Embodiment Construction

[0012] according to Figure 1-Figure 3 The orthodontic appliance (1) comprises arcuate recesses (10, 20) for the teeth of the upper and lower jaws, ie an upper recess (10) and a lower recess (20). The upper and lower concavities (10, 20) of the instrument (1) are separated by an occlusally extending isthmus (30), the upper and lower inner walls (11, 21) of the concavities (10, 20) ) and upper and lower outer walls (12, 22) extend vertically from said isthmus. In the isthmus ( 30 ), in the region of receiving the incisors of the user of the instrument ( 1 ), a reinforcing element ( 40 ) is arranged, the material of which is harder than the material from which the actual instrument ( 1 ) is made.

[0013] exist Figure 1-Figure 3 In an embodiment of the invention, the reinforcing element (40) is arranged to extend vertically within the isthmus (30) of the instrument (1) so as to form a portion on the surface of the isthmus (30) for individual incisors. The reinforcing element...

Abstract

The invention concerns an orthodontic appliance made of elastic material and comprising arch- shaped upper and lower concaves (10, 20) for teeth of upper and lower jaw, the concaves (10, 20) being separated by an occlusally extending arch- shaped isthmus (30) and comprising inner (11, 21) and outer walls (12, 22) extending vertically from the edges of the isthmus (30). The appliance includes a volume (40) within the frontal section of the arch-shaped isthmus (30) of material harder than said elastic material and extending vertically in the isthmus (30) so as to form at least one section of a surface of the isthmus (30), so as to make up a biting surface (41, 42) on the upper side and the lower side of the isthmus (30).

Description

technical field [0001] The invention relates to an orthodontic appliance as defined in the preamble of claim 1 for guiding the occlusion of an individual. Background technique [0002] Orthodontic appliances typically include U-shaped or arcuate recesses for the teeth of both the upper and lower jaws. The upper and lower concave portions of the instrument are generally separated by an occlusally extending isthmus from which inner and outer walls extend vertically. For an individual's teeth, the isthmus may include a recess or void. Typical materials from which these devices are made include thermoplastic elastomers, plastified (softened) plastics, rubber, and similar elastic materials. [0003] Prior art orthodontic appliances include a variety of designs that may include details intended, for example, to aid in the overall function of the appliance, or to help heal an individual's malocclusion problem. [0004] Due to the properties of elastic materials, prior art instru...
