Problems solved by technology

[0006] First, for patients with abnormal tooth shape, no undercut or insufficient undercut, the retention is poor and the effect is not good
[0007] Second, compared with the permanent teeth, the tooth shape of the deciduous dentition is shorter and the crown is smaller, and the undercut is not obvious, so the retention of the deciduous dentition is poor, and the orthodontic effect is not good;
[0008] Third, the method of bonding and fixing the movable appliance and the teeth, because the patient cannot take off and wear the appliance, and cannot wash the appliance, it is impossible to keep the appliance clean and maintain oral hygiene
And affect the aesthetics of the patient

Embodiment 1

[0018] A design method for an orthodontic active appliance retaining device, comprising the steps of:

[0019] First, prepare the retaining attachment on the teeth. The specific method is: make a retaining attachment with a length of 1 mm, a width of 1 mm, and a height of 0.5 mm on the tooth with a filling resin material;

[0020] Second, remake the plaster model of the teeth in the mouth. The specific method is: first take the impression of the teeth in the mouth with dental silicone rubber material, and then pour the plaster model on the impression with gypsum.

[0021] Third, make removable appliances on the plaster model made in the previous step. The specific method is: use self-curing tray powder and self-setting tray water to make a removable appliance base, and the base covers the plaster model. Retaining accessories. At this time, the removable appliance base forms a groove in the same size as the retention attachment at the position of the retention attachment of th...

Embodiment 2

[0024] A design method for an orthodontic active appliance retaining device, comprising the steps of:

[0025] First, prepare the retaining attachment on the teeth. The specific method is: make a retaining attachment on the tooth with a length of 1.5mm, a width of 1.5mm, and a height of 0.8mm with a filling resin material;

[0026] Second, remake the plaster model of the teeth in the mouth. The specific method is: first take the impression of the teeth in the mouth with dental silicone rubber material, and then pour the plaster model on the impression with gypsum.

[0027] Third, use the retaining accessories to make removable appliances on the model made in the previous step. The specific method is: use the polymer material of the orthodontic die holder to make the removable appliance base, and the base is covered and reproduced on the plaster model retention accessories. At this time, the removable appliance base forms a groove in the same size as the retention attachment a...

Abstract

The invention relates to a design method of a positioning device of an orthodontic removable appliance, which comprises the following steps of: (1) preparing a retention accessory on teeth from dental filling resin; (2) preparing a tooth model in the mouth; (3) making the removable appliance on the model prepared in the previous step by utilizing the retention accessory, and thus, the removable appliance base forms a groove , the size of which is identical to that of the positioning accessory in the position of the tooth retention accessory in the mouth. The invention has the characteristics of simple operation, good positioning effect and attractive appearance.

Description

technical field [0001] The invention belongs to the technical field of orthodontics, and in particular relates to a design method of a retaining device for an orthodontic movable appliance. Background technique [0002] Orthodontics (orthodontics) is a branch of stomatology. Its subject content is to study the etiology, diagnosis, analysis, prevention and correction of malocclusion. Malocclusion refers to the deformity of teeth, jaw, and craniofacial caused by congenital genetic factors or acquired environmental factors, such as diseases, bad oral habits, abnormal tooth replacement, etc. during the growth and development of children, such as improper arrangement of teeth. Alignment, abnormal jaw relationship between the upper and lower dental arches, abnormal size, shape, and position of the jaw bone, etc. These abnormal mechanisms are tooth mass and bone mass, tooth and jaw, upper and lower dental arches. Incongruity between the upper and lower jaw, jaw and craniofacial. ...
