Explanation:
The student asked whether dental hygienists and licensed dental assistants are permitted to take impressions and bite registrations for various stages of fixed and removable prosthesis creation. According to standard dental practice and regulations, dental hygienists and licensed dental assistants should not take impressions and bite registrations for the final seating of fixed and removable prostheses. This stage typically requires a more advanced skill set and precise adjustments that licensed dentists or prosthodontists are qualified to perform. While dental hygienists and assistants can take preliminary impressions for initial fitting or laboratory fabrication, the final adjustments to ensure proper fit and occlusion of the prosthesis are the responsibility of the dentist.
