Patent number: 9925025Abstract: Provided packaged orthodontic assemblies and methods compressively retain an orthodontic appliance in a container along opposing sides of the appliance adjacent the bonding surfaces of its base. This can be done using a mechanism that limits contact between the appliance and the container while accommodating a substantial range of transverse base dimensions. This engagement mechanism allows an adhesive-coated appliance to be retained in a consistent orientation for convenient dispensing, while limiting potentially adverse interactions between the adhesive and the container. By avoiding loss of the adhesive components during storage, these assemblies and methods can extend shelf life and provide consistent adhesive handling properties.Type: GrantFiled: November 21, 2016Date of Patent: March 27, 2018Assignee: 3M Innovative Properties CompanyInventors: Alan F.

Patent number: 7549860Abstract: A hand instrument for debonding an adhesively bonded orthodontic bracket from a patient's tooth includes two jaws, each of which includes a contact pad for engaging opposite sides of the bracket. When the jaws are moved together, at least a majority of the area of each contact pad that contacts the side of the bracket is located beneath the archwire slot of the bracket in a lingual direction in order to facilitate fracture of the adhesive bond and release of the bracket from the tooth surface.Type: GrantFiled: December 13, 2004Date of Patent: June 23, 2009Assignee: 3M Innovative Properties CompanyInventors: Philip P. Soo, Fay T. Salmon, John A. Verdouw, Ming-Lai Lai, James D. Clearly

Patent number: 6910884Abstract: An orthodontic appliance such as a bracket or buccal tube has an overall, low profile shape. The appliance includes a base having a thickness that is less in regions adjacent the archwire slot as compared to remaining regions. In certain embodiments, the base is provided with protrusions that extend into the archwire slot for controlling rotation of the associated tooth. The resulting low profile of the appliance enhances its aesthetic appearance and helps to avoid impingement of the appliance and the attached archwire on adjacent soft tissue in the oral cavity.Type: GrantFiled: December 19, 2002Date of Patent: June 28, 2005Assignee: 3M Innovative Properties CompanyInventors: John S. Kelly, Oliver L. Puttler, John A. Verdouw

Patent number: 6733285Abstract: An appliance used in orthodontic treatment includes a retaining groove that is located directly adjacent a base of the appliance. The retaining groove is useful for keeping a wire segment or other item in place and in contact with a body of the appliance so that the item does not detach from the appliance during the course of treatment. The retaining groove is particularly useful for keeping tieback loops and other items having a thread-like configuration in a captive, compact and snug relationship with the appliance.Type: GrantFiled: December 14, 2001Date of Patent: May 11, 2004Assignee: 3M Innovative Properties CompanyInventors: Oliver L. Puttler, John A. Verdouw

Patent number: 6709268Abstract: An appliance used in orthodontic treatment includes a retaining guide that extends outwardly in an occlusal and/or a gingival direction. The retaining guide presents a smoothly contoured, domed shape having a relatively low profile for avoiding contact with opposing dentition or orthodontic appliances that are connected to opposing dentition. The retaining guide is useful for keeping a wire segment or other item in place and in contact with a body of the appliance so that the item does not detach from the appliance during the course of treatment. The retaining guide is particularly useful for keeping tieback loops and other items made from wire segments in place.Type: GrantFiled: December 14, 2001Date of Patent: March 23, 2004Assignee: 3M Innovative Properties CompanyInventors: Jirina V. Pospisil, David E. Solid, Oliver L. Puttler, John A. Verdouw
