BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to an intraoral apparatus for functional rehabilitation which is used in subjects suffering from labiolingual dysfunctions.
In functional disorders (of phonation, deglutition, respiration, food ingestion, ect.) involving the orofacial sphere it is necessary for the functions to be restored. In the correction of maxillofacial dysmorphoses associated with labiolingual dysfunctions, it is imperative to carry out a functional reeducation of the oral and perioral muscle masses.
The apparatus of the present invention is indeed:
to replace the type of punitive devices which have been used hitherto and,
to replace or reinforce by a permanent and unconscious action, the myofunctional therapy techniques.
The principle of reeducation on which this apparatus is based relies on the importance of the role of reward and search for satisfaction in functional memorizing and learning.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an apparatus equipped with a fixing device which makes it possible to place various stimulating elements at the exact positions in the oral cavity which normally have to be stimulated in the various orofacial functions, both at the level of the upper jaw and the lower jaw. This attachment system permits a safe, quick and easy fixing of the stimulating elements.
The stimulating elements permit:
a permanent stimulation of the structural tissue zone involved in the function, with the apparatus being worn continuously,
the maintenance of a "meaningful signal" necessary for so that memorizing of a learning process. The variability in the sensations experienced makes it possible to prevent habituation of the movement,
the development of the oral muscles by exercise,
the reinforcement of the memorizing and of the cerebral engramming of the reeducated functions, by the activation of the reward circuits associated with satisfaction,
the placement of the active device on devices correcting associated maxillofacial dysmorphoses.
The apparatus is produced in the dental prosthesis laboratories using molds taken from impressions of the upper and lower jaws of the subject in question, and includes a removable support plate which can be formed of a material selected from the group consisting of resins, precious metals or semi-precious metals and which is equipped with dental anchoring hooks and an anterior vestibular arc (neutral or active). The active fixing device includes an attachment system which serves as a means for fixing the various stimulating elements having a satisfying physiological components (tubes, balls, sweets, cups, ect.).
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a top plan view of the apparatus of the present invention in position on a standard model.
FIG. 2 is a top plan view which schematically illustrates the attachment system of FIG. 1, with structure removed to reveal construction detail.
FIG. 3 is a top plan view similar to FIG. 2, which schematically illustrates a variation of the attachment system of the present invention.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
The attachment system of the present invention is generally comprised of two arms (of which one is freely movable) which are equipped with two helical spring members. The latter contribute to giving a certain elasticity to the wire used. A posterior spring member permits the locking of a free arm of the attachment in a closure position. An anterior spring member defines an opening of the attachment, necessary for placement of the stimulating elements.
The attachment system is made in the intrados of the apparatus for two reasons:
complete safety, it being possible for the attachment to be opened only after the apparatus has been removed from the mouth,
the device does not interfere with the awareness of the oral sensations present in each function.
FIG. 1 shows the apparatus in position on a standard model. This is a specific embodiment for the reeducation of the deglutition function.
The active device (1) is placed set ba
