Osteotomy and membrane elevation during the maxillary sinus augmentation procedure. A comparative study:...

Area of Science:

• Oral and Maxillofacial Surgery
• Periodontology
• Implant Dentistry

Background:

• Maxillary sinus floor elevation is a common procedure for dental implant placement.
• Conventional rotary instruments and piezoelectric devices are used for osteotomy creation.

Purpose of the Study:

• To compare the performance of piezosurgery versus conventional rotary instruments in maxillary sinus floor elevation.
• To evaluate clinical parameters including osteotomy dimensions, surgical time, and complications.

Main Methods:

• A randomized-controlled clinical trial with a within-patient design was conducted.
• Thirteen patients underwent bilateral maxillary sinus augmentation.
• Osteotomy was performed using piezosurgery (test) and rotary burs (control).

Main Results:

• Osteotomy area was slightly larger with conventional burs (151.2 mm²) than piezosurgery (137 mm²).
• Surgical time was comparable: 10.2 min for rotary vs. 11.5 min for piezosurgery.
• Membrane perforation rates were 30% (piezosurgery) and 23% (rotary), with no statistical significance.

Conclusions:

• Piezosurgery and conventional rotary instruments showed no significant differences in clinical parameters for maxillary sinus floor elevation.
• Both techniques are viable options for sinus augmentation procedures.
