Description

Technical Field

[0001] The invention relates to an orthodontic treatment tooth restoration, and in particular to a method for manufacturing a tooth restoration combined with accessories and the tooth restoration. Background Art

[0002] Invisible braces are a modern orthodontic treatment method that uses three-dimensionally designed transparent aligners to gradually adjust the position of teeth to achieve neat alignment and improved bite.

[0003] Those skilled in the art will understand that various accessories are usually required during oral invisible orthodontic treatment. The accessories refer to small auxiliary devices that are part of the orthodontic appliance and are used to enhance the control and accuracy of the orthodontic appliance on the teeth. Common accessories include rectangular accessories, wedge-shaped accessories, optimized accessories, and the like.

[0004] For normal people, during the process of oral invisible orthodontics, a special orthodontic adhesive is applied to the tooth surface. Usually, a light-curing or chemically-curing resin adhesive is used. The accessories are placed on the adhesive with the aid of an accessory template and adjusted according to the designed position and direction.

[0005] The current problem is:

[0006] For patients who have received all-ceramic crown or veneer restorations, if they are given oral invisible orthodontics, since the surface of their dental restorations is all-ceramic and cannot be etched, it is difficult to achieve effective bonding if accessories are bonded to the surface of all-ceramic dental restorations, and the accessories are easy to fall off. Therefore, the original dental restorations need to be removed, and after the technicians have completed the transitional resin restorations, a new orthodontic treatment plan is formulated according to the patient's oral condition after the transitional restoration, and the orthodontic treatment is finally completed. This is very inconvenient for both doctors and patients. Patients need to return for multiple visits, including orthodontic treatment plan formulation, removal of original restorations, installation of temporary dental restorations, and formulation of new orthodontic treatment plans. Doctors need to complete the restoration production, restoration bonding, and accessory bonding processes in batches. These operations and follow-up visits greatly increase the patient's consultation time and the doctor's working time. Summary of the invention

[0007] The object of the present invention is to provide a method for manufacturing a dental restoration combined with accessories and a dental restoration, which can manufacture a temporary dental restoration combined with accessories in an integrated manner, thereby providing stable and reliable accessory support for orthodontic treatment.

[0008] In order to achieve the above technical objectives, the present invention adopts the following technical solutions:

[0009] A method for manufacturing a dental restoration combined with an accessory in an integrated manner, the method comprising: scanning the initial tooth arrangement form in the patient's mouth to obtain 3D scanning data of the initial tooth arrangement form; designing an orthodontic treatment plan for the patient based on the 3D scanning data of the initial tooth arrangement form, determining the accessories to be used, and determining the three-dimensional position and shape and size of the accessories on the teeth; designing an integrated accessory based on the initial tooth arrangement form to obtain 3D data of the tooth arrangement form including the accessories; removing the original dental restoration on the patient's teeth, scanning the main body tooth arrangement form in the patient's mouth to obtain 3D scanning data of the main body tooth arrangement form; inputting the 3D data of the tooth arrangement form including the accessories and the main body tooth arrangement form into a computer, designing a temporary dental restoration based on the tooth arrangement form including the accessories and the main body tooth arrangement form, and then manufacturing a temporary dental restoration entity; and performing a post-processing fine finishing treatment on the temporary dental restoration.

[0010] Furthermore, the 3D data of the initial tooth arrangement form, the tooth arrangement form including accessories and the main body tooth arrangement form are saved in STL file format.

[0011] Furthermore, before scanning the tooth arrangement of the subject, the tooth subject is firstly refined.

[0012] Furthermore, the post-processing finishing treatment includes: placing the temporary tooth restoration in the patient's mouth for trial wearing; performing acid etching treatment on the temporary tooth restoration; and performing moisture isolation treatment on the temporary tooth restoration.

[0013] Furthermore, the integrated production method also includes: after the temporary tooth restoration combined with the accessories is bonded, the patient's oral cavity is scanned again to obtain a new stl file, and the new oral scan data is matched with a pre-established orthodontic treatment plan to complete the design of the invisible braces; after the orthodontic treatment is completed, the temporary tooth restoration in the patient's mouth is removed, and a formal all-ceramic crown or veneer restoration is performed.

[0014] A tooth restoration temporarily used for orthodontic treatment, wherein the tooth restoration is made by adopting the above-mentioned integrated manufacturing method, and the tooth restoration has integrated accessories.

[0015] Compared with the prior art, the integrated manufacturing method of the present invention has the following beneficial effects:

[0016] In the integrated manufacturing method of the present invention, the digital design and computer-aided manufacturing methods of the prior art are used to integrally manufacture a temporary dental restoration combined with accessories. Before orthodontic treatment is performed on a patient with an all-ceramic dental restoration on his teeth, the above-mentioned temporary dental restoration is used to replace the original dental restoration on the patient's teeth, and then orthodontic treatment is performed. In this way, the situation of "accessories bonded to the surface of the all-ceramic dental restoration are easy to fall off" is avoided, thereby providing stable and reliable accessory support for subsequent orthodontic treatment, reducing the number of follow-up visits and treatment time of patients, improving treatment efficiency, and improving the patient's medical experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described below with specific embodiments:

[0019] This embodiment provides a method for integrated production of a dental restoration combined with accessories, which can produce a temporary dental restoration combined with accessories in an integrated manner, thereby providing stable and reliable accessory support for orthodontic treatment.

