Description

SIX-SIDED BITE BLOCK COMPRISING A FIRST SIDE ARRANGED WITH AN ADHESIVE

Technical field

[0001] The present invention relates to dental equipment for use in a patient's mouth during dental procedures, particularly to a bite block which is arranged to carry at least one other type of dental equipment, such as a device which absorb saliva, for example an absorption pad.

Technical background

[0002] To steady a patient's jaw and to maintain the mouth of the patient in an open condition as well as to improve access and visibility during dental procedures, devices known as bite blocks are positioned inside a patient's mouth, between the teeth of the upper and lower jaw. Bite blocks are often made of rather stiff, but still resilient material, to be able to both support the jaws to stay in an open position and to provide comfort. The resilient “behavior” is important since it is uncomfortable to bite on a too hard material and the surface of the teeth may be damaged. Further, the resilient property also provides a better “grip” wherein the bite block stays in position in a better way, and it is more comfortable for the patient.

[0003] The design and the resilient properties of known bite blocks varies a lot and also other properties may be of importance when designing bite blocks, such as the need of combine a bite block with other dental equipment. To reduce the number of dental tools inside the mouth and to ease the work for the dentist, bite blocks may be designed to carry other tools. One example of such a solution is found in US 2009/0017416 A1 , where a V-shaped bite block comprises a holder, embedded in the bite block, and a light source attached to an insert which is to be positioned into the holder. This document focuses on an illuminator system for dental use, where a number of other combinations of dental equipment are combined with a light source. One problem with this solution is that the different dental equipment is to be specially designed to fit into the holder of the bite block. [0004] Another solution for combination of a bite block and a function of fluid absorption, is presented in US 6,634,884 B2, where a fluid absorbing bite block is presented. The bite block comprises a generally wedge-shaped shell in which an absorbent core is contained. The core is constructed of cotton or other known absorbent material. The shell is constructed of a material which is rigid enough to hold a mouth of a patient in an open position when the bite block is inserted within the mouth, for example, foamed polystyrene and is designed with peaks and valleys, for providing a gripping surface for the teeth of the patient. The core spans completely between first and second sides of the shell and contains as mentioned some kind of absorbent. When using just an ordinary bite block, which does not absorb saliva, saliva must be routinely suctioned from around the bite block during the dental procedure by a suction tool or by placing for example a cotton roll or the like in the mouth, between the cheek and gums and between the tongue and gums, to help absorb saliva. The problem is that these cotton rolls often become dislodged, interfering with the procedure, and triggering the gag reflex in the patient. Compared to ordinary bite blocks, the above-described combined bite block solves the problem by placing cotton or other absorbent material in a holder (the core), wherein a combined bite block function and space-saving salivaabsorbing function is achieved. One problem with this solution is that the absorbent must be possible to fit into the core of the bite block.

[0005] Another solution relating to the combination of a bite block function and other different dental equipment is presented in US 10,952,707 B2. According to this invention, a number of different tools for dental use may be combined in a more universal way, by that a U-shaped bite block comprises a magnet embedded in a central portion of the U-shaped mounting base, proximate an accessory mount. The dental accessory comprises corresponding magnetic accessory mount which is detachably coupled with bite block by magnetic interaction with the magnet of the bite block. One problem with this solution is that the design drives cost and further that small parts, like magnets etc., accidentally may loosen with a risk of the patient swallowing them. Summary of the invention

[0006] One object of the present invention is to provide a bite block which solves the above-described problems, which are solved by a bite block according to the independent claim 1 .

[0007] According to an aspect, a bite block for dental use is disclosed. In a using position of the bite block, the bite block is positioned between an upper row of teeth and a lower row of teeth on one side of a patient’s mouth, (a first side) and is arranged for supporting an open position of the mouth. Referring to the using position of the bite block, the bite block comprises a first block side facing a cheek of the first side of the mouth, a second block side opposite the first block side and facing an oral cavity of the mouth, a third block side facing the upper row of teeth of the mouth, a fourth block side opposite the third block side and facing the lower row of teeth of the mouth, a fifth block side facing an opening of the mouth and finally a sixth block side opposite the fifth side and facing a throat opening of the mouth. Further, the bite block comprises an adhesive arranged on the first block side of the bite block. The adhesive may be in any form, for example a sticky tape, glue or the like. The third and fourth block sides described above are not “fixed” to face the upper respective the lower row of teeth, since the bite block preferably is mirror-symmetrical, why the third block side may face the upper or lower row of teeth, depending on which side of the mouth the bite block is positioned in. The same applies to the fourth block side which may face the upper or lower row of teeth, depending on which side of the mouth the bite block is positioned in. By that, the bite block preferably is reversible. Such bite block may be used to combine the bite block with another dental tool or dental equipment, independently of the type of dental equipment to be used. The dental equipment only has to fit at least a part of the adhesive area of the bite block, to be able to be combined with the bite block. Preferably, the bite block is produced in a very light material, like styrofoam or the like, which provides better comfort for the patient as well as positive environmental aspects. Known bite blocks are kept in position by means of ramps/protruding walls on each side of the long sides of the row of teeth, in the upper and lower jaw, respectively. The patient must open the mouth in a maximized position for the bite block to be kept in a stable position between the row of teeth, which may be very uncomfortable for the patient due to tensions in the jaw muscles.

