APPLICATION FIELD

The present patent of invention refers to improvements introduced in intraoral vibratory devices applied no bruxis treatment wherein, notably, said intraoral device comprises a capsule and a cap, which contain the vibratory micromotor electromechanical driving system, which on its turn, develops vibrating movements inhibiting the patient's parafunctionai movements.

BACKGRGuN F OF THE ART

Bruxism co sists of a parafunctionai and daily dysfunction where n involuntary, rhythmized and spasmodic movements allow teeth grinding or cle chi g, usually occur ing du ing sleep and, hen it is not diagnosed timely, may bring consequences to the masticatory system, temporomandibular disorders, such as temporomandibular arthritis , better known as "TMA", dental enamel wear, head and ears aches, among other inconveniences .

In general, causes for triggering bruxism are related to ps chological factors, such as, emotional stress, repressed aggression, anxiety, anger, fear, frustratio and stress, and the diagnosis is IB2012/053745

usually made after said conseouences manifest.

Currently there are several types of t eatment by means of using inter occlusal plates associated to relaxing therapies, ana said plates reduce night muscular activities, in addition to protecting teeth from wearing caused by the habit.

Said plates are removable oral appliances made of silicon or acrylic resin, which are applied between the maxilla and the jaw, and tney may be lower or upper ones, whose function includes mastication neuromuscular system stabilization, in order to create a mechanical disadvantage for paraf unctional forces.

Despite the advantages obtained with said occlusal plate by obtaining a harmonic relationship between the mastication muscles, temporomandibular articulation and the teeth, said plate does not inhibit involuntary bruxism movements, working only as immediate correction.

Another existing way to minimize pain caused by bruxism consists of applying infrared wave laser, which is used for reducing muscular pain, imitating nervous impulses that generate muscles movement, promoting muscular relaxing y means of endorphin release, which is known for relaxing and 2 053745

BRIEF DESCRIPTION OF THE INVEN ION

Considering everything that has been exposed, one objective of the present invention is to provide a vibratory intraoral device oo inhibit bruxism, composed by capsule and cap, which contains a vibratory micromotor electromechanical driving system, which, when driven by means of pressure, vibrates in such a way to cause one individual to be sensitized and interrupts the biting action or mandibular pressure. The in raoral device is provided in two models, a right model and another left model, perfectly identical to each other, except for the inverse shape.

The right ana left models were developed to meet the functional requirements, as well as to allow its indust Γ 1 S _ 1 Z σ tion within the standards ensuring standardized reproduction of their main characteristics by means of compatible manufacturing processes, also providing manufacturing costs ensuring the economical- inancial feasibility for manufacturing and commercialization.

Said electromechanical driving system is configured by a fixed contact and a moving contact, which, y means of a punctual electrical contact, work as a on / off switch for said vib atory micromotor, which, on its turn, is fed by electric batteries. Said moving contact and fixed contact may be replaced wi t h other transduc i ng devices , micro electromechanical devices, sensors of the membrane ieyboard type or a piezoelectric type sensor.

Said capsule is made of injected thermoplastic or another appropriate material which meets the dimensional requirements and the physical- chemical properties required for application, i.e., or another material and by means of different conforming or milling processes industrially accepted, and said capsule is configured i a si gle piece and provides housings and seating means and adjustment of a pair of batteries, a vibratory micromotor, fixed contact and moving contact, in additxon to providing channels for application of adhesive resin for fixing the cap.

The main advantages of said capsule are:

a) Electrical insulation of internal components, in addition to resistance to liquid solutions, keeping the integrity of the moving contact;

b) Anatomical shape providing more comfort and less trauma durinq the device adaptation to the tissues on .nternai wall of the cheek mucosa;

prosthe x c s :

i. Definition of the application on the upper arcade or lower arcade of one patient, observing the teeth anatomy, the on/off electromechanical switch starting and the adaptation of the device to the patient, causing the best comfort possible curing its use;

ii , Molding of one determined arcade performing the procedures to obtain the plaster model of the respective arcade, and the plaster model will have an insulator for acrylic resins applied along the whole molded surface of the patient arcade, including the soft tissues molded surfaces;

iii. Preparation of tne left model and right model, individually, in order to define the positions along the chosen arcade, applying on the internal area of the devices a universal adhesive for tray

iv. Preparation of a silicon-based compound having a catalyst starting the polymerization process of said compound, and after the preparation the compound is applied throughout the area formed by surfaces on which the universal adhesive for tray was applied, and the amount shall be enough to involve the whole area to be molded;

v. Positioning of left and right devices individually along the determined patient arcade, prioritizing the 2053745

