Description

Technical Field

[0001] The present invention relates to a tooth restoration technology, in particular to a temporary tooth restoration and a construction method thereof. Background Art

[0002] Orthodontics is a modern orthodontic method that uses three-dimensionally designed transparent appliances (invisible braces) to gradually adjust the position of teeth to achieve neat alignment and improved bite.

[0003] Those skilled in the art will understand that during oral correction, an appliance (usually referred to as an "invisible braces") is required, and the appliance requires a small device called an "accessory" during use.

[0004] "Attachments" are small devices bonded to the surface of teeth, typically made of a light-cured composite resin that matches the color of the teeth. Attachments serve two main functions: assisting with tooth movement and helping to retain the braces. Generally speaking, they enhance the control and precision of the braces.

[0005] Commonly used attachments include rectangular attachments, wedge-shaped attachments, optimized attachments, and so on.

[0006] For normal people, during oral orthodontic treatment, the tooth surface must first be acid-etched, and a special orthodontic adhesive is applied to the tooth surface. Usually, a light-curing or chemically-curing resin adhesive is used. The attachment is placed on the adhesive with the aid of an attachment template and adjusted according to the designed position and direction.

[0007] However, at present, the age structure of orthodontic patients is characterized by an increasing proportion of adult patients each year. These patients often have complex oral health conditions and have varying numbers of restorations in their mouths. For patients who have previously received crown restorations (including all-ceramic crowns, porcelain crowns, and metal crowns) or veneer restorations (i.e., patients with dental restorations installed on their teeth), oral orthodontic treatment is very difficult, as follows:

[0008] 1) Conventional dental restorations have ceramic or metal surfaces, which cannot be acid-etched according to conventional methods. In such cases, if accessories are bonded to the ceramic or metal surface of the dental restoration, effective bonding is difficult to achieve and the accessories are prone to falling off;

[0009] 2) Currently, hydrofluoric acid (a strong acid preparation) can also be used to etch the surface of the tooth restoration, but this process may cause harm to the patient.

[0010] 3) If the method of "directly bonding accessories to the dental restoration" is not adopted, the original dental restoration can also be removed. After the technician completes the production of a transitional resin restoration, a new orthodontic plan can be formulated based on the patient's oral condition after the transitional restoration, and the orthodontic operation can be completed. However, this approach is very inconvenient for both doctors and patients. The patient needs to return for multiple visits, including orthodontic plan formulation, removal of the original restoration, installation of temporary dental restorations, and formulation of a new orthodontic plan. The doctor needs to complete the restoration production, restoration bonding, and accessory bonding processes in multiple times. These operations and follow-up visits greatly increase the patient's consultation time and the doctor's working time.

[0011] 4) From the perspective of post-orthodontic restoration, the main issue involves the accuracy of the restoration. The existing methods have a large communication barrier between orthodontists (doctors who specialize in performing orthodontic surgery) and prosthodontists (doctors who specialize in making dental restorations): Specifically, because the prosthodontist's design requirements cannot be determined in advance, accurate post-operative restoration space is difficult to achieve. As a result, the orthodontist needs to repeatedly confirm and communicate with the prosthodontist, and during this communication process, the prosthodontist's estimate may also deviate, resulting in inconsistencies between the restoration space reserved for orthodontics and the space required for restoration, repeated coordination, increased treatment courses, or the need for the prosthodontist to compromise.

[0012] 5) From the perspective of the target position of orthodontic tooth movement, the existing technology is unable to obtain an orthodontic target position based on a healthy root-bone relationship. Many patients have problems such as malocclusion and protrusion that affect the aesthetic appearance of the teeth before restoration. During the previous anterior tooth restoration, the original aesthetic problems of the teeth have often been concealed and compensated through tooth preparation, restoration reshaping and other methods. If the restoration is not remade according to the original position, it will be impossible to align these restored teeth according to a reasonable root position, resulting in the inability to obtain a healthy root-bone relationship and the correction effect cannot reach the best.

[0013] 6) From the perspective of the social needs of adult patients, the rough temporary restorations used in the existing technology cannot meet the patients' aesthetic needs.

