Description

Temporary dental restoration and method for constructing the same TECHNICAL FIELD

[0001] The present application relates to a dental restoration technique, in particular to a temporary dental restoration and a method for constructing the same. BACKGROUND

[0002] Orthodontic treatment is a modern orthodontic method that uses a three-dimensionally designed transparent appliance (invisible aligner) to gradually adjust the position of teeth to achieve alignment and improve occlusion.

[0003] As understood by those skilled in the art, during orthodontic treatment, an appliance (commonly referred to as an "invisible aligner", also known as an "invisible dental brace") is required, which needs to use a small device called an "attachment" during use.

[0004] The "attachment" refers to a small device attached to the surface of a tooth, usually made of light-cured composite resin similar in color to the tooth. The attachment has two main functions: one is to assist tooth movement, and the other is to assist appliance retention. Overall, it is used to enhance the control force and accuracy of the appliance on the teeth.

[0005] Commonly used attachments include rectangular attachments, wedge-shaped attachments, optimized attachments, and the like.

[0006] For normal people, during orthodontic treatment, acid etching is first performed on the surface of the teeth, a special orthodontic adhesive is applied to the surface of the teeth, and the attachment is placed on the adhesive with the assistance of an attachment template, adjusted according to the designed position and direction.

[0007] However, at present, the age composition of orthodontic patients is characterized by an increasing proportion of adult patients year by year, and these patients often have complex oral health conditions with different numbers of restorations in the mouth. For these patients who have undergone crown restoration (including all-ceramic crown, porcelain crown, metal crown) or veneer restoration (i.e., the patient's teeth have dental restorations installed), it is very difficult to perform orthodontic treatment, as follows:

[0008] 1) The surface of a conventional dental restoration is ceramic or metal, and the surface of the dental restoration cannot be acid etched in the conventional manner. In such a case, if the attachment is bonded to the surface of the ceramic or metal dental restoration, effective bonding cannot be achieved, and the attachment is prone to falling off;

[0009] 2) Hydrofluoric acid (strong acid preparation) can currently be used to acid etch the surface of the dental restoration, but this process can potentially harm the patient.

[0010] 3) If the method of "directly bonding the attachment on the dental restoration" is not adopted, the original dental restoration can also be removed, and after the technician completes the transitional resin restoration, a new orthodontic plan is made according to the oral condition of the patient after the transitional restoration, and the orthodontic operation is finally completed. However, such a method is very inconvenient for both doctors and patients. Patients need multiple visits, including orthodontic plan development, removal of the original restoration, installation of a temporary dental restoration, and development of a new orthodontic plan. Doctors need to complete the restoration process, restoration bonding, and attachment bonding in several steps. These operations and rechecks greatly increase the patient's visit time and the doctor's work time.

[0011] 4) From the perspective of post-orthodontic restoration, the main issue is the precision of the restoration. There is a large communication barrier between orthodontists (doctors who specialize in orthodontic surgery operations) and restorative dentists (doctors who specialize in dental restoration). Specifically, because the design requirements of the restorative dentist cannot be determined in advance, it is difficult to achieve precise postoperative restoration space. As a result, the orthodontist needs to repeatedly communicate with the restorative dentist, and during this communication process, the restorative dentist's estimate may also be biased, leading to inconsistencies between the orthodontic reserved restoration space and the restoration required space, repeated coordination, increased treatment time, or the need for the restorative dentist to compromise.

[0012] 5) From the perspective of the target position of the orthodontic tooth movement, the existing technology cannot obtain an orthodontic target position based on healthy root bone relationships. Many patients have uneven tooth alignment and protrusion before restoration, which affects the appearance of the tooth alignment. During previous anterior tooth restoration, the original tooth alignment appearance problem has often been concealed and compensated for by tooth preparation and restoration modification. If the restoration is not re-made according to the original position, it is not possible to align these restored teeth according to the reasonable tooth root position, resulting in the inability to achieve a healthy root bone relationship and the inability to achieve the best treatment effect.

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

[0014] In summary, the current problem is:

[0015] For patients with dental restorations in their mouths, the orthodontic process will encounter many difficulties as described above, both for doctors and patients, and will incur significant human and social costs. SUMMARY

[0016] One of the purposes of the present application is to provide a temporary dental restoration that replaces the original dental restoration in the patient's mouth, and then the patient receives subsequent orthodontic operations, thereby avoiding complicated operation processes.

[0017] The second object of the present application is to provide a method for constructing a temporary dental restoration.

