A New Technique for Minimally Invasive Maxillary Lateral Sinus Augmentation: a Case Report

Area of Science:

• Oral and Maxillofacial Surgery
• Regenerative Medicine
• Dental Implantology

Background:

• Lateral sinus augmentation is crucial for posterior maxilla bone volume expansion.
• Existing techniques, while successful, carry risks like Schneiderian membrane perforation and extended operating times.
• Insufficient bone height in the posterior maxilla presents a significant challenge for dental implant placement.

Observation:

• A novel, minimally invasive technique for lateral sinus augmentation was developed.
• This technique utilizes a specially designed bur for safe lateral bone preparation and sophisticated separators for sinus membrane elevation.
• Platelet-rich fibrin (PRF) and decalcified bone allograft were employed as grafting materials.

Findings:

• The described technique significantly minimizes intraoperative and postoperative complications associated with sinus augmentation.
• The combination of PRF and decalcified bone allograft demonstrated satisfactory efficacy in promoting bone healing.
• The specialized bur and separator system allows for safer and more controlled sinus membrane elevation.

Implications:

• This minimally invasive approach offers a safer alternative for lateral sinus augmentation, potentially improving patient outcomes.
• The use of PRF and decalcified bone allograft shows promise for enhanced bone regeneration in sinus lift procedures.
• This technique could lead to reduced chair time and fewer revision surgeries in complex maxillary reconstructions.
