Tooth morbidity and tooth mortality are one of the most prevalent disease condition worldwide.When a tooth is lost, whether through dental decay, periodontal disease or dental trauma, the alveolar process begins to remodel. Continuous bone remodeling, absence of stimulation, loss of bone height, and density leads to an increase in antral pneumatization , leading to reduction in residual vertical bone height thus making standard implant placement difficult. To adapt, circumvent, and treat this limitation; maxillary sinus floor elevation is often done and has become an important preplacement procedure in dental implant treatment planning. In this article, we present a unique case of maxillary sinus augmentation of right posterior maxilla using a combination of autogenous chin block graft, and allograft with simultaneous placement of endosseous implants.
