What instructions would be given to a patient obtaining a bite registration?

The correct instruction for a patient obtaining a bite registration is to close normally and gently. This approach allows for an accurate impression of the patient's occlusion, capturing the relationship between the upper and lower teeth in a relaxed and natural position. By advising the patient to close normally, the dental professional ensures that the bite registration reflects the patient’s typical bite, which is essential for creating dental restorations or appliances that fit comfortably and functionally.

When closing gently, the patient can avoid exerting excessive pressure on the bite registration material. This careful closure allows for an accurate recording of the occlusal surfaces and is particularly important since overly tight contact can distort the material and result in an inaccurate representation of the bite. A gentle close also minimizes patient discomfort during the procedure.

While options recommending a tight close or a wide open mouth are not appropriate for obtaining a bite registration, keeping the mouth partially open does not allow for proper articulation of the bite. Thus, closing normally and gently is the optimal instruction for achieving a precise and effective bite registration.
