The present invention relates to a scan body (7), which comprises a cylindrical or polyhedral shaped body and around its body protruding macro geometrical shapes, said shapes being distinct among them when used at least two. Additionally, the present invention relates to a helical chain (7) comprising a plurality of links (8), said links (8) having a rotation off set of 20 degrees clockwise or anti-clockwise with respect to the preceding link (8). At least two scan bodies (2) and one helical chain (7) form a system for intraoral scanning, wherein the helical chain (7) is positioned between at least two scan bodies (2), wherein the links (8) slide to at least two grooves of the scan bodies (2), each.

An orthodontic bracket is provided, including a backend surface, a frontend surface, a first side surface, a second side surface, and a passageway. The backend surface is adapted for attachment and is opposite the frontend surface. The first and second side surfaces are connected between the backend surface and the frontend surface. The passageway extends from the first side surface to the second side surface. The cross-section of the passageway includes an access opening, an archwire slot, a path portion, and at least one rotation portion. The access opening is configured to allow the archwire to enter the passageway. The archwire slot is configured to receive the archwire. The path portion connects the access opening and the archwire slot. The rotation portion is provided in the path portion to allow the archwire to change its orientation.

An orthodontic appliance, includes a crimpable tubular shaped portion having at least three walls selected from the group consisting of a lingual wall, a buccal or labial wall, an occlusal wall and a gingival wall, the at least three walls defining and opening configured to receive an archwire therethrough in a mesial-distal direction. The appliance includes at least one wing joined to the tubular shaped portion, the at least one wing extending longitudinally in the mesial-distal direction. A slot is provided in the at least one wing open to an end of the wing in the mesial or distal direction and having a depth in the mesial distal direction and a height in a gingival-occlusal direction configured to receive a ligature wire or elastic.

Various embodiments of an orthodontic appliance are provided. In one embodiment, an orthodontic appliance is provided, the appliance comprising: a body; at least one ring-shaped member connected to the body via at least one connecting portion; wherein the body and the at least one ring-shaped member are oriented adjacent to one another; and wherein the body and the at least one ring-shaped member are not coplanar when in an unloaded state.

An orthodontic bracket is used for correcting the dentition of a patient. The orthodontic bracket includes a wire holder having a wire hole (through-hole) through which an arch wire for orthodontic treatment is inserted, and a bracket base that detachably supports the wire holder and is affixed to a tooth surface of the patient.

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.