[0008] According to an embodiment, the adhesive comprises an adhesive cover, arranged to cover the adhesive of the bite block and further arranged to be removed from the adhesive for exposing the adhesive. The adhesive cover may be in the form of peelable protective paper cover or the like. The bite block may thereby be delivered to an end consumer (dentist) with the adhesive cover mounted on top of the adhesive, wherein the dentist or any other person, may peel off the cover from the bite block, if the bite block is to be combined with another dental tool/equipment. After this, the bite block may be mounted to the other dental tool/equipment.

[0009] According to an embodiment, the bite block further comprises an absorption pad, which comprises a first pad side, which in the using position faces the cheek of the first side of a patient’s mouth, and an opposite second pad side, which in the using position faces the oral cavity of the mouth. Further, the absorption pad is arranged to be fixedly arranged with its second pad side to the adhesive of the bite block. By that the bite block is produced as one piece and thus may be delivered with or without an absorption pad to for example a dentist, a flexible and cheap product is achieved. The bite block thereby is easily combined by the end user (dentist) or pre-assembled to a complete product, with the bite block function and the saliva absorption function. Thus, the bite block may be delivered in a space saving way by not having the absorption pad attached to it from the start (if wanted) and at the dentist, the bite block is combined with a standard absorption pad, which normally is at hand at the dentist facility. The adsorption pad preferably comprises a first thin and soft permeable layer at the first side, which first layer is arranged to adhere to the inner side of the cheek, preferably at the cheek mucosa, and a second non-permeable layer at the second side, which by that do not absorb saliva. Further, between the first and second layers is an intermediate third layer of gel granules arranged, which third layer binds and retains saliva. By that the absorption pad adheres to the inner side of the cheek/the cheek mucosa, also the bite block is securely held in position in the mouth. And further, if the bite block is made in a very light material (for example styrofoam), it easily stays in position in the mouth, only by the fixed attachment to the absorption pad which in turn adheres to the cheek mucosa, wherein the bite block is held in position, by means of the absorption pad.

[0010] By that the bite block is attached to the absorption pad, which in the using position adheres to the cheek mucosa, the bite block does not need to be positioned in an innermost position (corresponding to a maximal opening of the mouth) like known bite blocks. Instead, the bite block is positioned in a more comfortable position which does not correspond to the maximal opening of the mouth, why a higher comfort for the patient is obtained. Known bite blocks cannot be moved during patient treatment in such an easy manner as the inventive bite block, due to for example protruding edges/walls enclosing edges of the teeth. Instead, they block the space and visibility due to their design, when for example an assistant nurse or a dentist needs to perform different actions, since they are not easily moved in direction towards/from the cheek. Sometimes, when for example an extra vacuum suction tool is needed, the inventive bite block with absorption pad can easily be moved sideways with the help of for example a mouth mirror, since the bite block has flat surfaces and is attached to the cheek. The patient only needs to open the mouth a little, when the bite complete bite block needs to be moved, and then it returns to its original position when the mouth mirror is relieved, due to the natural pressure force from the cheek.

