[0001] Cross-reference

[0002] This application claims priority to Chinese Patent Application No. 202410495675.1, filed on April 24, 2024, entitled “Data Processing Method, Apparatus, Device and Medium for Dental Implants”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of three-dimensional technology, and in particular to a data processing method, apparatus, device and medium for dental implants. Background Technology

[0004] Traditional dental implant procedures are time-consuming, require multiple sessions, and have a poor experience. Related technologies can utilize 3D scanning data to design implant guides, which are then used to assist in implant surgery. 3D scanning data can also be used to design crowns and abutments, allowing teeth to be worn immediately after the implant surgery.

[0005] However, the above methods have low accuracy because deviations may occur during the implantation surgery, resulting in the crown and abutment not matching the actual situation and failing to be placed. Furthermore, the crown and abutment restored immediately are temporary teeth, and it is necessary to wait for the wound to heal before another intraoral scan is needed to design the final crown and abutment. The time cost of wearing the teeth is high and the efficiency is low. Summary of the Invention

[0006] To solve the above-mentioned technical problems, or at least partially solve them, this disclosure provides a data processing method, apparatus, device, and medium for dental implants.

[0007] This disclosure provides a data processing method for dental implants, the method comprising:

[0008] In response to the scanning operation of the target tooth position of the drill bit, acquire drill bit scanning data;

[0009] Based on the drill bit scanning data, the crown and abutment of the target tooth position are designed, and the tooth is fitted to the target tooth position based on the crown and the abutment.

[0010] This disclosure also provides a data processing device for dental implants, the device comprising:

[0011] The acquisition module is configured to acquire drill bit scan data in response to a scanning operation on the target tooth position of the drill bit.

[0012] The design module is configured to design the crown and abutment of the target tooth position based on the drill bit scanning data, so as to perform the tooth-wearing operation on the target tooth position based on the crown and the abutment.

[0013] This disclosure also provides an electronic device, the electronic device comprising: a processor; a memory configured to store executable instructions of the processor; the processor being configured to read the executable instructions from the memory and execute the instructions to implement the dental implant data processing method provided in this disclosure.

[0014] This disclosure also provides a computer-readable storage medium storing a computer program configured to perform the dental implant data processing method provided in this disclosure.

[0015] Compared with the prior art, the technical solution provided in this disclosure has the following advantages: The data processing scheme for dental implants provided in this disclosure acquires drill bit scanning data in response to the scanning operation of the target tooth position where the drill bit is inserted; the crown and abutment of the target tooth position are designed based on the drill bit scanning data, and the tooth is then placed on the target tooth position based on the crown and abutment. Using the above technical solution, after drilling the tooth with a drill bit, a scanning operation is performed on the entire tooth into which the drill bit is inserted to acquire drill bit scanning data. The crown and abutment designed based on this drill bit scanning data are the final crown and abutment, and the tooth can be placed directly. This not only avoids errors caused by deviations in the implant surgery process and improves the accuracy of crown and abutment design, but also saves the step of waiting for wound healing and scanning again, reducing the time cost of implant surgery and improving the efficiency of tooth placement.

[0025] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0026] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0027] Traditional dental implant surgery involves first extracting the tooth, then waiting for the extraction site to heal before performing implant surgery (drilling) and inserting the implant. A healing cap is then installed on the implant. After new bone formation and implant stabilization (approximately 2-3 months), a scanning probe is installed on the implant to scan the 3D data of the implant site. This allows for the design and fabrication of the crown, ultimately resulting in the patient receiving the implant. Traditional implant surgery lacks specialized computer-aided design software and solutions to design and fabricate the abutment and crown immediately after extraction and drilling. It requires multiple visits, including extraction, drilling, implant placement, and the installation of the healing cap, potentially leading to a longer treatment time and a poor patient experience. The process involves multiple visits from surgery to implant placement, longer treatment times, and a less than ideal patient experience.