[0014] To sum up, the current problems are:

[0015] For patients with dental restorations in their mouths, the orthodontic process will encounter many difficulties as mentioned above, which will incur huge human and social costs for both doctors and patients. Summary of the Invention

[0016] One of the purposes of the present invention is to provide a temporary tooth restoration, which is used to replace the original tooth restoration in the patient's mouth, and then the patient undergoes subsequent orthodontic operation, thereby avoiding complicated operation procedures.

[0017] A second object of the present invention is to provide a method for constructing a temporary tooth restoration.

[0018] In order to achieve the above technical objectives, the present invention adopts the following technical solutions:

[0019] A temporary tooth restoration is provided, on which a tooth attachment coupling piece is integrally combined.

[0020] Furthermore, the temporary tooth restoration is used to be assembled on the patient's native teeth to replace the original tooth restoration, and then the patient receives subsequent orthodontic operation.

[0021] Furthermore, the tooth attachment coupling is an attachment, a bracket, a lingual buckle or a traction hook.

[0022] Furthermore, the bonding surface of the temporary tooth restoration is provided with an anti-caries coating.

[0023] A method for constructing a temporary dental restoration, the method comprising: S1, scanning the tooth arrangement form of a restoration in a patient's mouth to obtain 3D scanning data of the tooth arrangement form of the restoration; S2, based on the 3D scanning data of the tooth arrangement form of the restoration, designing an integrated tooth accessory combination on the basis of the tooth arrangement form of the restoration to obtain 3D data of the tooth arrangement form containing the tooth accessory combination; S3, removing the original dental restoration on the patient's teeth, scanning the native tooth arrangement form in the patient's mouth to obtain 3D scanning data of the native tooth arrangement form; S4, designing a temporary dental restoration based on the tooth arrangement form containing the tooth accessory combination and the native tooth arrangement form, and then producing a temporary dental restoration entity, wherein the temporary dental restoration entity is combined with the integrated tooth accessory combination.

[0024] Furthermore, the temporary tooth restoration construction method further comprises: S5, performing a post-processing fine finishing process on the temporary tooth restoration.

[0025] Furthermore, the temporary dental restoration construction method also includes: S6, assembling the prepared temporary dental restoration combined with the tooth attachment coupling on the patient's native teeth by bonding to replace the original dental restoration; S7, remaking a final restoration for the dental restoration patient, and after orthodontic treatment is completed, removing the temporary dental restoration in the patient's mouth and replacing the temporary dental restoration in the patient's mouth with the final restoration.

[0026] Furthermore, a guide is used during the assembly of the temporary dental restoration to achieve precise assembly.

[0027] Furthermore, the tooth attachment coupling is an attachment, a bracket, a lingual buckle or a traction hook.

[0036] The present invention will be further described below with specific embodiments:

[0037] See also Figure 1 This embodiment provides a temporary dental restoration. The innovation of the temporary dental restoration is that an accessory 2 for orthodontic operation is integrated into the temporary dental restoration 1, specifically, onto the outer surface of the temporary dental restoration 1.

[0038] The temporary dental restoration is used to be bonded and assembled on the patient's natural teeth to replace the original dental restoration, and then the patient undergoes subsequent orthodontic treatment. In this way, for patients undergoing dental restoration, the temporary dental restoration 1 of this embodiment can be used to replace the original dental restoration, and then the orthodontic plan can be implemented for the patient. This will avoid many difficult situations during the orthodontic process, and orthodontic planning will no longer be a hassle. For both doctors and patients, it can greatly reduce labor costs and social costs, thereby achieving good results.

[0039] It should be noted that the material used for the temporary tooth restoration 1 is a resin material, that is, the temporary tooth restoration 1 body and the attachment 2 are made of an integrated resin material.

[0040] In order to realize the above-mentioned temporary tooth restoration, the present embodiment further provides a temporary tooth restoration construction method, which integrally manufactures and constructs a temporary tooth restoration combined with accessories, providing stable and reliable accessory support for orthodontic operations.

