Abstract
Abstract An orthodontic method for treating malocclusion comprising the steps of forming a model of the patient's teeth in the form of a dental arch with the replicas of the teeth in idealized locations, establishing on the labial and buccal surfaces of the replicas locations which conjointly define an idealized dental arch configuration, forming rigid caps of hardenable, plastic material over the crowns of the replicas, affixing to the cap for each replica a bracket orientation module in registry with said established location and utilizing the caps with the respective bracket orientation modules to locate brackets on the corresponding teeth in the patient's mouth in locations corresponding to said established locations. Bracket orientation modules are provided which are usable to locate precisely brackets on the teeth at the outset of treatment and also to replace any lost or damaged brackets anytime during treatment.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
153 words
Apparatus for locating a bracket in a predetermined position on the labial or buccal surface of a tooth comprising a rigid cap having an internal shape conforming to the crown portion of a tooth, a hollow guide element fixedly secured relative to said cap and having an elongated guiding portion which extends transversely to and outwardly from the labial or buccal surface of the tooth with said guiding portion having one open end in registry with and spaced from the aforesaid predetermined position, the distance said open end is spaced from said predetermined position being greater than the height of a bracket to be mounted, a bracket-carrying member slidably received for rectilinear movement by said guiding portion whereby said member may be moved into registry with said predetermined position, and means on one end of said member for carrying a bracket and abutting the same against the tooth surface at said predetermined position.
Claim 2
Dependent Claim
153 words
Apparatus for locating a bracket in a predetermined position on the labial or buccal surface of a tooth comprising a rigid cap having an internal shape conforming to the crown portion of a tooth, a hollow guide element fixedly secured relative to said cap and having an elongated guiding portion which extends transversely to and outwardly from the labial or buccal surface of the tooth with said guiding portion having one open end in registry with and spaced from the aforesaid predetermined position, the distance said open end is spaced from said predetermined position being greater than the height of a bracket to be mounted, a bracket-carrying member slidably received for rectilinear movement by said guiding portion whereby said member may be moved into registry with said predetermined position, and means on one end of said member for carrying a bracket and abutting the same against the tooth surface at said predetermined position.
Claim 3
Dependent Claim
50 words
The apparatus of claim 1 wherein the guiding portion of said guide element has elongated surfaces that form a slide of uniform cross-section, said bracket-carrying member being shaped in cross-section slidably to engage said slide, the engageable portions of said element and member including shapes that prevent relative rotation thereof.
Claim 4
Dependent Claim
30 words
The apparatus of claim 2 wherein a portion of the end of said guide element which is in registry with said predetermined position is contiguously rigidly secured to said cap.
Claim 5
Dependent Claim
25 words
The apparatus of claim 1 including a supporting arm secured at one end to said guide element and at the other end to said cap.
Claim 6
Dependent Claim
77 words
The apparatus of claim 4 wherein said guide element is an elongated block with said slide being a channel formed therein, said supporting arm being secured to one side of said block and to the crown portion of said cap, said bracket-carrying member being in the form of an elongated plunger having a shape which slidably fits said channel, said member having a tongue projecting from one end thereof adapted to engage the slot of a bracket.
Claim 7
Dependent Claim
23 words
The apparatus of claim 5 wherein said channel is of keystone cross-section and said predetermined position is the mesialdistal portion of said tooth.
Claim 8
Dependent Claim
82 words
The apparatus of claim 3 wherein said guide element is in the form of a tube secured at said one end in a companion opening in the side of said cap, said bracket-carrying member being an elongated plunger of a cross-section that slidably fits the interior of said tube, and a key and slot connection between said element and member for preventing relative rotation thereof, said plunger having a tongue projecting axially therefrom and adapted to fit the slot of a bracket.
Claim 9
Dependent Claim
157 words
In a method of orthodontics for treating malocclusion, the steps of: (a) forming a model of the patient's teeth in the shape of a dental arch with the replicas of the teeth in idealized locations, (b) establishing on the labial and buccal surfaces, respectively, of said replicas locations corresponding to bracket slots, (c) forming rigid caps of hardenable plastic material over at least a portion of the crowns of preselected replicas in intimate conformity with the respective incisal edges, lingual, labial and buccal surfaces, said forming step including forming a single arch shaped cap over all of the replicas of said model, and sectioning said arch shaped cap into multiple caps, one for each replica, respectively, (d) securely affixing the guide portion of bracket-locating devices to said rigid caps, respectively, in registry with said established locations, and (e) utilizing the caps with the respective guide portions to locate brackets on the corresponding teeth in the patient's mouth.
Claim 10
Dependent Claim
