A removable orthodontic assembly to be used in a user's mouth, including: a frame member configured to be removably positioned proximate a lingual portion of the user's teeth; a first connector member, wherein the first connector member comprises a first end extending proximate to a labial portion of the user's teeth and a second end engaging the frame member; and a labial bow configured to be removably positioned proximate to the labial portion of the user's teeth having a first end and a second end, wherein the labial bow is configured to removably engage the first connector member.

Dental braces according to one embodiment of the present invention comprise: wires for straightening teeth; a coating agent coated on the outer surfaces of the wires; and fixing parts for fixing the wires, coated with the coating agent, on the surfaces of the teeth and fixing the wires such that the wires can move along the longitudinal direction of the wire, wherein the coating agent coated on the wires is removed from the wires after the coating agent is covered with the fixing part, such that a clearance gap can be formed between the fixing part and the wire, thereby enabling accurate and smooth teeth-straightening.

The dental appliance-holding bracket assembly includes a plurality of housings attached to a corresponding tooth band, each of the tooth bands being cemented to the crown of an adjoining tooth. Each housing defines a socket of a ball-and-socket joint. The assembly further includes a plurality of bracket arms, each bracket arm having a shank including a proximal end and an opposing distal end. The proximal end of the shank has a ball pivotally captured within the housing socket to form a ball-and-socket joint, while the opposing distal end of the shank includes a ring adapted for supporting a dental appliance.

Disclosed is an orthodontic composite, comprising: an orthodontic member which has a tube shape, a hollow polygonal prism shape, a hollow truncated polygonal pyramid shape, a hollow truncated cone shape, or a funnel shape; and an orthodontic wire that is inserted into the hollow portion of the orthodontic member, wherein the orthodontic member includes a water-soluble or biodegradable material. Thereby, the orthodontic composite of the present invention making it simple to perform orthodontic treatment by attaching the orthodontic composite.

The present disclosure relates to an orthodontic system and a method of using the same to perform orthodontics. In one example, an orthodontic system is presented. The orthodontic system includes a tube having at least one sidewall and two opening ends, and a luting agent. The luting agent is disposed on at least a portion of one or more of the at least one sidewall of the tube and a portion of a surface of a tooth onto which the tube is directly attached or adhered. The two opening ends of the tube remain substantially open so that a wire can move along the tube.

The present disclosure supplies molar appliances having a tooth bonding base that includes compound curvature in the mesial-distal direction, providing for a closer fit relative to the buccal surface contour. The appliances can also feature a funneled entry to an archwire passage that includes a plurality of surfaces with a convex curvature, providing a curved taper to a distal section of the passage. The continuously curved surfaces guide the end of an archwire into the passage, while minimizes or avoiding abrupt transition areas that can impede insertion. The appliances of the present disclosure can include a buccal surface on the appliance body that is substantially parallel to the torque plane of the appliance.

Disclosed is an orthodontic member, having a tube shape, a hollow polygonal prism shape, a hollow truncated polygonal pyramid shape, a hollow truncated cone shape, or a funnel shape, and including a water-soluble or biodegradable material, wherein the orthodontic member into which a wire is inserted is attached to the teeth, thereby making it simple to perform orthodontic treatment.

Packaged orthodontic assemblies include a chamber, an orthodontic appliance, and a support structure engaged with the appliance to secure the appliance in the chamber. The support structure can include a post complemental to a partially enclosed passage, typically an arch wire slot, in the appliance body. The support may orient the wall sections of the enclosed passage at an acute angle relative to a chamber side wall.

A method and apparatus with auto-inactivation for the lateral expansion or constriction of posterior teeth, anterior advancement or retraction of the anterior teeth, and distal expansion of the molars, bicuspids and canines is described. This system is for correction of the upper dental arch and jaw bone, nasal cavity constriction, or lower dental arch constriction, which helps to resolve the dental malposition, dental crowding, proper room for tongue position, and expansion of nasal cavity for improvement of airway. The appliance includes loaded springs around the wires connected to molar band with connector tubes and female attachments that are extended to the front tube. The spring creates a distalization force on the first and/or second molars, anterior extending force on front teeth including canines and incisors, and lateral expansion for the posterior teeth including, canines, bicuspids and molars.

Aerogel, calcined articles, and crystalline articles comprising ZrO.sub.2. Exemplary uses of the crystalline metal oxide articles include dental articles (e.g., restoratives, replacements, inlays, onlays, veneers, full and partial crowns, bridges, implants, implant abutments, copings, anterior fillings, posterior fillings, and cavity liner, and bridge frameworks) and orthodontic appliances (e.g., brackets, buccal tubes, cleats, and buttons).
