De l’intérêt du bistouri ultrasonore en implantologie : technologies, applications cliniques

The ultrasonic lancet is a surgical device able to cut out with precision hard tissue and to facilitate the solid interfaces cleavage. It uses microvibrations of intermediate frequency generated by a piezoelectric transducer and applied to titanium nitride hardened and/or diamond-coated inserts. With its vast range of inserts, it finds many applications in oral and maxillofacial surgery, such as non-traumatic dental avulsions, root surfacing and bone defect debridement, or cyst removal. It also proposes a simplified protocol for the sinus lift surgery. Lastly, it offers a true revolution in the bone grafting surgery by allowing precise and non-traumatic graft harvesting. This article presents its physical, technological and clinical aspects and discusses its most promising applications. Indeed, although the ultrasonic lancet remains a safe and powerful tool in many circumstances, it is however significant to define a reasoned application field to it.
