摘要： An orthodontic bracket has been designed which can be made of ceramic material. The bracket can be used for correcting Class II and Class III malocclusions without the use of a Kobiashi tie, ball hook, or power hook, which had previously been used to make such corrections. This invention, on the other hand, employs an integral hook design, which makes use of the same mechanics, but without requiring any brazing or welding of the hook to the body of the bracket.

摘要： Orthodontic brackets made of a light-transmissive material such as plastic or ceramic have a removable, water-based colorant to facilitate identification of the bracket and alignment of the bracket on the patient's tooth. The colorant is received in a ligature channel of the bracket and is visible through adjacent tiewings of the bracket. The colorant is protected by the overlying tiewings from inadvertent damage or removal as might otherwise occur during initial handling and placement of the bracket.

摘要： An orthodontic appliance such as a bracket or buccal tube has a latch for retaining an archwire in an archwire slot. The appliance also includes built-torque in order to reduce the need for the practitioner to manually bend the archwire by twisting the archwire about its longitudinal axis during the course of treatment. The latch comprises at least one clip having certain features that significantly reduce strain during opening movements of the clip. As a result, the fatigue life of the clip is enhanced.

摘要： An orthodontic appliance includes a latch that comprises at least one clip with a region for receiving an archwire. The clip also includes a recess for receiving a post of the appliance and for coupling the clip to remaining components of the appliance. The clip includes at least one protrusion that extends between the post-receiving recess and the archwire-receiving region, and the protrusion serves to retain the clip in place on the post.

摘要： A ceramic orthodontic bracket has a centrally located clip for retaining an archwire in an archwire slot. The body of the bracket includes a mesial section, a distal section, and a bridge section, wherein the bridge section extends through, and retains, the clip. The bridge section also includes a recess adjacent to the bridge section that facilitates debonding of the bracket from a patient' s tooth. Preferably there are gaps on one or both sides of the clip to allow space for debonding of the bracket by applying a mesial-distal compressive force on the bracket and fracturing the bracket along the recess. This configuration allows the overall mesial-distal width of the bracket to be reduced, thereby facilitating the bonding of brackets to narrow and/or maloccluded teeth. Another embodiment includes a stop member that is connected to the base of the bracket and retains the clip on the bridge section.

摘要： An orthodontic appliance such as a bracket or buccal tube has a latch for retaining an archwire in an archwire slot. The latch releases the archwire from the archwire slot whenever the archwire exerts a force on the appliance that exceeds a certain minimum value. The latch comprises at least one clip having certain features that significantly reduce strain during opening movements of the clip, so that the likelihood of fracture of the clip during use is significantly reduced.

摘要： A cap is releasably connected to an orthodontic bracket and covers tips of occlusal bracket tiewings in order to prevent contact of the bracket with the enamel of opposing dentition. The cap includes a section that extends at least partially along a channel of the bracket extending in a generally occlusal-gingival direction in order to help retain the cap in its intended position and prevent the cap from rotating relative to the bracket. In preferred embodiments, the cap is made of a stain-resistant aesthetically pleasing material. Optionally, the cap serves as a ligature in order to retain an archwire in an archwire slot of the bracket.

摘要： A machined orthodontic bracket has a hook integrally formed with a gingival tiewing of the bracket. The hook includes a square shank, and a head with a cylindrical surface. The hook is machined by an end mill or formed cutter, and is achieved in part by changing the orientation of the bracket midway through the machining operation.

摘要： A ceramic bracket has mesial and distal sections that are initially spaced apart from each other by an elongated channel. The bracket is debonded from a patient's tooth at the conclusion of treatment by pivoting one or both of the mesial and distal sections in an arc about a reference axis extending in a direction generally parallel to the channel. The bracket includes a recess that extends across a base of the bracket in generally parallel relationship to the channel. The base of the bracket has an aspect ratio that is less than about 0.95 and enables the bracket to be debonded with less force than might otherwise be necessary.
