Description
Technical Field
The invention belongs to the technical field of orthodontic tooth correction, and particularly relates to a manufacturing method of an invisible appliance occlusal pad.
Background
In the orthodontic treatment process, for the case with the anti-occlusion or other occlusion interference of teeth, according to the degree of occlusion interference, the fixed correction can adopt temporary occlusion rise by a small amount of glass ions or blue gel; for patients with large occlusion interference, the retention snap ring bent by the stainless steel wire and the denture base material can be used for manufacturing the tooth combination cushion for auxiliary treatment in the correction process. However, the bracket-free invisible orthodontic appliance used for treatment is a conventional occlusal pad with a snap ring and cannot be retained in the mouth, so in the prior art, some bracket-free invisible orthodontic technologies adopt occlusal pad accessories to raise occlusion, but the preformed occlusal pad accessories have single shape and limited height, and the occlusal pad accessories have higher dropping rate in the process of taking off and wearing the appliance, thereby influencing the orthodontic process; some orthodontists can choose to use the self-setting denture base material to line the occlusal surface of the invisible appliance to manufacture the occlusal pad, but the invisible appliance without the bracket has a long correction period, and the new appliances need to be replaced in sequence every 1-2 weeks, and in the process, the manufacturing of the occlusal pad increases huge workload for the doctors.
The Chinese patent application with the application number of 202111367425.2 discloses a method for manufacturing an occlusal pad, wherein a silicon rubber impression technology is adopted, the occlusal pad can be manufactured on a plurality of pairs of orthodontic devices when a patient is subjected to a re-diagnosis, although the technology does not need to adjust and grind occlusion of each pair of orthodontic devices, each pair of orthodontic devices still need to be pre-ground and self-setting denture base material is re-lined, the workload of doctors is still large, and the silicon rubber impression can not be attached to each pair of orthodontic devices; in addition, the self-setting resin base material is re-lined on the surface of the bracket-free invisible appliance, and a certain shedding rate also exists in the using process of a patient, so that the correction effect is influenced.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention aims to provide a method for manufacturing an occlusal pad of an invisible appliance, which comprises the steps of manufacturing a pre-occlusal pad on an occlusal surface of a tooth position needing to be manufactured so as to lift occlusion, then acquiring a three-dimensional digital model in a mouth of a patient, submitting three-dimensional digital model data to a manufacturer, customizing the invisible appliance and obtaining the invisible appliance integrating the occlusal pad and the appliance.
In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:
a manufacturing method of an occlusal pad of an invisible appliance specifically comprises the following steps:
step one, preparation work is carried out;
step two, mixing the glass ionomer cement into a dough shape;
step three, manufacturing a pre-occlusion cushion 1;
and step four, manufacturing the bracket-free invisible orthodontic appliance integrating the occlusal pad and the orthodontic appliance according to the pre-occlusal pad 1.
The specific method of the first step is to pre-treat the teeth position which needs to be made into the occlusal pad to lift occlusion: drying and moisture-proof the occlusal surface of the tooth; drying the occlusal surface of the tooth position to be occluded by the occlusal pad, placing cotton balls under the tongue and on the buccal and lingual sides of the tooth position for drying and moisture insulation.
The specific method of the second step is as follows: according to the technical requirements of the clinical stirring of the glass ion cement, the glass ion cement is stirred to be in a dough shape.
The third step is specifically as follows: placing the glass ion cement prepared and mixed in the step two on the occlusal surface of the teeth dried in the step one, slightly pressing and finishing the mixture by using an alcohol cotton ball for forming, advising a patient to slightly bite when the glass ion cement is about to solidify, observing the occlusion opening degree of the teeth with occlusion interference, controlling the distance between upper and lower teeth to be 0-1mm, and if the distance is less than 1mm, mixing the glass ion cement again and adding the glass ion cement to the occlusal surface of the teeth; if the thickness exceeds 1mm, the redundant glass ion materials are removed by grinding, and the teeth are ensured to be uniformly contacted with the glass ion cement; in addition, redundant glass ion cement is ground off on the buccodental side of the teeth, and the shape of the pre-occlusion pad 1 is trimmed; thus, the pre-occlusal pad 1 is manufactured;
the concrete method of the fourth step is as follows: according to the tooth closes 1 preparation tooth of filling up in advance and fills up and the stealthy ware 2 of rescuring of no support groove of ware integral type: after the pre-occlusion cushion 1 is manufactured, three-dimensional digital model acquisition is carried out in the mouth of a patient, and the invisible appliance 2 is manufactured according to the three-dimensional digital model data.
Compared with the prior art, the invention has the beneficial effects that:
1. the method for manufacturing the invisible orthodontic appliance by acquiring the intraoral three-dimensional digital model after the occlusal pad is directly manufactured in advance in the mouth of the patient can be used for producing the bracket-free invisible orthodontic appliance integrating the occlusal pad and the orthodontic appliance, and the operation method is simple and is easy to master.
2. In the process of manufacturing the occlusal pad, a doctor only needs to adjust the shape, the height and the occlusion in the process of manufacturing the pre-occlusal pad 1, and compared with the mode of manufacturing the occlusal pad by using self-setting denture base materials for the traditional invisible appliance, the invention does not need to polish, fill and occlude each pair of appliances, thereby greatly reducing the workload of the doctor and improving the working efficiency of the doctor.
3. According to the bracket-free invisible orthodontic device, other materials are not required to be added on the orthodontic device, the risk of falling of the occlusal pad is not required to be considered, repeated consultation of a patient due to falling of the occlusal pad is avoided, the time of the patient is saved, and the satisfaction degree of the patient is improved.
4. The method is not only suitable for manufacturing the occlusal pad in the bracket-free invisible correction process, but also can be used for adding other auxiliary devices, and the method can be used for operating the upper jaw or the lower jaw in the manner, so that the application range is wide.
5. The shape and the height of the occlusal pad of the invention are controllable and adjustable, and can be adjusted according to the specific treatment requirements of different patients, thus having higher practicability.