[0020] It should be noted that the integrated manufacturing method of this embodiment is targeted at patients who have received all-ceramic crown or veneer restorations.

[0021] See also Figure 1 The integrated manufacturing method of this embodiment mainly includes the following steps S1 to S5.

[0022] S1, for patients who have received all-ceramic crown or veneer restoration, use existing oral scanning equipment to scan the tooth arrangement in the patient's mouth, obtain and record 3D scanning data of the tooth arrangement.

[0023] For the convenience of description, the tooth arrangement at this time is referred to as the "initial tooth arrangement".

[0024] It should be noted that the initial tooth arrangement form is essentially the tooth arrangement form including the original tooth restoration.

[0025] It should be noted that, in this embodiment, the 3D scan data obtained by scanning is saved in STL file format. In the process of designing and manufacturing the restoration and its accessories, the STL format file is convenient for subsequent digital design, modification and manufacturing steps. Files in this format can be edited by CAD software, or directly used in manufacturing processes such as 3D printing or milling.

[0026] S2, input the 3D scanning data obtained in step S1 into the computer, use professional 3D modeling software, and design an orthodontic treatment plan for the patient based on the initial tooth arrangement form, determine the accessories to be used, and determine the three-dimensional position and shape and size of the accessories on the teeth; then in the 3D modeling software, integrate the determined accessories into the initial tooth arrangement form, so as to construct a tooth arrangement form including accessories based on the initial tooth arrangement form, and obtain the corresponding 3D data; the 3D data of the tooth arrangement form including accessories is saved in the form of an STL format file.

[0027] In summary, in step S2, according to a pre-established orthodontic treatment plan, integrated accessories are designed based on the initial tooth arrangement form, thereby obtaining 3D data of the tooth arrangement form including the accessories.

[0028] S3, remove the original all-ceramic crowns or veneer dental restorations on the patient's teeth, and then use the oral scanning device to scan the tooth arrangement state "after removing the original dental restorations" in the patient's mouth again, and obtain and record the 3D scanning data of the tooth arrangement morphology "after removing the original dental restorations".

[0029] The 3D scanning data obtained by scanning is still saved in STL file format.

[0030] For the convenience of description, the tooth arrangement at this time is referred to as the "original tooth arrangement".

[0031] It should be noted that before scanning the tooth arrangement of the subject, the tooth subject may be refined first.

[0032] S4, input the 3D data of the tooth arrangement morphology including the accessory teeth and the main body teeth obtained in step S2 into the computer, and then use professional 3D modeling software to design a temporary tooth restoration according to the tooth arrangement morphology including the accessory teeth and the main body teeth, and then use existing technical equipment to produce the temporary tooth restoration entity.

[0033] It should be noted that the temporary tooth restoration is actually a replica of the original tooth restoration, and its basic configuration is consistent with the original tooth restoration. However, compared with the original tooth restoration, it is combined with integrated accessories.

[0034] S5, for the temporary tooth restoration obtained in step S4, perform some post-processing routine procedures on the temporary tooth restoration, such as:

[0035] 1) Place the temporary dental restoration in the patient's mouth for trial wearing.

[0036] 2) Acid etching of the temporary tooth restoration,

[0037] 3) Protect temporary tooth restorations from moisture.

[0038] For the convenience of description, some of the above-mentioned post-processing routine processes are referred to as "post-processing finishing".

[0039] At this point, a temporary dental restoration combined with accessories is produced.

[0040] The integrated manufacturing method of this embodiment further includes the following steps S6 and S7.

[0041] S6, after the bonding of the temporary tooth restoration with accessories is completed, the patient's oral cavity is scanned again to obtain a new stl file, and the new oral cavity scan data is matched with the orthodontic treatment plan formulated in step S2, thereby completing the design and production of the invisible braces.

[0042] S7, after the orthodontic treatment is completed, the temporary dental restorations in the patient's mouth are removed and formal all-ceramic crowns or veneers are performed.

[0043] In the integrated manufacturing method of this embodiment, the digital design and computer-aided manufacturing methods of the prior art are used to integrally manufacture a temporary tooth restoration combined with accessories.

[0044] Before orthodontic treatment for patients who have received all-ceramic crowns or veneers, the above-mentioned temporary dental restorations are used to replace the original dental restorations on the patient's teeth, and then orthodontic treatment is performed. In this way, the situation of "accessories bonded to the surface of all-ceramic dental restorations are easy to fall off" is avoided, thereby providing stable and reliable accessory support for subsequent orthodontic treatment. In addition, the number of follow-up visits and treatment time of patients are reduced, the treatment efficiency is improved, and the patient's treatment experience is improved.

[0045] It should be noted that the present embodiment also provides a temporary dental restoration for orthodontic treatment, the dental restoration is manufactured by the above-mentioned integrated manufacturing method, and the manufactured dental restoration has integrated accessories.
