Abstract
A mandibular advancement device is described, and may include an upper portion for fitting to maxillary teeth and a lower portion for fitting to mandibular teeth. The system may include one or more connecting bars, which may be provided in varying lengths, that allow the upper portion and lower portion to be pivotably connected such that horizontal and vertical articulation are possible. A kit is also described, which may allow a user to mold the device to their teeth and select from a plurality of connecting bars having different lengths.
Claims15
A mandibular advancement device, comprising:
- an upper moldable element moldable to a user's maxillary teeth;
- an upper shell with a receptacle that receives the upper moldable element, the upper shell comprising a first upper bracket on a posterior location of a first outer perimeter side of the upper shell and a second upper bracket on a posterior location of a second outer perimeter side of the upper shell, each of the first upper bracket and the second upper bracket comprising an elongated slot and a pocket;
- a lower moldable element moldable to a user's mandibular teeth;
- a lower shell with a receptacle that receives the lower moldable element, the lower shell comprising a first lower bracket on an anterior location of a first outer perimeter side of the lower shell and a second lower bracket on an anterior location of a second outer perimeter side of the lower shell, each of the first lower bracket and the second lower bracket comprising an elongated slot and a pocket;
- and
- a first connecting bar and a second connecting bar, each of the first connecting bar and the second connecting bar comprising a first end and a second end, the first end and the second end of each of the first connecting bar and the second connecting bar including:
- a projection receivable within the elongated slot, rotatable within the elongated slot, and slidable along a length of the elongated slot of the first upper bracket, the second upper bracket, the first lower bracket, and/or the second lower bracket;
- and
- a knob receivable within the pocket of the first upper bracket, the second upper bracket, the first lower bracket, and/or the second lower bracket.
A method performed by a user of fitting a mandibular advancement device to the user's mouth, comprising:
- molding an upper moldable element to a user's maxillary teeth;
- molding a lower moldable element to a user's mandibular teeth;
- selecting a pair of connecting bars from a plurality of pairs of pre-made connecting bars of various lengths;
- inserting a first knob at a first end of each connecting bar into a slot and a pocket of a bracket of an upper shell carrying the upper moldable element, the pocket being defined by the bracket and the upper shell;
- and
- inserting a second knob at a second end of each connecting bar into a slot and a pocket of a bracket of a lower shell carrying the lower moldable element, the pocket being defined by the bracket and the lower shell, each connecting bar and slot capable of accommodating slight anterior-posterior movement of the mandible.
