Description
Technical Field
The invention relates to the technical field of invisible correction devices, in particular to a manufacturing method of an invisible correction device.
Background
The invisible correction technology inherits the traditional dental deformity correction concept and is a perfect combination of modern stomatology, computer-aided three-dimensional diagnosis, personalized design and digital forming technology. Compared with the traditional dental deformity corrector, the invisible correction technology does not need brackets and steel wires, and adopts a series of invisible correction devices which are made of safe elastic transparent polymer materials, so that the correction process is almost completed in no perception of bystanders, and daily life and social contact are not affected. Meanwhile, the complicated processes of bonding brackets and adjusting archwires are avoided, the clinical operation is greatly simplified, and the whole correction process is time-saving and labor-saving.
The existing manufacturing method of the invisible appliance comprises the steps of firstly obtaining a dental data model of a patient, generating a stepwise correction data model through software simulation, obtaining a corresponding solid dental model through 3D printing and a rapid prototyping technology, pressing an orthodontic diaphragm into the invisible appliance through a method of excessive vacuum hot pressing, and finally delivering the orthodontic diaphragm to the patient for use after cutting and polishing. In the 3D printing manufacture, the material with highest precision is light-cured resin, so that the cost is high, the manufacturing cost of the invisible appliance is increased, and the precision still can reach 0.01mm.
Disclosure of Invention
The invention aims to solve the technical problems and overcome the technical defects, and provides a manufacturing method of the invisible appliance with high precision and reduced cost.
1. In order to solve the technical problems, the technical scheme provided by the invention is as follows: a method of manufacturing a concealed appliance comprising the steps of:
step 1: scanning the original dental jaw of a patient to extract corresponding three-dimensional dental jaw data;
step 2: constructing a corresponding digital model according to the three-dimensional dental data of the patient, and performing secondary treatment editing on the digital model and then performing virtual arrangement;
step 3: selecting corresponding epoxy resin blocks as raw materials according to the size and shape of the dental three-dimensional model;
step 4: cutting the epoxy resin block into a solid dental model and reserving a gum area through the control of a numerical control machine tool;
step 5: polishing the solid dental model obtained in the step 4;
step 6: pressing the heating diaphragm and the solid dental model in the step 5 to obtain an invisible appliance;
step 7: and (5) cutting and adjusting the gum part of the invisible appliance obtained in the step (6).
As an improvement, the secondary treatment editing in the step 2 mainly adjusts the region model to be corrected of the patient, and the operation can be performed by using Geomagic software.
As improvement, the processing error of the dental model is controlled to be less than or equal to 0.005mm.
As an improvement, the epoxy resin is a glycidyl ester type epoxy resin.
As an improvement, the surface roughness of the polishing appliance in the step 5 is less than or equal to 0.1.
As an improvement, the invisible appliance in the step 6 is soaked and sterilized after being adjusted.
Compared with the prior art, the invention has the advantages that: the manufacturing accuracy of the entity dental model is improved to 0.005mm in the application to make the stealthy appliance of preparing laminate patient's dental crown more, prevent to drop, prevent cladding gum through cutting the gingival area simultaneously, reduce the damage to gum nipple, carry out virtual arrangement through carrying out the secondary treatment to the digital model and edit the back in the application simultaneously and make things convenient for the doctor to adjust the model as required, thereby increase the therapeutic effect of appliance to the patient after wearing.
Detailed Description
A method of manufacturing a concealed appliance comprising the steps of:
step 1: scanning the original dental jaw of the patient to extract corresponding three-dimensional dental jaw data, and obtaining the original dental jaw data of the patient by using an intraoral three-dimensional scanner;
step 2: constructing a corresponding digital model according to three-dimensional dental data of a patient, performing secondary processing editing on the digital model, performing virtual arrangement, performing operation by using Geomagic software on the basis of the dental data prototype, constructing an original three-dimensional dental data model of the patient, and performing proper modification on the data model according to the requirements of doctors;
step 3: selecting corresponding epoxy resin blocks as raw materials according to the size and shape of the dental three-dimensional model;
step 4: cutting the epoxy resin block into a solid dental model and reserving a gum area through the control of a numerical control machine tool;
step 5: polishing the solid dental model obtained in the step 4;
step 6: pressing the heating diaphragm and the solid dental model in the step 5 to obtain an invisible appliance;
step 7: and (5) cutting and adjusting the gum part of the invisible appliance obtained in the step (6).
The secondary treatment editing in the step 2 is mainly used for adjusting a model of a region to be corrected of a patient, geomagic software can be used for operation, the processing error of the dental model is controlled to be less than or equal to 0.005mm, the error of the model is controlled during processing of the model in the step 3, the discomfort of wearing of a subsequent patient is reduced, the epoxy resin is glycidyl ester type epoxy resin, the production cost is reduced by adopting the glycidyl ester type epoxy resin, meanwhile, the model is a recyclable material, the residual materials can be recycled after cutting is used, the edge line of the invisible appliance can be designed along the arc line of the gingiva by about 1mm to 2mm, because the gingiva is stimulated or damaged if the edge line is too close to the arc line of the gingiva, the fitting degree of the model is reduced if the edge line is too far, so that the dental socket is easy to fall off, the correction force is reduced, and the correction effect is reduced.
The surface roughness of the polished appliance in the step 5 is less than or equal to 0.1, the discomfort of wearing the manufactured invisible appliance by a subsequent patient is increased by controlling the roughness, and the invisible appliance in the step 6 is soaked and disinfected after being adjusted, so that infection is prevented when the oral cavity has wounds after disinfection.
The present invention and its embodiments have been described in detail, but not limited thereto, and those skilled in the art should appreciate that they can readily use the present invention without departing from the spirit and scope of the invention as defined by the appended claims.
