Description

Invisible orthodontic diaphragm with non-uniform thickness

Technical Field

The utility model belongs to the orthodontic field of tooth, concretely relates to stealthy just abnormal diaphragm of non-uniform thickness.

Background

With the pursuit of beauty and comfort in the orthodontic process, the invisible correction is more and more accepted and used by users. The invisible bracket-free orthodontic appliance is a movable orthodontic device made of transparent elastic materials and designed and manufactured by computer assistance, and consists of a series of orthodontic appliances, and the aim of straightening teeth is finally achieved through continuous small-range movement of the teeth. The membrane material commonly used by the appliance in the prior art has uniform thickness which is between 0.6 and 0.8 mm. Because of the inherent characteristics of the tooth shape and the diaphragm material thermal forming, the thickness of the incisor in the appliance made of the invisible orthodontic diaphragm with uniform thickness is thinner than the thicknesses of other places, so that the force application at the position is smaller, the actual movement and the design movement deviation at the position are larger and larger along with the lapse of the correction time, and the correction efficiency and the wearing experience of the tooth socket are seriously influenced, therefore, the force application at the incisor in the appliance made of the invisible orthodontic diaphragm with uniform thickness cannot become one of the pain points in the industry. In addition, the power of should correcting in each place of the actual tooth of patient is not of uniform size, and the power that normal tooth needs is less, and the serious tooth that misplaces needs strength great, and even thickness diaphragm is unable to satisfy actual demand with correcting the ware, therefore needs an invisible orthodontic diaphragm of uneven thickness and corrects the ware urgently.

US6524101 provides a method of providing a non-uniform thickness invisible orthodontic appliance by placing a second diaphragm at different locations on a first diaphragm during thermoforming to provide a non-uniform thickness invisible orthodontic appliance. The chinese utility model patent CN201620747661.5 provides a double-layer tooth socket which can satisfy different stress requirements of different teeth. However, the non-uniform thickness membrane and the tooth socket provided by the two patents are separable, so that the wearing is troublesome, and the double-layer tooth socket is easy to separate, thereby affecting the actual correction efficiency.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem in the background art, the utility model provides an invisible orthodontic diaphragm with non-uniform thickness, which can satisfy the requirements of different teeth and improve the wearing experience, thereby avoiding the falling-off of the conventional double-layer tooth socket.

The utility model adopts the technical scheme as follows:

the invisible orthodontic diaphragm with the non-uniform thickness is non-uniform in thickness, the longitudinal section of the invisible orthodontic diaphragm is trapezoidal or nearly trapezoidal, and the nearly trapezoidal diaphragm is of a quadrilateral structure with one thick side and one thin side.

The cross section of the invisible orthodontic diaphragm is circular or square.

One or more bumps are arranged on the surface of the invisible orthodontic diaphragm.

The convex block is arranged at the position corresponding to the tooth with the correcting force needing to be strengthened.

The thickness of the invisible orthodontic diaphragm is 0.5-1.2 mm.

The invisible orthodontic diaphragm is made of one or more of PETG, TPU, PC, TPE, EVA and TPV.

The optical transmittance of the invisible orthodontic membrane is more than 75%.

One side of the invisible orthodontic diaphragm is matte, and the other side of the invisible orthodontic diaphragm is highlight.

The invisible orthodontic diaphragm is of an integrated forming structure.

The utility model has the advantages that:

the utility model discloses an invisible orthodontic diaphragm is the integrated into one piece, according to actual conditions or the different thickness combination of interior commonality designable, consequently promoted when satisfying the different power demands of correcting of different teeth and worn experience, avoids the condition that conventional double-deck facing drops. The utility model discloses have good economic value, can use widely on a large scale.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

The invisible orthodontic diaphragm with the non-uniform thickness has the advantages of non-uniform thickness, trapezoidal or nearly trapezoidal longitudinal section, quadrangular structure with one thick side and one thin side, and circular or square cross section. The surface of the invisible orthodontic diaphragm is provided with one or more convex blocks which are arranged at the positions corresponding to teeth with the orthodontic force needing to be strengthened. The thicker part of the diaphragm corresponds to teeth needing larger correcting force, and the thinner part of the diaphragm corresponds to teeth needing smaller correcting force.

Fig. 5 shows a schematic diagram of a preparation method of the invisible orthodontic film, and the preparation method comprises the steps of mold design, colloidal particle preparation, colloidal particle drying and injection molding. Designing a mold: the mold for the membrane is designed according to the specific situation of the actual patient or according to the general situation existing in the industry. Preparing colloidal particles: preparing raw materials required by the invisible orthodontic film. Drying colloidal particles: the drying temperature of the colloidal particles is 50-110 ℃. Injection molding: the injection molding temperature is 150-250 ℃, the injection molding pressure is 110-160bar, and the injection molding speed is 50-99%.