[0011 ] According to an embodiment, the bite block further comprises a protection cover, arranged to cover at least the second, third, fourth, fifth and sixth bite block sides of the bite block. This means that all surfaces/block sides of the bite block, except the first block side with the adhesive, comprises the protection cover. The protection cover may be needed to enclose the bite block material, which may be sensitive depending on the material, for example if a cost-effective styrofoam material is used as bite block material. The protection cover may also comprise other characteristics, such as comprising friction-related properties, protection against damaging the bite block material (if sensitive for example at high pressure biting), non-permeable material etc. [0012] According to an embodiment, the protection cover further is arranged to cover at least parts of exposed parts of the second side of the absorption pad, which exposed parts are located outside the bite block, when the absorption pad is fixedly arranged with the second side to the adhesive of the bite block. This means that when the absorption pad is attached to the bite block, the cover encloses the remaining block sides (all but the first block side) as well as the parts of the second side of the absorption pad, which are “visible” from the bite block side, so to speak, outside the bite block. The protection cover preferably is arranged as one continuous cover which encloses the bite block and further the outer surfaces of the second side of the absorption pad, that is, as one protection cover unit. The protection cover may stretch out completely to an outer edge of the absorption pad, or stop just before the outer edge, wherein an outermost edge part of the second side of the absorption pad is a kind of “transition area” between the protection cover and the second side of the absorption pad. Alternatively, the protection cover may reach over the outer edge and further a short distance over an outer edge of the first side of the absorption pad, to just enclose the edge but leave a substantial area of the absorption area of the first side of the absorption pad free for absorption. If the combined bite block with absorption pad comprises a protection cover, the complete product normally is produced like that and is delivered as one complete product to the dentist. The protection cover provides an extra safety for the product such that no small parts may be swallowed by mistake, if the product is damaged somehow.

[0013] According to an embodiment, the absorption pad comprises a through hole at an outer edge of the absorption pad. This through hole is arranged for a dental floss, mainly for safety reasons, but also, after releasing the absorption pad from the cheek mucosa with water, for easy removal of the bite block with the absorption pad from the mouth. If a protection cover is used, the hole is arranged also through the protection cover.

[0014] According to an embodiment, the fifth block side of the bite block is longer compared to the sixth block side of the bite block, wherein the third block side and fourth block side of the bite block are inclined toward each other in direction from the fifth block side towards the sixth block side of the bite block. This provides a “V-shaped” bite block which corresponds to the slope of the occlusion plane (plane of the bite surface) and the angle between the upper and lower jaw, which gives maximum contact surface between the teeth and the block and thus a good holding of the bite block in position between the jaws. This provides best comfort for the patient.

[0015] According to an embodiment, the bite block comprises resilient material. At least parts of the bite block may be resilient, preferably at least the surfaces which faces the teeth, which is the third and fourth block sides. The bite block may also be completely resilient, comprising one or more resilient materials. A bite block material with resilient properties provides improved comfort for the patient and resilient surface material provides not only comfort but also a better grip (higher friction) of the bite block between the upper and lower row of teeth, wherein the bite block is kept in place in a more secure manner.

[0016] According to an embodiment, the bite block is made of styrofoam. Styrofoam may also be known as frigolite or foam polystyrene. This material is very cost-effective to use and serves well as the product normally is used only one time, and then is discarded or recycled. Further, this kind of material is light, which is good in combination with an absorption pad as explained above (to keep the bite block in position via the absorption pad). The intended styrofoam is free from dangerous substances and is approved to use inside a mouth. Known bite blocks are expensive and heavy compared to a bite block of styrofoam. The bite block may alternatively be made of a non-oil-based material, for example a more environmentally friendly material like paper-based material or the like.

[0017] According to an embodiment, a distance between the first block side and the second block side of the bite block (i.e. the height of the bite block in direction from the cheek towards the oral cavity) is between 5 - 20 mm, preferably between 8 - 16 mm. This span is important to meet to meet differences between the thickness of teeth as well as the size of the oral cavity, why it is positive to have a variation of the height of the bite block. Thus, the height is adopted depending on the width of the teeth and available space in the oral cavity. For example, bite block standard sizes may be produced and delivered in for example 2-4 sizes or the like, wherein also the size of the bite block (not only the height) may be varied, for example, the length of the fifth and sixth block side etc.

[0018] One embodiment may be that the bite block comprises an absorbent core arranged into a bite block frame, wherein the bite block may have an absorbing function itself or as a complement to the absorption pad.

Description of embodiments

[0024] In the following, a detailed description of a preferred embodiment of a bite block according to the invention is described with reference to the accompanying figures. The invention is not limited to the figures.

