[0028] In order to make the personnel in the technical field better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0029] It should be noted that the terms "first", "second", and the like in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The case of "target", "original" and the like is similar, and will not be described here.

[0030] Before introducing the embodiments of the present application, the related content described in the background art will be exemplarily described, so as to better understand the implant placement method described in the embodiments of the present application.

[0031] At present, when implanting an implant, a target hole is punched in the alveolar bone, and the implant is implanted in the target hole. However, when the thickness of the alveolar bone is less than the length of the implant, as shown in FIG. 1, the implant 4 cannot be completely placed in the target hole. At this time, the maxillary sinus 1 needs to be lifted up by the target filler 2 to deepen the depth of the target hole, so that the implant 4 can be completely placed in the target hole and the maxillary sinus is not damaged. However, in the related art, the alveolar bone is punched, the target filler is filled, and the implant is placed only by the experience of the doctor, which is easy to cause damage to the maxillary sinus, and the safety is low. Figure 1

[0032] Figure 2 ​is a flow chart of a dental implant placement method provided in an embodiment of the present application. The embodiment can be applicable to the case of dental implant placement, especially the case of dental implant placement requiring maxillary sinus lifting. The method can be performed by a dental implant placement device provided in an embodiment of the present application, which can be implemented in the form of software and / or hardware, and can be integrated on an electronic device, which can be various user terminals or servers.

[0033] Referring to Figure 2 The method of the embodiment of the present application specifically includes the following steps:

[0034] S110, obtaining a maxillary sinus image of a target object to be placed with a dental implant, and segmenting a target position image containing a placement position of the dental implant in the maxillary sinus image.

[0035] The target object can be understood as a patient to be placed with a dental implant.

[0036] The target position image can be understood as an image at the placement position of the dental implant in the maxillary sinus image.

[0037] For the target object, optionally, a medical diagnostic instrument such as a computed tomography, magnetic resonance imaging, and positron emission tomography instrument can be used to scan or photograph the target object, and the maxillary sinus image of the target object can be obtained by processing, and the target position image containing the placement position of the dental implant can be segmented from the maxillary sinus image.

[0038] S120, determining a drilling safety depth of drilling a hole at the placement position based on the target position image, and in the case that a dental implant length of the dental implant is greater than the drilling safety depth, determining a placement safety depth of placing the dental implant at the placement position based on the target position image and the dental implant length, so that a controller in a robot performs the following S130 and S140 based on the drilling safety depth and the placement safety depth to realize the dental implant placement.

[0039] The drilling safety depth can be understood as a safety depth of drilling a hole at the placement position, and in order to ensure the safety of drilling a hole, the drilling depth should not exceed the drilling safety depth when drilling a hole so as not to drill through the maxillary sinus.

[0040] The placement safety depth can be understood as a safety depth of the implant beyond the alveolar bone when the implant is placed in the borehole. After the depth of the maxillary sinus is increased, in order to avoid damage to the maxillary sinus caused by the implant being placed too deeply when the implant is placed, the placement depth of the implant when placed cannot exceed the placement safety depth. Optionally, the alveolar bone thickness at the placement position can be determined based on the target position image; the implant length of the implant is subtracted from the alveolar bone thickness to obtain the placement safety depth of the implant at the placement position. In this way, the implant can be placed in the borehole just in the case of the least increase of the depth of the maxillary sinus.

[0041] The drilling safety depth of the borehole at the placement position can be determined based on the target position image. Optionally, the drilling safety depth can be determined according to each tissue image in the target position image. In the case that the implant length of the implant is greater than the drilling safety depth, the maxillary sinus needs to be increased. At this time, the placement safety depth of the implant at the placement position needs to be determined based on the target position image and the implant length, so as to avoid exceeding the increased depth of the maxillary sinus when the implant is placed, and causing damage to the maxillary sinus.

[0042] Further, the controller in the robot can control the mechanical arm in the robot to perform further placement work by obtaining the drilling safety depth and the placement safety depth. In other words, S110 and S120 can be performed by the electronic device, and S130 and S140 can be performed by the controller.

[0043] S130, based on the drilling safety depth, control the mechanical arm in the robot to drill a borehole at the placement position to obtain a target hole, and based on the placement safety depth, control the mechanical arm to increase the depth of the maxillary sinus at the placement position through the target hole to deepen the hole depth of the target hole.

[0044] The controller can control the mechanical arm in the robot to drill a borehole at the placement position to obtain a target hole according to the obtained drilling safety depth. In the case that the implant length of the implant is greater than the drilling safety depth, the controller can also control the mechanical arm to increase the depth of the maxillary sinus at the placement position through the target hole based on the placement safety depth to deepen the hole depth of the target hole.

[0045] S140, based on the placement safety depth, control the mechanical arm to place the implant in the target hole with the deepened depth.

