Optimising joint space and function with aligner orthodontics: Part 1

Joint space width is a crucial parameter. If joint space is reduced, resulting in joint space narrowing, degenerative osteoarthritis may develop, causing a loss of function and subsequently leading to pain. Degenerative osteoarthritis must be distinguished from inflammatory rheumatoid osteoarthritis in a differential diagnosis. The cause of degenerative joint disease across all joints is continuous improper loading. With the help of an occlusal correction, which can be performed both orthodontically and restoratively or through a combination of the two approaches, it is possible to positively alter the temporomandibular joint space. Due to the unique connective tissue structure of the temporomandibular joints, remodelling can be performed throughout life.
