Maxillary sinus augmentation using mandibular bone grafts and simultaneous installation of implants. A surgical...

Area of Science:

• Oral and Maxillofacial Surgery
• Dental Implantology
• Bone Grafting Techniques

Background:

• Partially edentulous patients often present with insufficient alveolar bone height in the posterior maxilla.
• Limited interarch distance can preclude traditional onlay grafting for sinus augmentation.
• Maxillary sinus augmentation is crucial for dental implant success in atrophic maxillary ridges.

Purpose of the Study:

• To present a specific surgical technique for maxillary sinus augmentation.
• To evaluate the simultaneous placement of dental implants with this augmentation method.
• To address the challenge of insufficient bone height in partially edentulous posterior maxilla.

Main Methods:

• A mandibular bone graft from the symphyseal region was utilized for sinus augmentation.
• A rectangular osteotomy of the lateral sinus wall was performed, preserving the sinus lining.
• The bone graft was placed in the created space, followed by immediate implant fixture installation.

Main Results:

• The described technique allows for maxillary sinus augmentation and immediate implant placement.
• The procedure was performed under local anesthesia without major complications.
• The method proved uncomplicated with no observed patient disadvantages or significant pre/postoperative issues.

Conclusions:

• This technique offers a viable solution for maxillary sinus augmentation in cases with limited interarch distance.
• Simultaneous implant placement is feasible with this mandibular bone graft approach.
• The procedure is well-tolerated by patients and appears to be safe and effective.
