Description

Owner: FKS HOLDING SRL, Via Uberti n.99 – 47521 Cesena (FC), Italy. Title: Bite-type orthodontic device. * * * * * 5 DESCRIPTION The present invention relates to a device bite-type orthodontic appliance, i.e. freely wearable by the user by simply holding it between the jaws and jaw placed in natural closed mouth position, and 10 equally freely removable in mouth position open, so that it can be used even in some cases only Times of Day. STATE OF THE ART In the sector, orthodontic devices are known one-piece bite type modeled after those designed originally by Soulet and Besombes and described in patents FR67616 and FR1104897. 20 Hereafter, the inventor of the present application patent has greatly improved and specialized such devices, introducing new features, customized according to the patient, as per the subject of related patent applications. 25 For example, it made devices more functional and personalized: - through the use of dilating inserts that allow you to customize the active zones, such as described in Italian patent 102014902228172; 5 - by using bumps in places customized teeth push direction horizontal, as in Italian patent 102014902305641; - through the use of different materials in the occlusal plane as described in the Italian patent 10 102016000044898; - through the use of elastic occlusal planes, a boundary wall on the labial side, and a stimulus of the tongue on the lingual side as described in Italian patent 202016000084930; 15 - by means of a notch on the lingual ramp as described in Italian patent 202018000002440; - through inclinations of the occlusal plane such as described in Italian patent 102019000018518; - by means of a tilting support surface in 20 consequence of the bite, as described in the patent Italian 102020000022246. All these, and other features, are useful in designing orthodontic devices specifically 25 customized for the different needs of each patient, so depending on the specialization they are worth diversifying each orthodontic device specialized from others. For this reason we will indicate these features, and other known or future ones, such as 5 specialized or first-type features. The inventor, however, realized that it is possible further enhance devices with features specializing by adding features 10 universal, that is, common to all, regardless of functionality of the device and the specific problem of the patient. These universal features are also called of the second type and, as mentioned, they want to be able to be common to devices that instead differ in terms of 15 specialized features. The technical problem that the present invention wants to solve can be well understood by analyzing the need to take biomechanics into consideration of the palate in the design of a device 20 orthodontic of any kind. The palate is divided at the bony level into premaxilla and maxilla, whose borders are highlighted from the incisor-canine suture that runs from the canine at the beginning of the median palatine suture. 25 These two areas have embryonic origin profoundly different, especially the premaxilla, which is the nasal area, has a vertical origin, while the horizontal maxilla. This makes their action generally 5 different. To understand what action we are talking about, It is necessary to understand that these two areas are not static between them, but are to be considered as areas of freedom of both posture and growth, thanks to the sutures 10 of them. It can therefore be understood that the premaxilla requires a natural freedom of movement in the sense vertical to the maxilla, and the latter has in its turns an elective action in a horizontal sense. 15 The need therefore remains latent in the sector to allow for device design bite-type orthodontics respecting the principles biomechanics of freedom of movement between premaxilla and maxilla. 20 Therefore, a general purpose of this invention is to solve completely or partially the problems of the prior art. A preferred object of the present invention is to provide an orthodontic device that allows 25 the natural biomechanical movement between premaxilla and maxilla. Another preferred purpose of this invention is to allow to build orthodontic devices differentiated from each other first 5 specialized features and having at least one in common second universal freedom of movement feature natural biomechanics between premaxilla and maxilla. Another further preferred purpose of this invention is to provide an orthodontic device 10 of a bite type that allows biomechanical movement natural between premaxilla and maxilla easy and economical realization. GENERAL INTRODUCTION The purposes are achieved by a device bite-type orthodontic as indicated in the claims attached. 