11

position to favor the best actuation of the cn/off electromechanical switch of the device, considering that the teeth cuspids ends shall meet the internal occlusal surface of the device, and the central area of the electromechanical switch shall be avoided concerning teeth contact, mainly before the moment when the vibratory micromotor component driving occurs;

vi . After the positioning the patient shall close the mouth and clench the teeth hard enough to drive the electromechanical switch, promoting the vibratory micromotor starting, and this condition gees on until the silicon compound polymerization occurs, when it will be removed from the patient's mouth;

vii . After it is removed from the patient's mouth, the silicon compound will be polymerized with the device, forming a silicon mold of t e area where it will be later applied over the plaster model of said arcade. The excess silicon compound is removed from the undesired areas in the devices;

viii . Left and right models are positioned in the piaster model, and they shall ta ke e same posi t ions determined in the device positioning on the patient's arcade;

ix . After positioning the devices in the plaster model, a self -polymer izable acrylic resin is applied on the area comprised between the left model and the right model, forming a connection bridge between them, respecting the dental l mits and preventing invasion over soft tissues. Thereafter, the resin is applied on any occlusal surfaces not covered by the devices. The excess resin are removed while it is in the plastic phase, providing the shape that Peso adapts to the patient's arcade. The devices remain in the plaster model until complete resin polymerization, when they are removed, configuring the plate;

x. The silicon molds are removed from the devices cental ne a in the plate, filling the spaces ith the same se 1 f -pol yme r i zabi e acrylic resin used before;

xi . The plate is repositioned in the piaster model, suffering pressure until the devices take the same positions previously defined in the patient's arcade. The plate remains m the plaster model until complete polymerization of the acrylic resin;

xii. The plate is submitted to a finishing process using metallic milling machines to relief the excess resin on undesirable areas, and also to provide to s u r face s with any contact with soft tissues w ith polished finishing . Final finishing is pe formed by means of rubbers and emery papers over the external surface of the polymerized resin. During the finishing process caps and capsules milling s all be avoided, ror both devices, keeping their airtight: assembly intact; and

xiii . The plate is tested on the pa ient's arcade, by observing the perfect driving cf devices on both sides, and checking the need of any adjustment for better adaptation of them to the patient, providing them with the best comfort possible.

On the other hand, in case the surgeon needs the participation of specialized prosthetics, more precisely for positioning the intraoral device in the plaster model of the patient's arcade plaster model, the procedures are the following: i . The dentist performs the procedures to obtain the piaster model of the upper and lower patient arcade; i. The dentist makes the bite recording in wax;

ii . The dentist de elo s one spatia 1 recordi ng of the occlusal plan with the facial arch;

iii , The dentist assembles the plaster models in the articulator reproducing the patient's bite and sends it to the prosthetics;

i . The prosthetics performs tne positioning of left model and right model devices over the chosen arcade, choosing the upper one or the lower one;

v. Tne prosthetics ositions the devices individually along the patient chosen arcade, prioritizing the positron favoring the best starting of the cn/off electromechanical switch, considering th t the teeth cuspids ends shall rr.eet the internal occlusal surface of the device. T e central rea of the electromechanical switch shall be avoided concerning teeth contact, mainly before the moment in which the vibratory micromotor component driving occurs ;

After the positioning of the intraoral device in the plaster model in the patient's arcade, the prosthetic makes the support for the devices in self -polymer izabie acrylic resin, and he may choose among the following procedures :

• Method A:

After positioning the devices in the plaster model, a selr-poiyraerizabie acrylic resin is applied in the area comprised between the left model and the right model, orming a connecting bridge between them, observing the dental limits and preventing the invasion over soft tissues. Thereafte , resin is applied to an occlusal surfaces ot covered by the de ices. he excess resin is removed while it is in the plastic phase, giving the shape that best adapts to the patient's arcade plaster model . The devices remain in the plaster model until complete resin polymerization, when they are removed, configuring the plate.

• Method 3:

ith the devices already positioned in the piaster .T.odeJ , the prosthetic makes, in wax, the bridge and the ends of tne supporting plate to said devices;

- Wi h the wax place containing the devices over the plaster model, one prosthetic includes the whole set in a metallic muffle filled witn previously insulated plaster;

- After pressing the plaster, the prosthetic removes , with heated water, the wax and the silicon from the plaster model with the devices included in it;

- The prosthetic fills the space left by the wax and the silicon with thermo-polymerizable resin, and closes the muffle with pressure. Its polymerization shall be made under heat;

After the polymerization time, the prosthetic opens the muffle and performs plate finishing .

Another procedure used for installing the device, performed only by tne dental surgeon, comprises positioning the product directly on a pre-moided intraoral plate, which procedure simplifies all procedures, due to the following factors :

i . Left model and right model devices are already 12053745

16

contained in the intraorai plate;

ii. The intraoral plate has several sizes and shapes models . The dentist; only has to choose the one that best adapts to the patient's arcade;

iii. The intraoral plate enables customized adjustment of the "boil and bite" type to ohe patient's arcade; iv. The time for intraoral plate adjustment is considerably lower than the ether methods /

. The application of the intraoral plate does not require complementary materials usee in tne otner methods ;

vi . Procedures for intraoral plate application and ad ustment are considerably simpler than the other methods, reducing the possibilities of mistakes and devices damaging.

Said vibratory intraoral device may be assembled on several types of dental appliances made of resins, plastics, metals, silicons or other biocompatible supporting materials, by following the procedures and positioning methods, and said appliances may be of the palatine plate type, Hawley's plate, Bicnatcr appliance, Planas' appliances, appliances for snoring, appliances for apnea, palatine cutout, bruxism plates, etc.
