Answer:

When opening the mouth, the lower jaw moves down and forward, with the condyle sliding in the TMJ socket. Closing it involves upward and backward movement. During chewing, upper and lower teeth come into contact, aided by side-to-side movements for efficient grinding. Proper alignment of upper and lower teeth (occlusion) is crucial for dental health and effective function. Issues in this articulation can cause discomfort and dental problems, requiring specialized dental care.
