DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] 1 shows a schematic representation of a fastening system 100 for dental objects. The fastening system 100 comprises a transverse connecting member 101 for passing through an interdental space 103 and two support elements 105-1 and 105-2 for supporting the transverse connecting member 101 on the sides of the interdental space 103 relative to teeth 107-1, 107-2.

[0024] As the support element 105, a plate element is used which acts as a protector on the facing surfaces of the teeth 107-1 and 107-2 on the lingual and palatal sides. The connection of the inner and outer plate elements is carried out in the interdental space 103 by a round bar made of resin or silicone as the transverse connecting element 101. The transverse connecting element 101 exerts a tension between both support elements 105-1 and 105-2, whereby the fixing system is held on the teeth 107-1 and 107-2. The transverse connecting element 101 and the support elements 105-1 and 105-2 can be made, for example, from a suitable resin material.

[0025] The rod-shaped transverse connecting member 101 has in the longitudinal direction a sawtooth profile 109. The transverse connecting member 101 is guided into the support element 105 through a hole with a defined diameter and is provided with fitting means 111 which are arranged between the teeth and which fit into the sawtooth profile 109 of the transverse connecting member 101. The fitting means 111 can be arranged in an opening 113 into which the transverse connecting member 101 is inserted.

[0026] In that way a fitting mechanism similar to a cable tie is created, which allows for a quick and secure fastening of the fastening system 100 by tensioning. The excess material of the transverse connecting member 101 is cut or trimmed away. The fastening system 100 ensures a secure fastening of the sensor casing.

[0027] However, it is also possible that the rod-shaped transverse connecting member 101 is provided with threads for screwing a nut instead of the sawtooth profile 109. In that case, the nut can be used to fasten the support element 105 to the transverse connecting member 101 or to the dental object. The transverse connecting member 101 with the threads is inserted through an opening 113 in the support element 105-1 or 105-2 and then fixed by a nut which is screwed onto the threads.

[0028] In Fig. 2, a fastening system 100 for a dental sensor 119 as dental object is shown diagrammatically. The dental object can be any three-dimensional object to be placed in the mouth (intraoral cavity). The fastening system 100 comprises two flexible and elastic support elements 105-1 and 105-2, which have an opening 113 with a central fastening means 111. In that way, a pluggable fastening in the form of a cable tie can be realised, in which case the transverse connecting element 101 constitutes a cable tie without a head.

[0029] The support elements 105-1 and 105-2 are resilient such that tension on the transverse connecting member 101 allows the support elements to move into the interdental space 103, thereby creating a clamping effect to improve fixation of the fixation system 100.

[0030] The dental sensor 119 comprises, for example, a casing which is fitted onto a carrier with a light-curable rail material, whereby an adaptation of the casing to the physiological properties of the carrier is achieved in a short time. The casing can be adapted to the corresponding intra-oral situation on the basis of the acquired scan data.

[0031] The dental sensor 119 includes a conduit 131 having a fitting means 111 for fitting within the sawtooth profile 109 of the transverse connecting member 101. When the dental sensor 119 with the conduit 131 is pressed onto the upstanding transverse connecting member 101, it automatically fits onto the sawtooth profile 109 of the transverse connecting member 101. The precise fixation of the dental sensor 119 also allows for overnight wear.

[0032] The fastening system 100 provides the possibility to fasten a dental sensor 119 with a casing as well as electronic circuitry to a tooth inside the mouth. The casing can be press molded from splint material.

[0033] In Fig. 3, another fastening system 100 for dental objects in combination with a dental sensor 119 is shown diagrammatically. A transverse connecting member 101 formed from a silicon bar is fixed to the teeth 107-1 and 107-2 by means of a retainer. To this end, a mobile support element 105 is mounted on the transverse connecting member 101 using a swivel bearing 125 which can rotate by 90°. In that position, the fastening system 100 can slide through the interdental space 103. The swivel bearing 125 between the transverse connecting member 101 and the support element 105 can be formed by a ring element arranged on the transverse connecting member 101 or on the support element 105.

[0034] The support element 105 is then pivoted into a T-shape so that the transverse connecting member 101 can be supported against the teeth 107-1 and 107-2, whereby the sensor 119 is held on the tooth. In that case, the dental sensor 119 can also be attached to the transverse connecting member 101 beforehand on a fastening means and can be detached again in a non-destructive manner.

[0035] In that case, the transverse connecting member 101 can be made tensile elastic and is therefore stretched in such a way that the rotatably supported support element 105 can pivot under the action of a tensile force. Of course, the transverse connecting member 101 can additionally have a length including half the length of the support element 105, so that the pivot bearing mechanism can function to pivot the support element 105. The excess length after pivoting can be removed using the slidable fitting means 111 arranged in the dental sensor 119 or in the pivot bearing 125. The transverse connecting member 101 with the sawtooth profile 109 can thus be rigidly fixed on one side of the surface of the dental sensor 119.

