Indirect maxillary sinus lift using summer’s osteotome technique and immediate implant placement with 2-years follow-up: A case report

The restoration of the posterior edentulous maxilla with dental implants is constantly challenging to the restorative dentist. This is due to the maxillary sinus pneumatization and expansion as a result of the increased osteoclastic activity of the Schneiderian membrane periosteum after tooth extraction, with consequent reduction in bone height or volume, in addition to the lower quality of maxillary bone, when compared to the mandible. This results in insufficient bone for implant osseointegration and primary stability impeding implant placement. Maxillary sinus lift with or without bone graft aims to provide sufficient bone volume, providing the supplementary anchorage and stability mandatory for successful implant osseointegration. This maybe done directly through lateral wall of the sinus which is more invasive, or indirectly through the alveolar bone crest, which is comparatively less invasive. Therefore, the preferred treatment is the minimally invasive indirect sinus lift technique when feasible. The objective of this case report is to demonstrate indirect maxillary sinus lift procedure with immediate implant placement, without bone-graft using minimally invasive Summers’ osteotome technique preventing maxillary sinus membrane perforation.
