Transcrestal Sinus Lift Using Osseodensification Versus Lateral Window Technique

Transcrestal Sinus Lift Using Osseodensification Versus Lateral Window Technique With Simultaneous Implant Placement

The aim of this study is to evaluate the transcrestal sinus lift using Osseodensification versus lateral window technique with simultaneous implant placement.

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.

Inclusion Criteria:

• Patient with residual bone height from 4-6 mm and bone quality is D3 or D4.
• Patients had to require implant treatment in the posterior maxilla.
• All patients will sign a consent form before the study.

Exclusion Criteria:

• 1- Sinus pathology that precludes routine sinus augmentation.
• All contraindications of dental implants.11,12
• Heavy smokers.
