Abstract
An intra-oral device includes an upper splint, a lower splint and a pair of lateral connecting rods. Each connecting rod has a first rod end that connects to the lower splint and a second rod end that connects to the upper splint. The connecting rods are configured to maintain the mandible in an advanced position relative to the maxilla. The upper splint includes at least one upper gutter portion that retains the upper splint on the maxilla. The lower splint includes at least one lower gutter portion that retains the lower splint on the mandible. The thickness of the at least one upper gutter portion and/or the at least one lower gutter portion may vary across the profile of the teeth.
Claims27
An intra-oral device designed to fit in a patient's mouth, comprising:
- an upper splint, configured to engage with at least a portion of one or more teeth on the patient's maxilla, wherein the upper splint includes at least one upper gutter portion configured to engage said at least the portion of one or more teeth on the maxilla to retain the upper splint on the patient's maxilla;
- and
- a lower splint configured to engage with at least a portion of one or more teeth on the patient's mandible, wherein the lower splint includes at least one lower gutter portion configured to engage said at least the portion of one or more teeth on the mandible to retain the lower splint on the patient's mandible,
- wherein a thickness of the at least one upper gutter portion and/or the at least one lower gutter portion varies, and a retention portion of the at least one upper gutter portion and/or a retention portion of the at least one lower gutter portion has a varied thickness profile,
- wherein the upper splint comprises an upper band portion between two upper gutter portions of said at least one upper gutter portion and the upper band portion is configured to extend across a front portion of upper central incisor teeth,
- wherein the lower splint comprises a lower band portion between two lower gutter portions of said at least one lower gutter portion and the lower band portion is configured to extend across a front portion of lower central incisor teeth while the two lower gutter portions are configured to engage said at least the portion of one or more teeth on the mandible, and
- wherein the lower band portion is configured to be positioned directly in front of the front portion of the lower central incisor teeth when the intra-oral device is worn by the patient,
- wherein a surface of the lower band portion is configured to be inclined relative to a first plane that is perpendicular to a lower sliding plane surface when the intra-oral device is worn by the patient, the lower sliding plane surface being configured to be parallel to the patient's occlusal plane,
- wherein the surface of the lower band portion is configured to angle outwardly from a bottom to a top of the lower band portion to form an acute angle with the lower sliding plane surface when the intra-oral device is worn by the patient, and
- wherein the surface of the lower band portion forming the acute angle is configured to be positioned in front of the lower central incisor teeth when the intra-oral device is worn by the patient.
