Abstract:
This report details the implant rehabilitation of a patient with extensive maxillary bone loss secondary to chronic odontogenic sinusitis. Prolonged inflammation rendered the right posterior maxilla unsuitable for spontaneous regeneration, necessitating a staged multidisciplinary intervention. Treatment commenced with sinus management via incision and drainage and a targeted pharmacological regimen. Once clinical resolution was achieved, reconstruction was performed using an autogenous bone block harvested from the right mandibular ramus combined with xenogenic substitutes. A key aspect of the surgical procedure was the utilization of a press-fit fixation technique, where the ramal block was precisely contoured to achieve immediate mechanical stability and screwless fixation through frictional force and mechanical interlocking. The approach was divided into four phases: (1) management of sinusitis; (2) sinus floor elevation and reconstruction using a press-fit autogenous ramal block; (3) implant placement (#16, #17) after a five-month graft maturation period; and (4) final prosthesis delivery after a three-month osseointegration period. The successful outcome demonstrates that predictable functional restoration can be achieved through a planned staged protocol integrating medical management and press-fit bone grafting, even in severe bone deficiency complicated by sinus pathology.
