What is the appropriate contact between artificial and natural teeth in partial dentures?

The appropriate contact between artificial and natural teeth in partial dentures is characterized by a slight touch on the balancing side. This minimal contact is designed to allow for functional movements during chewing while preventing excess force or pressure on the remaining natural teeth, which could lead to discomfort or undesirable movement.

A slight touch ensures that the artificial teeth support the natural teeth effectively without causing stress or misalignment. It promotes a balanced occlusion, which is important for the overall oral health of the patient. Proper occlusal adjustment is crucial in the design of a partial denture to ensure that the forces during mastication are evenly distributed, allowing for durability and comfort.

In cases where the artificial and natural teeth should not make contact at all, it could lead to a lack of stability in the partial denture, resulting in an inefficient chewing function. Conversely, full contact on all sides could lead to wear and tear on the natural teeth, as well as potential discomfort from excessive forces during occlusion. Limiting contact to only the anterior teeth does not suffice for overall function, as posterior teeth also play a critical role in chewing and should be included in the assessment of occlusal relationships.
