Disadvantages are that they available only in limited sizes, do not fitvery well, inhibit speech and breathing, and require the jaws to be closed to hold the mouth guard in place.oBecause the stock mouth guards do not fit well, the player may not wear the mouth guard due to discomfort and irritation. Orthodontists will often recommend these becausethey allow for protection of soft tissues while allowing tooth movement. oIn doing so, the ASD feels that they do not allow for adequate protectionof the teeth. oThe ASD has stated that the stock mouth guard is unacceptable as an orofacial protective device.Mouth-Formed Protectors There are two types of mouth-formed protectors: oshell-liner
othermoplastic The shell-liner typeis made of a preformed shell with a liner of plastic acrylic or silicone rubber. oThe lining material is placed in the player’s mouth and molds to the teeth and then is allowed to set. The preformed, thermoplastic typealso has a lining that is immersed in boiling water for 10-45 seconds, transferred to cold waterand then adapted to the teeth (also known as “boil and bite” guard). oThis mouth guard seems to be the most popular of the three typesand is used by more than 90% of the athletic population.Custom Made Mouth guards Superior of the three typesand the most expensive to the athlete. Dental professionals believe this to be well worth the cost to protect an athlete’s teeth from injury.This mouth guard is made ofthermoplastic polymer and fabricated over a model of the athlete’s dentition.The mouth guard is made by the dentistand fits exactly to the athlete’s mouth. Advantages includefit, ease of speech, comfort and retention.oBy wearing a protective mouth guard, the incidence of a concussion by a blow to the jaw is significantly reduced because the condyle is separated from the base of the skull by placing themandible in a forward position.There are two types of custom mouth guards:oCustom Vacuum Formed Mouth guardis most common.This is the most widely made mouth guardby the dental profession.It offers good protection with the least interference to speaking and breathing. They are fabricated from a single sheet of EVA polyvinylacetate polyethylene copolymer. TThe EVA sheet is heated, placed over the stone model, and suctioned by vacuum to fit to the shape of the mouth and teeth. Been found to decrease in thickness occlusal by 25%,While the buccallingual surfaces 50% +. They have been found to retain their shape for only a few weeks after wearing. They will not provide protection for long periods of time and should be closely monitored. oPressure-Laminated Mouth guardsConsidered the best mouth guards available.
Made of multiple sheets of laminating EVA materialsthat are heated, placed over a stone model, and pressed onto the model or previous laminate with a maximum pressure of 6 atmospheres.
