The Custom Comfort Nightguard is a modification to DenTek Oral Care Inc.'s DenTek Nightguard (K063483). ## Intended Use DenTek's Custom Comfort Nightguard is indicated for use for protection against bruxism or nighttime teeth grinding. It is intended to reduce damage to the teeth and to prevent the noise associated with bruxing or grinding. ## Technological Characteristics The Custom Comfort Nightguard is a fully occlusive nightguard, consisting of a soft, formable material, and non-formable base, which cushions the teeth. When heated and then briefly cooled, the formable material is molded to fit the user's maxillary dentition for maximum retention. The hard base prevents bite-through by users with moderate to severe nocturnal bruxing and cushions the teeth on all occlusal surfaces. The Custom Comfort is designed with an anterior area formed from the soft, formable material that allows for expansion and contraction of the device to fit most mouth sizes. ## Substantial Equivalence DenTek's Custom Comfort has the same intended use and similar indications, principles of operation, and technological characteristics as the Den'tek Nightguard. The minor modification made in the device does not raise any new questions of safety or effectiveness. Thus, the Custom Comfort is substantially equivalent to its predicate device. {2}------------------------------------------------ #### DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/2/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
