There are many procedures where dual ultrasonics can improve performance and efficiency. A simple example of a two-tip procedure might be the removal of a post. Sometimes it is advantageous to use a small ultrasonic tip to remove a post luting agent like composite and then utilize a larger tip, like a paddle tip, for application of higher, more gross ultrasonic energy. Not only does the dual ultrasonic handpiece control allow a clinician to use two different tips concomitantly but also he/she can use these tips at different energy levels depending on the tip activity, manufacturer’s recommendations and intended use.
Another area where the Dual Ultrasonics can really come in handy is refinement of an endodontic access cavity when ultrasonics is being utilized. Sometimes it is the strategic removal of tenacious pulp stones or troughing an isthmus in evaluation of the presence of a middle mesial in a lower molar where more than one ultrasonic tip can allow your endodontic spelunking to simply be more efficient. More than one ultrasonic tip can be very useful for careful, safe, vision-enhanced exploration of an area looking for the sometimes-elusive MBII.
The examples listed here are just a few of the many areas in clinical dentistry and endodontics where multiple ultrasonics tips used synergistically can make a difference. As more clinical procedures are done with ultrasonics and more tips are developed, the advantages of having dual ultrasonics delivered ergonomically will undoubtedly increase.
Whether it be a relatively simple ultrasonic procedure or a more complex one there is little doubt that more than one ultrasonic tip ready to use and set at the proper energy level can allow the procedure to take less time and be more cost effective in the process.
