Concerning mandibula adductors in hypertonia, hyperactivity or hypermotility this exercise will be recommended for inactivation by aimed tiring-out of the musculature.(Anatomy: 1.6, Area VII, Page 31).

Contents:

Deliberately and autogenously intensified function for a tiring-out.

Materials:

Tough chewing material, bread crust or chewing gum (possibly a piece of rubber tube).

Procedure:

- Previous exercises: Not essential, optionally ,DRAWER-IN’-EXERCISE.

-Starting position: Not obligatory.

-Starting position: Not obligatory.

- Step-by-step-description:

-1 Chewing substance is gathered.

-2 Chewing

-3 Chewing

-4 Chewing.

-Timing: A date is fixed at a definite time of the day. The action should take effectively thirty minutes.

Characteristics:

Motivation to a self monitoring, relaxing

Remarks:

For this mainly mental exercise it is quite essential for the patient not to plan useful things during the training session as reading a newspaper or watching TV.

Discussion:

With this exercise it can be expected a physical tiring-out of the musculature, while the main contents lie in its mental component: ” I will chew to exhaustion and then my muscles will have done enough grinding and pressing”. You may as well insinuate these words to the patient. Equally at the mental effect aims the above mentioned concentration on the chewing initiating likewise a psychic exhaustion or weariness and thus an additional negative charging.

There is another method quoted which requests to chew on a soft rubber or plastic tube. The tube should be about 30mm long an 8mm in diameter with a wall thickness of 1,5mm.

This TUBECHEWER should have a similar effect as described in the exercise discussed and is conducted, referring to literature, to strengthen the masticatory musculature. This method might be useful if definitely a chewing muscle weakness is evident, assuming that the dentition is in the required functional stat and the temporomandibular joint are intact.

Frequently, though, there will be no mastication muscle weakness but rather a habitual neglect (chewing laziness, hypomotility).

Much more frequently there will be observed a hyperfunction on this terrain. A thorough reinvestigation should give an answer to the conditions prevailing.

The HOSECLAMP will be performed in a way that either the said piece of a tube is squeezed held compressed in a static mode counting to a number which will result in a unilateral burdening. Better should be the use of a longer tube sticking out on both sides of the mouth thus burdening bilaterally.

A similar piece of tube will also be used with  TUBECHEWER with the later described side effect of a missing retral support while the shorter piece may be shifted about in the mouth.

Equally the PEGSQUEEZE requires the activity of the adductors when a wooden clothpeck, inserted in the premolar region, is opened and closed. This exercise should be, at least questionable from the gnathologic point of view as it is carried out unilaterally again while furthermore the retral region of the dental bows is not supported. This may cause a compression of the temporomandibular joints which is not advisable with arthropathia.

Generally remarked, with chewing of foodstuff the muscle force will be buffered and absorbed (shock absorption, control loop dynamic) (Anatomy page 25a, “I am sparing you). In contrary the compressing of items as the clothpack or a rubber tube will lead to a nonphysiologic charging of as well the parodontal tissues as the joints and may thus induce affection.

Both exercises are isodynamic  especially the  HOSECLAMP. In both cases the musculature is forced by the resilience (elasticity) of the training material to give in in a dosed way in its tone. The antagonist is not arrogated.  This means additional training demands for the agonist which are not, as mentioned above, not necessary or even inappropriate (Anatomy: I.3.5, Page 25a).

In the here discussed exercise this kind of demand is justifiable because of its tiring-out component. Nevertheless it needs not considered nonphysiologic. The physiologic straining should, in any case, be given preference as by chewing a more solid bolus.

Instructions:

Your chewing muscles are too active? That may have bad con sequences – so you should just leave it. But sometimes the muscles won’t let you simply stop them that fiddling about. Then it may be helpful to allow them to romp about in a certain way. Therefore you arrange a certain time of the day for that. At the beginning it should be half an hour, maybe in the evening before bedtime.

As the material for chewing on an old bred crust will be best. A firm double or threefold “old” chewing gum will also do it. This will, then, be chewed on for half an hour intensively and fervently, not only by the way nibbled at – left side, right side. This may, indeed, cause some lame muscles; that’s what it should!

At the end the jaw muscles will be ”shaken out”; easily and fluently up and down and all the time the “drawer” will have to stay “in”(see THE  PEA). Do not sway the jaw, not left to right and not to and fro. The chewing muscles may also be massaged  by stroking or tapping. This will let you get an unwound feeling which should continue for a long time.