[0028] In contrast to traditional procedures, related technologies can provide a surgical procedure using a surgical guide for implant dentistry. For example, Figure 1 is a schematic diagram of the implantation procedure of the related technology. The specific implantation procedure may include: designing an implantation guide using CT data and intraoral scan data taken during the patient's visit before surgery, and manufacturing the implantation guide using the designed digital guide data for later use in the surgery. During the surgery, the guide is installed in the patient's mouth. The guide can assist in the drilling process, making the implant placement more precise and in line with expectations. Furthermore, when designing the guide before surgery, design software is used to simulate the implant position and design the crown and abutment, so that the tooth can be worn immediately after the implant surgery. However, because the patient's bone density cannot be accurately predicted on CT data, the implant is unstable after the surgical guide procedure and cannot be immediately restored, as wearing a tooth at this time would affect the implant healing process. If there are deviations during the surgery, such as drill deviation at a certain step, the implant position simulated using the guide may not match the actual position, and the crown may not be able to be placed properly. Furthermore, this crown is only temporary, remaining in the patient's mouth for no more than three months. Final restoration requires installing a scanning rod on the implant to scan the three-dimensional data inside the implant, then designing and fabricating the crown before finally placing it on the patient. In summary, dental implant crowns and abutments suffer from low accuracy during the design phase, and the timing of the design leads to high time costs and low efficiency in placing the implant.

[0029] To address the aforementioned issues, this disclosure provides a data processing method for dental implants, which will be described below with reference to specific embodiments.

[0030] Figure 2 is a flowchart illustrating a data processing method for dental implants according to an embodiment of this disclosure. This method can be executed by a data processing device for dental implants, which can be implemented using software and / or hardware and is generally integrated into an electronic device. As shown in Figure 2, the method includes:

[0031] Step 101: In response to the scanning operation of the target tooth position of the drill bit, acquire drill bit scanning data.

[0032] The dental implant processing method of this disclosure can be performed by a scanning device, which may be an intraoral scanner, including a data acquisition device for performing oral scans on the user to obtain all oral scan data (including scans of teeth and gingiva), and a data processing device (including a computer, mobile phone, tablet computer, etc.) connected to the data acquisition device via wired or wireless connection. The data acquisition device may include an intraoral scanner or an extraoral scanner, or it may be implemented by using a drill (i.e., an implant handpiece) with a camera, or it may include an intraoral scanner and a tracker, or it may include an intraoral scanner and a facial scanner. The scanning device of this disclosure can also integrate design tools for designing implant guides, crowns, abutments, etc., or it may send various design tasks to a cloud platform via communication to achieve the design of implant guides, crowns, abutments, etc.

[0033] The target tooth location can be the tooth that requires dental implant surgery. There can be one or more target teeth, and the tooth at this location needs to be extracted before the implant is placed. A dental implant is a method of restoring missing teeth by using a substructure implanted into the bone tissue to support and retain the superstructure. A dental implant includes a substructure (implant) and a superstructure (crown). The implant and crown are connected by an abutment. The implant, or artificial tooth root, is implanted into the alveolar bone and is responsible for supporting the superstructure (crown). The crown is placed on the abutment to perform the chewing function and aesthetics of the tooth. A drill bit is used to drill into the target tooth location in preparation for the subsequent implant placement. Drill bit scan data is obtained by scanning the area of ​​the target tooth location where the drill bit has been inserted, using a scanning device after drilling to the preset position. The scanning process requires scanning the entire area of ​​the drill bit.

[0034] Specifically, the scanning device can scan the patient's mouth to obtain three-dimensional oral data before dental implant surgery. It can also acquire cone-beam computed tomography (CBCT) data. Using design tools, a suitable implant guide can be designed based on the three-dimensional oral data and CBCT data. The implant guide is then used to perform the tooth extraction drilling surgery on the patient. After the drill bit has drilled into the target tooth position, the scanning device can perform a second scan on the target tooth position to obtain drill bit scan data.

[0035] In some embodiments, acquiring drill bit scanning data in response to a scanning operation on the target tooth position of the drill bit may include: setting the scanning mode to a metal scanning mode in response to a scanning trigger operation or the detection that the drill bit has entered the target tooth position; performing a scanning operation on the target tooth position of the drill bit in the metal scanning mode; and determining the scanning data obtained from the scanning operation as drill bit scanning data.

[0036] The scan trigger operation can be a user's gesture control operation (such as clicking, long pressing, double-clicking, etc.), voice control operation, or facial expression control operation on the scanning controls in the scanning device, etc., and this disclosure embodiment does not limit this. The metal scanning mode can be a scanning mode in the scanning device used for scanning metal, which can prevent data errors caused by metal reflection. When the scanning device receives a scan trigger operation, it can set the scanning mode to metal scanning mode and control the scanning operation on the target tooth position of the drill bit in metal scanning mode, and determine the obtained scanning data as the drill bit scanning data.

