Description

TECHNICAL FIELD

[0001] The application belongs to the field of auxiliary medical technology, and particularly relates to a digital bone augmentation design method and system with real-time visualization of implant position. BACKGROUND

[0002] In the past decade, digital technology has made great progress in the field of oral implantation, which has gradually extended from the initial implant position planning to the preoperative digital design of soft and hard tissue volume. The design concept of "end-oriented" runs through the whole process. This concept requires that the design should be carried out first, and the best three-dimensional position of the implant is designed based on the ideal final restoration result, and then it is determined whether the related surgery of tissue augmentation (such as bone augmentation) and the most suitable augmentation range are needed according to the best three-dimensional position of the implant. In this process, the digital design of the final restoration and the implant design according to the restoration result have become the routine process in clinical practice.

[0003] The design of the best three-dimensional position of the implant and the design of the bone augmentation are usually carried out by different software. Common implant design software includes 3shape, etc., and bone augmentation design software includes EXOCAD dental, etc.

[0004] MAGICS software is a software for 3D printing data processing and construction preparation, which has various application functions for processing three-dimensional models. However, since there are more professional software for dental design (such as 3shape, EXOCAD dental, etc.), the MAGICS software has not been applied to the design of the best three-dimensional position of the implant or the design of the bone augmentation.

[0005] In the prior art, there is an incomplete open source problem between the data of the above-mentioned implant design software (such as 3shape, etc.) and the bone augmentation design software (such as EXOCAD dental, etc.), and the STL file of the implant cannot be exported, so the process of bone volume planning in the traditional process cannot see the designed implant position in real time, and only the experience of the designer can be used to design the non-real-time visible implant position in the software or to measure a few groups of data in the implant design interface and then to design approximately according to the measured data in the bone volume planning software.

[0006] It can be seen that the bone volume planning in the traditional process mainly relies on the experience of the designer to perform smearing operation in the software and cannot achieve real-time measurement. When the relationship between the bone volume and the implant needs to be understood, the STL file of the bone augmentation model needs to be exported again to fit with the implant design file. This makes the bone augmentation design in the prior art have the problems of complicated operation and high difficulty in achieving accurate design. Therefore, there is an urgent need in the field to develop a new design method which can realize the visualization of the design result of the best three-dimensional position of the implant and the design of the bone augmentation in the same software. SUMMARY

[0007] To solve the problems of the prior art, the application provides a digital bone augmentation design method and system with real-time visibility of implant position.

[0008] The digital bone augmentation design method with real-time visibility of implant position comprises the following steps:

[0009] Step 1: ideal restoration design of a tooth loss site is performed through bone augmentation design software to obtain ideal restoration data;

[0019] Preferably, the parameters of the implant include diameter, length and taper.

[0020] Preferably, in step 4, the moving process comprises the following steps: locking the sleeve hole in the axial direction so that the implant can only translate along the axial center line of the sleeve hole, and translating the virtual implant from the sleeve hole platform to its actual position according to the sleeve hole compensation amount during the design of the implant guide plate.

[0021] Preferably, in steps 1 to 6, the data file is in STL. file format.

[0026] The application also provides a computer readable storage medium having stored thereon a computer program for realizing the above-mentioned digital bone augmentation design method for real-time visualization of implant position.

[0027] A new implant design and bone augmentation design method is constructed, which can display the accurate position of the virtual implant in the jaw bone in the bone augmentation design software, overcome the problem of invisible implant position in the prior art digital bone augmentation process, and realize real-time visualization and measurable accurate bone augmentation design. The method can avoid blind design and the problem of repeated data import and export for comparison and verification after design, and can effectively improve the convenience and accuracy of bone augmentation design.

[0046] Embodiment 1: Digital bone augmentation design method and system based on implant position

[0047] The method of the embodiment, as shown in Figure 1 , comprises the following steps:

[0048] Step 1: According to the design requirements of the oral prosthesis, the ideal prosthesis data of the missing tooth site is designed through EXOCAD dental, and the ideal prosthesis data is obtained Figure 2 , and is exported as an STL. file.

