A bracket system for orthodontic appliances including a bracket combinatorial library having a plurality of brackets each interchangeably fixedly mountable to each of a plurality of teeth within a dentition group in a dental arch, whereby the plurality of brackets can be configured to provide incremental variation in tipping force moments, in-out force moments, and torqueing force moments over the entire useful range of orthodontic mechanics, allowing an orthodontic practitioner to prescribe a combination of tipping force moments, in-out force moments, and torqueing force moments unique for each tooth in relation to the plurality of teeth of a patient.

An orthodontic bracket assembly includes a mounting plate configured to be coupled to a tooth and a bracket member. The bracket member has a first portion generally extending in a first direction, a second portion generally extending in a second direction opposite to the first direction, and a slot defined intermediate the first and second portions. The slot is configured to receive a wire. Additionally, each of the first and second portions includes a curved surface defining an entrance of the slot.

An orthodontic correction device set up within an oral cavity of a patient. It includes a bone screw member that has a plate, the plate includes at least a positioning portion, and a surface of the plate includes at least a fixing member; at least a bone screw is in connection with at least a positioning portion of the bone screw member, and that is fixed by implanting into the oral cavity; at least a base body is assembled on a surface of the teeth and including a connecting portion; and at least an elastic member, a fixing end of the elastic member is assembled and fixed on the fixing member of the bone screw member, a functioning end of the elastic member is in mutual connection with the connecting portion of the base body, and an orthodontic correction force is formed between the fixing end and the functioning end.

An orthodontic bracket includes a bracket body and a ligating member. The ligating member retains an archwire in an archwire slot and includes archwire control structure including projecting portions spaced apart in a mesial-distal direction with a recessed area therebetween. The recessed area and the projecting portions overlie the archwire slot. The recessed area may include a flat or a curved surface in a mesial-distal direction. The recessed area and projecting portions may define a radius of curvature that is less than the radius of curvature of the archwire seated in the slot. The archwire contacts one or both the projecting portions resulting in a larger moment arm and better rotational control of the bracket with the force applied by the archwire.

Embodiments of the present invention provide devices (tags with sensors), systems, and methods to determine states (such as, but not limited to, complex impedance) of materials-of-interest, such as tissue-of-interest, implants, and construction members, to name a few, in a non-invasive and contactless way; and using comparatively safe and/or low energy electromagnetic radiation, such as radio waves. Negligible-sized wireless-tags with sensors are implanted in such materials-of-interest. Using wireless communication and imaging technology, the states of the materials-of-interest may be monitored; which may allow non-invasive and contactless detection of problems such as cracking, bending, excessive pressure, improper temperature, and/or the like. Additionally, initially unknown locations of the implanted negligible-sized wireless-tags with sensors may be readily determined upon a given scanning (reading) session; and thus mapped to provide an effective image of the material-of-interest.

An orthodontic ligature for securing an orthodontic archwire to an orthodontic bracket. The orthodontic ligature is formed of a resilient band which forms a flap. The flap forms a grip portion. The resilient band defines a non-circular hole having a major dimension along the direction in which the grip portion extends. The invention provides an easy to use orthodontic ligature which further is maximized in durability.

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.

A self-ligating bracket system comprising a body, an archwire slot receivable for an archwire, and a locking mechanism, the locking mechanism configured to allow a ligating sliding member to move between an open position, such that an archwire may be inserted into and/or removed from the archwire slot, and a closed position, such that an archwire is retained within the archwire slot.
