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.

Conditions

• Dental Implant
• Sinus Lifting

Interventions

Type	Name	Description
PROCEDURE	Crestal Maxillary Sinus Floor Elevation using Osseodensification	Patients will be prepared for surgery with local anesthesia and thorough oral cavity disinfection. A full thickness crestal incision will be made slightly towards the palate to enhance the possibility of achieving primary wound closure. A conservative flap will be raised, extending slightly beyond the alveolar crest, to minimize flap-related issues. After preparing the osteotomy site using Densah burs and elevating the sinus to the desired height, the implant will be inserted into the osteotomy site.
PROCEDURE	Lateral Maxillary Sinus Floor Elevation	A crestal incision with an anterior vertical releasing incision exposes the sinus's lateral wall. A mucoperiosteal flap is carefully reflected, revealing the sinus. A bony window is created using a Piezoelectric device, and after elevation, the sinus floor is carefully lifted with various curettes. Implant osteotomies follow standard placement protocol, with precautions against sinus membrane perforation. Nanobone is used as graft material, mixed with saline and gently packed into the sinus. A resorbable membrane is placed on the window's outer surface, secured with circumferential resorbable sutures, and the flap is sutured for closure.