[0049] Step 2: The STL. file of the ideal prosthesis data is input into 3shape, the CBCT data, the intraoral scanning data and the ideal prosthesis data are fitted, the position of the implant is planned according to the design requirements of the implant position Figure 3 , and the implant guide plate data is obtained, which is exported as an STL. file Figure 4 .

[0050] Step 3: The STL. file of the implant guide plate data is imported into the MAGICS software Figure 5 , the three-dimensional coordinate system of the implant guide plate is not changed throughout the process, the sleeve hole platform of the implant guide plate is taken as the reference plane, the sleeve hole axis is taken as the reference axis, a part is created by clicking, and the parameters (diameter, length, taper, etc.) of the implant to be placed are input to construct a virtual implant model Figure 6 .

[0051] Step 4: In the MAGICS software, the virtual implant model is moved to its actual position, specifically, the sleeve hole axial direction is locked so that the implant can only translate along the sleeve hole axial center line, and the virtual implant is translated from the sleeve hole platform to its actual position according to the sleeve hole compensation amount during the design of the implant guide plate Figure 7 and Figure 8 . The virtual implant and the implant guide plate are grouped, the spatial relative position of the two is locked, and the STL. file of the data is exported.

[0052] Step 5: The jaw bone model, the intraoral scanning data and the STL. file of the grouped data of the virtual implant and the implant guide plate exported in step 4 are input into EXOCAD dental, and the accurate position of the virtual implant in the jaw bone is obtained according to the morphology of the remaining teeth Figure 9 and Figure 10 .

[0053] Step 6, in EXOCAD dental, virtual bone augmentation painting operation is performed according to the accurate position of the virtual implant in the jaw bone, and the bone augmentation design is completed Figure 11-13 ).

[0054] The embodiment also provides a system for executing the above method, specifically comprising:

[0055] a bone augmentation design module integrated with a bone augmentation design software and configured to execute steps 1, 5 and 6;

[0056] an implant design module integrated with an implant design software and configured to execute step 2;

[0057] a virtual implant and implant guide plate combination module integrated with a MAGICS software and configured to execute steps 3 and 4.

[0058] Through the above method and system, virtual bone augmentation painting operation can be performed under the condition that the accurate position of the virtual implant in the jaw bone is visible. This makes the bone augmentation design more accurate and does not need to repeatedly import the design results into other software for comparison and verification.

[0059] Comparative Example 1: Existing implant and bone augmentation design method

[0060] In order to compare with the method of Example 1, the present comparative example provides step-by-step instructions for the existing implant and bone augmentation design method, specifically comprising:

[0061] Step 1: In EXOCAD dental, determine the ideal restoration design and export as an STL. file;

[0062] Step 2: In 3SHAPE, fit the preoperative STL. file and CBCT to determine the implant position;

[0063] Step 3: In 3SHAPE, measure the difference between the required bone volume key points and the existing bone volume and record (such as Figure 14 ) ;

[0064] Step 4: In EXOCAD dental, perform bone augmentation painting operation according to the recorded value and output the augmented STL. file (such as Figure 15 ) ;

[0065] Step 5: Reimport the augmented STL. file into 3SHAPE for fitting and check if the augmentation range meets the requirements;

[0066] Step 6: If step 5 meets the requirements, the process is completed, if not, repeat steps 4 and 5 until the desired augmentation requirements are met.

[0067] Through the above steps, it can be seen that in the design method of the prior art, the bone augmentation coating operation is performed according to the experience of the record data designer, the accuracy cannot be guaranteed, and the process of repeatedly importing and exporting files, verifying and modifying the design may be required, so that the design process is relatively cumbersome.

[0068] Through the above examples and comparative examples, it can be seen that the present application provides a more convenient and accurate digital bone augmentation design method and system for real-time visualization of implant position, which has a good application prospect.
