[0027] In order to enable those skilled in the art of the present technology to better understand the technical solutions in this application, the following will clearly and completely describe the technical solutions of the present utility model in conjunction with the drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts should fall within the scope of protection of this application.
[0028] Embodiment 1:
[0029] As Figures 1-4As shown in the figure, a dental repair mold for use with a bracketless invisible orthodontic appliance can prepare a corresponding repair model according to the shape of the occlusal cavity to be repaired. During repair, the repair model is filled into the occlusal cavity at one time, which can shorten the filling time. The structure adopted includes an outer dental appliance 2 and an inner dental appliance 1. The outer dental appliance is a hard dental appliance; the inner dental appliance 1 is a soft dental appliance, and a filling mold 102 is provided on the inner dental appliance 1. The filling mold 102 is provided with a model hole 1021, and the model hole 1021 matches the occlusal cavity 6 on the tooth 8; wherein, the outer dental appliance 2 is movably sleeved on the inner dental appliance 1; both the outer dental appliance 2 and the inner dental appliance 1 respectively match the dental arch in the oral cavity.
[0030] The outer dental appliance 2 is a transparent dental appliance. The material that can be used is a transparent polymer material, which is a commonly used material for existing bracketless invisible orthodontic appliances, has good chemical stability, slow rejection reaction, and has mechanical properties for long-term use.
[0031] The bottom surface of the outer dental appliance 2 is provided with an outer tooth impression 201 that matches the teeth on the dental arch in the oral cavity. This can facilitate it to be sleeved on the dental arch in the oral cavity.
[0032] The bottom surface of the inner dental appliance 1 is provided with an inner tooth impression 101 that matches the teeth on the dental arch in the oral cavity. This can facilitate it to be sleeved on the dental arch in the oral cavity.
[0033] The inner dental appliance 1 is made of latex or silicone. Both latex and silicone have softness. During filling, after the repair model is filled into the occlusal cavity on the patient's tooth at one time, the patient can gradually increase the biting force from slight to heavy. When the teeth bite, the outer dental appliance is sleeved on the inner dental appliance, playing a role in fixing the inner dental appliance, and then the inner dental appliance is fixed at the repaired position. Moreover, when biting, the teeth squeeze against the outer dental appliance through the inner dental appliance, and the teeth are in flexible contact with the inner dental appliance, reducing the pain and also facilitating the fixation of the repair model in the occlusal cavity through biting.
[0034] It should be noted that the filling mold 102 protrudes from the bottom surface of the inner dental appliance 1. The filling mold is used to limit the filling dental material to form a shape that matches the occlusal cavity 6. It can be understood that after the dental material is filled and formed, the filling mold 102 can be removed, which can reduce the influence of the mold on filling.
[0035] As Figures 1-3 As shown in the figure, the filling mold 102 includes a mold body 1022, and the mold body 1022 is provided with a model hole 1021 that matches the occlusal cavity 6.
[0036] The material filled in the model hole 1021 is the material used for repairing tooth damage.
[0037] The first filling material is composite resin. Composite resins are generally divided into two types: thermoplastic and thermosetting. The most common thermosetting resins are epoxy resin, phenolic resin, polyurethane, and aminoplastics. Composite resins have many advantages such as light weight, strong plasticity, short production time, environmental protection, corrosion resistance, recyclability, and long service life. They also have good effects on the restoration and filling of anterior and posterior tooth cavities.
[0038] The second filling material is glass ionomer cement. Glass ionomer cement has excellent chemical resistance, corrosion resistance, and good tensile strength. Its main component is polyvinylpyrrolidone-formaldehyde, and it is usually used for the caries cavities and fillings of primary teeth and deciduous teeth in children, and can play a role in tooth restoration.
[0039] The third filling material is amalgam. Amalgam can be used as a dental filling material, which can play a role in filling teeth, and has the functions of anti-bending and anti-impact. It also has stability, high strength, and good wear resistance.
[0040] Example 2:
[0041] Compared with Example 1, the difference is that: a preparation structure of the inner dental appliance is given, and an oral scanner 5, a computer 4, and a 3D printer 3 are additionally installed. The oral scanner 5 and the 3D printer 3 are both electrically connected to the computer 4. The oral scanner 5 scans the shape of the occlusal cavity 6 on the teeth in the oral cavity. The computer 4 is used to make a repair model 7 that matches the shape of the occlusal cavity 6. The 3D printer 3 is used to print the inner dental appliance 1 and the filling mold 102 thereon that matches the repair model.
[0042] According to the above embodiments, the working mode of the present utility model:
[0043] Use the oral scanner 5 to scan the patient's oral cavity to obtain a digital model of the patient's full dentition, that is, obtain the digital model of the inner dental appliance 1, and at the same time obtain the position of the tooth with the occlusal cavity, and scan the shape of the occlusal cavity, and transmit the scanned data information to the computer. A model is established in the design software on the computer, and then the model of the inner dental appliance and the repair model can be obtained. The computer then transmits the obtained model to the 3D printer 3. The 3D printer 3 performs 3D printing according to the received model data information. The printed inner dental appliance 1 is provided with a filling mold 102, and the model hole 1021 on the filling mold 102 matches the shape of the scanned occlusal cavity.
[0044] Fill the model hole 1021 with the filler required for repairing the tooth. After the filling is completed, the filling mold limits the filler to form a repair model 7. At this time, the filling mold can be removed, and the repair model 7 is aligned with the tooth occlusal hole to be filled and inserted at one time, and the inner brace 1 is put on the dental arch, and then the outer brace 2 is put on. The bite force can be from slight to heavy, and the inner brace 1 is limited and fixed by the outer brace 2, and the repair model is squeezed and fixed in the occlusal hole by the bite force. Then, the inner brace 1 and the outer brace 2 are removed, and the repair model is hardened by light exposure, and the outer brace 2 is worn on the corresponding dental arch. The outer brace can fix the teeth and prevent movement, which can further improve the firmness of the repair.
[0045] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
