Pressed film base suitable for production of bracket-free invisible appliance and pressing method

Abstract

The invention relates to the technical field of medical auxiliary equipment, in particular to a pressed film base suitable for production of a bracket-free invisible appliance and a pressing method. The pressed film base comprises a pressed film base main body and a tooth resin model, wherein a mounting clamping position is fixedly mounted in the center of the bottom of the pressed film base mainbody; two groups of positioning clamping positions are symmetrically and fixedly mounted at the top of the pressed film base main body, annular ventilation rings are uniformly distributed at the edgeof the pressed film base main body, a frosted layer surface is arranged at the top of the pressed film base main body, and a positioning clamping groove is formed in the bottom of the tooth resin model; and the tooth resin model is fixedly connected with the film pressing base main body through the positioning clamping groove and the positioning clamping positions. According to the pressed film base suitable for production of the bracket-free invisible appliance and the pressing method, air around the tooth resin model flows out and is discharged uniformly in all directions through treatment of the frosted layer surface, so that the situation that the deformation of the tooth resin model in the pressed film link is affected due to gas pressure generated by gas flow velocity difference is avoided.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a pressure film base suitable for invisible aligners without brackets and a pressing method. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to the health and beauty of teeth. The technology of invisible orthodontics without brackets is rapidly emerging and developing. Product manufacturers need to provide solutions and suppress invisible orthodontics suitable for each stage. Appliances, so the demand for invisible appliances is also increasing. [0003] The existing invisible aligner laminating technology is to put the bottom of the tooth model after three-dimensional rapid prototyping into the dental laminating machine, and the polymer diaphragm used for pressing the aligner is heated in the laminating machine, and then the diaphragm is covered with air pressure.

Problems solved by technology

[0003] The existing invisible aligner laminating technology is to put the bottom of the tooth model after three-dimensional rapid prototyping into the dental laminating machine, and the polymer diaphragm used for pressing the aligner is heated in the laminating machine, and then the diaphragm is covered with air pressure. On the 3D rapid prototyping model, but based on the fact that this technical field is in the initial stage, the specifications of the laminating machines provided by various equipment manufacturers are different, and the properties of the 3D rapid prototyping materials are different. The uneven positive pressure, the thermal deformation of the 3D rapid prototyping tooth model, and the loss of precision of the 3D rapid prototyping model will have a serious impact on the precision of the final invisible aligner, which will not only greatly reduce the treatment effect, but also seriously It can make the aligner unable to be worn in the patient's mouth, and even produce wrong corrective effect, resulting in medical accidents. Therefore, a kind of film base and pressing method suitable for the production of invisible aligners without brackets is designed, which is suitable for the current medical auxiliary equipment technical field is urgently needed
