A method and apparatus for preventing sleep apnea employs an external clamp that has a first pad that engages the upper lip beneath the nose and a second pad that engages the lower jaw on its underside, behind the mandibular symphysis. The pads are connected to each other by a flexible member, or brace. Preferably the second pad is rounded on that portion that contacts the lower jaw. The clamp is held in place by one or more straps, braces or springs that pass about the patient's head. The first pad is held such that it presses against the upper lip while the second pad closes the lower jaw and pulls it forwardly and upwardly using relatively small forces.

An orthodontic extraoral traction appliance includes at least one central body, one or more rest portions to be positioned on the patient's head, and one or more traction portions, which engage an intraoral brace. The appliance is provided with one or more sensors for detecting and/or measuring the force exerted by the traction portions.

A mandibular positioning facial retrognathism orthodontic system and a design method thereof are disclosed. The orthodontic system includes a maxillary shell-like dental appliance having a shell-like body, a protrusion portion protruding toward an opposite jaw is disposed at a posterior area corresponding to the shell-like body, a traction portion is disposed at a labial side of the shell-like body, and a retaining portion configured for fastening with a retaining attachment is disposed at the posterior area corresponding to the shell-like body. The protrusion portion is engaged with the posterior area of a mandibular for occlusal reconstruction, so that mandibular incisors are aligned with maxillary incisors. The design method is a design method for the mandibular positioning facial retrognathism orthodontic system, which can provide a treatment-specific orthodontic system, thereby achieving treatment of mandibular positioning facial retrognathism.

Disclosed is a split wireless detection mask, including a mask and a base which can be connected to each other. The mask is wearable on a human body and configured for acquiring information of the human body. When the mask is connected to the base, the base charges the mask, the mask transmits the acquired information to the base, and then the base transmits the information to a cloud server. The mask includes a control unit, a detection unit, and a detection information transmitting unit. The detection unit detects information of the mask, and if the human body wears the mask, the detection unit stores the information in the control unit. The base includes a wireless transmission unit, a detection information receiving unit, and a power source unit. The detection information receiving unit receives data sent by the detection information transmitting unit.

A detachable orthodontic bracket and wire system includes bracket bases, brackets, and an arch wire for guiding alignment of teeth. The bracket bases are positioned on a lingual surface and/or a facial surface of the teeth. Each bracket base includes a first surface, a second surface, and at least one first interlocking element. The first surface is rigidly attached to the lingual surface and/or the facial surface of the teeth. The second surface opposes the lingual surface and/or the facial surface of the teeth. The first interlocking element is attached to and positioned in a direction substantially perpendicular to or parallel to the second surface of each bracket base. The brackets include at least second interlocking element that interlocks with the first interlocking element. The arch wire is inserted through a slot channel of each bracket. The bracket and the arch wire are infused and rigidly anchored within enclosing layers.

An extraoral orthopedic device for direct protraction of the maxilla and indirect protraction of the mandible of a patient, comprising a circular cranial support configured for placement around the periphery of the neurocranium of a patient encircling the forehead, two perpendicular girders adjustably coupled to the circular cranial support and extending in a downward direction on either side of the face of the patient, each of the two perpendicular girders having a plurality of openings extending diametrically therethrough and disposed distally relative to the circular cranial support; an intraoral mechanism disposed in the mouth of the patient; and a horizontal girder coupled through elastic tractions with the intraoral mechanism and adjustably supported within a respective slot of the plurality of openings in each of the two perpendicular girders.
