The present study describes some of the applications of ultrasound in bone surgery, based on the presentation of two clinical cases. The Piezosurgery® ultrasound device was used (Tecnología Mectron Medical, Carasco, Italy). In one case the instrument was used to harvest a chin bone graft for placement in a bone defect at level 1.2, while in the other case a bony window osteotomy was made in the external wall of the maxillary sinus, in the context of a sinus membrane lift procedure. The Piezosurgery® device produces specific ultrasound frequency modulation (25-29 kHz), and has been designed to secure increased precision in application to bone surgery. This instrument produces selective sectioning of the mineralized bone structures, and causes less intra- and postoperative bleeding. One of the advantages of the Piezosurgery® device is that it can be used for maxillary sinus lift procedures in dental implant placement. In this context it considerably lessens the risk of sinus mucosa laceration by preparing the bony window in the external wall of the upper maxilla, and can be used to complete the lifting maneuver. The use of ultrasound in application to hard tissues can be regarded as a slow technique compared with the conventional rotary instruments, since it requires special surgical skill and involves a certain learning curve.
本研究介绍了超声在骨外科中的一些应用，基于两个临床病例的介绍。使用了 Piezosurgery® 超声设备（意大利 Mectron Medical 科技，Carasco）。在一个病例中，该仪器用于采集颏骨移植物，以放置在 1.2 级的骨缺损处，而在另一个病例中，在鼻窦膜提升手术中，在上颌窦外壁进行了骨窗切开术。Piezosurgery® 设备产生特定的超声频率调制（25-29 kHz），并专门设计用于确保在骨外科应用中提高精度。该仪器可选择性地分割矿化骨结构，且术中及术后出血量较少。Piezosurgery® 设备的优点之一是可用于上颌窦提升术以进行牙种植体植入。在这种情况下，通过在上颌骨外壁准备骨窗，可以大大降低窦粘膜撕裂的风险，并可用于完成提升操作。与传统的旋转器械相比，超声在硬组织中的应用可被视为一种缓慢的技术，因为它需要特殊的手术技能并涉及一定的学习曲线。
