Implant placement in the posterior maxillary region is often compromised due to anatomic limitations. Often, factors like inadequate vertical dimension, poor bone quality, and undercuts result in placement of shorter and/or angled implants. The bone-added osteotome sinus floor elevation technique can be employed in many clinical situations that involve minimal bone height, resulting in increased bone height and placement of longer implants. This article will briefly review the literature and provide a detailed description of the technique as well as present multiple cases in which this procedure was used.

Comparison of 4 sinus augmentation techniques for implant placement with residual alveolar bone height ≤3 mm.

This study compared implant outcomes following maxillary sinus floor augmentation (MSFA) in edentulous patients with a residual alveolar bone height ≤3 mm. Four techniques were evaluated: 1-stage bone-added osteotome sinus floor elevation procedure (BAOSFE) with simultaneous implant placement; 2-stage BAOSFE with delayed implant placement; 1-stage lateral window sinus floor elevation with simultaneous implant placement; and 2-stage lateral window sinus floor elevation with delayed implant placement. Patients were followed for 18 to 72 months (mean: 52.

Background: We performed maxillary sinus floor augmentation using the crestal approach and beta-tricalcium phosphate (β-TCP) and a long-term evaluation using cone-beam computed tomography (CBCT).
Methods: Twenty-three patients (30 implants) underwent sinus floor augmentation using the osteotome technique. Subjects underwent CBCT imaging before surgery, immediately after surgery, and at follow-up (≥ 3 years after surgery).

Context: To compare optical density (OD) and fibrinogen content of leukocyte-rich and platelet-rich fibrin (L-PRF) generated by standard protocol (2700 rotations per minute [RPM] for 12 min) versus relative centrifugal force (RCF)-adjusted protocol across two widely used laboratory centrifuges with swing-out rotors.
Aims: Centrifuges for PRF production generate forces in excess of 800 g. The study aimed to evaluate OD, fibrinogen content and effectiveness in bone-added osteotome sinus floor elevation (BAOSFE) of leukocyte-rich and platelet-rich fibrin (L-PRF) generated by the standard protocol (2700 RPM for 12 min) versus a RCF-adjusted protocol to generate precisely 400 g of force across two centrifuges with swing-out rotors.
Purpose: The aim of this study was to clinically and radiographically compare the trephine core procedure and the bone-added osteotome sinus floor elevation technique in the augmentation of the sinus floor.
Materials And Methods: A single site in each subject requiring sinus augmentation where the residual bone height was ~4 mm was randomly allocated to either the trephine core procedure or the bone-added osteotome sinus floor elevation technique. Measures of bone fill and bone height were also acquired through scans from cone beam computed tomography obtained before the sinus augmentation procedure (baseline) and before implant placement at approximately 6 months postoperatively.
Comparison of three different methods of internal sinus lifting for elevation heights of 7 mm: an ex vivo study.

Background: Various techniques are available for elevating the sinus membrane. The aim of this study is to evaluate three methods of indirect sinus floor elevation regarding elevation heights of 7 mm on the outcomes of membrane perforation, length of perforation, and time required to perform the procedure.
Methods: Three different methods for indirect sinus lifting, bone added osteotome sinus floor elevation (BAOSFE), sinus floor elevation with an inflatable balloon, and crestal approach system (CAS kit) from OSSTEM, were assessed for their ability to lift the sinus without causing laceration of the Schneiderian membrane.
