A flashing-light method for recording centric relation.
A flashing-light system has been described which provides a simple method for ensuring equalized pressure in recording the relationship of the mandible to the maxillae. The wires that protrude from the mouth do not appear to create any discomfort or distraction during the procedures. This method tends to be more comfortable than extraoral or intraoral tracing techniques. The method may create patient fear because an electrical device is used in the oral cavity. In addition, if the metal surfaces (pins and cups) are not fully coated with wax, there may be contact with adjacent soft tissue, which creates an electric sensation.
