TECHNICAL FIELD OF THE INVENTION The invention relates to a dental appliance such as a mandibular correction orthosis and / or an orthodontic appliance. It also relates to a method for manufacturing such a dental appliance, as well as to a device for manufacturing such a dental appliance. State of the art

Different situations require the use of a dental appliance to respond to one or more disorders of a patient, said dental appliance performing one or more corrective functions, some examples of which are detailed below.

For example, in a person with poor positioning of the mandible, there are different negative consequences, including sleep apnea and snoring phenomena. In addition, such a person may experience joint pain and headaches. Finally, such a defect can also induce a negative effect on the overall aesthetics of the face. This phenomenon of poor mandibular positioning is increasing strongly today, due to the evolution of eating habits. In general, the mandible occupies a position too far back. On the other hand, the tongue must occupy a correct position at the palate. Its poor positioning, which occurs for example in a child who sucks his thumb, is at the root of many disorders including a bad influence on phonetics and breathing problems, which can lead to sleep apnea.

Finally, the poor positioning of the teeth, according to a maladjusted architecture of the jaws or the poor individual positioning of the teeth, also induces various well-known disorders, besides the consequence on the facial esthetics.

To respond to these disorders of a patient, there are different dental devices that have the function of correcting the wrong positioning or mentioned.

For example, the positioning of the mandible can be corrected by a mandibular correction orthosis, sometimes called more precisely mandibular advancement orthosis. A mandibular advancement orthosis of the state of the art is based on two maxillary and mandibular orthoses linked together by a connecting rod, which exerts a force of thrust towards the front of the mandible, while allowing its articulated movement and thus the opening and closing of the patient's mouth. Such an orthosis can be worn days and nights.

Similarly, the positioning of the tongue can be corrected by a device defining a restricted volume, said lingual envelope, which restricts the range of possible movement of the language and forces its correct positioning. Such a device is usually worn at night.

Finally, the positioning of the teeth is corrected by an orthodontic appliance which exerts repositioning forces on the teeth, and which can be worn day and night, or at night only. To date, the existing dental appliances are however unsatisfactory because they have many disadvantages among which a lack of comfort in the mouth for patients, a lack of user-friendliness during their use, a high cost especially due to their complex manufacture. In addition, these different dental devices are distinct and not combinable. Some can be worn only at night, others must be worn day and night. These dental devices are thus inherently incompatible and it is sometimes not possible to make several corrections mentioned simultaneously, with the same dental device.

The two components may comprise at least one connecting zone allowing a removable connection by interlocking or clipping of the two components or by magnetic effect.

A bonding zone of the two components may comprise a groove or a rib or at least one notch or at least one magnet.

The first component may comprise a first portion in the form of a plastic material gutter providing at least one housing for receiving a tooth and ensuring maintenance by clipping of said first component on a dental arch.

The first component may include a mandibular repositioning element and / or repositioning of at least one tooth and / or enlargement of the palate, and / or the second component may include a tongue repositioning element.

DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION The invention is based on a dental appliance comprising at least two separate components, which can be removably connected, to add or not to add one or more complementary functionalities to said dental appliance, in a flexible and optimized manner. The dental appliance may be maxillary, that is to say intended for attachment to an upper dental arch, and / or mandibular, that is to say intended for attachment to a lower dental arch. It can also include the two parts, maxillary and mandibular, linked together.

According to the preferred embodiment of the invention, the dental appliance is a maxillary appliance which comprises a first component 1, more particularly represented in FIGS. 1, 5 and 6, and a separate second component 10, more particularly represented on the Figures 2 and 7. In a variant, the dental appliance could comprise similar components but be a mandibular appliance.

