A thermoplastic material manufactured in a pre-formed shape in various sizes that can be adapted to fit more closely to an individual's teeth and gums by heating and molding such as boiling then placing in the mouth.
Some of the newer technologies offer an alternative, stronger thermo-polymer that allows for lower molding temperatures, below 140F to prevent burning by scalding hot water.
This is the most popular mouthguard used by amateur and semi-professional sportsmen, providing adequate protection but relatively low comfort in comparison to the custom-made guard.
People prone to nocturnal bruxism, or nighttime clenching, as well as morsicatio buccarum may routinely wear occlusal splints at night.
Originally, boxers fashioned rudimentary mouthguards out of cotton, tape, sponge, or small pieces of wood.
[17] Since these devices proved impractical, Woolf Krause, a British dentist, began to fashion mouthpieces for boxers in 1892.
Krause placed strips of a natural rubber resin, gutta-percha, over the maxillary incisors of boxers before they entered the ring.
Phillip Krause’s invention was highlighted in a 1921 championship fight between Jack Britton and Ted "Kid" Lewis.
Lewis was a school friend of Krause and the first professional to utilize the new technology, then called a ‘gum shield.’ During the fight, Britton’s manager successfully argued that the mouthpiece was an illegal advantage.
Carlos claimed that he made his first mouthpiece in 1916 and later suggested his invention to the United States Olympian Dinnie O’Keefe in 1919.
Dr. Clearance Mayer, a dentist and boxing inspector for the New York State Athletic Commission, described how custom mouthguards could be manufactured from impressions using wax and rubber.
In the January 1948 issue of the Journal of the American Dental Association, the procedure for making and fitting the acrylic mouthguard was described in detail by Dr.
[23] The first athlete to wear the acrylic mouthguard was a member of the UCLA basketball team, Dick Perry, who modeled the device at a convention of the Southern California Dental Association.
The ADA recommends mouthguards be used in 29 sports: acrobatics, basketball, bicycling, boxing, equestrian, football, gymnastics, handball, ice hockey, inline skating, lacrosse, martial arts, racquetball, rugby football, shot putting, skateboarding, skiing, skydiving, soccer, softball, squash, surfing, volleyball, water polo, weightlifting and wrestling.