[0025] Fig. 1 a shows an isometric view of a bite block 10 which is intended to be used as a support for keeping a patient’s mouth in an open position during dental care, dental surgery, scanning or the like. The bite block 10 is to be positioned between an upper row of teeth 31 and a lower row of teeth 32 on a first side of the patient’s mouth (see further Fig. 4). The bite block 10 comprises a first block side 11 , which in a using position in a mouth faces a cheek of a first side of the mouth. Opposite the first block side 11 is a second block side 12 arranged, thus facing an oral cavity of the mouth in the using position. A third block side 13 of the bite block 10 is arranged to face the upper row of teeth 31 of the mouth (or the lower, depending on which side of the mouth the bite block is positioned) and a fourth block side 14 is arranged opposite the third block side 13 and thus is arranged to face the lower row of teeth 32 of the mouth (or upper, depending on which side of the mouth the bite block is positioned). Further, the bite block 10 comprises a fifth block side 15 which faces an opening of the mouth, in the using position, and a sixth block side 16, which is arranged opposite the fifth side 15 and thus faces a throat opening of the mouth. The bite block 10 further comprises an adhesive 17, which is arranged on the first block side 11 of the bite block 10. The adhesive 17 is arranged for attachment of the bite block 10 to another dental equipment, for example an absorption pad, another bite block, or other types of dental equipment. The adhesive 17 is covered by an adhesive cover 18, which is arranged to cover the adhesive 17 during the time before it is mounted to another dental object, and it is further arranged to be removed from the adhesive 17, for exposing the adhesive 17, when to be used for attaching the bite block 10 to an object. The function of the bite block 10 is as support for assisting a patient to keep the mouth open during dental care in the mouth. The bite block 10 is cut out, or in any other way shaped, to its preferred form, wherein the adhesive 17 is attached to the first block side 11 of the bite block 10. The adhesive cover 18 preferably is attached on the adhesive from one side as a protection in connection to the application of the adhesive 17 on the first block side 11 . The adhesive 17 including the adhesive cover 18 may be pre-cut or cut out (shaped) in the same step as the shaping of the bite block, the latter for example by attaching the adhesive layer 17 and the adhesive cover 18 on a large piece of material from which the bite blocks 10 are to be cut out, for example a large piece of styrofoam, whereafter the bite blocks 10 are cut out at the same time as cutting out the adhesive 17 and adhesive cover 18. Of course, the bite blocks 10 may be cut out first, and then provided with adhesive 17 and adhesive cover 18, one and one.

[0026] The bite block 10 preferably is V-shaped, wherein the fifth block side 15 of the bite block 10 is longer compared to the sixth block side 16 of the bite block 10. By that, the third block side 13 and fourth block side 14 of the bite block 10 are inclined toward each other in direction from the fifth block side 15 towards the sixth block side 16, wherein the bite block 10 expands in the opposite direction, from the throat towards the opening of the mouth, relating to the using position of the bite block 10 in a mouth. The height of the bite block 10, that is a distance between the first block side 11 and the second block side 12 of the bite block 10, must fit different users and that height may preferably be between 5 - 20 mm, and more preferred between 8 - 16 mm. Further, the bite block 10 is resilient, which means that it is possible to compress it a little bit (not too much which may affect the support function), which increases the comfort for the user, since it is uncomfortable to bite on hard material. A preferred material of the bite block 10 is for example styrofoam or a similar material, which may be stiff enough to support but still with resilient characteristics for comfort and for enhanced “grip-function” between the rows of teeth, which also is received with resilient material. Of course, the bite block 10 may have a stiffer core, with a less stiff (more resilient) surface, or the opposite.

[0027] Fig 1 b shows an isometric view of the bite block 10 when about to be attached to an absorption pad 20. The absorption pad 20 comprises a first pad side 21 , which in the using position faces the cheek of the first side of a patient’s mouth, and an opposite second pad side 22, which in the using position faces the oral cavity of the mouth. Further, the absorption pad 20 is arranged to be fixedly arranged with its second pad side 22 to the adhesive 17 of the bite block 10. The adsorption pad 20 preferably comprises three layers, a first thin and soft permeable layer at the first side 21 , which first layer is arranged to adhere to the inner side of the cheek at the cheek mucosa, and a second non-permeable layer at the second side 22, which by that do not absorb saliva. Further, between the first and second layers is an intermediate third layer of gel granules (or the like) arranged, which third layer binds and retains absorbed saliva. The absorption pad 20 preferably comprises a through hole 23 arranged at an outer edge 24 of the absorption pad 20. This through hole 23 is arranged for a dental floss, for extra safety if a patient accidentally begins to swallow the product. It is also convenient for the dentist, after removing the absorption pad 20 from the cheek mucosa with water, to remove the complete product from the mouth. If a protection cover is used (see below), the through hole 23 is arranged also through the protection cover.

[0028] Compared to Fig. 1a, the bite block 10 is flipped around such that the first side 11 faces the absorption pad 20. First, the adhesive cover 18 is removed from the adhesive 17 on the first block side 11 of the bite block 10, whereafter the bite block 10 and the absorption pad 20 are brought together to form a combined product 40, comprising the bite block 10 and the absorption pad 20. The combined product 40 is arranged both for support to keep a mouth open - the bite block function - as well as for absorbing saliva, mainly from a patient’s cheek mucosa (glandula parotis) - the absorption pad function.