The first component 1 comprises a first portion 2 for attachment to a dental arch, divided into two portions, symmetrically arranged around a median plane A-A, for a rear-front orientation in the central part of the mouth. Advantageously, this first portion 2 is in the form of two transparent plastic material gutters positioned on each side portion of the first component. Each gutter accommodates housings or cavities for receiving teeth, and allowing a maintenance of said component on the dentition by a resilient interlocking effect (clipping) on the teeth at these housing. For the sake of simplicity, we will call later "gutter" or "dental gutter" this first part 2. We mean by gutter broadly any form comprising at least one housing for total or partial positioning on at least one tooth of a patient, and coming to fix by clipping on at least one tooth of a patient. This gutter can have different shapes, include different materials and concern all or part of a patient's teeth. The housing may marry the contour of only a portion of the teeth, the walls of the gutter may have a reduced surface, or even perforated areas. In general, the gutter will extend sufficiently on the dental arch to ensure stable maintenance of said first component 1. Thus, this first portion 2 preferably extends over several teeth on each side of the dental arch. The gutter includes a vestibular wall, facing outwardly of the mouth, which covers all or part of the visible surface of the teeth, and a lingual wall, facing the inside of the mouth, covering the hidden face of the teeth. These two walls are linked by an occlusal wall that covers the top of the teeth. By these three walls which follow the shape of a tooth, the first part 2 of the first component 1 fulfills the function of maintaining the dental appliance as explained above. These walls are preferably thin and transparent. Such a first component 1 of a dental appliance thus has the advantage of being comfortable, aesthetic because not very visible, and easy to manufacture, as will be detailed later. Alternatively, any other first portion 2 for attachment to a dental arch, preferably removable, may be used, not necessarily a gutter.

Next, the first component 1 comprises occlusal release tracks or planes 3, arranged via extensions disposed above the occlusal surface of the dentition at the level of the gutters described above. The first component thus comprises two unlocking planes 3 arranged symmetrically on each lateral part of the component. The extensions thus form unlocking planes 3 or tracks, substantially parallel to the occlusal surface. The unlocking plane 3 is in particular intended to rest on the unlocking plane of a complementary mandibular dental appliance, not shown, in the closed mouth position. For this, the unlocking plane 3 has a minimum height to fulfill the unlocking function, while inducing minimal discomfort because it prevents the complete closure of the patient's mouth. In practice, this objective is achieved with a height of the order of 3 mm for each extension, which induces a positioning difference of 6 mm compared to the natural closed position if two complementary maxillary and mandibular dental appliances are used, each having complementary unlocking planes and the same geometry. With such an arrangement, this support between the unlocking planes prevents the natural imbrication of the two dental arches, called occlusion, which allows to change the natural position of the arches, which is for example to correct. Thus, the first component 1 is able to participate in a mandibular correction function.

In a variant, the unlocking plane (s) 3 may have different geometries. For example, the two planes can be arranged at different heights above the occlusal wall of the first component 1. In an extreme variant, this unlocking plane 3, above, is sufficient to fulfill the function of occlusal unlocking alone. support on the lower dental arch, in the absence of any mandibular dental appliance. On the other hand, the extensions advantageously form unlocking planes 3 which extend over a relatively large surface of the first component 1, for example corresponding to at least two or three teeth, to reach a stable support. Alternatively, these plans may have other forms, for example shortened. According to another variant, there may be more than two unlocking planes 3. According to another variant, a single plan may suffice. Finally, these planes can be associated with a setting device, type of adjustment screw, to move them in height and adjust the chosen height. According to another variant embodiment, the first component 1 does not comprise an unlocking plane, in particular for example if it fulfills only one orthodontic function.

The first component 1 according to the embodiment further comprises a palatal connecting surface 4, extending from one side portion to the other (between the two sets formed by a gutter and an unlocking plane), marrying partially the shape of the palace. This palatal bonding surface improves the correct positioning and maintenance in the mouth of the first component 1. It also forms a reinforcing spacer of the dental appliance.

Finally, the first component 1 comprises connecting zones, provided for its removable connection with a second component 10, which will be described below. A first connection zone 5 forms an arch which substantially follows the curvature of the dental arch at the lingual wall and extends from a lateral portion of the first component 1 to the other, in the frontal portion of the first component. This connecting zone forms a groove 6. A second connecting zone 7 is arranged at the intersections between the palatal surface 4 and the gutters, and is in the form of a notch.

This first component 1 is therefore suitable for attachment to an upper arch. It can be combined with any complementary dental device adapted for fixation on the mandibular arch. These two maxillary and mandibular devices can optionally be linked together, by a connecting rod, an elastic element, or any connecting element, for the implementation of a mandibular correction. In this case, the dental appliance is therefore a maxillary sub-part of a mandibular correction orthosis. Thus, the first component 1, shown in FIG. 1, can comprise an attachment point, not shown, allowing the articulation of a connecting rod, an elastic element or any connecting element to cooperate with a sub-part. mandibular of a mandibular correction orthosis. Such a fixing point may advantageously be arranged at the level of the unlocking planes 3, in particular on their upper surfaces.

