Comparative study of two autogenous graft techniques using piezosurgery for sinus lifting.

Area of Science:

• Oral and Maxillofacial Surgery
• Regenerative Medicine
• Biomaterials

Background:

• Maxillary sinus lifting is a common procedure for dental implants.
• Sinus membrane perforation is a potential complication during this surgery.
• Minimally invasive techniques are sought to improve safety and outcomes.

Purpose of the Study:

• To compare two ultrasonic techniques for autogenous bone grafting in rabbit maxillary sinus lifting.
• To evaluate the efficacy and safety of particulate versus shaved bone grafts using ultrasonic devices.

Main Methods:

• Ten rabbits were used, with nine undergoing maxillary sinus augmentation.
• Autogenous bone grafts (particulate and shaved) were collected from the skull using an ultrasonic device.
• Bone density was assessed via computed tomography 90 days post-grafting and statistically analyzed.

Main Results:

• No statistically significant differences in bone density were observed between the particulate and shaved bone graft techniques.
• Both ultrasonic grafting methods were comparable in terms of bone regeneration within the maxillary sinus.

Conclusions:

• Piezoelectric ultrasound is a safe tool for maxillary sinus augmentation in rabbits.
• The technique allows for the maintenance of sinus membrane integrity during surgical procedures.
• Ultrasonic harvesting of autogenous bone for sinus lifts is a viable and safe approach.
