Abstract

A dental appliance comprising: a tongue support element (1) with a trough (2) for the tongue, the trough having a concave inner surface and a convex outer surface; a tooth support element (3) with an upper and a lower bite surface (4a, 4b), which are arranged on the outer surface side of the tongue trough (2) so that the upper bite surface (4a) coincides with the lower bite surface (4b), only on an opposite side of the tongue trough (2), and so that a first end (5) of the inner surface of the tongue trough is between the upper and the lower bite surfaces (4a, 4b) of the tooth support element (3). The inner surface (6) of the tongue trough is directed sideways in relation to the tooth support element (3), the inner surface (6) of the tongue trough being arranged to receive a patient's tongue and to position it to a side of the oral cavity, partly between the bite surfaces (4a, 4b).

DETAILED DESCRIPTION

[0023] FIG. 1 shows schematically a tooth and tongue support from an inner surface side of a tongue trough, FIG. 2 from the front, FIG. 3 from above, and FIG. 4 as a diagonal rear perspective view from below.

[0024] The tooth and tongue support 100 is preferably made of one and the same piece of material, which is preferably made of a resilient material, such as plastic or elastomer or a mixture containing these. The manufacturing material may comprise e.g. thermoset or thermoplastic, such as polyolefin, e.g. polypropylene, and/or material marketed under trade name Dryflex.

[0025] The tooth and tongue support 100 may be disposable or reusable after disinfection. According to another idea, the tooth and tongue support 100 may be made of two or more parts to be connected together, the manufacturing materials of which may be the same or differ from another.

[0026] Because of its resilience, the tooth and tongue support 100 may be arranged according to personal features of the mouth to an optimal position in the oral cavity. Moreover, the resilient material is pleasant to the patient.

[0027] The tooth and tongue support 100 comprises a tongue support element 1 with a trough 2 for the tongue, the trough having a concave inner surface and a convex outer surface, and a tooth support element 3 with an upper and a lower bite surface 4a, 4b.

[0028] Said bite surfaces 4a, 4b are arranged to the convex outer surface of the tongue trough 2 so that the upper bite surface 4a coincides with the lower bite surface 4b, only on an opposite side of the tongue trough 2.

[0029] The inner surface 6 of the tongue trough is directed sideways in relation to the tooth support element 3. A first end 5 of the inner surface 5 of the tongue trough is between the upper and the lower bite surfaces 4a, 4b of the tooth support element 3, which feature further enhances resilience between the bite surfaces 4a, 4b. A second end 15 of the inner surface 6 of the tongue trough extends to a distance from the first end 5 that allows the patient's tongue to be substantially entirely covered by the tongue trough 2.

[0030] The concave inner surface 6 of the tongue trough receives the patient's tongue and positions it to one side of the oral cavity, partly between the bite surfaces 4a, 4b.

[0031] As seen in FIG. 1, a lower portion 9 of the tongue trough 2 extends past level L of the bite surface 4b, i.e. below it. It is thus possible to preferably arrange the lower portion 9 against the floor of the oral cavity and/or against the gums of the lower teeth so as to make sure that the tongue does not escape from the space reserved for it by passing under the tongue trough 2.

[0032] The dimensioning of the tooth and tongue support 100 and the details of its design have been advantageously selected in accordance with the specific features of the oral cavity to make it suitable for the oral cavity of most patients. However, due to natural variation in the shapes and sizes of oral cavities, a series of tooth and tongue supports 100 of different sizes and shapes may be provided. According to another idea, the tooth and tongue support 100 is tailor-made according to measurements taken from the patient's oral cavity.

[0033] The tooth and tongue support 100 shown in the figure is asymmetric so that it may be used on the right side of the oral cavity. In that case the tooth and tongue support 100 positions the tongue to the left side of the oral cavity, partly between the left upper and lower teeth as a result of which ample space for treatment is left on the right side and the front part of the oral cavity. Due to the asymmetry, a separate tooth and tongue support 100 may be made for treatment to be carried out on the left side of the oral cavity, which support may be a mirror image of the tooth and tongue support 100 shown in the figure.

[0034] The bite surface 4a, 4b may have a basic shape that is convexly curved in its longitudinal direction. A curved basic shape may help to arrange the support 100 to an optimal position in the oral cavity. However, said curvature is not indispensable: the bite surface 4a, 4b may be at least substantially straight, for example.

[0035] In the figures the bite surface 4a, 4b comprises protrusions 7 arranged in a transverse direction. With the protrusions 7 the support 100 may stay in place better. There are naturally also other ways of arranging the protrusions 7, for example in a longitudinal direction of the bite surface 4a, 4b, or they may be left out altogether.

[0036] The bite surface 4a, 4b shown in the figures comprises a raised edge portion 8 on both sides thereof. This reduces, among other things, the possibility of the bite surface 4a, 4b from slipping away from between the teeth.

[0037] The tooth and tongue support 100 shown in the figures has a suction channel connector 10 arranged to the tongue support element 1, to which connector a suction tube 11 may be fastened. It should be noted at this point that the tooth and tongue support 100 may also be implemented without the suction channel connector 10.

[0038] During treatment, such as filling of a tooth, carried out in the oral cavity, fluids, such as saliva and/or water, collect into the oral cavity. The fluids must be evacuated from time to time so that the patient would not feel uncomfortable or to keep dry the area under treatment. It is known in the art to use a suction tube 11 for this purpose.

[0039] The tooth and tongue support 100 shown in the figures further comprises a suction trough 12 arranged into the tongue trough and forming a recess 13 that sets on the outer surface side of the tongue trough 2. The suction trough 12 preferably has a resilient structure so that it may be positioned in an optimal manner to the oral cavity according to the patient's individual features.

[0040] Fluids collecting into the oral cavity collect into the suction trough 12 and its recess 13. The suction channel connector 10 is arranged to be in connection with said recess 13 so that fluids collecting into the recess 13 may be evacuated through the suction tube 11. According to an idea, the suction tube 11 may be arranged to the recess 13 by means of the suction channel connector 10. According to another idea, the suction channel connector 10 reaches the recess 13, in which case the suction tube 11 does not necessarily need to be extended all the way to the recess 13.

[0041] According to an idea, the inner surface of the suction trough 12 comprises one or more grooves 14 connecting with said recess 13. The groove 14 enhances the flow of fluids to be removed into the recess 13 especially when fluids collect slowly in the suction trough 12. With the arrangement described here it is possible to direct the suction to the lowermost point of the suction trough 12, i.e. to the point where the fluids naturally flow.

[0042] However, it should be noted that the tooth and tongue support 100 may also be implemented without the suction trough 11.

[0043] In some cases, features disclosed in this application may be used as such, regardless of other features. On the other hand, when necessary, features disclosed in this application may be combined in order to provide different combinations.

[0044] The drawings and related disclosure are only intended to illustrate the inventive idea. It will be apparent to a person skilled in the art that the invention is not restricted to the above-described embodiments disclosing the invention through some examples, but various modifications and different applications of the invention are feasible within the inventive idea defined in the accompanying claims.
