A mandibular advancement device with enhanced stability, including an upper tray assembly formed by an upper moldable component and an upper bracket, and a lower tray assembly formed by a lower moldable component and a lower bracket. The upper bracket and the lower bracket each extend a front wall from their front side edges near the labial side, while at least the lower bracket extends a rear wall along the median sagittal plane from the rear side edge near the lingual side. The stability is achieved by inclining the front wall of at least the upper bracket towards the lingual side. The rear wall of the lower bracket works in conjunction with the front wall to clamp the lower dental arch. Additionally, the stability feature includes a molar clamping section, further enhancing the overall stability of the mandibular advancement device.

A mandibular advancement device includes an upper tray assembly and a lower tray assembly. The upper tray assembly includes an upper moldable component and an upper frame, and the lower tray assembly includes a lower moldable component and a lower frame. The device has a terminal point near the lingual side, and near the terminal point, at least one protrusion is provided on the upper frame and the lower frame. The at least one protrusion is configured to allow the patient's mouth to open and close and to maintain the relative front-to-back position of the upper frame and the lower frame, thereby allowing the device to keep the patient's airway open by advancing the mandible.

An oral device that includes an upper tray assembly and a lower tray assembly. The upper tray assembly includes an upper moldable component and an upper bracket, while the lower tray assembly includes a lower moldable component and a lower bracket. Additionally, the oral device has an end point positioned away from the lip side when the patient uses it. An advantage of this disclosure is that the upper bracket has at least one downward-facing lower protrusion near the end point, while the lower bracket includes at least one upward-facing upper protrusion near the end point. The disclosure meticulously defines various parameters and positions for the upper and lower protrusions, ensuring the oral device is better suited to meet the patient's needs.
