In dentistry, piezo-surgical techniques have recently increased largely its field of indications. This ranges from endodontic procedures to several other bone cutting techniques in oral surgery and implant dentistry.
Ultrasound technology results in the power of a surgical cutting technique, which is able to selectively interact with hard and soft tissue. The key factors of the cutting action are an approximately 0.7 mm osteotomy slot, a laminar stream of cooling fluid and a selective cut–working frequency for hard tissue at 25-30 kHz and for soft tissue at 50 kHz.
This results in favourable features such as (1) a pressure-less cut, (2) a precise cut (20-60 μm), (3) a cool cut (laminar flow), (4) a selective cut for different tissues (protecting the Schneiderian membrane and the inferior alveolar nerve), and (5) a bloodless cut (cavitation effect).
The clinical use comprises indications such as tooth extraction, harvesting bone for the different augmentative procedures, splitting alveolar bone, preparation of the Schneiderian membrane during sinus floor elevation procedures, exposing the inferior alveolar nerve and root-end-preparation during endodontic surgeries. This lecture intends to summarize the clinical applications of piezosurgery and compare this technique with conventional cutting techniques.
An overview and a critical analysis of the present indications for this technique will be presented in this clinically oriented presentation that will include the most relevant literature in the field.
