Abstract: Protrusions or holes with jagged edges formed on the lingual side of invisible aligner trays are provided. The protrusions or holes irritate the tongue causing it to retract away from the incisors thus eliminating intruding force otherwise exerted by the tongue. A clear corrugated material is provided which is suited for making the aligner trays having the protrusions which otherwise would be difficult with standard thick material used. The lingual side protrusions are added by computer to the impressions taken from a patient's teeth such that the protrusions are formed on the dental model used to make the aligner trays.

Abstract: A habit corrector appliance including a front portion, a first ramp and a second ramp extending from the front portion.

Abstract: An automated tissue retention system generally comprises an oral appliance retractably coupled to a covering which is secured to an anterior portion of the tongue. Once placed within a subject's mouth, the appliance may be maintained in a closed configuration while the subject's mouth remains closed. However, as the subject sleeps and the tongue becomes hypotonic, the subject's mouth typically opens during a sleep disordered event. The appliance may be actuated by the separation between the mandible and maxilla to have greater tension and thus retract or pull anteriorly the covering adhered to the tongue. As the covering pulls the tongue anteriorly or maintains a position of the tongue, the base of the tongue may be inhibited or prevented from collapsing posteriorly against the phryngeal tissue walls and thereby allow the subject to breathe normally.
