Benefits of technology

[0011] The present invention is a significant advantage, in that the properties of the adhesive of each appliance may be tailored to help optimize bonding to different teeth in the oral cavity. For example, the adhesive associated with appliances for the posterior teeth may be softer or less viscous than the adhesive associated with appliances intended for the anterior teeth. Such an assembly may be preferred by some practitioners, since the posterior appliances often have a larger base than anterior appliances and consequently provide more resistance to firmly seating the base of the appliance against the tooth surface. Other examples are also possible.

Problems solved by technology

Obviously, such occurrences represent a nuisance for both the practitioner and the patient, and may also increase the treatment cost as well as the length of time needed for treatment.

Embodiment Construction

[0037]FIG. 1 illustrates an example of an oral cavity of an orthodontic patient that is undertaking orthodontic therapy. The patient has a first orthodontic brace 22 that is connected to the teeth of the upper dental arch 23 and a lower orthodontic brace 24 that is connected to the teeth of the lower dental arch 25. Each brace 22, 24 includes a set of orthodontic appliances along with an archwire that is received in slots of the appliances, as will be described in more detail below.

[0038]FIG. 2 is an enlarged view of the lower dental arch 25 along with the lower brace 24, looking in a downwardly direction toward the outer or occlusal tips of the teeth. The lower dental arch 25 includes a left quadrant 26 and a right quadrant 28. Each of the quadrants 26, 28 includes a central incisor tooth 30, a lateral incisor tooth 32, a cuspid tooth 34, a first bicuspid tooth 36 and a second bicuspid tooth 38. In addition, each of the quadrants 26, 28 includes a first molar tooth 40 and a second...

Abstract

An assembly for use in orthodontic treatment includes at least two articles, and each article includes an orthodontic appliance as well as an adhesive that extends across the base of each appliance. The adhesive of at least one article differs from the adhesive of at least one other article in terms of composition, properties or characteristics, such that the adhesive can be tailored to enhance the bond between the particular selected appliance and its intended tooth.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates to a packaged assembly of orthodontic appliances that are used in the patient's oral cavity during the course of orthodontic treatment. More particularly, the present invention relates to an assembly of orthodontic appliances having a quantity of adhesive that has been applied to the base of each appliance by the manufacturer. [0003] 2. Description of the Related Art [0004] Orthodontic treatment involves movement of malpositioned teeth to orthodontically correct positions. Tiny orthodontic appliances known as brackets are connected to exterior surfaces of the patient's teeth, and an archwire is placed in a slot of each bracket. The archwire forms a track to guide movement of the teeth to desired positions for correct occlusion. End sections of the archwire are often received in appliances known as buccal tubes that are fixed to the patient's molar teeth. In recent years it has become common pr...
