Brief summary

Piezo-surgery was ﬁrst used in oral and maxillofacial surgery in 2001 by Vercellotti and colleagues to simplify maxillary sinus surgery by avoiding perforation of the schneiderian membrane. Later on ultrasonic bone cutting has been used in orthognathic procedures, extraction of impacted third molars , cyst enucleation, implant site preparation, temporomandibular join surgery , corticotomy-facilitated orthodontics, and head and neck oncological and reconstructive surgeries.

Interventions

PROCEDUREOsteotomy using piezoelectrical device

osteotomy were utilized using piezoelectric from device (Woodpeker) with its internal irrigation system. We used US2 tip using the maximum bone cutting program and maximum irrigation program for lateral maxillary wall osteotomy and USIR tip for the posterior maxillary wall osteotomy. The pterygoid osteotome was placed between the tuberosity and pterygoid plates while the hamulus is palpated palatally with the index finger to guide the osteotome direction preventing palatal perforation.With the pterygoid osteotome still in position, we used a thin osteotome to complete the osteotomy of the posterior wall of the maxilla.