[0029] Fig. 1 c shows an isometric view of the combined product 40, where the bite block 10 is attached to the absorption pad 20. The bite block 10 is preferably centrally arranged on the second pad side 22 of the absorption pad 20 such that parts of the second pad side 22 are visible/are arranged outside the bite block 10.

[0030] Fig. 2a shows the combined product 40 (with the bite block 10 and absorption pad 20) of Fig. 1c in a view from above and Fig. 2b shows the combined product 40 obliquely from below. The combined product 40 is, in the same way as the bite block 10 and the absorption pad 20, mirror-symmetrical, which means that it is possible to use the same combined product 40 on both sides of the mouth, and therefore there is no need of a “left or right side” product. This is obvious when studying Fig. 2a. The absorption pad 20 preferably is a standard pad with known design, like in the figures, where the arrow-like design visualizes the insert direction. The preferred absorption pad 20 has an “arrowhead” arranged to be positioned at the cheek closest to the throat, and with an opposite side designed like an “arrow-end”, which is arranged to be positioned at the cheek closest to the opening of the mouth. As mentioned before, the bite block 10 is positioned centrally at the second side 22 of the absorption pad 20, with the sixth block side 16 closest to the “arrow-head” of the absorption pad 20 and the fifth block side 15 closest to the “arrow-end” of the absorption pad 20. The first pad side 21 faces away from the bite block 10 and is as mentioned before arranged for absorbing saliva and further arranged to attach to the cheek due to its special characteristics.

[0031] Fig. 3 shows an isometric view of an alternative and surface-protected combined unit 50 comprising the bite block 10 and the absorption pad 20 and further a protection cover 19. The bite block 10, the absorption pad 20 and the protection cover 19 forms the alternative and surface-protected combined unit 50. The protection cover 19 is arranged to cover the second, third, fourth, fifth and sixth bite block sides 12, 13, 14, 15, 16 of the bite block 10 as well as to cover the exposed parts of the second side 22 of the absorption pad 20. The referred exposed parts of the absorption pad 20 are located outside the bite block 10, when the absorption pad 20 is fixedly arranged with the second side 22 to the adhesive 17 of the first side 11 of the bite block 10. When the absorption pad 20 is attached to the bite block 10, the protection cover 19 encloses the remaining block sides (all but the first block side) as well as the parts of the second side 22 of the absorption pad 20, which are “visible” so to speak, outside the bite block 10. The protection cover 19 is arranged as a continuous cover which preferably reaches over the bite block 10 and the remaining parts of the second pad side 22, out to an outer edge of the absorption pad 20. Another option may be that the protection cover 19 ends just before the outer edge of the absorption pad 20, wherein an outermost edge part of the second pad side 22 of the absorption pad 20 is a kind of “transition area” between the protection cover 19 and the second side 22 of the absorption pad 20. Yet another alternative may be that the protection cover 19 may reach over the outer edge of the absorption pad and further a short distance over an outer edge of the first side 21 of the absorption pad 20. The surface protected combined bite block 50 normally is produced like a complete unit including the three main parts, bite block 10, absorption pad 20 and protection cover 19, and is delivered as one complete product 40, 50 to the dentist. The protection cover 19 provides an extra safety for the product such that no small parts may be swallowed by mistake, if the product is damaged somehow. If the absorption pad 20 comprises the through hole 23 at the outer edge 24, the through hole 23 is arranged also through the protection cover 19.

[0032] Fig. 4 shows an isometric view of the combined product 40 with the bite block 10 and absorption pad 20, when positioned between an upper row of teeth 31 and a lower row of teeth 32, on one side of a patient’s mouth, in this case the right side of the mouth. The third block side 13 faces the upper row of teeth 31 and the fourth block side 14 face the lower row of teeth 32 in the using position (on the right side of the mouth). In the using position, the bite block 10 is clamped between the upper and lower row of teeth 31 , 32 wherein the third block side 13 of the bite block 10 engages with the upper row of teeth 31 , and the fourth block side 14 engages with the lower row of teeth 32. If the combined product 40 is arranged on the opposite side of the mouth, the left side of the mouth, the combined product 40 is turned 180°, wherein the third block side 13 of the bite block 10 engages with the lower row of teeth 32, and the fourth block side 14 engages with the upper row of teeth 31 . The fifth block side 15 is always intended to face the mouth opening in the using position, and the opposite sixth block side 16 is always intended to face the throat. The first pad side 21 (not visible) of the absorption pad 20 is intended to be in contact with the inside of the cheek and the second pad side 22 of the absorption pad 20 as well as the second block side 12 of the bite block 10 is intended to always face the oral cavity of the mouth.
