Removable covering type invisible plane guide plate, invisible orthodontic device and manufacturing method of invisible plane guide plate and invisible orthodontic device

Abstract

The invention relates to a removable covering type invisible plane guide plate, an invisible orthodontic device and a manufacturing method of the invisible plane guide plate, the removable covering type invisible plane guide plate comprises a cavitation bubble type flat guide area and two-side retention areas, and the retention areas are used for wrapping and covering a conventional orthodontic appliance. The invisible orthodontic device comprises a transparent orthodontic appliance and a removable covering type invisible plane guide plate. The removable and wearable covering type invisible plane guide plate is compatible with an existing invisible correction system, can assist the existing invisible correction system to realize the correction purpose of occlusion opening, and does not influence the use of a conventional correction appliance; the cavitation bubble type flat guide area can provide a lower anterior tooth occlusion area with a large area, and for a deep occlusion patient, the back teeth can be effectively cushioned open, the occlusion contact force of the back teeth is eliminated, the back teeth are elongated, and the occlusion can be effectively opened; due to the design of the hollow three-dimensional parallel guide occlusal area, the hardness of the occlusal area is ensured, a certain elasticity and deformable range are provided, a patient can adapt to the occlusal area more easily, and the wearing feeling is more comfortable.

Description

Technical field [0001] The present invention relates to the field of invisible appliance technology, in particular to the removable cover invisible planar guide, invisible orthodontic device and production method thereof. Background [0002] In orthodontic treatment, the opening of the bite is achieved mainly by lowering the front teeth and / or elongation of the back teeth. In the traditional fixed orthodontic technique, for patients with steep Snap curves and deep anterior teeth overlay, when the elasticity of the straight arch wire is not enough to achieve occlusal opening, it is often used to open the bite with a rocking chair bow, step curve, auxiliary bow and so on on the bow wire. [0003] As a kind of aesthetic, hygienic and efficient orthodontic technology, the transparent orthodontic technology without brackets has been widely recognized by doctors and patients. In the invisible orthodontic technology, by drawing on the concept of rocking chair arch of traditional orth...

AI Technical Summary

Problems solved by technology

However, the effective rate of transparent aligners in incisor depression is only about 50%, and the elongation of posterior teeth is also the most difficult tooth movement method to achieve with transparent aligners, so it is difficult to open the occlusion

[0008] 3. The use of Bite Ramps is more limited: due to its small size, it is only suitable for patients with normal coverage or I degree deep coverage

Conventional BiteRamps are only suitable for patients with a coverage of less than 3mm. The widened version of BiteRamps can only achieve a occlusal range of 4-5mm. If the coverage of the patient exceeds the sagittal length of the BiteRamps, it will not only be difficult for the lower anterior teeth to bite the BiteRamps to achieve occlusal opening, but it may even easily cause Mandible is forced back

At the same time, since the Bite Ramps are directly set on the palatal side of the upper anterior teeth, on the one hand, it affects the wrapping of the upper anterior teeth braces, and on the other hand, it is equivalent to exerting vertical pressure on the palatal side of the upper anterior teeth. For the anterior teeth with poor torque It is unfavorable, and it is prone to side effects such as loss of anterior tooth torque and occlusal trauma