20 DETAILED DESCRIPTION Additional features and benefits of this utility model will be better understood from the following detailed description of its embodiments 25 favorites, made with reference to the attached drawings and given for indicative and non-limiting purposes. In such cases drawings: - Figure 1 illustrates an orthodontic device of bite type according to the present invention, in view 5 in plan from above; - figure 2 is a side view of the device of figure 1; - Figure 3 is a bottom plan view of the device of figure 1; 10 - Figure 4 is a front view of the device of figure 1; - figure 5 is a rear view of the device of figure 1; - figures 6 and 7 are perspective views of the 15 device of figure 1, from two observation points different; - figures 8 to 12 represent forms of alternative implementations in which you already carve according to the The present invention is applied to bite devices 20 with different specializing characteristics than that of the previous figures. With reference to figure 1, a bite-type orthodontic device according to the 25 present invention, indicated as a whole by the reference number 1, and mentioned below for brevity orthodontic device or appliance. We initially describe below some universal features of the invention, although with 5 reference to figures 1 to 7 which refer to a first form of implementation. The orthodontic device 1 is of the bite type in how much is meant to be retained in the mouth of a 10 user only for jaw-to-jaw clamping in their natural position. For this purpose the orthodontic device 1 is devoid of anchoring means to the dental arches, such as, for example, means of gluing, screwing, or tightening to them. The orthodontic device 1 comprises a body main elastic band of arch shape 2, in one piece, including: - an occlusal back wall 5 of a shape 20 arch and developed substantially according to a plan occlusal PO, configured to be placed between the dental arches of a patient; in the said occlusal plane PO said occlusal back wall 5 has a perimeter external arch and an internal arch perimeter; 25 - at least one of: • An arched external wall, also called labial 10, protruding from the wall occlusal along the said external perimeter in a direction orthogonal to the occlusal plane 5 PO; • An internal arched wall, also called palatal or lingual, protruding from the wall occlusal along the said internal perimeter in a direction orthogonal to the occlusal plane 10 PO; (not present in the example of the figures from 1 to 7, but present in the forms of implementation of the subsequent figures and numbered with the reference 11) 15 where each internal wall 10 and / or external It features a pair of 20 notches positioned in a such as to divide the said wall into a central area 25 of the said arch, also called the premaxilla area, and in two peripheral areas 30 of the said arc, also called areas of 20 maxilla. In general, said orthodontic device 1 is in elastic material, so that these notches accentuate it the bending capacity. In particular, the notches are configured to accentuate the flexing capacity 25 of the central area 25 in a direction orthogonal to the plane occlusal PO compared to peripheral areas 30. These carvings are essentially in a direction orthogonal to the occlusal plane PO. As better visible in figure 5, each wall 5 internal 10 and / or external (not present in the example of the figures 1 to 7, but present in the implementation forms (of the following figures) includes a distal crest 12 from the occlusal back wall 5 and a junction point 14 to the occlusal back wall 5, and said notches 20 10 start from said distal crest 12 and extend towards called the point of union, where they preferably extend up to the said point of union 14. The features listed above are features that allow freedom of movement 15 biomechanical between maxilla and premaxilla and are universal, that is, common to all forms of implementation of the invention. It is observed that at least one internal wall 10 and / or external preferably extends respectively 20 along the entire internal or external perimeter of the wall of occlusal bottom 5, so as to delimit together with the back wall 5 at least one channel of housing of a dental arch. The illustrated embodiment shows the 25 compatibility and application of said characteristics universal with more specific functional characteristics, hereinafter referred to as specialists, and which may be valid for to differentiate this form of implementation from others of the same invention, such as those of the figures 5 from 8 to 11. Specifically, the orthodontic device of the figures 1 to 7 is characterized by the following Specializing features: - includes two external walls 10 and none 10 internal wall; the two external walls 10 in particular they extend on opposite sides of the back wall occlusal 5; - the occlusal back wall 5 illustrated supports, at the centre of the external arched perimeter, a 15 bossatura 40, for example spherical, with the function of tongue stimulation; - the occlusal back wall 5 illustrated furthermore it preferably has two shaped surfaces arched 6 and 7 opposite each other with respect to the said plane 20 occlusal PO. They are configured to receive in I support the dental arches. As shown in figure 5, said surfaces 6 and 7 are inclined at respective angles A and B less than or equal to 10° with respect to the said plane occlusal PO. 25 In practice, any orthodontic device of the bite type equipped with one or more of such walls internal 10 or external, can be built in various sizes, so as to present said 20 notches in correspondence of the points where it is most commonly found 5 the canine incisor suture. They will be described and illustrated below further embodiments of the invention, where elements equal or similar to the previous ones will be indicated 10 with the same numbers, or with the same numbers incremented by 100 or its multiples. The orthodontic device in figure 8 is indicated as a whole with the reference number 101 and 15 differs from device 1 mainly in that comprising two arched channels (13) on opposite sides of the occlusal wall at the back (5) each delimited from a respective external wall (10) and from a respective internal wall (11) and closed at the bottom by the wall 20 occlusal bottom (5). The two internal walls 11 are also extend on opposite sides of the occlusal back wall 5, as well as the two external walls 10. Each wall, external 10 and internal 11, includes the pair of notches 20. 