Dr. Christof Pertl

Piezosonics in Implant and Oral Surgery

Release Date: June 3rd, 2021

CE Credits: 1CE (Self Study)

Provider: Tamimi Academy




  • Dr Christof Pertl received his M.D. from the University of Graz, Austria in 1987 and his D.M.D. degree from the University of Vienna, Austria, in 1991.

  • He received postgraduate training at Columbia University, Department of Endodontics, N.Y. and at the Department of Oral Surgery and Oral Radiology, School of Dental Medicine, Graz, Austria. There he served as full time faculty from 1993 until 2005.

  • He spent almost one year at the Department of OMFS, Kings College, Guy’s Hospital, London, U.K.

  • From 1993-2017 Dr Pertl was part of the adjunct faculty at the School of Dental Medicine, University of Pennsylvania.

  • He joined Harvard School of Dental Medicine, Boston as a full time visiting associate professor from 1998-1999 and since then as part time faculty.

  • Since 2005 he maintains a private practice in Graz and serves as a lecturer at the Schools of Dental Medicine of Graz and Vienna.

  • Currently he is also a board member of the Austrian Societies of Oral Implantology and Endodontology.


  • The Piezo“effect” describes a physical interaction, which is used in different fields of clinical medicine, such as ultrasound diagnostic technology and extracorporeal shock wave lithotripsy. In dentistry this technology has 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 different augmentative procedure, 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 piezo-surgery 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.
