Sinus Lift
A surgical bone-augmentation procedure that elevates the Schneiderian membrane of the maxillary sinus to create space for bone graft material in the posterior maxilla.
Full Definition
Also known as sinus floor augmentation or maxillary sinus augmentation, a sinus lift is performed when insufficient vertical bone height in the posterior maxilla precludes standard implant placement. Two main techniques are recognized: the lateral window (Caldwell-Luc) approach and the transcrestal (osteotome) approach, the latter often referred to as an 'internal sinus lift.' Editors should use 'sinus lift' or 'sinus floor augmentation' consistently within a document, noting that 'sinus elevation' is an acceptable synonym. The term is always two words and not hyphenated as a noun.
Usage
Usage note: Two words, no hyphen as a noun ('sinus lift'). Specify technique (lateral vs. transcrestal) for clinical precision.
