An in vivo comparative evaluation of graft uptake between chin and ramal graft in the reconstruction of atrophic anterior maxillary edentulous ridges for implant placement

Abstract

Introduction: The goal of modern dentistry is to restore the patient to normal function, esthetics, comfort, speech and health, which can be brought by caries prevention or replacing of missing teeth. Loss of teeth may be devastating for the patient, both functionally and aesthetically. Complex anatomy, functional and aesthetic demands often make reconstruction very challenging as well as the multitude of complications that can arise during or after treatment. Aim and Objectives: To evaluate the amount of bone resorption of mandibular autogenous block bone graft in reconstruction of atrophic anterior alveolar ridges. Materials and Methods: 5 patients underwent harvesting of corticocancellous bone from Mandibular ramus and 5 patients underwent harvesting of corticocancellous bone from Mandibular chin region for Reconstruction of atrophic alveolar ridge. All patients were reviewed for follow-up for 5 months to evaluate the amount of resorption and acceptance of graft. Results: In a follow up period of 5 months the mean graft resorption in ramal graft is 16.8% and mean graft resorption in symphysis graft is 18%. Conclusion: Minimally invasive approach, ease of application, volume of the graft and least postoperative morbidity are observed in ramal graft. The survival of the graft is better in ramal graft than the graft from the chin as the chin graft shows higher resorption rate. Patient compliance is favorable more towards the ramal graft than the chin graft as the immediate postoperative pain is high in symphysis region.
