Definitions

  • the present invention relates to a moulded mouthguard .
  • Mouthguards have been used by sportsmen to prevent damage to their teeth. In essence, the mouthguard aims to absorb energy associated with an impact and/or to transfer forces applied to the front teeth during an impact towards the much stronger back teeth . To this end, the back teeth have 5 times the thickness and 2-3 times the number of roots.
  • This type of store bought mouthguard is made from a thermoplastic material, which can be reformed by placing it in boiling water for 10-45 seconds. The heated mouthguard is then placed in the mouth and the athlete is instructed to close the lips and using a sucking action to help mould it to the teeth and gingival tissues.
  • Custom Made Mouthguard The dentist takes an impression of the athlete's maxillary dental arch and then makes a cast. A vacuum-heating unit is used by the dentist and a soft vinyl material is suctioned over the cast to create an exact fit.
  • This type of mouthguard is often made of polyvinyl acetate-poly-ethlene product. Since this type of mouthguard fits the athlete's mouth precisely, thus breathing and talking are made easy.
  • the mouthguard at least partially wraps around the sides of each tooth. As such, forces from a point load on the front teeth are better transferred to the neighbouring teeth . This improved transfer of the load results in optimal protection for the teeth.
  • Moulded mouthguards clearly have superior performance over store bought mouthguards. However, they still have performance issues, including :
  • Mouthguards are typically 3 to 5 mm thick. When fitted, the mouthguard effectively applies a 3 to 5 mm layer of impervious ethyl vinyl acetate (EVA) material over a row of teeth and part of the gums.
  • EVA impervious ethyl vinyl acetate
  • the volume of an average mouth is 37 millilitres for females and 85 mill i litres for men .
  • mouthguard occupies a considerable amount of real estate in the mouth, which reduces the capacity of the mouth to hold oxygen. Consequently, the amount of oxygen that the mouth can feed into the lungs may be reduced .
  • the teeth act as a natural barrier blocking airflow into and out of the mouth.
  • the mouthguard When fitted, the mouthguard increases the size of this barrier, further decreasing the size of the opening at the front of the mouth through which air travels into and out of the lungs. Consequently, the amount of oxygen fed into the lungs from the mouth may be reduced .
  • the mouthguard acts as a barrier to saliva flowing through the top teeth, for example, reducing the person's comfort level .
  • the solid mass of the mouth guard inhibits the athlete's ability to talk when it is in place. In team sports, the mouth guard can inhibit communication between players and complicate and/or frustrate on field communications.
  • a moulded mouthguard for protecting a row of teeth in a person's mouth including:
  • front section and back sections are at least partially perforated with slots extending therethrough so that air and/or saliva can flow through the row of teeth .
  • the front and back sections are both perforated with slots in positions corresponding with bordering sections of neighbouring teeth in said row of teeth so that air and/or saliva can flow through the row of teeth .
  • the front and back sections are substantially perforated with slots so that air and/or saliva can flow through the row of teeth.
  • the introduction of the perforation slots in the mouthguard advantageously addresses one or more of these problems.
  • the mouthguard 10 has the following advantages:
  • the mouthguard uses the natural arch of the row of teeth 12 to spread point loads to the stronger teeth .
  • the slots are preferably defined by triangular segments that are arranged to form a lattice structure.
  • the segments are preferably generally triangular.
  • the mouthguard comprises the lattice formed by the triangular segments.
  • the lattice is a Stochastic lattice.
  • the step of perforating includes the step of cutting perforations into the mouth guard.
  • the step of cutting is effected using a laser cutter or a a high pressure water cutter.
