Embodiment Construction

[0033] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] The structure of a 90-degree twist appliance for upper anterior teeth of the present invention is as follows: Figure 1-4 As shown, it includes the lingual buckle 2, the first labial traction hook 101, the second labial traction hook 102, the elastic rubber ring 3, the retaining device 5, the distal proximal surface guide plate 4 and the maxillary palatal side resin base 6;

[0035] The maxillary and palatal side resin base 6 is installed at the maxillary palate, the distal proximal surface guide plate 4 is arranged in the distal space of the twisted teeth, and the distal proximal surface guide plate 4 is connected with the maxillary and palatal side resin base 6 ;

[0036] like figure 2 As shown, the lingual buckle 2 is fixed on both sides of t...

Abstract

The invention discloses an upper anterior tooth 90-degree torsion appliance and a preparation method thereof, and belongs to the technical field of tooth correction. The upper anterior tooth 90-degreetorsion appliance comprises lip side traction hooks and a torsion tooth near distal tongue side buckle, wherein elastic rubber rings are arranged between the lip side traction hooks and the torsion tooth near distal tongue side buckle, a distal adjacent surface guide plate is arranged in a torsion tooth distal gap, and retention devices arranged on upper jaw molar teeth on two sides are arrow clamping rings. The lip side traction hooks and the arrow clamping rings are all embedded in an upper jaw palate side resin base support. The preparation method comprises the following steps: preparing an upper and lower jaw working model; trimming the working model; making the lip side traction hooks and a double-side rear tooth arrow clamping ring in a bending manner, making the resin base supportof the appliance through a novel injection molding process, enabling the arrow clamping rings and a traction hook tongue side to be embedded in the resin base support, and enabling the base support toextend to the distal end of a torsion tooth and form an integrated structure with the distal adjacent surface guide plate. The appliance prepared by the preparation method disclosed by the inventioncan efficiently solve the problem of severe torsion during eruption of the anterior teeth of a child, thoroughly avoids the situation that the torsion teeth do distal movement and lose tooth lacking gaps, and enables a child patient to wear comfortably.

Description

technical field [0001] The invention belongs to the technical field of orthodontics, and in particular relates to a 90-degree twisting appliance for upper anterior teeth and a preparation method thereof. Background technique [0002] Torsion of the upper anterior teeth is a common malocclusion in children, especially during the replacement dentition period. Clinically, there is a class of children with severe twisting when the upper anterior teeth erupt, such as a 90-degree twist. At this time, the lateral incisors have not yet fully erupted, and there will be a large gap far away from the twisted teeth. This kind of malocclusion not only affects the appearance of the child, but also because the twisted teeth do not have good occlusal contact with the mandibular teeth, occlusal trauma may occur, which affects the normal masticatory function and further affects the normal growth and development of the jaw. Therefore, for children with this type of malocclusion, early correct...
