Manual and instrumental FAL and Cadiax

The jaw joint is the most complex joint in our body. Not only because it is a so-called "turn-and-slide joint", but also because when the right jawbone moves, so does the left one. In addition, the left jawbone moves to the middle while the right one may either not move at all, or in random directions.
All movements, in particular the non-physiological ones, may now cause pain - either by pressure on the so-called bilaminar zone, located behind the jaw heads or by irritation caused by a shifted discus (so-called "shock absorber" between jawbone heads and jaw sockets). However, pain may also be released by disruptions of different jaw structures.

To find the cause of the patients pains, precise diagnostics with accompanying examinations and individual questioning must be carried out.

During the following functional analysis, a detailed examination of the chewing system is carried out. Considering the results of this examination, suitable procedures to release or remove pain are arranged. According to the diagnosis, other approaches may be necessary to locate the source of the ache. The concluding therapy (e.g. biting rails, coping with stress caused by crunching and pressing, medicinal therapy and physiotherapy) is adjusted according to the needs of the patient.

Pains in the area of the jawbone and the chewing musculature, joint noises (rubbing and/or cracking), restriction of mandible mobility and tensing of the chewing musculature often originate in the teeth. Crooked teeth, tooth loss, defective set of dentures, poor fillings as well as the crunching and pressing of the teeth (stress) can be the cause of discomfort in the jawbone area. Due to the close proximity of jaw and ears, jaw pains are often mistaken as an ear ache. In such cases the ear, nose and throat specialist often finds no explanation for the pains. Jawbone, chewing musculature and teeth form a unity, which means that diagnostics and especially the therapy must take all components of this united system into consideration. Principally the jawbone should not be thought of in isolation, but as a part of the whole. This means that, for example, a dislocated spine or a tense back musculature may originate in the region of the jawbone and vice versa.

Causes of pain in the area of the jawbone:

  • Joint-related causes, for example misalignment of the joint disc (cracking while opening of mouth, mouth opening restriction and grater noises)
  • Arthritis (ruptured joint disc - bone rubs on bone)
  • Muscle pains - tensing of the chewing musculature by crunching or rubbing of the teeth (released by stress, missing teeth and poor set of dentures)

Functional analysis

A precise diagnostic with detailed questioning and examining of the patient is always necessary to find the cause of pains.

First a functional analysis is carried out. This includes a detailed examination of the chewing system. On account of the knowledge gained following the examination procedures, further courses of action, for example visual procedures (X-ray, magnetic resonance imaging), measurements etc., must be taken.

According to the diagnosis, different therapies can be indicated, e.g. bitting rails, coping with stress (crunching, pressing), medicinal therapy and physiotherapy. This reaches from light grinding of the interrupting contacts in the available teeth up to a newly formed set of dentures.

Manual and instrumental analysis

Concerning the diagnostics, a functional and instrumental analysis must always be carried out before the previously mentioned visual procedures.

The difference between manual and instrumental functional analysis is the they basically pursue different purposes. Manual functional analysis covers the structures of the jawbone which have fallen ill. So-called “pressure technologies” determine the damaged structures by putting adequate pressure on the jawbone. With suitable experience and technology the finest damaged areas can be identified.

Instrumental functional analysis, primarily depends on the individual movement of the jaw, as there can be considerable differences. Either the motion path is monitored on paper records two-dimensionally, using old technologies, or is analyzed by means of electronic writing utensils and computer support three-dimensionally. This way the articulator (also called chewing simulator) is essentially programmed to analyze the motion paths and determine the damaged places more precisely. Particularly here the Cadiax, IPR and DIR system should be applied.
