Definitions

• the present invention relates to oral apparatus and in particular, though not necessarily, oral apparatus for use during sporting activities.
• Mouthguards are commonly used in sports to protect a user's teeth and associated structures (such as the dental arches, and upper and lower jaws) from injury as a result of a force being applied to the mouth.
• Mouthguards commonly available today fall within one of three categories: the stock mouthguard which is supplied to the user in the form in which it is to be used; self- mouldable mouthguards which can be moulded by the user so that the inside of the mouthguard adapts to the shape of the user's teeth; and custom mouthguards which are moulded by a professional to suit the characteristics of the user.
• WO 2009/012243 describes a mouthguard which reduces the pressure at the temporomandibular joint as the user bites onto the mouthguard thereby reducing the amount of a stress hormone released by a user using the apparatus.
• a kit comprising oral apparatus including at least one bite portion configured to receive a pad and a plurality of pads, each pad being configured to attach to the at least one bite portion wherein at least two of the plurality of pads have different depths.
• oral apparatus including at least one bite portion configured to receive a pad and a plurality of pads, each pad being configured to attach to the at least one bite portion wherein at least two of the plurality of pads have different depths.
• the distance that the pads maintain between the teeth of the upper and lower jaw of a user may be varied by changing the depth of the pads attached to the bite portion enabling an optimal depth to be selected for the user.
• the oral apparatus is configured such that, when inserted into a user's mouth, the bite pad is sited between the teeth of the upper and lower jaw of the user.
• the bite portion is removably connectable to a pad.
• different pads may be selected depending on the activity to be undertaken by a user. Also it enables experimentation to determine the optimal depth of pad to be used for an activity.
• the depth of a pad may be between 1 and 12mm.
• the bite portion may be provided with an attachment means and each of the pads is provided with complementary attachment means.
• one of the attachment means and complementary attachments means comprises a female member and the other of the attachment means and complementary attachments means comprises a male member.
• the female and male member may be held in frictional engagement or comprise a complementary thread attachment or the male member includes an enlarged head receivable within a chamber of the female member.
• the oral apparatus further comprises a restriction means situated, such that, when inserted into the user's mouth the restriction means is situated between the user's teeth and buccal mucosa, the restriction means extending past the depth of a pad when attached to the bite portion.
• This restriction means reduces the spread or lateral movement of the pad when it is depressed by a user's teeth by forming a physical barrier to the spread. This means that the depth of the pad is not significantly altered in use and/or stops the pad moving from between the teeth into the space between the teeth and the buccal mucosa.
• the oral apparatus may be a mouthguard and the bite portion may form part of the base or part of a side wall of the mouthguard. Where the bite portion forms part of a side wall of the mouthguard the pads may have an L-shaped cross-section.
• the oral apparatus and bite pads may be made from one or more of the group comprising silicon, TPE or EVA.
• a kit comprising a plurality of pads, each pad being configured to attach to a bite portion of an oral apparatus wherein at least two of the plurality of pads have different depths.
• a kit comprising two or more oral apparatuses each apparatus including at least one bite pad the bite pad of each apparatus having a different depth to the bite pad of the other apparatuses. This enables a user to determine an optimal depth of bite pad for an activity and select an oral apparatus for future use in the activity.
• Each oral apparatus may be configured such that, when inserted into a user's mouth, the bite pad situated between the molar teeth of the upper and lower jaw of the user.
• the depth of a bite pad is preferably between 1 and 12mm.
• the oral apparatus further comprises a restriction means situated, such that, when inserted into the user's mouth the restriction means is situated between the user's teeth and buccal mucosa, the restriction means extending past the depth of a pad when attached to the bite portion.
• the presence of this restriction means reduces the spread or lateral movement of the pad when it is depressed by a user's teeth by forming a physical barrier to the spread. This means that the depth of the pad is not significantly altered in use and/or stops the pad moving from between the teeth into the space between the teeth and the buccal mucosa.
• the oral apparatus may comprise a mouthguard and the bite pad forms part of the base of the mouthguard.
• the oral apparatuses may be made from one or more of the group comprising silicon, TPE or EVA.

• Figure 15 illustrates a pad for attachment to a mouthguard in accordance with a further embodiment of the present invention.
• FIGS 1 to 4 illustrate a support member 12 of an apparatus in accordance with the present invention.
• the support member 12 has two plates 14 connected by an integral connecting portion 13.
• the plates 14 are positioned relative to each other so that when the oral apparatus is inserted into a mouth they sit between molars in the mouth.
• the connecting portion maintains the relative positioning of the two plates 14.
• the connecting portion 13 has a substantially semi-circular shape.
• the connecting portion 13 is also on a substantially lower plane than the receiving portions 14 when the device 10 is oriented for use.
• the connecting portion 13 includes sloping parts. This enables the connecting portion to run around the gumline of the user when the oral apparatus is inserted into a mouth and provide minimal interference to the user.
• the connecting portion may take any suitable form.
• the connecting portion may be a plate configured to be substantially in contact with the roof of a mouth when the oral apparatus is inserted into the mouth.

• the pads may connect to each other in any suitable way.
• the upper pad may be provided with one or more male members and the lower pad may be provided with one or more complementary female members such that the upper and lower pads are held in communication with one either side of the plate.
• the upper pad may be provided with one or more female members and the lower pad may be provided with one or more complementary male members. In this way pads can be attached to be present above and below the receiving portion 14.
• the support member 12 may be made from any suitable material.
• the plates 14 are more resilient than the pads in order to help the pads maintain their shape and additionally help the distance between the teeth of the upper and lower jaw to be maintained.
• FIG. 5a to 5d show how the performance of a user performing four different activities differs with separation distance.
• the same separation distance may result in different performance effects in same user depending on the activity that is being undertaken.
• the optimal separation distance may be different for different users performing the same activity. Namely, the optimal separation distance is dependent on the user and the activity.
• the separation distance which is optimal for a user performing a particular activity is achieved using the above device by the user measuring their performance at an activity. For example, if the user is a weightlifter the measure of their performance may be the amount of weight they can lift in their chosen competitive discipline, the more weight they can lift the better their performance.
• the apparatus with a first set of upper and lower pads attached to each plate is then inserted into the user's mouth and the user's performance at the activity remeasured.
• the separation distance maintained by the oral apparatus may be further varied using pads of different depths and measuring the user's performance at the activity at each separation distance.
• the user can compare their performance at different separation distances. The user can then determine the depth of pads required to provide them with optimal performance and will know to use this depth when performing this activity in future. If the user wishes to carry out more than one activity then they can vary the depth of the pads attached to the plates according to the activity. This allows a user to achieve optimal performance in both activities whilst only requiring one apparatus.
• the pads to be removeably attached to the plates 14 of the device pads of different depth sizes may be selected. This allows the separation distance to be optimised for each user without requiring separate custom devices to be manufactured for each user.

• the pads 16 may be provided above or below the plate surface when the apparatus is in use.
• the plate may form the pad and have a depth d.
• the user is provided with multiple apparatus each having a different depth d. The user can then perform the same method to determine the optimal separation distance for an activity as described above. However, rather than alternating the pads they can measure the performance achieved with each apparatus and determine the apparatus which provides them with the optimal performance.