[0046] After the target hole is deepened, the controller can control the mechanical arm to place the implant in the target hole with the deepened depth based on the placement safety depth. Optionally, the depth of the implant when placed beyond the alveolar bone is less than or equal to the placement safety depth, so as to avoid being placed too deeply and exceeding the depth of the deepened target hole, and causing damage to the maxillary sinus.

[0047] The technical solution in the embodiments of the present application, by aiming at the target object to be implanted, obtains the maxillary sinus image of the target object, and segments the target position image containing the placement position of the implant in the maxillary sinus image, to further determine the accurate drilling safety depth and placement safety depth through the target position image; based on the target position image, the drilling safety depth of drilling at the placement position is determined, and in the case that the implant length of the implant is greater than the drilling safety depth, the placement safety depth of placing the implant at the placement position is determined based on the target position image and the implant length, so that the controller in the robot performs the following two steps based on the drilling safety depth and the placement safety depth to realize the implant placement: based on the drilling safety depth, the mechanical arm in the robot is controlled to drill at the placement position to obtain the target hole, and based on the placement safety depth, the mechanical arm is controlled to lift the maxillary sinus depth of the maxillary sinus at the placement position to deepen the hole depth of the target hole, and then based on the placement safety depth, the mechanical arm is controlled to place the implant in the target hole with deepened depth, through the operation of the mechanical arm, the automation of the implant planting process is realized, and the precision is improved. The above technical solution determines the drilling safety depth and the placement safety depth through the obtained target position image, and plants the implant based on the drilling safety depth and the placement safety depth by using the mechanical arm, which ensures the safety of the implant planting.

[0048] An optional technical solution, aiming at the target object to be implanted, obtains the maxillary sinus image of the target object, comprising: obtaining the oral medical image of the target object aiming at the target object to be implanted; performing three-dimensional reconstruction on the oral medical image to obtain a reconstructed medical image; performing maxillary sinus segmentation on the reconstructed medical image to obtain the maxillary sinus image of the target object.

[0049] Among them, the oral medical image of the target object can be obtained by a medical diagnostic instrument, and the three-dimensional reconstructed medical image can be obtained by three-dimensional reconstruction of the oral medical image. Further, different oral parts of the patient can be segmented from the reconstructed medical image through threshold segmentation and / or machine learning algorithm, so as to obtain the maxillary sinus image of the target object.

[0050] The above technical solution can segment to obtain an accurate three-dimensional maxillary sinus image, which provides image basis for further quantization of the drilling safety depth and the placement safety depth.

[0051] In another optional technical solution, the target position image containing the placement position of the implant in the maxillary sinus image is segmented, including: determining the placement position of the implant based on at least one of the activity range of the mechanical arm, the alveolar bone width and depth of the target object, the bone density of the target object, and the volume of the implant by using the pre-trained implant planning algorithm; and determining the target position image from the maxillary sinus image based on the placement position.

[0052] The implant planning algorithm can be understood as a pre-trained automatic planning algorithm, which can automatically plan and place the implant. Optionally, it can be trained and generated by different maxillary sinus lifting planning schemes.

[0053] The implant planning algorithm can be used to automatically determine the placement position of the implant based on factors such as the activity range of the mechanical arm, the alveolar bone width and depth of the target object, the bone density of the target object, and the volume of the implant, and to determine the target position image by obtaining the image at the placement position in the maxillary sinus image.

[0054] The above technical solution can automatically determine the placement position of the implant, and realize rapid planning of implantation.

[0055] Figure 3 is a flowchart of another implant placement method provided in the embodiments of the present application. The present embodiment is optimized based on the above technical solutions. In the present embodiment, optionally, based on the target position image, the drilling safety depth of drilling a hole at the placement position is determined, including: determining the first vertical distance between the placement position and the target interface based on the target position image, wherein the target interface is the interface between the cartilage tissue at the placement position and the maxillary sinus; and obtaining the drilling safety depth of drilling a hole at the placement position based on the first vertical distance. Wherein, the explanations of the same or corresponding terms as in the above embodiments are not repeated here.

[0056] Referring to Figure 3 The method of the present embodiment can specifically include the following steps:

[0057] S210, for a target object to be implanted, obtaining a maxillary sinus image of the target object, and segmenting a target position image containing a placement position of the implant in the maxillary sinus image.

[0058] S220, based on the target position image, determining the first vertical distance between the placement position and the target interface, wherein the target interface is the interface between the alveolar bone at the placement position and the maxillary sinus.

[0059] The target interface can be understood as the interface between the alveolar bone and the maxillary sinus, and the alveolar bone is adjacent to the maxillary sinus in the maxillary sinus image. When implanting the implant, the alveolar bone should be avoided to be drilled through and the maxillary sinus should be avoided to be drilled when drilling a hole.

