Maintaining a comfortable, ergonomic grasp is critical to the maintenance of operator health during
ultrasonic instrumentation.9 SWERV3 enhances chairside ergonomics for the dental professional through
the use
of the following features:
• A large-diameter ergonomic silicone handpiece rest that reduces muscle strain and enhances
clinician comfort.7
• A light-weight and well-balanced handpiece that requires less work from the clinician’s hand
and arm muscles.7
A pen grasp and use of an extraoral fulcrum are recommended, as they allow the
operator to achieve a light touch with minimal pressure against the patient’s tooth.2,7,9