Naturally, the first component 1 can perform other corrective functions than that of correction of the mandibular position, in replacement or in addition, for example an orthodontic type correction. For this, the first part 2 fixed to the dentition can have a corrective action of the individual position of one or more tooth (s) incorrectly positioned (s), according to a conventional orthodontic approach. Thus, a gutter may for example comprise a housing for a tooth slightly offset from the tooth it covers so as to exert a corrective force on the tooth, in a known manner. According to another example, a jack may be arranged at a spacer between its two lateral parts (for example at the level of the palatal bonding surface), which would then be independent and movable relative to each other under the effect of this cylinder, to implement a function of enlargement of the palace (in which case the connecting zone 5 would also be in two parts movable relative to each other). The dental appliance then comprises a second component 10. This second component 10 has the function of correcting the positioning of the patient's tongue. It is in a form similar to a truncated cone portion, to form a curved curvature surface corresponding to the curvature of the maxillary dental arch and extending over substantially 180 degrees. It is also in a form symmetrically arranged around a median plane B-B. One end 15 comprises connecting zones 15, 17 for its connection with the first component 1. In particular, it comprises a rib 16 in the central part, intended for interlocking in the groove 6 of the first component 1. two lateral ends of the notches complementary to the notch of the first component, adapted for their interlocking on this notch. Finally, this second component 10 forms a wall 12 intended to form a stop for maintaining the tongue in a desired volume to correct its positioning.

Naturally, alternatively, the second component 10 could exert a correction function other than that of the positioning of the language. It would then have a modified form adapted to this other correction, comprising for example at least one occlusal unlocking plane. The dental appliance comprising the two assembled components 1, 10 is represented by FIGS. 3 and 4. In this assembly or connection configuration, the respective connection zones of the two components cooperate with one another to ensure the connection of the two components. These two components are thus reliably fixed to avoid their involuntary separation. This attachment remains removable, the connection (or fixation) of the two components 1.10 can be untied by a voluntary action of the patient. According to the embodiment, the connection of the two components is obtained by: - The engagement of the rib 16 of the second component 10 in the groove 6 of the first component 1, in the central and frontal part of the dental appliance; - The interlocking notches of the second connecting zone 17 of the second component 10 in the notches of the second connecting zone 7 of the first component 1, in the lateral and rear part of the dental appliance.

Note that this double bond by at least two different bonding areas provides a reliable connection of the two components. This is important because the second component 10 is not linked to a dental arch but holds in the mouth only by its connection to the first component. It is therefore not a component which cooperates with the first component while being fixed on the other dental arch, but of a component connected to the first component and also disposed at the level of the dental arch on which the first component component in fixed. The two assembled components thus together form a maxillary dental appliance. Alternatively, the connection between the two components could be implemented by any other connecting means. For example, the connection areas may be provided in different numbers, or located differently on the device. In addition, the connection may be different in nature from a socket, for example implementing a clipping, thus comprising an elastic holding effect, or any other type of mechanical connection. According to another variant embodiment, this connection can be obtained by means of a magnetic effect, for example by means of magnets positioned on at least one of the two components and cooperating with a complementary element sensitive to the magnetic field, for example in ferromagnetic material or simply metallic, so that by sufficiently approaching the two components, they remain bound under the effect of the magnetic attraction force.

Thus, the dental appliance can make it possible to perform one or more correction functions, for example mandibular correction as with a specialized orthosis and / or orthodontic correction, day and night, through its first component, and a complementary function, for example repositioning the language, only at night, by adding the second component at night. This therefore forms a modular dental appliance, which can change configuration over time to make several simultaneous corrections possible with the same dental appliance. This solution is very user-friendly for the patient, who can easily bind or loosen the two components of his dental appliance, and choose at any time the most appropriate configuration for its state and / or activity. The invention therefore has the advantage of enabling different corrective functions of a different nature to be performed in a user-friendly manner using the same dental appliance, simply by connecting the two components together or not. In particular, it avoids the use of separate devices to perform these functions or a more restricted use of a single dental appliance. The same device can be used in different configurations, including day and night. In a variant, the same principle can of course be implemented with a dental appliance comprising more than two different components, capable of being releasably connected to one another. The invention also relates to a rapid and low cost method for manufacturing a dental appliance as described above.