[0041] It should be noted that the temporary dental restoration construction method of this embodiment is targeted at patients who have undergone crown restoration or veneer restoration (i.e., have dental restorations in their mouths). For the sake of convenience, such patients are defined as "dental restoration patients."

[0042] See also Figure 2 The temporary tooth restoration construction method mainly includes the following steps S1 to S7.

[0043] S1, for patients undergoing dental restoration, uses existing oral scanning equipment to scan the tooth arrangement in the patient's mouth, and obtains and records 3D scanning data of the tooth arrangement.

[0044] For the sake of convenience, the tooth arrangement at this time is defined as "prosthetic tooth arrangement".

[0045] It should be noted that the tooth arrangement form of the restoration is actually the tooth arrangement form including the original tooth restoration in the oral cavity of the dental restoration patient.

[0046] It should be noted that in this embodiment, the 3D scan data obtained by scanning is saved in the STL file format. During the design and manufacture of restorations and their accessories, STL files facilitate subsequent digital design, modification, and manufacturing steps. Files in this format can be edited in CAD software or directly used in manufacturing processes such as 3D printing or milling.

[0047] S2, inputting the 3D scanning data of the restoration tooth arrangement morphology obtained in step S1 into the computer, using professional 3D modeling software, and designing an orthodontic operation plan for the patient based on the restoration tooth arrangement morphology, determining the accessories to be used, and determining the three-dimensional position and shape and size of the accessories on the teeth; then, in the 3D modeling software, the determined accessories are integrated into the restoration tooth arrangement morphology, thereby constructing the tooth arrangement morphology including the accessories based on the restoration tooth arrangement morphology, and obtaining the corresponding 3D data; the 3D data of the tooth arrangement morphology including the accessories is saved in the form of an STL format file.

[0048] In summary, in step S2, according to a pre-established orthodontic operation plan, integrated accessories are designed based on the tooth arrangement of the restoration, thereby obtaining 3D data of the tooth arrangement including the accessories.

[0049] S3, remove the original all-ceramic crowns or veneers on the patient's teeth, and then use the oral scanning equipment to scan the "original tooth arrangement status after removing the original tooth restoration" in the patient's mouth again, and obtain and record the 3D scanning data of the "tooth arrangement form after removing the original tooth restoration".

[0050] The 3D scanning data obtained by scanning is still saved in the stl file format.

[0051] For the sake of convenience, the tooth arrangement at this time is defined as "original tooth arrangement".

[0052] It should be noted that before scanning the original tooth arrangement, the original tooth body can be refined first.

[0053] S4, input the 3D data of "the tooth arrangement morphology including accessories obtained in step S2" and "the native tooth arrangement morphology obtained in step S3" into the computer, and then use professional 3D modeling software to design a temporary tooth restoration based on the tooth arrangement morphology including accessories and the native tooth arrangement morphology, and then use existing technical equipment to produce the temporary tooth restoration entity.

[0054] 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 in the patient's mouth. However, compared with the original tooth restoration, it is combined with integrated accessories.

[0055] S5, for the temporary dental restoration obtained in step S4, perform some subsequent conventional processing procedures on the temporary dental restoration, such as:

[0056] 1) Place the temporary dental restoration in the patient's mouth for trial wear.

[0057] 2) Acid etching of the temporary tooth restoration,

[0058] 3) Protect the temporary tooth restoration from moisture.

[0059] For the convenience of description, some of the above-mentioned post-processing routines are referred to as "post-processing finishing."

[0060] S6, the prepared temporary tooth restoration combined with accessories is assembled on the patient's native teeth by bonding to replace the original tooth restoration. After that, the patient's oral cavity is scanned again to obtain new 3D scanning data, which is saved as an stl file. The new oral 3D scanning data is matched with the orthodontic operation plan formulated in step S2, thereby completing the design and production of the braces.

[0061] S7, remake the final restoration for the dental restoration patient. After the orthodontic treatment is completed, remove the temporary dental restoration in the patient's mouth and replace it with the final restoration.

