A) Raised; lowered
B) Lowered; raised

Answer 1

When polishing the mandibular arch, the patient's chin should be raised, and the chin should be lowered for the maxillary.

Step-by-step explanation:

When polishing the mandibular arch, the patient's chin should be raised, and the chin should be lowered for the maxillary. This positioning allows for better access to the individual teeth in each arch. By raising the chin for the mandibular arch, the dental professional can effectively polish the upper border of the mandibular body, which serves to anchor the lower teeth.