The method of producing a dental appliance applies separately to the two components 1, 10, or both components more or less simultaneously, (for this reason we will use the simplified term "appliance" later on term may mean all or part of the dental appliance, including only one or both components of said dental appliance). It is implemented by a system represented by FIG. 8 and comprising the following elements: - an image capture device 31, - a control device 30 and - a manufacturing device 32.

The manufacturing method, illustrated in FIG. 9, comprises a first step E1 for obtaining initial digital data relating to all or part of a dentition of a patient. The step E1 comprises an image capture sub-step E10 during which the image capture device 31 takes digital images IM, (with i = 1, 2, ... N where N is the total number captured images) of all or part of the dentition. The image capture device 31 is advantageously an intraoral camera intended to take images directly inside the patient's mouth. Alternatively, a three-dimensional model of all or part of the dentition of the patient can be manufactured beforehand, in a known manner, by molding made from an impression of the dentition, and then taking digital images of the model using the image capture device.

The image data IM, (with i = 1, 2, ..., N) represent all or part of the dentition of the patient. They are transmitted to the control device 30 and received by the control device 30 during a transmission substep E11. The step E1 for digitizing the dentition and for transmitting initial digital data IM, is followed by a step E2 of virtual 3D representation of all or part of said dentition of the patient, from the initial digital data received (that is i.e. IM image data,). A component of the controller 30 processes the received image data IM, and generates an initial digital data set, denoted DATA0, representing a virtual three-dimensional model MOD0. This model MOD0 represents virtually all or part of the teeth of the patient, and more generally the jaws and the mouth of the patient. It is represented virtually, for example by display on a screen of the control device 30, to allow an operator to view and manipulate it virtually if necessary. The representation step E2 is followed by a step E3 of preparing the correction to be made. For example, the appropriate mandibular advancement range is developed, either from the obtained numerical data and from a virtual representation using the MOD0 model, or directly to the patient himself. As a variant or complement, any other correction, for example orthodontic and / or lingual positioning, can be treated in the same way. This step can be performed in a manner known from the state of the art.

Alternatively, this step E3 may optionally include the development of one or more modifications made virtually on one or more modeled teeth to obtain an orthodontic correction of the dentition. Thus, during step E3, it is possible to create a three-dimensional virtual model MODi of at least a portion of the modified dentition of the patient. This model MOD-ι is defined by a data set DATAv In all cases, these data comprise parameters representing the corrections to be made.

Steps E2 and E3 are executed by a software component of the control device 30. The modified appearance of the mandibular arch and / or teeth is here obtained by virtual manipulation of the mandibular arch and / or teeth, performed by an operator using man-machine interface means 25 of the control device 30. Note that any method of the state of the art for defining the correction can be implemented.

The method continues with a step E4 of producing a digital data file Fi virtually representing the device adapted to the dentition and the mouth of the patient and artificially reproducing the correction envisaged. By the expression "adapted to the dentition of the patient" is meant for example that the first component is adapted to conform to the shape of at least a portion of the teeth of the patient, for, in the embodiment envisaged, allowing a fixing by clipping. In particular, the first part of the first component comprising walls adapted to conform to the shape of one or more patient support teeth, that is to say the gutter, is developed.

Similarly, the second component is developed according to the oral geometry. Preferably, the two components are elaborated at this stage, and in particular their corresponding connection zones. As they are developed from the same virtual data, their coherence between them is ensured.

