Ultrasonic cleaners are found regularly in dental healthcare. The College of Dental Science (CDS) in the Medical University of South Carolina (MUSC) has a post on polishing the surfaces of a dental tooth cap. This polishing is crucial but it requires both special manipulation and equipment. The occlusal surface needs to be processed first. Use a Busch Bud Bur to smooth the grooves. Then BBC polishing compound is used to smooth and polish the occlusal surface with a Robinson bristle brush. Ultrasonic cleaning of the cast tooth cap is then done to remove the BBC polishing compound. Finally, they describe how to polish the axial walls and margins.