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

[0036] The present application will be further described below with specific examples:

[0037] Referring to Fig. 1, the present embodiment provides a temporary dental restoration, and the innovation of the temporary dental restoration is that an accessory 2 for orthodontic operation is integrally combined on the temporary dental restoration 1, specifically, on the outer surface of the temporary dental restoration 1.

[0038] The temporary dental restoration is used to be assembled and bonded on the original natural teeth of a patient to replace the original dental restoration, and then the patient receives subsequent orthodontic operation. In this way, for the dental restoration patient, the temporary dental restoration 1 of the present embodiment is used to replace the original dental restoration, and then the orthodontic plan is implemented on the patient, which will avoid many difficult conditions in the process of orthodontic operation. The orthodontic plan is no longer a troublesome thing. Both the doctor and the patient can greatly reduce the cost of human 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 accessory 2 are integrally made of a resin material.

[0040] In order to achieve the above-mentioned temporary tooth restoration, the embodiment further provides a temporary tooth restoration construction method, which integrally constructs a temporary tooth restoration combined with an accessory, and provides stable and reliable accessory support for orthodontic operation.

[0041] It should be noted that the patient group targeted by the temporary tooth restoration construction method of the embodiment is a patient who has undergone crown restoration or veneer restoration (that is, the patient has a tooth restoration in the oral cavity). In order to facilitate description, such a patient is defined as a "tooth restoration patient".

[0042] Referring to FIG. 2, the temporary tooth restoration construction method mainly includes the following steps S1 to S7.

[0043] S1, for a tooth restoration patient, using an existing oral scanning device to scan the tooth arrangement form in the patient's oral cavity, and obtaining and recording the 3D scanning data of the tooth arrangement form.

[0044] For convenience of description, the tooth arrangement form at this time is defined as a "restoration tooth arrangement form".

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

[0046] It should be noted that in the embodiment, the 3D scanning data obtained by scanning is saved in an STL file format. In the process of designing and manufacturing the restoration and its accessory, the STL format file facilitates subsequent digital design, modification and manufacturing steps. Such a format file can be edited by CAD software, or directly used for 3D printing or milling manufacturing process.

[0047] S2, input the restoration tooth arrangement form 3D scanning data obtained in step S1 into a computer, use professional 3D modeling software, and based on the restoration tooth arrangement form, design an orthodontic operation scheme for the patient, determine the accessory to be used, and determine the three-dimensional position and shape and size of the accessory on the teeth; then in the 3D modeling software, the determined accessory is integrally combined on the restoration tooth arrangement form, thereby constructing a tooth arrangement form containing the accessory based on the restoration tooth arrangement form, and obtaining the corresponding 3D data; the 3D data of the tooth arrangement form containing the accessory is saved in the form of an STL format file.

[0048] In step S2, the integrated attachment is designed based on the restorative tooth arrangement according to the pre-established orthodontic operation scheme, so as to obtain the 3D data of the tooth arrangement with the attachment.

[0049] S3, the original porcelain crown or the tooth restoration of the patient is removed, and then the oral scanning device is used again to scan the original tooth arrangement after the original tooth restoration is removed, so as to obtain and record the 3D scanning data of the tooth arrangement after the original tooth restoration is removed.

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

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

[0052] It should be noted that the original tooth body can be refined before the original tooth arrangement is scanned.

[0053] S4, the 3D data of the tooth arrangement with the attachment obtained in step S2 and the original tooth arrangement obtained in step S3 are input into the computer, and then the professional 3D modeling software is used to design the temporary tooth restoration according to the tooth arrangement with the attachment and the original tooth arrangement, and then the existing technical equipment is used to obtain 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 the basic configuration of the temporary tooth restoration is consistent with the original tooth restoration in the oral cavity of the tooth restoration patient, but compared with the original tooth restoration, the temporary tooth restoration is combined with an integrated attachment.

[0055] S5, for the temporary tooth restoration obtained in step S4, some post-processing procedures of the temporary tooth restoration are performed, such as:

[0056] 1) the temporary tooth restoration is placed in the patient's mouth for trial fitting,

[0057] 2) the temporary tooth restoration is subjected to acid etching treatment,

[0058] 3) the temporary tooth restoration is subjected to moisture-proof treatment.

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

[0060] S6, the temporary tooth restoration combined with the attachment is assembled on the original tooth of the patient by bonding to replace the original tooth restoration, and then the patient is scanned again to obtain new 3D scanning data and save it as an stl file. The new oral 3D scanning data is matched with the orthodontic operation scheme formulated in step S2, so as to complete the design and production of the appliance.