[0036] Another fastening system 100 for dental objects is shown diagrammatically in figure 4. In this embodiment, the transverse connecting member 101 is formed by an elastic belt stretched in the interdental space 103.

[0037] Two elastic wedges are formed on the elastic belt as the support elements 105-1 and 105-2. The support elements 105-1 and 105-2 are formed integrally with the transverse connecting member 101. The first wedge is placed between the two teeth 107-1 and 107-2, the belt is stretched around the tooth 107-2, and the second wedge is fixed between the teeth 107-2 and 107-3. The tension of the belt and the wedges fixes the fastening system 100. In addition, a roughened surface can be provided on the tooth 107-2 to promote additional adhesion.

[0038] 5, another fastening system 100 for dental objects is shown diagrammatically, having a through hole 133 and a channel 135. The through hole 133 is disposed in the transverse connecting member 101, allowing the dental sensor 119 to indirectly perform measurements on the tooth 107.

[0039] Channels 135 formed by suitable V- or U-shaped grooves in the transverse connecting member are provided in the surface of the transverse connecting member 101 to vent the through-holes 133 and to allow for the evacuation of liquids such as saliva. The channels 135 may extend horizontally, diagonally or vertically. The channels 135 may also be provided in the dental sensor and / or in the casing of the dental sensor.

[0040] For example, a vertical channel 135 can be provided which enters the opening 133 from one side and supplies air. Two diagonal channels 135 discharge liquid laterally from the opening 133 to the other side. Of course, it is also possible for multiple conduits 135 to run parallel, entering the opening 133 from one side and exiting it on the other side. Furthermore, multiple conduits 135 can be provided in parallel and diagonal fashion, intersecting in the area of ​​the opening 133.

[0041] Furthermore, the transverse connecting member 101 and both support elements 105-1 and 105-2 are provided with plug-in mechanisms 117, onto which a dental object or a dental sensor 119 can be plugged. The plug-in mechanisms 117 are integrally formed on the transverse connecting member 101 and / or on both support elements 105-1 and 105-2 in the form of protruding engagement means. The engagement function can be achieved by the plug-in mechanisms 117. Thereby, several sensor units can be mounted on the plug-in mechanisms 117 at the same time.

[0042] In Fig. 6 another fastening system 100 for dental objects in combination with a dental sensor 119 is shown diagrammatically. A belt-shaped transverse connecting member 101 with wedge-shaped support elements 105-1 and 105-2 is provided with a plug-in mechanism 117. The plug-in mechanism 117 forms a coupling element for the dental sensor 119 and forms, for example, a knob for a push button. The plug-in mechanism 117 serves to allow the dental sensor 119 to be plugged, inserted or otherwise fixed.

[0043] The surfaces of the individual elements may be roughened on the sides that contact teeth 107-1 and 107-2 to better adhere and prevent slipping on smooth surfaces.

[0044] In Fig. 7 an enlarged view of a fastening system for another dental object is shown. A transverse connecting member 101 is formed by a silicon rod, which is pushed into the interdental space 103 and fixed there. The silicon rod can be stretchable and tensile elastic, so that it thins by stretching. This allows the silicon rod to be easily inserted into the interdental space 103, for example like dental floss.

[0045] A cylindrical silicon rod is provided with a circumferentially protruding support end 115, which is pressed into the opening 113, the opening edge 129 of which is supported against the support end. In this position the transverse connecting member 101 is fixed on the support element 105. In order to be able to easily press the transverse connecting member 101 into the opening 113, the transverse connecting member has a conical section 121, through which the opening edge 129 slides over the support end 115.

[0046] In front of the conical portion 121, the transverse connecting element 101 has a protruding threading portion 123 for threading the transverse connecting element 101 into the opening 113. The threading portion 123 has a sufficient length so that it can be adjusted by shortening it after the fixation of the transverse connecting element 101. In addition, the transverse connecting element 101 has a laterally protruding head portion 127 by means of which pulling forces can be transmitted to the support element 105.

[0047] This method allows the fastening system 100 of the retention dowel principle to be realized, allowing quick and easy fastening of both delicate and voluminous teeth 107-1, 107-2 and 107-3. The fastening system 100 prevents damage to the tooth structure, since the fastening force can be adjusted according to the purpose.

[0048] Furthermore, the resilient silicone rod of the transverse connecting member 101 provides protection against overloading, eliminating the risk of swallowing or aspiration of the fixation system 100. In addition, the soft silicone rod allows for easy cleaning of hidden areas.

[0049] 8 shows a block diagram of a method for fastening a dental object. In step S101, the transverse connecting member 101 is inserted through the interdental space 103. In step S102, the transverse connecting member 101 is supported by the support element 105 for supporting it against the teeth 107-1, 107-2 on the sides of the interdental space 103.

[0050] All the features described and illustrated in relation to individual embodiments of the invention can also be the subject of the invention in various combinations, whereby advantageous simultaneous advantages are achieved.

[0051] All method steps may be performed using apparatus suitable for performing each method step. All functions performed by the feature of interest may be considered as method steps in this method.