[0062] The temporary tooth restoration and its construction method of this embodiment have the following advantages:

[0063] By using the temporary dental restoration and its construction method of the present embodiment to implement orthodontic plans for dental restoration patients, many difficult situations will be avoided during the orthodontic process, and orthodontic plans will no longer be a hassle. Both for doctors and patients, it can greatly reduce labor costs and social costs, thereby achieving good results.

[0064] Specifically,

[0065] 1) Ensure a good connection between accessories and temporary restorations, solving the problem of accessory retention. This includes all types of accessories that need to be connected: resin accessories for invisible correction, brackets for fixed correction, lingual clasps, and traction hooks.

[0066] 2) Restoration Angle: The preoperative digital tooth arrangement results are used to determine the position of the anterior dentition for restoration. This allows for the design of the final restoration. The provisional restorations produced in this embodiment are already designed to meet the requirements of the final restoration, ensuring a high degree of consistency between orthodontic goals and restoration requirements.

[0067] 3) Achieving the target position based on root-bone relationships: After removing the original restoration, the temporary restoration created using this method takes into account the original root position, allowing the teeth to be adjusted to a reasonable position during the orthodontic process, restoring a healthy root-bone relationship. We call this process restorative decompensation. Only after this is completed can orthodontic adjustments be made to the correct tooth position, achieving the optimal restoration.

[0068] 4) From an aesthetic point of view: temporary restorations designed with the end in mind can meet the aesthetic needs of adult patients for anterior teeth to the greatest extent, allowing them to achieve both beauty and correction.

[0069] In this embodiment, there is a further improvement for step S6. During the process of assembling the temporary tooth restoration, a guide plate 3 can be used to achieve precise assembly.

[0070] Specifically, when assembling a temporary dental restoration, it is difficult to ensure that the veneer is precisely positioned in the designed position due to direct operation with bare hands. This will cause the accessories on the veneer to shift slightly, making it impossible to accurately assemble the temporary dental restoration with accessories according to the original restoration tooth arrangement.

[0071] See also Figure 3 and Figure 4 In this embodiment, when assembling the accessories, the veneer with adhesive is first placed on the original tooth surface, and then the guide plate 3 is accurately positioned to achieve a locking effect. After the adhesive is completely cured, the dental restoration 4 is finally accurately assembled on the native tooth, and its shape completely matches the original restoration tooth arrangement shape.

[0072] It should be noted that temporary tooth restorations exist in the patient's mouth for a long time, generally 2-3 years. During such a long period of time, it is inevitable that the original teeth may develop caries.

[0073] In order to prevent the occurrence of caries, in this embodiment, an anti-caries coating is provided on the bonding surface of the temporary dental restoration. In this way, the patient can be guaranteed not to develop caries during the period of "the temporary dental restoration exists in the patient's mouth for 2-3 years".

[0074] It should be noted that the concept of "integrating accessories into a temporary dental restoration" in this embodiment can also be applied to other components attached to teeth. For example, in another embodiment, during orthodontic procedures, brackets, lingual clasps, and traction hooks need to be fixed to the teeth (as will be understood by those skilled in the art). In this case, the brackets, lingual clasps, and traction hooks can also be integrated into the temporary dental restoration based on the concept of the temporary dental restoration in this embodiment. This can also significantly reduce the hassle of orthodontic procedures for patients undergoing dental restorations, thereby achieving excellent results.

[0075] For the sake of convenience, accessories, brackets, lingual clips, traction hooks, etc. can be collectively referred to as "tooth accessory components".

[0076] The following is a specific example of a temporary tooth restoration and its construction method using the present invention:

[0077] (1) See Figure 5The orthodontic patient had multiple poorly made restorations and needed to have transitional restorations remade.

[0078] (2) See Figure 6 , oral scans record the original shape of teeth and design orthodontic plans.

[0079] (3) See Figure 7 , tooth preparation guided by the guide.

[0080] (4) See Figure 8 According to the original shape of the tooth, a temporary restoration with accessories is digitally designed and cut.

[0081] (5) See Figure 9 , under the accessory template, complete the bonding of the temporary restoration with accessories.

[0082] (6) See Figure 10 , bonding is completed.

[0083] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
