Abstract
Objective: To evaluate the clinical effects of application of the piezosurgery device in root separation and tooth hemisection combined with dowel crown or fixed bridge.Methods: Totally 27 mandibular molars agreed with the criteria we set were selected.Root separation,tooth hemisection,crown lengthening and furcation involvement therapy when needed were performed with piezosurgery device after consummate root canal therapy.Then post and core were restored and combined crowns or bridges were made.All the cases were followed up for 2 years.Results: All of the teeth functioned well except one failed in progress of periodontitis.X-ray shows no obvious alveolar bone loss.Conclusion: A satisfactory treatment effects could be achieved by using the piezosurgery device in root separation and tooth hemisection combined with dowel crown or fixed bridge to save mandibular molars with severe defect.
