Problems solved by technology

This allows for a reduction in height and makes it possible to use the device for treatment in the mandible of many patients, but limits the functionality of the device for overall setback of the dentition as rotation of the mesial element relative to the distal element and spherical The corresponding collision point of the member or arm with the receiver
Therefore, these devices have limited ability to adjust the position of the molars in both "upright" and twisted positions

Embodiment Construction

[0035] Figure 1a The arrangement of the teeth in the lower jaw (mandible) is schematically shown. The anterior portion 110 of the oral cavity may be referred to as the mesial region. The posterior portion 120 of the oral cavity may be referred to as the distal region. The inner portion 130 of the mouth behind the teeth may be referred to as the lingual area. The outer portion 140 of the oral cavity may be referred to as the labial region. The mesio-distal direction 115 with respect to a particular tooth (first molar) has been indicated schematically in Fig. 1 . Also indicated in FIG. 1 is the lingual-labial direction 135 relative to the same tooth. This terminology will be followed throughout this disclosure.

[0036] Figure 1b Molar teeth are schematically shown. The mesial side of the molar is indicated by reference sign 110 and the distal side of the molar is indicated by reference sign 120 . Reference numerals 130 and 140 indicate the lingual and labial sides of th...

Abstract

An orthodontic device for the segmental distalization of a posterior jawbone area is disclosed. The orthodontic device comprises a mesial element having a mesial base surface for attachment to a premolar or a canine, a projection for coupling with a traction element, and an arm comprising an elongate transverse pin at a distal end of the arm, and a distal base having a distal base surface configured for attachment to a molar, and a receptacle for receiving the transverse pin. A first axis is defined as being substantially perpendicular to the distal base surface, and the transverse pin has a mesial surface and a distal surface, an interior shape of the receptacle is such that the rotation about the first axis is limited by the mesial and / or distal surface touching against an inside of thereceptacle. The disclosure also relates to orthodontic kits.

Description

[0001] This application claims the benefit of European Patent Application EP 17382306.3 filed on May 29, 2017. technical field [0002] The present application relates to orthodontic devices / orthodontic devices, and more particularly to orthodontic devices for segmental distalization of the posterior jaw segment. Background technique [0003] Depending on the patient's malocclusion, a variety of orthodontic treatments are available. During some of these treatments, teeth may need to be extracted to create room for the remaining teeth. In some treatments, integral setback elements of the dentition may be used, possibly in conjunction with extraction of one or more teeth. [0004] A segment of teeth is defined herein as a group of adjacent teeth, ie two or more adjacent teeth. Segmental dentition global setback of teeth involves moving a group of teeth together. In particular, in the present disclosure, a global setback of the dentition refers to moving a group of teeth in ...