[0060] The first vertical distance can be understood as a vertical distance between the placement position and the target interface. Since the drilling is vertical, the vertical distance between the placement position and the target interface needs to be determined.

[0061] In S230, a drilling safety depth of drilling at the placement position is obtained based on the first vertical distance.

[0062] After the first vertical distance is obtained, the drilling safety depth of drilling at the placement position can be obtained based on the first vertical distance. Alternatively, the first vertical distance can be directly used as the drilling safety depth, or the first vertical distance can be reduced by a preset buffer distance to obtain the drilling safety depth. The preset buffer distance can be controlled and judged by a doctor, and after the judgment is completed, the first vertical distance is reduced by the preset buffer distance to obtain the drilling safety depth. In this way, the drilling of the maxillary sinus caused by errors can be avoided, and the safety of drilling can be further improved.

[0063] In S240, when the implant length of the implant is greater than the drilling safety depth, a placement safety depth of placing the implant at the placement position is determined based on the target position image and the implant length, so that a controller in the robot performs S250 and S260 based on the drilling safety depth and the placement safety depth to realize implant placement.

[0064] In S250, a mechanical arm in the robot is controlled to drill at the placement position based on the drilling safety depth to obtain a target hole, and the mechanical arm is controlled to lift a maxillary sinus depth of the maxillary sinus at the placement position through the target hole based on the placement safety depth to deepen a hole depth of the target hole.

[0065] In S260, the mechanical arm is controlled to place the implant in the target hole with the deepened depth based on the placement safety depth.

[0066] The technical scheme of the embodiment of the present application can quantize the drilling safety depth based on the first vertical distance between the placement position and the target interface in the target position image, and improve the safety of drilling.

[0067] An alternative technical scheme includes: controlling the mechanical arm to fill a target filler into the target hole and applying pressure to the target filler filled in the target hole, so that the target filler penetrates through the alveolar bone with a preset buffer distance and enters the target interface; and controlling the mechanical arm to continue filling the target filler into the target interface through the target hole based on the placement safety depth, so that the target filler lifts the maxillary sinus depth of the maxillary sinus at the placement position to deepen the hole depth of the target hole.

[0068] In the case that the implant length of the implant is greater than the drilling safety depth, the depth of the maxillary sinus needs to be first lifted, and the controller needs to control the mechanical arm to fill the target filling material into the target hole, and the target filling material can be bone powder, and the mechanical arm needs to apply pressure to the target filling material filled in the target hole to make the target filling material penetrate the alveolar bone of the preset buffer distance and enter the target junction, and the controller needs to control the mechanical arm to continue filling the target filling material into the target junction through the target hole based on the placement safety depth, so that the target filling material lifts the maxillary sinus to increase the maxillary sinus depth of the placement position, to deepen the hole depth of the target hole, so that the implant can be completely implanted in the target hole.

[0069] The above technical solution can more accurately and stably lift the depth of the maxillary sinus by controlling the mechanical arm to fill the target filling material into the target hole based on the placement safety depth.

[0070] In order to better understand the above technical solutions, the following will be exemplarily described in combination with specific examples, and the specific implanting steps are as follows:

[0071] S1, import the oral medical image of the target object into the image processing module.

[0072] S2, the image processing module performs three-dimensional reconstruction on the oral medical image of the target object.

[0073] S3, after three-dimensional reconstruction, the image processing module automatically segments the maxillary sinus image.

[0074] S4, in the case that the implant length of the implant is greater than the alveolar bone thickness, the maxillary sinus lifting operation is selected in the implanting operation.

[0075] S5, using the pre-trained implant planning algorithm, based on at least one of the activity range of the mechanical arm, the alveolar bone width and depth of the target object, the bone density of the target object, and the volume of the implant, the position optimization is automatically planned, and finally the implant position scheme is automatically generated.

[0076] S7, after the implant scheme is generated, the doctor will determine the final scheme, and after confirming the scheme, according to the target position image of the placement position, the image processing module will automatically generate the drilling safety depth and the placement safety depth according to the target position image, and automatically deploy it to the controller of the mechanical arm.

[0077] S8, the controller controls the mechanical arm to use the drilling safety depth in the drilling mode, if the mechanical arm drill needle drills the drilling safety depth to the drilling safety depth, the drilling is stopped, then the mode is switched to the implant placement mode, the mechanical arm switches the safety distance judgment to the placement safety depth at this time, fills the bone powder (i.e. target filling) into the target hole to improve the maxillary sinus depth, and places the implant, and the operation is completed.

[0078] The specific example automatically generates the safety depth and the placement safety depth through the image processing module, and controls the mechanical arm to complete the implantation of the implant based on the safety depth and the placement safety depth, thereby improving the safety of the implantation of the implant.