[0061] S7, re-produce the final restoration for the tooth restoration patient, after completing the orthodontic treatment, remove the temporary tooth restoration in the patient's mouth, and replace the temporary tooth restoration in the patient's mouth with the final restoration.

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

[0063] The temporary tooth restoration and its construction method of the embodiment are used to implement the orthodontic plan for the tooth restoration patient, which can avoid many difficult conditions in the process of implementing the orthodontic treatment, and the orthodontic plan is no longer a troublesome thing. Both for doctors and patients, the human and social costs can be greatly reduced, thereby achieving good results.

[0064] Specifically,

[0065] 1) Let the attachment and the temporary restoration be well connected to solve the retention problem of the attachment. Including all types of attachments that need to be connected: invisible correction resin attachment, fixed correction bracket, lingual buckle, traction hook.

[0066] 2) Repair angle: obtain the position relationship of the pre-restoration dentition through the results of preoperative digital tooth arrangement. Realize the design of the final restoration. The temporary restoration produced in the embodiment has been completed according to the requirements of the final restoration, ensuring the high consistency of the orthodontic target and the repair requirements.

[0067] 3) Obtain the target position based on the root bone relationship: after the original restoration is removed, the temporary restoration produced by the method in the embodiment has considered the original tooth root position, allowing the teeth to be adjusted to a reasonable position during the orthodontic process, and restoring the healthy root bone relationship. We call this process repair decompensation. After completing the repair decompensation, the tooth position can be adjusted by orthodontic treatment, thereby achieving the best repair.

[0068] 4) From the aesthetic point of view: the temporary restoration with the end in mind can best meet the aesthetic needs of adult patients for front teeth, allowing both beauty and correction.

[0069] In the embodiment, further improvements are made to step S6. During the assembly of the temporary tooth restoration, a guide plate 3 can be used to achieve precise assembly.

[0070] Specifically, when assembling the temporary tooth restoration, it is difficult to ensure that the veneer is accurately positioned at the designed position due to direct operation with bare hands, which can cause slight displacement of the attachments on the veneer, resulting in that the temporary tooth restoration with attachments cannot be accurately assembled according to the original tooth restoration arrangement form.

[0071] Referring to FIGS. 3 and 4, in the embodiment, when assembling the attachments, the veneer with the adhesive is first placed on the original tooth surface, then the guide plate 3 is accurately positioned to achieve the locking effect, the adhesive is completely cured, and finally the tooth restoration 4 is accurately assembled on the original tooth, which is completely matched with the original tooth restoration arrangement form.

[0072] It should be noted that the temporary tooth restoration exists in the patient's oral cavity for a long time, generally for 2-3 years, and during such a long period of time, the original tooth may inevitably have caries;

[0073] In order to prevent the occurrence of caries, in the embodiment, the bonding surface of the temporary tooth restoration is provided with a caries-preventing coating, so that during the period of "2-3 years of existence of the temporary tooth restoration in the patient's oral cavity", the patient can be ensured not to have caries.

[0074] It should be noted that the concept of "integrally combining the attachments on the temporary tooth restoration" in the embodiment can also be used for other components combined on the teeth. For example, in another embodiment, when orthodontic operation is needed, brackets, lingual buttons, and traction hooks (understood by those skilled in the art) need to be fixedly arranged on the teeth, then the brackets, lingual buttons, and traction hooks can be integrally combined on the temporary tooth restoration based on the concept of the temporary tooth restoration in the embodiment. In this way, when the dental restoration patient receives orthodontic operation, many troubles can be reduced, thereby achieving good effects.

[0075] For convenience of description, the attachments, brackets, lingual buttons, traction hooks, etc. can be collectively referred to as "dental attachment combination".

[0076] A specific case of using the temporary tooth restoration and the construction method thereof according to the present application is given below:

[0077] (1) Referring to FIG. 5, the orthodontic patient has many bad restorations, and needs to re-produce a transitional restoration.

[0078] (2) Referring to FIG. 6, the original shape of the teeth is recorded by oral scanning, and an orthodontic plan is designed.

[0079] (3) Referring to FIG. 7, tooth preparation under the guidance of the guide plate.

[0080] (4) Referring to Fig. 8, the temporary restoration with attachment is designed and cut according to the original shape of the tooth.

[0081] (5) Referring to Fig. 9, the temporary restoration with attachment is bonded under the attachment template.

[0082] (6) Referring to Fig. 10, the bonding is completed.

[0083] The above merely describes the preferred embodiments of the present application, but not for limiting the protection scope of the present application, thus, any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
