The type of temporomandibular joint (TMJ) noise that is associated with the best prognosis is recognized as the early opening and late reciprocal click. This specific type of clicking is typically indicative of a disc displacement that may still have the capability of returning to its anatomical position during the motion of the jaw.

In the context of TMJ disorders, early opening and late reciprocal clicks suggest that the disc is able to reposition itself before closing, which implies a more favorable relationship between the articular surfaces and the disc. This can often lead to more stable joint function and an overall positive outlook for treatment outcomes.

Additionally, the presence of a reciprocal click generally indicates that the condition can still respond to conservative management strategies, such as physical therapy or splint therapy, resulting in significant improvement over time.

On the other hand, continuous crepitus is often associated with more severe degenerative joint disease or advanced disc displacement without reduction, suggesting a less favorable prognosis. Joint locking noise typically indicates more severe dysfunction, often involving an irreducible disc. A single noise on closure can also indicate a specific episode of dysfunction, which may not provide enough information about the underlying joint mechanics compared to the diagnostic clarity offered by the reciprocal click pattern.
