US Patent:

6350119, Feb 26, 2002

Filed:

May 8, 2000

Appl. No.:

09/567163

Inventors:

Russell A. Jordan - Rancho Cucamonga CA
James D. Hansen - Pasadena CA
Yang Zhu - St. Paul MN

Assignee:

3M Innovative Properties Company - St. Paul MN

International Classification:

A61C 300

US Classification:

433 23, 206396

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.

Appl. No.:

10/078970

Inventors:

James D. Hansen - Pasadena CA, US

Assignee:

3M Innovative Properties Company - St. Paul MN

International Classification:

A61C 7/00

US Classification:

433 18, 433148

Abstract:

An orthodontic separator, dimensioned such that it can be inserted between adjacent teeth. The separator is characterized in that it exhibits an increase in compressive force after insertion between adjacent teeth in the oral environment. The separator, after insertion, exerts sufficient force on the adjacent teeth to push the teeth apart.

International Classification:

A61C 3/00

US Classification:

433 9

Abstract:

The present invention provides multi-layer adhesives and methods that are useful for bonding orthodontic appliances to a tooth structure. The multi-layer adhesives can be precoated on an orthodontic appliance, or alternatively, they can be provided on an adhesive delivery system for transfer to an orthodontic appliance. The multi-layer adhesives and methods preferably provide a useful balance of properties for bonding orthodontic appliances to the tooth structure.

International Classification:

A61C019/04
A61C011/00

US Classification:

433/073000, 433/213000

Abstract:

A computer implemented method includes providing a first set of digital data corresponding to an upper arch image of at least a portion of an upper dental arch of a patient, providing a second set of digital data corresponding to a lower arch image of at least a portion of a lower dental arch of the patient, providing bite alignment data representative of the spatial relationship between the upper dental arch and the lower dental arch of the patient, and aligning the upper and lower arch images relative to one another based on the bite alignment data until an aligned upper and lower arch image is attained. The aligned upper and lower arch images are moved towards each other until a first contact point is detected and at least one of the upper and lower arch images is moved relative to the other in one or more directions to a plurality of positions for determining optimal occlusion position of the lower and upper dental arches.

Appl. No.:

9/150471

Inventors:

John S. Kelly - Arcadia CA
James D. Hansen - Pasadena CA
James D. Cleary - Glendora CA

Assignee:

3M Innovative Properties Company - St. Paul MN

International Classification:

A61C 300

US Classification:

433 20

Abstract:

An orthodontic archwire with a certain cross-sectional construction has a stiffness that is less than conventional archwires having identical overall dimensions. The archwire has four corner edge portions that provide control over torquing movements and uprighting movements of the associated teeth as may be needed during the course of orthodontic treatment. The archwire is particularly useful during the early stages of orthodontic treatment when an archwire of reduced stiffness is desired and yet control over torquing and uprighting movements of the associated teeth is sought. Optionally, the archwire includes an aesthetic coating with certain characteristics that enable the majority of the coating to remain intact and provide an improved overall appearance even if certain regions of the coating are damaged and removed.