[0037] In some embodiments, the drill bit is detachably mounted on the drilling machine (i.e., implant handpiece). To avoid collisions with drilling auxiliary tools such as the drilling machine during the oral scanning and drilling process, and to avoid the drilling auxiliary tools such as the drilling machine obstructing the scanning line of sight, after drilling is completed, the drilling machine is stopped, the drill bit is removed from the drilling machine, placed back on the tooth position, and then the oral scanning machine is used to scan the tooth position and the drill bit to obtain the drill bit scanning data.

[0038] In some embodiments, the implantation guide can be made of a transparent material, and the influence of the transparent implantation guide on the scan data can be ignored when the drill bit scan data is obtained.

[0039] In some embodiments, the drill bit and the implantation guide are detachable, and the implantation guide can be removed before scanning when the drill bit scanning data is obtained.

[0040] For example, Figure 3 is a schematic diagram of a target tooth position of a drill bit provided in an embodiment of this disclosure. As shown in Figure 3, the figure shows a schematic diagram of the drill bit 301 drilling into the target tooth position 302. The target tooth position 302 is only an example. There can be one or more target tooth positions. The drill bit 301 can drill a hole in the target tooth position 302 according to the position, depth, angle, direction and other data of the implant of the implant guide plate. After stopping, the scanning device can perform an overall scan of the target tooth position 302 into which the drill bit 301 has entered to obtain the drill bit scanning data.

[0041] Step 102: Design the crown and abutment of the target tooth position based on the drill bit scanning data, and perform the tooth placement operation on the target tooth position based on the crown and abutment.

[0042] The crown is the part of the dental implant structure that is mounted on the abutment to achieve the tooth's chewing function and aesthetic appearance. The abutment is a connecting device that connects the implant and the crown.

[0043] Specifically, the scanning device can input drill bit scanning data into the design tool. Through the visual simulation interface in the design tool, the position of the implant can be simulated using the drill bit position in the drill bit scanning data. Combining the drill bit angle, drill bit position, drill bit thickness, drill bit shape, and the positional relationship between the drill bit and the tooth jaw in the drill bit scanning data, the crown and abutment of the target tooth position are designed. After the crown and abutment are made, they are placed into the user's target tooth position to complete the dental implantation operation.

[0044] In some embodiments, designing the crown and abutment of the target tooth position based on drill bit scanning data may include: extracting the drill bit angle and drill bit position from the drill bit scanning data; and designing the crown and abutment of the target tooth position using a design tool based on the drill bit angle and drill bit position.

[0045] The drill bit angle can be the angle between the drill bit and the reference plane when the drill bit is inserted into the target tooth position, and the drill bit position can be the specific location of the drill bit when it is inserted into the target tooth position. In addition to inputting all the drill bit scanning data into the design tool to obtain the crown and abutment, the scanning device can also extract the drill bit angle and position from the drill bit scanning data, input the drill bit angle and position into the design tool, and use the visual simulation interface of the design tool to design the crown and abutment of the target tooth position.

[0046] In this solution, there is no need to wait for the patient's wound to heal before scanning the patient's mouth and then designing and fabricating the abutment and crown. Instead, the abutment and crown can be designed and fabricated immediately after drilling, allowing the patient to wear the teeth ahead of time and end the treatment. This not only improves the accuracy of crown and abutment design but also saves time, increases the efficiency of wearing the teeth, and thus enhances the user experience.

[0047] The data processing scheme for dental implants provided in this disclosure, in response to a scanning operation of the target tooth position where the drill bit is inserted, acquires drill bit scanning data; based on the drill bit scanning data, designs the crown and abutment for the target tooth position, and performs the implantation operation based on the crown and abutment. Using the above technical solution, after drilling the tooth with the drill bit, a scanning operation is performed on the entire tooth into which the drill bit is inserted to acquire drill bit scanning data. The crown and abutment designed based on this drill bit scanning data are the final crown and abutment, allowing for direct implantation. This not only avoids errors caused by deviations in the implantation procedure and improves the accuracy of crown and abutment design, but also saves the step of waiting for wound healing and re-scanning, reducing the time cost of implantation surgery and improving implantation efficiency.