25 The presence of the two channels, in itself, is be considered a specializing characteristic, which can be used as the only feature specializing or in combination with others specializing characteristics. These too 5 can be used alone or in combinations with other specializing features. In the example in figure 8, in addition to channels 13 is also present the specializing functionality of deformability for insertion into the main body 10 arch of at least one dilator insert 50, such as for example a wedge or a shim, of which figure 8 has been given a symbolic representation. The main body ad arch of the orthodontic device 101 may comprise a plurality of reference signs 51 which indicate to the 15 dentist some favorite predetermined points of deformation where to apply the inserts depending on the patient needs. It will be clear to an expert in the field that the deformability can be adopted with or without the presence 20 of the 13 channels delimited by both internal and external walls external. For example, the deformability for inserts is also applicable to the form of implementation of the figures from 1 to 7. The orthodontic device in figure 9 is indicated 25 in total with the reference number 201 and It differs from device 1 mainly in that which also includes both a pair of internal walls 10 that a pair of external walls 11 as the device 101 of figure 8. It also comprises a 5 lingual ramp 60, configured to accommodate support the underside of a patient's tongue, where said lingual ramp includes a central notch 62. The central notch 62 is substantially in direction orthogonal to the occlusal plane PO, therefore it is 10 also called "vertical". Called central notch vertical 62 of the lingual ramp is configured for accentuates the ability to bend in shrinkage of the main body arch, for example it is a V-section notch. 15 The orthodontic device in figure 10 is indicated as a whole with the reference number 301 and differs from device 1 mainly in the fact that it also includes both a pair of walls internal 10 that a pair of external walls 11 as the 20 devices 101 and 201. It also includes at least one notch 70 on the external perimeter of the back wall occlusal 5. It is substantially parallel to the plane occlusal PO, which is why it is also called “horizontal”. The said horizontal notch 70 allows 25 the mutual inclination of the opposite surfaces 6 and 7 of the occlusal back wall 5, or at least of part of it they are a consequence of a user's bite. The orthodontic device in figure 11 is indicated as a whole with the reference number 5 401 and differs from device 1 mainly in the fact that it also includes both a pair of walls internal 10 that a pair of external walls 11 arranged in delimit respective housing channels 13 of the two dental arches of a user respectively, 10 where the channels are closed at the bottom by the back wall occlusal 5. In figure 11 only one of the two is visible canals. It also includes at least one protuberance 80 projecting inside said channel 13 so as to provide a predetermined push point, in the direction 15 substantially parallel to the occlusal plane PO, against a patient's dental arch inserted into said canal 13. This allows you to correct misalignments between mandible and maxilla, also called malocclusions. The orthodontic device in figure 12 is 20 indicated as a whole with the reference number 501 and differs from device 1 mainly in the fact that includes two arched channels (13) on the sides opposites of the occlusal back wall (5) delimited each from a respective external wall (10) and from a 25 respective internal wall (11) and closed at the bottom by the occlusal back wall (5). The two walls also internal 11 extend on opposite sides of the wall of occlusal base 5, as well as the two external walls 10. Each wall, external 10 and internal 11, 5 includes the pair of notches 20. This form of implementation also demonstrates that just the presence of the two channels, in itself, is be considered a specializing characteristic, which can be used as the only feature 10 specialist as mentioned in reference to the figure 8. It is clear, therefore, that in general the universal features and characteristics specialists become synergistic with each other, since 15 universal ones enhance the specialized ones. In general the specializing characteristics perform a pushing action on at least one portion of the mouth, for example between teeth, palate and tongue, in response to a biting action. 20 The expert in the field will consider all possible the combinations between the specializing characteristics described. 25 GENERAL INTERPRETATION OF TERMS In understanding the purpose of this invention or utility model, the term "comprising" and its derivatives, as used herein, are 5 understood as open-ended terms that specify the presence of the declared characteristics, elements, components, groups, integers and / or phases, but not exclude the presence of other characteristics, elements, components, groups, integers and / or phases not 10 declared.
