A dual layer mouthguard with a U-shape polycarbonate/EVA skeletal base includes channels and ramps to ensure a uniform thickness on the occlusal, buccal and lingual surfaces of the teeth for proper alignment of the jaw and positioning for protection during the placement of the mouthguard. The liner is softer than the base when introduced to heat and remains softer as it is cooled. The base may also include metal/magnetic insertion to serve as a tethering device for temporary storage.

Medical devices have a polymeric nanocomposite treatment portion configured for contact with a treatment site within an oral cavity of a user and configured for operative communication with a controller. The polymeric nanocomposite treatment portion has a mucosal contact layer comprising a biocompatible polymer and defining a plurality of pores therethrough; a continuous support layer comprising a biocompatible polymer; an electronic network layer between the mucosal contact layer and the continuous network layer; and a means for applying pressure to the treatment site. The electronic network layer has carbon nanostructures and has a quantum micro-chiplet QMC or an octagonal quantum micro-chiplet integrated with a photonic integrated circuit. The electronic network layer is in operative communication with the controller and the power source. A pressure sensor that measures growth pressure is present and is positioned at the treatment site.

A magnetic removable orthodontic assembly for moving selected teeth of a patient includes metal engagement plates that are fixed in place in alignment with the selected teeth. A series of wire guides that contain magnets are contacted to the selected teeth by way of engagement with the teeth engagement plates. The engagement plates have first engagement members that engage complementary-shaped second engagement members on the wire guides in a removable fashion. The wire guides are mounted in a pattern to an archwire. The wire guides may be disengaged from their corresponding engagement plates so that the wearer of the appliance can remove and re-engage the device when necessary without having an orthodontist do it.

In one aspect, the present invention is directed to an orthodontic bracket, comprising: a vertical bore; a bendable drop-in hook threaded into the vertical bore; and an annular magnetic object, in which the drop-in hook is threaded into. In another aspect, the present invention is directed to an orthodontic braces arrangement, comprising: at least two distant brackets, each installed on a different jaw of a user; and each of the distant brackets having at least one annular magnetic object secured thereto by a bendable drop-in hook; wherein a distance between magnetic objects of one bracket and another bracket is less than 2 mm; thereby providing intermaxillary attraction or propulsion force, depending on a polarity orientation of the magnetic objects.

An aesthetic, partially removable orthodontic appliance is described, including a polymeric body that conforms to the lingual soft tissue and at least one wire member extending from the polymeric body. Each wire member releasably engages with a respective anchor that is, in turn, connected to the lingual surface of a respective tooth when the polymeric body is moved in a generally gingival direction into abutting relationship with the lingual soft tissue. Other features of the appliance include self-guiding magnetic couplings and couplings based on interlocking mechanical structures that provide releasable engagement between the removable section and the anchors, as well as related methods for making and using the same.

An orthodontic system and method for aligning at least one tooth of an upper jaw or a lower jaw of a patient. In the system and method at least one orthodontic appliance can be provided which may include at least one force exerting member for applying a force to move the at least one tooth, a tooth movement sensor for obtaining tooth movement data, and a tooth movement monitor for calculating at least one of the distance the at least one tooth has moved and a current position of the at least one tooth from the tooth movement data. An electronic control console may be operatively connected to the force exerting member and in data communication with the tooth movement monitor, for controlling the operation of the force exerting member using the at least one of the distance the at least one tooth has moved and the current position of the at least one tooth.

A sequential orthodontic appliance includes a body and one or more first magnets disposed on the body and arranged to provide either repulsive or attractive force between one or more second magnets disposed on a surface of a tooth in need of repositioning. One or more temporary anchorage devices are used to secure the appliance to a person with the body disposed approximate the tooth.

In one aspect, the present invention is directed to an orthodontic bracket (12), comprising: a vertical bore (32); a bendable drop-in hook (34) threaded into the vertical bore (32); and an annular magnetic object (30), in which the drop-in hook (34) is threaded into. In another aspect, the present invention is directed to an orthodontic braces arrangement, comprising: at least two distant brackets (12), each installed on a different jaw of a user; and each of the distant brackets (12) having at least one annular magnetic object (30) secured thereto by a bendable drop-in hook; wherein a distance between magnetic objects of one bracket and another bracket is less than 2 mm; thereby providing intermaxillary attraction or propulsion force, depending on a polarity orientation of the magnetic objects.

A self-ligating orthodontic bracket for ligating an archwire includes a bracket body defining an archwire slot configured to receive the archwire, a movable member movable relative to the archwire slot, and an actuator coupled to at least one of the bracket body and the movable member. The actuator includes a ferromagnetic shape memory alloy and is configured to move the movable member when exposed to a magnetic field. A method of orthodontic treatment using a self-ligating orthodontic bracket having an archwire slot configured to receive an archwire therein and including a ferromagnetic shape memory includes exposing at least a portion of the orthodontic bracket to a magnetic field such that the ferromagnetic shape memory alloy at least partially transforms to a martensitic phase from an austenitic phase, and at least one of inserting an archwire into the archwire slot and removing an archwire from the archwire slot.

An orthodontic appliance can easily achieve and ensure movement of correction target tooth row in a desired direction and achieve highly predictable treatment is provided while anchorage is satisfactorily ensured. A correction device includes a grip member formed to fit to an inner shape of an oral cavity of a patient so as to grip and cover a tooth row, gum parts, and alveolar bone parts of the patient. The correction device includes a first piece 20 covering an area extending from a crown part to a periphery of a cervical part of a correction target tooth and a second piece included in the grip member. The correction device further includes a force applying member 30 provided to connect the first piece 20 to the second piece 10 and configured to move the correction target tooth in a desired direction.