[0048] In some embodiments, the data processing method for dental implants may further include: acquiring first oral cavity three-dimensional data and determining target tooth position data in the first oral cavity three-dimensional data; deleting the target tooth position data in the first oral cavity three-dimensional data to obtain second oral cavity three-dimensional data, and stitching the second oral cavity three-dimensional data with drill bit scanning data to obtain third oral cavity three-dimensional data; and designing the crown and abutment of the target tooth position based on the third oral cavity three-dimensional data.

[0049] The oral cavity 3D data can be all scan data obtained by scanning the user's mouth using a scanning device, including scans of the teeth and gums, specifically including the user's intraoral data, occlusal data, etc. The first oral cavity 3D data can be obtained by scanning the user's mouth before the dental implant surgery. The target tooth position data can be a portion of the oral cavity 3D data corresponding to the target tooth position. The second oral cavity 3D data can be obtained by deleting the target tooth position data from the first oral cavity 3D data. The third oral cavity 3D data can be obtained by stitching the second oral cavity 3D data with the aforementioned drill bit scan data; that is, by deleting the target tooth position data from the first oral cavity 3D data and replacing it with drill bit scan data, which is obtained by scanning the target tooth position after the drill bit has reached a preset position.

[0050] It should be noted that the deletion operation of the target tooth position data from the first oral cavity three-dimensional data in this application embodiment has multiple implementation schemes, including but not limited to: one implementation scheme is to separate the target tooth position data from the first oral cavity three-dimensional data, and only retain the first oral cavity three-dimensional data after the target tooth position data is separated in the display interface. In this implementation scheme, the deletion operation is a selective retention of the display result, rather than completely deleting the target tooth position data, that is, only deleting the target tooth position data from the display interface; another implementation scheme is to directly and completely delete the target tooth position data from the source data; yet another implementation scheme is to separate the target tooth position data from the first oral cavity three-dimensional data and increase the transparency of the separated target tooth position data, such as displaying it with semi-transparency, so as to achieve the effect of highlighting the remaining first oral cavity three-dimensional data in the display interface; yet another implementation scheme is to delete the target tooth position data from the intermediate product of the reconstruction model or the reconstructed model, so that the display interface does not display the target tooth position data.

[0051] Optionally, determining the target tooth position data in the first oral cavity three-dimensional data may include: performing tooth position identification on the first oral cavity three-dimensional data to determine the parameters of the target tooth position to be processed; extracting the partial data corresponding to the parameters of the first oral cavity three-dimensional data and the target tooth position, and determining the partial data as the target tooth position data.

[0052] The parameters for the target tooth position can be uniquely characterized, for example, they can be represented numerically. After acquiring the first three-dimensional oral cavity data, the scanning device can determine the parameters of the target tooth position in the first three-dimensional oral cavity data in response to the user's selection, or identify the target tooth position requiring dental implant surgery by performing tooth position recognition on the three-dimensional model in the first three-dimensional oral cavity data, and obtain the parameters of the target tooth position; then, it can extract the portion of data in the first three-dimensional oral cavity data corresponding to the parameters of the target tooth position, and determine this portion of data as the target tooth position data. Afterwards, the scanning device can delete the target tooth position data from the first three-dimensional oral cavity data to obtain the second three-dimensional oral cavity data, and stitch the second three-dimensional oral cavity data with the drill bit scan data from the supplementary scan to obtain the third three-dimensional oral cavity data; the third three-dimensional oral cavity data is then input into the design tool to design the crown and abutment of the target tooth position.

[0053] Optionally, the design tool described above can also operate independently of the scanning device. The scanning device can send the drill bit scanning data or the third oral cavity 3D data to the design tool, enabling the design of the crown and abutment for the target tooth position. Specifically, the design process involves importing the drill bit scanning data or third oral cavity 3D data into the design tool. The design tool can display the drill bit scanning data or third oral cavity 3D data. Designers can utilize the visual simulation interface and function buttons provided by the design tool, combined with the drill bit angle, position, thickness, shape, and positional relationship between the drill bit and the jaw from the drill bit scanning data or third oral cavity 3D data, to design the crown and abutment for the target tooth position.

