    Abstract: Bond strengths of orthodontic appliances are enhanced by applying heat to heat softenable projections of a bonding base of the appliance, and then moving outer portions of the projections in lateral directions to present overhanging regions. The overhanging regions provide undercut areas that mechanically interlock with adhesive when the appliance is bonded to a tooth and the adhesive hardens. The method is useful for plastic appliances as well as other appliances that are made of materials exhibiting thermoplastic characteristics during at least one phase of their manufacture.

    Abstract: Transfer apparatus is constructed for applying an orthodontic composition such as a bonding composition to selected areas of multiple teeth simultaneously. The selected areas of the teeth that receive the composition substantially correspond to areas of the teeth that subsequently receive orthodontic appliances. As a result, contact of the composition with other regions of the oral cavity such as the gingival tissue is avoided.

    Abstract: 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 in a generally buccolabial direction on the appliance that exceeds a certain minimum value. The minimum value is less than about one-half of the force required in the same direction to debond the appliance from the tooth, and thus reduces the likelihood that the appliance will unintentionally debond from the tooth during the course of orthodontic treatment.

    Abstract translation: 诸如支架或口腔管的矫正器具具有用于将弓丝保持在弓丝槽中的闩锁。 每当弓丝在器具上大体上积分方向施加超过一定最小值的力时,闩锁将从弓丝插槽释放弓丝。 最小值小于同一方向从牙齿脱离器具所需的力的大约一半,从而降低了矫正治疗过程中器具将无意中脱离牙齿的可能性。

    Abstract: A computer implemented method of orthodontic appliance selection includes providing data representative of one or more teeth of a patient and providing data representative of a set of orthodontic appliances. Each orthodontic appliance of the set of orthodontic appliances has an appliance parameter that varies from the other orthodontic appliances of the set. At least one geometrical parameter of the one or more teeth of the patient is determined using the data representative thereof. The geometrical parameter is compared to the data representative of the set of orthodontic appliances and one orthodontic appliance of the set is selected based on the comparison. The set of orthodontic appliances may be a set of orthodontic bands with each band of the set having a different size. Further, such bands may be precoated with an adhesive material. A computer readable medium tangibly embodying a program executable for use in selection of orthodontic appliances, a system for use in orthodontia using such selection, and a method of fitting an orthodontic band to a patient are also provided. Further, an article including a container and a set of precoated bands received therein is provided.

    Abstract: An orthodontic assembly includes one or more orthodontic brackets that are releasably received in a tubular carrier. The carrier has arms with outer end sections that are spaced apart from each other to present a channel therebetween. The outer end sections of the arms are received in occlusal and gingival recesses of each bracket in order to support the bracket in suspended relation. The carrier is particularly useful for holding brackets during a manufacturing operation or during transport of the brackets from manufacturing operation to another. The carrier is also useful for supporting brackets in a package for shipment to the end user, especially when the brackets are precoated with a layer of adhesive.

    Abstract: A package for an adhesive precoated dental appliance such as an orthodontic bracket includes a container having a well and a flange, and a cover that extends over an opening of the well. A pressure sensitive adhesive releasably connects the cover to the flange along a first region, and a hermetic seal extends between the cover and the flange along a second region that is located between the first region and the opening of the well. The hermetic seal cooperates with the pressure sensitive adhesive to provide a reliable, easily openable package. The hermetic seal also prevents volatile components of adhesive on the dental appliance from contacting the pressure sensitive adhesive and thereby decreases loss of the volatile components from within the package in order to extend the expected shelf life of the adhesive precoated appliance.
