Examples

As shown in fig. 1-3, the membrane 100 of the present invention is used for preparing a shell-shaped dental appliance 200; specifically, the diaphragm 100 comprises a base diaphragm, at least one preset hole 101 is further formed in the base diaphragm, and information parameters of the preset hole 101 are set according to the correction plan, so that the diaphragm 100 is constructed into a shell-shaped dental appliance 200, and then the physical properties of increasing air permeability and gradually changing teeth of a patient from an initial position to a target correction position are achieved.

In a preferred embodiment of the present invention, the information parameter of the predetermined hole 101 includes position information and aperture size information, and/or further includes at least one of quantity information or distribution information. The more detailed the information parameters in the orthodontic plan, the more the corresponding predetermined holes can be fitted with the orthodontic plan, and finally the more the shell-shaped orthodontic appliance is constructed, the better the physical property expression rate of the teeth of the patient gradually changing from the initial position to the target orthodontic position is.

More specifically, the predetermined holes 101 may be designed according to the actual conditions in the patient's mouth and the correction scheme of the clinician, such as the preset position, the preset aperture size, the preset number and the distribution of the sticking lingual buttons on the teeth are set by using the predetermined holes 101. As shown in fig. 1, the predetermined holes 101 on the membrane 100 are similar to the arrangement shape of the dentition, wherein the preferred mode is that the predetermined holes 101 may be disposed on the lingual side or labial side of the corresponding shell-shaped dental appliance 200, and in the actual application process, the predetermined holes may be 1.5mm or 2mm in diameter, so as to provide corresponding traction hooks or brackets to be stuck on the lingual side or labial/buccal side after the shell-shaped dental appliance 200 is prepared, thereby achieving the dental appliance effect. As shown in fig. 2 and 6, the predetermined hole 101 of the membrane is arranged on the buccal side surface of the posterior dental area corresponding to the dentition, or as shown in fig. 2 and 8, the predetermined hole 101 of the membrane is arranged on the occlusal surface of the posterior dental area corresponding to the dentition, the predetermined hole 101 of the membrane 100 arranged thereon after the squeeze film operation forms the predetermined hole 201 of the shell-shaped orthodontic appliance 200, and the predetermined hole is arranged on the buccal side surface or the occlusal surface of the posterior dental area corresponding to the occlusal surface of the dentition, so that the air permeability can be increased on the premise of ensuring the orthodontic performance without affecting the aesthetic appearance. As shown in fig. 3 and 7, the predetermined holes 101 of the membrane 100 correspond to the predetermined holes 201 corresponding to the lingual side of the shell-shaped dental appliance 200 and are disposed on the lingual side of the anterior dental area, so that the ventilation property can be increased while ensuring the appliance performance, and the aesthetic appearance is not affected.

In an embodiment of the present invention, as shown in fig. 1 to 3, the position information is designed on at least one of the labial/buccal side, lingual side or occlusal surface side of the tooth according to the correction plan, wherein the specific selection form can be set according to the actual correction requirement. More specifically, the tongue side of the preset teeth in the correction plan is provided with the preset holes 101, the tongue side of the prepared shell-shaped dental appliance 200 is provided with corresponding preset holes 201, and the preset holes 201 are arranged on the tongue side of the shell-shaped dental appliance 200, so that the wearing attractiveness of a patient cannot be affected when the patient wears the shell-shaped dental appliance; in addition, when only the lip/buccal side of the shell-shaped dental appliance 200 is to be corrected, the predetermined hole 101 provided on the lingual side does not affect the corresponding correction effect, and the effects of increasing air permeability and being comfortable to wear can be achieved. In another setting mode, the predetermined holes 101 are arranged on the lip/buccal side of the preset teeth in the correction plan, the corresponding predetermined holes 201 are formed in the lip/buccal side of the prepared shell-shaped dental appliance 200, and the predetermined holes 201 are arranged on the lip/buccal side of the shell-shaped dental appliance 200; in addition, when only the lingual side of the shell-shaped dental appliance 200 is to be corrected, the predetermined holes 101 provided on the labial/buccal sides do not affect the corresponding correction effect, and the effects of increasing air permeability and being comfortable to wear can be achieved. In another setting mode, the occlusion surface side of the preset teeth in the correction plan is provided with the preset holes 101, the prepared shell-shaped dental appliance 200 has the corresponding preset holes 201 on the occlusion surface, and the preset holes 201 are arranged on the occlusion surface of the shell-shaped dental appliance 200, and in a more preferable embodiment, the preset holes 201 can be arranged in the posterior dental area, because the occlusion surface of the teeth in the posterior dental area has a larger area, the preset holes 101 are arranged on the preset holes, so that the attractiveness is not influenced, the friction force of the upper jaw and the lower jaw in contact can be increased, for special cases needing to keep the relative positions of the upper jaw and the lower jaw, the corresponding correction can be performed by adopting the mode, and meanwhile, the wearing comfort of patients is also increased. Of course, the setting of the above three modes can be set independently, and can also be set in combination according to the actual clinical requirement.
