Functional analysis and diagnostics of the masticatory organ

Functional analysis of the masticatory system is a dental method for assessing the individual characteristics of the patient’s jaw. A dental impression is made to measure the upper and lower jaws of the masticatory system. The chewing process and the movements of the upper and lower jaw are recorded and the functionality of the masticatory muscle is observed. Symptoms are usually due to Craniomandibular Disorder (CMD) meaning a misalignment of the skull (Cranio) and lower jaw (Mandibula). The results of functional analysis allow Dr. Jürgen Pink and colleagues to spot any dysfunctions in the form of premature contact or malocclusion and treat these accordingly. One common form of therapy is a certified DROS® splint, a customised occlusal splint which not only reduces wear on the teeth but also diagnoses and relieves the causes of CMD.

The symptoms of CMD can vary and are not always causally-associated with the jaw and musculoskeletal system. Common symptoms include:

• Clenching and grinding the teeth
• Tooth abrasion, wear
• Cracking in the jaw joints
• Exposed tooth necks
• Loosening of the teeth
• Tooth migration
• Tooth loss

A disturbed interaction between the teeth in the upper and lower jaws causing incorrect occlusion (bad bite), pushes both jaws into non-physiological positions. This creates pressure in the surrounding muscles which are put under unnaturally high strain and tension. In the long-term this can cause pain and tension in other parts of the musculoskeletal system. Tooth ache and pain in the jaw joints, face, head or neck are therefore often the results of CMD.
Even the smallest change in the chewing apparatus can lead to a severe joint dysfunction. This is understandable when you consider that night clenching and grinding lasting 15 – 20 minutes can generate a biting force of around 400 – 800 N.

Dr. Pink and colleagues dental practice recommend the certified DROS® splint concept. Find a list of the DROS®dentist here.
