Piezoelectric Advantage: Soft Tissue Protection & Rapid Healing

Piezosurgery in Periodontics and Implantology - Summary.Piezosurgery, developed by Dr. Tomaso Vercellotti in 1999, is an ultrasonic bone surgery technique operating at 25-29 kHz, generating precise linear microvibrations of 60-200 µm. Its defining feature is selectivity - cutting mineralized tissue exclusively while leaving adjacent nerves, vessels, and soft tissues unharmed. A cooled irrigant ensures thermal safety and excellent intraoperative visibility through cavitation.Biologically, piezosurgery outperforms conventional rotary instruments by promoting faster healing, early upregulation of BMP-4 and TGF-β2, reduced inflammation, and absence of thermal necrosis.Clinical applications span scaling, root planing, crown lengthening, osseous surgery, sinus elevation, ridge expansion, bone harvesting, and implant site preparation.Limitations include a learning curve, slightly longer operative time, and higher cost.Overall, piezosurgery offers unmatched precision, biological compatibility, and surgical safety in modern periodontal and implant practice.
