Fracfinder Colors is made of a soft autoclavable material, an indispensable instrument for the practice of modern dentistry, that simplifies locating cracks in the tooth. Locating cracks with Fracfinder is quick and precise.To locate the crack, place the small indentation of the Fracfinder on suspected cusp. Ask the patient to apply pressure while gently biting on the suspected cusp(s). Fracfinder provides force when the patient bites down on the instrument. Cracked cusp is then located easily, rapidly and precisely. Fracfinder can also be used for applications such as seating crowns, fixed prosthesis, and tapping on teeth.
