Designed to roughen the surface of ceramic dental restorations in order to promote a stronger bond to the patient’s dentition, dental porcelain etchants are often suitable for intraoral as well as extraoral use. These materials can be used when preparing a new crown for seating, or when preparing a seated crown for or other dental restoration for repairs. Because the use of these etchants can improve bond strengths, they can be useful materials to keep on hand in your dental practice.