[0054] In the above scheme, the scanning device can not only design crowns and abutments based solely on drill bit scanning data, but also obtain the final oral cavity three-dimensional data after drilling by replacing the target tooth position data in the original oral cavity three-dimensional data with drill bit scanning data. Based on this complete final oral cavity three-dimensional data, crowns and abutments can be designed more conveniently and quickly, thereby improving the efficiency of subsequent denture fitting.

[0055] In some embodiments, designing the crown and abutment of the target tooth position using a design tool based on the drill bit angle and the drill bit position may include: acquiring third-dimensional oral cavity data, and determining the position information of the implant at the target tooth position and the size and margin information of the crown and abutment at the target tooth position based on the third-dimensional oral cavity data; determining the orientation of the crown and abutment at the target tooth position based on the drill bit angle and the drill bit position; and designing the crown and abutment at the target tooth position using a design tool based on the position information of the implant at the target tooth position and the size, orientation, and margin information of the crown and abutment at the target tooth position.

[0056] The first 3D oral data can be obtained by scanning the patient's mouth before the dental implant surgery. The third 3D oral data can be obtained by deleting the target tooth position data from the first 3D oral data and replacing it with drill bit scan data.

[0057] After acquiring the three-dimensional data of the third oral cavity, the scanning device can simulate the position information of the implant at the target tooth location based on the drill bit angle, position, thickness, shape, and positional relationship between the drill bit and the jawbone. It can also identify the gingival margin information of the target tooth location based on the three-dimensional data, and determine the margin information of the crown and abutment. Furthermore, it can identify the reserved space between the target tooth location and its adjacent teeth based on the three-dimensional data, and determine the dimensions of the crown and abutment. Finally, it can calculate the orientation of the crown and abutment based on the normal phase principle using the drill bit angle and position. The position information of the implant at the target tooth location, along with the dimensions, orientation, and margin information of the crown and abutment, are then input into a design tool to design the crown and abutment for the target tooth location.

[0058] In other embodiments, designing the crown and abutment of the target tooth position using a design tool based on the drill bit angle and the drill bit position may include: acquiring first three-dimensional oral cavity data and determining first drilling information based on the first three-dimensional oral cavity data; determining initial design information of the crown and abutment of the target tooth position using the design tool based on the first three-dimensional oral cavity data and the first drilling information; determining second drilling information based on the drill bit angle and the drill bit position; comparing the first drilling information and the second drilling information to determine the offset information of the drill bit, and correcting the initial design information based on the offset information to obtain target design information of the crown and abutment of the target tooth position.

[0059] The first three-dimensional oral data can be obtained by scanning the patient's mouth before the dental implant surgery. Specifically, the scanning device can acquire the first three-dimensional oral data and determine the first drilling information based on it. This first drilling information can be drilling-related information designed using a design tool based on the first three-dimensional oral data. The first three-dimensional oral data and the first drilling information are input into the design tool to obtain the initial design information for the crown and abutment of the target tooth position. The initial design information can include all design information for the crown and abutment of the target tooth position before the dental implant surgery, such as dimensions and size. The second drilling information is determined by reverse calculation based on the drill bit angle and position. This second drilling information can be obtained by reverse calculation after the actual drilling. The drilling information is obtained, and then the designed first drilling information and the actual second drilling information are compared to determine the offset information of the actual operation relative to the designed drill bit. This offset information can include offset angle and offset displacement. The offset angle and offset displacement are input into the design tool, and the design tool is used to correct the initial design information of the crown and abutment of the target tooth position according to the offset angle and offset position to obtain the final target design information of the crown and abutment of the target tooth position. This target design information can be all the design information of the crown and abutment of the target tooth position after drilling. Based on this target design information, the crown and abutment of the target tooth position can be fabricated.

[0060] In the above scheme, when designing the crown and abutment of the tooth, the crown and abutment can be designed directly based on the relevant data of the drill bit's drilling position, or the initial crown and abutment can be designed first based on the designed drilling information, and the offset information determined by comparing the drilling information after the drill bit's drilling position with the designed drilling information can be used to correct the collapse of the initial crown and abutment to achieve the design of the crown and abutment. The two methods can be selected according to the actual situation to improve the design flexibility.

[0061] In some embodiments, the data processing method for dental implants may further include: verifying the crown and abutment of the target tooth position; and when the verification result is passed, sending the crown and abutment of the target tooth position to the manufacturing end for manufacturing.

