Study Overview
Brief Summary
The aim of this study is to evaluate the transcrestal sinus lift using Osseodensification versus lateral window technique with simultaneous implant placement.
Detailed Description
In Group 1, crestal maxillary sinus floor elevation will be done using Osseodensification. An incision will be made near the palate, and a conservative flap will be elevated. Osseodensification burs will be used to create an osteotomy and elevate the sinus membrane gradually. The osteotomy will be filled with bone graft, and the implant will be inserted.
In Group 2, lateral maxillary sinus floor elevation will be performed by creating a bony window in the lateral wall of the sinus. The sinus floor will be carefully elevated using sinus elevation curettes. If there's a membrane perforation, a collagen membrane will be applied. Bone substitute material will be packed into the sinus, and a resorbable membrane will be placed over the window before suturing.
Both groups will use Nanobone as the graft material.

Arms & Interventions
Group 1: Crestal Maxillary Sinus Floor Elevation using Osseodensification:
A crestal incision will be made towards the palate for better wound closure. A conservative flap will be raised, extending beyond the alveolar crest to minimize complications. In cases with 4-6mm ridge height and a need for 3mm vertical depth, a narrow densifying bur will be used, followed by wider burs to elevate the sinus membrane. The Densah® Bur will compact graft material to lift the membrane without penetrating the sinus floor. The osteotomy will be filled with bone graft substitute, and the final bur will apically propel the graft for vertical augmentation. Implant placement follows confirmation via radiography.
Intervention: Crestal Maxillary Sinus Floor Elevation using Osseodensification (Procedure)
Group 2: Lateral Maxillary Sinus Floor Elevation
In the Lateral technique, a crestal incision and mucoperiosteal flap will expose the sinus's lateral wall. A bony window is created, and when removable, sinus elevation curettes are used to elevate the sinus floor cautiously. Membrane perforations are covered with a resorbable collagen membrane if needed. Implant osteotomies follow standard protocol.
Graft material mixed with saline is gently packed into the sinus to achieve the desired bone height. A resorbable membrane is placed on the window's outer surface, and the flap is sutured for primary closure.
Intervention: Lateral Maxillary Sinus Floor Elevation (Procedure)
