Which factor most influences the decision to use cusped or non-cusped teeth in dental practices?

The decision to use cusped or non-cusped teeth in dental practices is significantly influenced by TMJ (temporomandibular joint) problems. When a patient has issues with their TMJ, such as joint pain or dysfunction, it can affect their occlusion—the way the upper and lower teeth come together. In such cases, the choice of tooth type is carefully considered to minimize stress on the TMJ and provide a functional occlusal scheme.

CUSPED teeth are often used in more complex dental restorations where a greater degree of interdigitation and stability is needed, such as in cases with a healthy TMJ that can handle the functional demands. In contrast, NON-CUSPED teeth may be selected for patients with TMJ issues to provide a more forgiving occlusion, thus reducing stress on the joint and alleviating discomfort.

By focusing on the health and function of the patient's TMJ, dental professionals are able to create a treatment plan that not only addresses the aesthetic concerns but also prioritizes the functional well-being of the patient. This is crucial for long-term success in dental restorations, ensuring that they do not exacerbate pre-existing conditions related to the jaw joints.
