 There are some modifications of this technique whereby sports mouth guards are made by having the athlete take his own impression and then fabricating the mouth guard in a laboratory. This reduces the cost somewhat. A greatly simplified one-step, rapid, low cost process would be highly desirable.
Bleaching agents are commonly used to whiten teeth. To afford an even, cosmetically attractive whitening process over all the targeted teeth, it is desirable to find some method in which the bleaching agent can be applied uniformly. During the bleaching process, it would be advantageous to isolate the teeth undergoing whitening within the oral cavity since the process may require several minutes to several hours for completion. In such instances, it is further desirable to limit the potential ingestion of bleaching agents by the patient as well as the exposure of dental tissues to these agents. In some cases, the bleaching agents are applied to the teeth and, thereafter, the bleaching action is aided by the exposure to UV light.
Periodontal disease, popularly called gingivitis, is present to varying degrees in approximately 85% of the population. In severe cases this bacterial disease results in serious infections of the gums with accompanying soreness and bleeding and may eventually lead to erosion of the teeth below the gum line and their subsequent loss. Treatments for periodontal disease include antibacterial agents that kill bacteria responsible for periodontal disease on contact and oxidizing agents that remove the protective bacterial biofilm formed on teeth and gums that promotes bacterial reinfection. The devices of this invention can be employed in two ways to mitigate the effects of periodontal disease. Custom fit trays can be readily, quickly and inexpensively constructed using the technology described herein. These trays can be filled with antibacterial and/or oxidizing agents.
Certain common requirements are necessary to successfully address all of the above targeted dental appliances and other applications. First, the materials employed must possess no appreciable oral or dermal toxicity. They should be odorless and tasteless and should provide no permanent bonding to oral tissues or teeth. They should release easily and cleanly from those tissues and teeth to preserve fine details and fit of the dental appliance. The materials should be compatible with water and saliva as well as other agents commonly found in oral fluids and should undergo no appreciable degradation in the presence of those agents. Silicones, i.e. poly(dimethylsiloxanes), possess all of these properties and are, therefore, the favored materials of choice for such applications.
