In group A (n=24), the tooth-alveolar bone grafts of the transplanted tooth and its surrounding alveolar bone were cut using modified surgical orthodontics and then embedded into the designated planting hole. In group B (n=21), the teeth were extracted through conventional tooth transplantation and then embedded into the prepared planting holes. The transplanted teeth were fixed for about 4-6 weeks using the orthodontic method. During the postoperation, which lasted for 2-12 weeks, root canal treatments were administered selectively. The medical effect was regularly followed up and evaluated., Results: No significant difference was found in the change of color and the periodontal ligament image between the two groups (P>0.05) whereas significant differences were observed in the degree of tooth mobility, the absorption of root and alveolar bone, and the rate of root canal treatment (P<0.05). The curative effect in group A was superior to group B., Conclusions: Tooth-alveolar bone graft transplantation has overcome some of the limitations of traditional tooth transplantation. Therefore, it is an effective means of repairing dentition defect.
