Pre-prosthetic schuchardt osteotomy with sinus floor elevation.

Premature loss of teeth leads to an inevitable egression of opposing teeth. Schuchardt osteotomy is a quick and efficient alternative to create a prosthetic space compatible with prosthetic rehabilitation. During the surgical procedure, it is difficult, if not impossible, to preserve the integrity of the sinus membrane and thus to proceed at the same time with a bone graft in the adjacent sub-sinus area to address a vertical alveolar deficiency. In this technical note, the author describes a new technique by combining a sinus suspension during a Schuchardt osteotomy. This innovative approach allows for the treatment of Schneider's membrane perforation and the simultaneous achievement of sub-sinus bone augmentation during the osteotomy.
