Ultrasonic Instruments

The power of ultrasonics! Work smarter, not harder...

Wouldn't it be great to use:

  • Fewer hand instruments?
  • Instruments that don't need sharpening and that last longer?
  • Less time for subgingival debridement and less local anesthesia for periodontal debridement?
  • Less effort to remove heavy calculus, resulting in less muscle strain and hand fatigue?

If you answered "Yes!," then our new Ultrasonic Instruments course is for you.

An ultrasonic scaler used routinely reduces the need for a large assortment of hand instruments, saves time, and provides ergonomic benefits. Plus, complete prophylaxis for routine perio maintenance can often be performed with just one universal tip!

Take this course and get a complete overview of ultrasonic instruments, their advantages and limitations and guidelines for their use, so you can work smarter, not harder.

About the Authors

Fridus van der Weijden, DDS, graduated in 1984 from the State University Dental School in Utrecht, The Netherlands, where he acquired further training as a periodontist. In 1990 he received specialty certification periodontology by the Dutch Society of Periodontology and has been accredited in implantology by the Dutch Society of Oral Implantology.

Since 1986 he has divided his time between the Clinic for Periodontology in Utrecht and the Academic Centre for Dentistry in Amsterdam. The main focus of his research is the treatment and prevention of periodontal diseases. A frequent lecturer in postgraduate courses, he is author of the book The Power of Ultrasonics, co-author and co-editor of the book Preventive Dentistry, and author and co-author of 50 national and 100 international publications.

Ultrasonic Instruments

Ultrasonic instruments were introduced in periodontal therapy in 1955. Approximately 50 years later, their effects on the teeth and the periodontium have become much clearer. This nicely illustrated book explains the scientific basis and technical mechanics of ultrasonic instruments and describes techniques for using them.

When ultrasonic instruments are used correctly, and with care, they offer a welcome alternative to hand instruments. Moreover, in furcations, they appear to offer superior results. Newly modified tips that have a slim and elegant design allow the operator to provide more efficient supra- and subgingival debridement.

This book offers the key to the successful use of ultrasonic instruments. Clinical results, possible side effects, and contraindications are provided as well. A list of the literature comparing hand and ultrasonic instruments can be found at the end of the book.
