1、Designation: F697 16 An American National StandardStandard Practice forCare and Use of Athletic Mouth Protectors1This standard is issued under the fixed designation F697; the number immediately following the designation indicates the year of originaladoption or, in the case of revision, the year of
2、last revision. A number in parentheses indicates the year of last reapproval. A superscriptepsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers the care and use of intraoral mouthprotectors as protective equipment for sports. Mouth protector

It is therespons

Terminology2.1 Definitions of Terms Specific to This Standard:2.1.1 mouth protectora resilient device or applianceplaced inside the mo

Significance and Use4.1 Intra-oral mouth protectors have been found usable andeffective in all
7、physical sports activities where mouth hazardexists.4.2 Considerable evidence indicates that the use of mouthprotectors reduces forces on dentition and can potentiallymitigate orofacial injuries.5. Design Considerations5.1 For maximum protection, cushioning, and retention(that is, to reduce the chan
8、ce of dislodgement), the protectorshould cover all the remaining teeth of one arch, customarilythe upper, less the third molar (except with a prognathic lowerjaw). The borders of the mouth protector should cover as muchof the alveolus and extend to the depth of the vestibuleintraorally, without inte
9、rfering with the movement of theintra-oral tissues.5.2 The use of both a separate maxillary (upper) andmandibular (lower) mouth protector is seldom recommendeddue to no demonstrated benefit, reduced comfort with lack ofcompliance from individuals. The use of a combined (dualarch) maxillary and mandi
10、bular mouthguard is an acceptabledesign.5.3 Consideration needs to be given to how the mouthprotector occludes with the opposing teeth. The mouth protec-tor needs to have contact with as many teeth in the opposingarch and contact evenly on as many teeth as possible.5.4 Mouth protectors that attach t
11、o headgear via a strapshould be adjusted to fit as described above (for non-strapattached).6. Special Limitations6.1 The fitting of mouth protectors is best accomplishedunder the supervision of trained athletic, medical, or dentalstaff familiar with the specific mouth protector to be used.6.2 Player
12、s wearing orthodontic appliances or having mouthmalformations (abnormalities) should be provided with amouth protector only under the supervision of a dentist.6.3 Players wearing removable partial dentures should re-move them before being provided with a mouth protector.6.4 Players wearing complete
13、dentures should be fitted witha mouth protector (with or without the denture in place) asdecided and supervised by a dentist.6.5 If the changing dentition, due to the age of the player, isjudged to be a problem, the use of a thermally moldable mouth1This practice is under the jurisdiction of ASTM Co

The use of commer-cially available daily cleansing agents available for denturescan be used to effectively clean the mouth protector.7.2 Storage and ShippingAvoid excessive heat or cold.Custom-made protectors should be shipped or stored in such away that the
18、ir ability to fit and be retained on athletes dentitionis preserved. More specifically, they should be protected fromtemperatures and forces that could alter their shape and extentof coverage of dentition. Antimicrobial storage cases can beused to store mouth protectors between instances of use.7.3
19、Mouth-FormingFor forming the thermally moldablevariety, have the protector wet (do not insert in the mouth dry).7.4 UsePlayers should be instructed to use mouth protec-tors when engaged in any physical sport activity where thehazard of mouth injury exists, including sports where helmetswith face pro