[0062] Verification can be understood as a design-level applicability verification of the crown and abutment after design. Optionally, verification includes usability verification, size verification, and / or occlusal verification. Usability verification includes verifying the angle of the crown and / or abutment, that is, verifying whether the angle of the crown and / or abutment is normal or whether it is a case of overbite, etc. Size verification includes verifying the size of the crown and / or abutment, that is, verifying whether the size of the crown and / or abutment is suitable for the alveolar bone of the target tooth position. Specifically, it can be verified using an error elimination mechanism. Occlusal verification is used to verify whether wearing the crown and abutment affects the occlusal function of the target tooth position. Specifically, it can be verified by simulating the user's occlusal function using data of mandibular movement trajectory to verify whether the crown and / or abutment affect the occlusion of the target tooth position.

[0063] After the scanning device designs the crown and abutment of the target tooth position based on the drill bit scanning data in step 102 above, it can verify the crown and abutment of the target tooth position. Specifically, it can perform usability verification, size verification and / or occlusion verification. When all verification results are passed, the crown and abutment of the target tooth position can be sent to the manufacturing end for manufacturing. When a certain verification result is failed, a prompt message can be sent to the user so that the user can redesign the crown and abutment of the target tooth position using the design tool until all verification results are passed.

[0064] In the above scheme, by adding verification operations such as usability verification, size verification, and occlusion verification after the design of the crown and abutment, the design accuracy of the crown and abutment can be further improved, avoiding subsequent failure of tooth wearing due to design errors.

[0065] The following specific examples will further illustrate the dental implant processing method of this disclosure. For example, Figure 4 is a schematic diagram of an implantation process provided by an embodiment of this disclosure. As shown in Figure 4, the complete process of dental implant surgery is illustrated. The scanning and design steps in the figure can both be performed by the scanning device, or the scanning step can be performed by the scanning device and the design step can be performed by an external design tool. The specific process may include: preoperative scanning (scanning the user's complete intraoral preoperative data), that is, obtaining the first oral cavity three-dimensional data; sending the scan data (that is, the first oral cavity three-dimensional data) to the design tool, the design tool can combine the first oral cavity three-dimensional data and CBCT imaging data to design the implant guide and implantation plan, and return the design data to the surgeon; the surgeon performs tooth extraction and drilling surgery, and after the drill bit reaches the end, the jaw is scanned again based on the preoperative scan (the area where the drill bit will be placed must be scanned) to obtain the third oral cavity three-dimensional data; sending the scan data (the third oral cavity three-dimensional data) to the design tool, the design tool designs according to the scan data to obtain the appropriate abutment and crown, and sends the design data of the abutment and crown to the fabrication end; the fabrication section fabricates the abutment and crown according to the design data and returns the fabrication body, and the surgeon performs the tooth insertion operation.

[0066] For example, Figure 5 is a schematic diagram of another implantation process provided by an embodiment of this disclosure. As shown in Figure 5, the complete process of dental implantation is shown from the user's perspective, including three visits: Visit 1: The patient's first visit, CBCT and intraoral scan are taken, and then a guide plate is designed and made. A temporary tooth can also be designed and made. Visit 2: The implantation guide plate surgery is performed, an intraoral scan is performed using a drill, the final crown and abutment are designed and made, and a temporary tooth can also be put in. Visit 3: The final crown and abutment are put in.

[0067] Compared to the implantation process of the related technology in Figure 1, the implantation process of this solution can eliminate the step of waiting for the wound to heal after surgery and then scanning to obtain the scanning rod data, which is then used to fabricate the crown. This reduces the number of visits and the time spent on treatment, allowing patients to wear their teeth sooner.

Industrial Applicability

[0110] The technical solution provided in this application embodiment is applicable to the field of three-dimensional technology. In this application embodiment, after the drilling operation of the tooth drill bit, a scanning operation of the entire tooth into which the drill bit is inserted is adopted to obtain the drill bit scanning data. The crown and abutment designed based on the drill bit scanning data are the final crown and abutment, and the tooth is directly put on. This method not only avoids errors caused by deviations in the implantation surgery process and improves the accuracy of crown and abutment design, but also saves the step of waiting for the wound to heal and scanning again, reducing the time cost of implantation surgery and improving the efficiency of tooth putting.
