Posterior maxillary segmental osteotomy concomitant with sinus lift using a piezoelectric device

Area of Science:

• Oral Surgery
• Dental Implantology
• Periodontology

Background:

• Tooth loss causes functional and esthetic issues, potentially leading to adjacent tooth movement and extrusion of opposing teeth.
• Traditional treatments for collapsed occlusal planes include occlusal adjustment, crowns, orthodontics, and segmental osteotomy.
• Segmental osteotomy is effective but highly invasive, carrying risks like hemorrhage and tissue necrosis.

Observation:

• Piezoelectric devices offer a minimally invasive alternative in oral surgery, known for soft tissue preservation.
• This report details a bilateral posterior segmental osteotomy using piezoelectric devices.
• The procedure aimed to correct a collapsed occlusal plane with sinus mucosa elevation.

Findings:

• The use of piezoelectric devices successfully preserved the integrity of the sinus membrane during the osteotomy.
• The posterior superior alveolar artery's integrity was also maintained throughout the procedure.
• This demonstrates the feasibility of piezoelectric technology in complex segmental osteotomy.

Implications:

• Piezoelectric devices may offer a safer, less invasive alternative for segmental osteotomy in correcting occlusal plane collapse.
• This technique could reduce complications associated with traditional segmental osteotomy.
• Further research can explore the broader application of piezoelectric surgery in complex dental reconstructions.
