Osteotome sinus floor elevation and simultaneous, non-submerged implant placement: case report and literature review.

The osteotome sinus floor elevation is a conservative technique for sinus elevation and immediate implant placement. The purpose of this report is to present a case using the sinus floor elevation technique for placement of a non-submerged implant with 12 months follow-up after permanent restoration and to review the literature regarding sinus floor elevation. The osteotome sinus floor elevation technique may be used successfully for the placement of nonsubmerged implants. It allows for shorter post-treatment waiting times and provides a less invasive approach compared to 1- or 2-step antrostomy procedures.
