Custom mouthguard
View Patent ↗A custom mouthguard has a resilient U-shaped body with an anterior wall and a posterior wall. A post dam on the posterior wall forms a seal with palatal tissue to increase retention of the mouthguard in a wearer's mouth. The increased retention allows a wearer to speak and open mouth breath while wearing the mouthguarrd. The mouth guard also has an indexed region that serves to mutually stabilize maxillary teeth, mandibular teeth, mandible and TMJ components. Mouthguard methods and processes are also disclosed.
1. A mouthguard device for an individual wearer for mutually stabilizing maxillary teeth fitting into the mouthguard, mandibular teeth interacting with the mouthguard, a mandible and associated condylar heads seated in medially braced positions in glenoid fossae while simultaneously maintaining open-mouth breathing and speaking and muscle comfort in associated tissues, the mouthguard device comprising:
an upwardly directable U-shaped trough, the trough having a bottom, a posterior wall arising from the bottom, and an anterior wall arising from the bottom, each of the walls having an upper edge, an inwardly directed surface and an outwardly directed surface, the U-shaped trough being custom molded from a maxillary cast of the individual wearer to closely conform to the maxillary teeth and adjoining gum tissue and adjoining palatal tissue of the individual wearer;
a post dam, comprising a generally continuous ridge, upon the inwardly directed surface of the posterior wall adjacent the upper edge of the posterior wall for forming a seal with palatal tissue to increase retention of the mouthguard device in a mouth and wherein the post dam comprises a raised roughly hemispherical cross-sectional structure with an anterior bevel of roughly 45 degrees that extends laterally from a lingual free margin of an interproximal gingiva at a mesial of a first molar on one side to that of an opposite side of the mouth and resiliently contacts the wearer's gum tissue; and,
wherein the outwardly directed surface on the posterior wall adjacent the bottom of the U-shaped trough interacts with crowns of the mandibular teeth to limit motion of the mandibular teeth and prevent contact of the maxillary teeth with the mandibular teeth when the mouthguard is clenched between the mandibular and maxillary teeth.
