Rehabilitation of Maxillary Posterior Edentulism with Direct Antroplasty and Dental Implants: A comparative analysis of two different types of bone grafts

Abstract

Aims - To determine the difference in the amount of bone generated from two different sites for bilateral maxillary sinus augmentation. Introduction-Rehabilitation of the edentulous posterior maxilla with an implant supported prosthesis is a commonly occurring challenge in dental practice. Objectives - Achieving adequate height of alveolar bone for placing dental implants requires uplifting of the sinus lining in many such cases. This is generally done by harvesting bone grafts from various sites and placing it in the defect created after raising the sinus lining thus restoring the height and width of residual alveolar bone. Objectives - To determine if regional sites of bone graft harvest are equally effective when compared with distant site. Material & Methods - In this series, out of 3 of our patients, two received autologous chin grafts and one patient received PCBM graft from the iliac crest. In all 3 patients, implants were placed in the second stage. Results -Acomparative analysis of the feasibility of the two techniques which involves bone grafts from two sites which have different quality of bone available over the end outcome was done and it was found that the quality of bone available for implant placement was almost the same irrespective of the graft harvest site. Conclusion - It can be safely concluded chin graft is a viable alternative to cortico-cancellous bone graft in cases of direct sinus lift procedures with minimal issues of donor site morbidity.
