PURPOSE: Ultrasonic bone cutting was recently introduced as a feasible alternative to the conventional tools of cranio-maxillofacial surgery because it offers improved precision and safety.This study examined the feasibility of minimally invasive orthodontic or preprosthetic surgery using a piezosurgery device for latero-posterior @entity1347 . MATERIALS AND METHODS: Four fresh cadaveric heads were obtained for this study. @entity3573 was performed using piezoelectric surgery. To preserve the vascular supply, only 1 vestibular incision was made during surgery. The Mectron Piezosurgery unit is a multipurpose device that uses micrometric ultrasonic piezoelectric vibrations with a variable frequency and cutting energy. The strategy for maxillary osteotomy included 1 @entity346 , and 1 palatal osteotomy performed transantrally without incision of the mucoperiosteum. The osteotomies were performed using a piezodevice (OT7-type inserts: 0.55 and 0.35mm). In total, 1 horizontal cut (3mm above the roots of the teeth), 2 vertical bone cuts, and 1 palatal osteotomy were made without incision of the palatal mucoperiosteum.Gentle dissection of the buccal fat pad was used to promote the healing of hard and soft tissues in the osteotomized zone. RESULTS: No damage to soft tissues, including the @entity2419 , occurred. The buccal fat pad was mobilized easily without requiring an additional incision. The osteotomic sites were linear and clean in the palatal aspect. The integrity of the vascular network was maintained because of the lack of @entity16 . No chisels were used during the osteotomies. DISCUSSION: This cadaveric study shows the feasibility of using piezosurgery for segmental maxillary osteotomy. This report outlines a new and simple application of segmental maxillary micro-osteotomy.
