Problems solved by technology

[0003] However, in the process of making invisible aligners or orthodontic retainers with dental films, since the current dental films are all of the same thickness, when the dental films are heated and then vacuum-absorbed, along with As the degree of tensile deformation increases, the thickness of the dental film in different areas where the tooth model is located is continuously reduced. The thickness of the finished product (invisible aligner or orthodontic retainer) may be uneven, and the thickness of the invisible aligner or orthodontic retainer (orthodontic appliance) may be uneven, which may lead to uneven correction force of the orthodontic appliance. Uniform, or lead to partial weakness and cracking of orthodontic appliances

Embodiment 1

[0028] Such as figure 1 As shown, the present invention is a partitioned dental film, the film surface of the dental film is provided with a direction indicator mark 1; The corresponding different positions on the membrane surface of the dental membrane divide the membrane into regions, and set different membrane thicknesses for different regions; the specific division method is as follows:

[0029] According to the corresponding longitudinal position of the tooth model on the membrane surface of the dental membrane, the membrane surface of the dental membrane is divided into the inside of the midline 2 and the outside of the midline 3; wherein, the midline 6 is a line connecting the upper and lower rows of teeth, and the midline The inner side 2 is the inner area of ​​a line where the upper and lower rows of teeth meet, and the outer side of the midline 3 is the outer area of ​​a line where the upper and lower rows of teeth meet; according to the corresponding lateral positio...

[0038] Such as figure 1 As shown, the present invention is a partitioned dental film, the film surface of the dental film is provided with a direction indicator mark 1; The corresponding different positions on the membrane surface of the dental membrane divide the membrane into regions, and set different membrane thicknesses for different regions; the specific division method is as follows:

[0039] According to the corresponding longitudinal position of the tooth model on the membrane surface of the dental membrane, the membrane surface of the dental membrane is divided into the inside of the midline 2 and the outside of the midline 3; wherein, the midline 6 is a line connecting the upper and lower rows of teeth, and the midline The inner side 2 is the inner area of ​​a line where the upper and lower rows of teeth meet, and the outer side of the midline 3 is the outer area of ​​a line where the upper and lower rows of teeth meet; according to the corresponding lateral positio...

Embodiment 3

[0051] The present invention is a partitioned dental diaphragm, which is made of three layers of different materials superimposed and formed by hot pressing, and a direction indicating mark 1 is arranged on the film surface, and according to the dental diaphragm during use The stress points are different, and the diaphragm is divided into regions according to the corresponding positions of the tooth model on the dental diaphragm, and different thicknesses are set for different regions. The method for dividing the membrane area and the thicknesses used in different areas are the same as those described in Embodiment 1.

[0052] The partitioned dental film has a three-layer structure, and each layer is made of different materials.

[0053] The manufacturing method of the partitioned dental diaphragm is as follows: firstly, three layers of different materials are stacked together, and hot-pressed to form a hot-pressed laminated diaphragm; then, a direction is made on the film sur...

Abstract

The invention discloses a partitioned dental membrane and a manufacturing method thereof. The surface of the partitioned dental membrane is provided with a direction indicator sign; according to the different stress-bearing points for stress which is born during the manufacture of a hidden correction device or an orthodontic retainer during usage of the partitioned dental membrane, the surface ofthe dental membrane is divided into four partitions according to different positions of a dental model on the surface of the dental membrane, namely a midline exterior incisor partition, a midline exterior molar partition, a midline interior incisor partition, and a midline interior molar partition; different membrane thickness is provided for each partition. The partitioned dental membrane can bemade into a product with different partitions' thickness kept uniform when applied to the manufacture of hidden correction devices or orthodontic retainers; the partitioned dental membrane enables corrective force to be expressed more evenly during correction with rarity of cracking.

Description

technical field [0001] The invention belongs to the technical field of orthodontic appliances, and relates to a dental diaphragm and a manufacturing method thereof, in particular to a partitioned dental diaphragm and a manufacturing method thereof. Background technique [0002] Dental diaphragms currently on the market mostly use a single-layer or multi-layer structure of a single material, and the thickness of the entire dental diaphragm is the same. Generally, dental films are used to make invisible aligners or orthodontic retainers. The method of making invisible aligners or orthodontic retainers with dental films is as follows: firstly, the tooth model is placed on the dental film; The diaphragm is heated; followed by vacuum forming, generally using vacuum force to stretch and deform the dental diaphragm sheet to make it into the shape of an invisible aligner or orthodontic retainer; finally cooling and forming. [0003] However, in the process of making invisible align...
