SINUS GRAFT AND VERTICAL AUGMENTATION OF MAXILLARY POSTERIOR ALVEOLAR RIDGE USING MANDIBULAR RAMAL BLOCK BONE GRAFT

Abstract

The maxillary posterior area is the most challenging site for the dental implant. After missing of teeth on maxillary posterior area due to periodontal problems, the remaining alveolar ridge is usually very thin because of not only pneumatization of maxillary sinus but also destruction of alveolar bone. The maxillary sinus bone graft procedure is one of the most predictable and successful treatments for the rehabilitation of atrophic and pneumatized endentulous posterior maxilla. But, in case of severe destruction of alveolar bone due to periodontal problems, very long crown length is still remaining problem after successful sinus graft procedures. We performed vertical augmentation of maxillary posterior alveolar ridge using mandibular ramal block bone graft with simultaneous sinus graft. After this procedures, we could get more favorable crown-implant ratio of final prosthodontic appliance and more satisfactory results on biomechanics. This is a preliminary report of the vertical augmentation of maxillary posterior alveolar ridge using mandibular ramal block bone graft with simultaneous sinus graft, so requires more long-term follow up and further studies.