As a remark, the step E4 implemented in the case of a component to be clipped onto the teeth may comprise several sub-steps, among which: in a sub-step, the digital data representing the occlusal shape of the device at the level of the support teeth, that is to say representing the first part of the gutter type of the first component, are obtained by constructing the negative of a virtual model MOD0 representing all or part of the dentition of the patient, established at the step E2; in another substep, the digital data representing one or the gingival ends of this first part of the first component of the apparatus, vestibular and / or lingual sides, are obtained. A first approach considers the digital data of the virtual model MOD0, representing all or part of the dentition of the patient, and the gingival ends of said first part are established from the ends given by the virtual model. A second approach is to fix average pre-stored tooth heights in an electronic memory for certain categories of teeth, and to base the calculation of the gingival extremities on these average values and the knowledge of the type of tooth considered. The gingival ends of said first portion are calculated to correspond to the actual boundary between the actual dentition and the actual gingiva; another sub-step may make it possible to establish at least one occlusal unlocking plane. For this, the practitioner works advantageously on a virtual representation of the apparatus, established by the two preceding substeps. This representation can be presented on a screen of the control device, via a human machine interface. This representation can be associated with the representation of the real dentition of the patient. Then, the practitioner can choose in a digital library, present on an electronic memory of the control device, one or more unlocking planes formed on particular extension models, and virtually position said extensions and their plans on the first part of the control. 'braces. A software component can assist the practitioner to achieve the ideal overlay of the high and low unlocking planes; another sub-step consists in producing at least one link zone for cooperating with a link zone of another component. In a similar way, the practitioner chooses in a library the linking device which seems to him the most adapted and positions it on the virtual representation still incomplete of the apparatus.

As a remark, the last two sub-steps mentioned above could alternatively be automated, a software component automatically positioning the unlocking planes and / or the binding zones developed from the dentition of the patient, and taking into account the desired correction.

The digital file Fi representing the apparatus Gi therefore contains a set of digital data defining the structure of the apparatus and possibly data useful for the construction of the apparatus Gi. It is determined automatically from the virtual model MOD0 and / or MODi of all or part of the dentition of the patient and correction data, as created in the previous steps. The digital file Fi of the apparatus Gi may also contain instruction data intended to control the manufacture of the apparatus Gi by the manufacturing device 32.

The process then proceeds to a step E5 of manufacturing the apparatus Gi. The manufacturing is carried out by the manufacturing device 32. It can use a manufacturing technique by addition of material, for example by three-dimensional printing. Alternatively, it can use a manufacturing technique by subtraction of material. In this case, the apparatus is for example manufactured by machining a block of material, or laser cutting or jet water.

During the manufacturing step E5, the manufacturing device 32 is controlled by commands obtained from the digital file corresponding to the apparatus to be manufactured. In this case, the controller 30 transmits manufacturing control instructions 32 to the manufacturing device 32 (e.g., 3D printing control instructions or machining control instructions, depending on the technique used). Alternatively, the controller 30 could transmit the file Fi to the manufacturing device. In this case, the manufacturing ordering instructions would be generated from the fi file directly by the manufacturing device.

The material used for the manufacture of the apparatus may be a biocompatible material. It is advantageously recyclable. This allows used devices to be recycled to make new devices.

Thanks to the production of a digital file for the construction of a device, it can be manufactured directly without any intermediate step of realizing a real three-dimensional model of the patient's dentition. Thanks to this, the device can be manufactured in the dentist's office quickly. A single visit to the dentist may even be sufficient to obtain the initial DATA0 data representing the patient's dentition (in whole or in part), then fabricate the device and have it tested to the patient. This approach further ensures the perfect match between the at least two separate components of a dental appliance, the removable connection can be reliably obtained.

The device for controlling the manufacture of an apparatus comprises the following modules: a module 20 for obtaining initial digital data representing all or part of a dentition of a patient, in this case IM image data; ,; a module 21 for creating virtual models MOD0, MODi representing all or part of the patient's dentition, in its real appearance and optionally in a modified appearance in a variant with orthodontic function; a production module 22 able to produce at least one digital data file Fi representing a virtual apparatus Gi suitable for the dentition of the patient 21; an interface 23 for connection with the manufacturing device 32; a control module 24 able to control a device for manufacturing the apparatus, from the digital data file Fi; man-machine interface means 25; a processing and control central unit (CPU) 26, here comprising a microprocessor, to which all the elements 20-25 of the device are connected and intended to control its operation. The invention also relates to a system comprising the image capture device 31, the control device 30 and the manufacturing device 32. The three components 31, 32 and 33 of the system are here separated. The image capture device 31 and the manufacturing device 32 may be connected to the wired or wireless link controller. Alternatively, the image capture device 31 and / or the manufacturing device 32 may be integrated with the controller 30. The invention also relates to a computer program comprising program code instructions for executing the steps of the method previously described when said program is executed by a processing unit, in this case the unit 26.
