[0043] Example 1

[0044] Figure 1 This is a flow chart of a method for constructing a dental implant restoration provided in the first embodiment of the present invention. This embodiment is applicable to the situation where a dental implant restoration structure is constructed based on a jaw structure. The method can be performed by a dental implant restoration construction device. The dental implant restoration construction device can be implemented in the form of hardware and / or software. The dental implant restoration construction device can be configured in an electronic device.

[0045] like Figure 1 As shown, the method includes:

[0046] S110. Construct a model of the jaw to be repaired based on the jaw medical model.

[0047] The medical model of the jaw can be a medical image obtained by scanning the jaw using a medical scanning device, or a medical image corresponding to the jaw extracted by scanning a human body including the jaw using a medical scanning device, or a medical image of the jaw obtained from medical data corresponding to the object whose jaw is to be repaired. The model of the jaw to be repaired can be a model of a defective jaw, or a three-dimensional model reconstructed from a jaw medical image. The model of the jaw to be repaired can include at least one of a maxillary model and a mandibular model.

[0048] Specifically, a jaw medical image is acquired and reconstructed to obtain a three-dimensional jaw model with defects, i.e., a jaw model to be repaired. Figure 2 shown.

[0049] S120. Determine a veneer contour according to the defect area in the jaw model to be repaired, and construct a veneer model according to the veneer contour.

[0050] The defect area may be the area corresponding to the defective part in the jaw model to be repaired. The veneer contour may be the contour of the defect area in contact with the jaw model to be repaired. For example, if the jaw model to be repaired is an upper maxillary model, the veneer contour is determined according to the upper surface of the defect area. If the jaw model to be repaired is a lower mandibular model, the veneer contour is determined according to the lower surface of the defect area. The veneer model may be a model with a certain thickness constructed according to the veneer contour, which can be installed on the jaw model to be repaired for subsequent model fixation. The schematic diagram of the veneer contour is as follows: Figure 3 shown.

[0051] Specifically, an area to be repaired is determined from the model of the mandible to be repaired as the defect area. A determination is made as to whether the defect area in the model of the mandible to be repaired is located in the maxillary or mandibular region. If the defect area is located in the maxillary region, a veneer contour is determined based on the upper surface of the defect area; if the defect area is located in the mandibular region, a veneer contour is determined based on the lower surface of the defect area. Furthermore, a veneer model is established based on the veneer contour and a preset thickness. The preset thickness can be a pre-set thickness, and the specific value can be set according to actual needs, such as 1 mm, and is not specifically limited in this embodiment.

[0052] It should be noted that the jaw model to be repaired may include one or more defect areas, the number of veneer contours is consistent with the number of defect areas, and the number of veneer models is consistent with the number of veneer contours.

[0053] S130. Determine the external repair model based on the jaw model to be repaired and the defect area.

[0054] The external repair model may be a model generated based on the outer contour area of ​​the jaw model to be repaired, and is used to fill the defect area of ​​the jaw model to be repaired.

[0055] Specifically, since the jaw is approximately symmetrical, the symmetrical part of the defect area can be determined from the jaw model to be repaired, and the external repair model corresponding to the defect area can be constructed based on the symmetrical part.

[0056] S140: Determine an inner repair model according to the outer repair model and a preset distance.

[0057] The preset distance may be a pre-set reduction distance, and the specific value may be set according to actual needs, such as 1 mm, etc., and is not specifically limited in this embodiment. The internal repair model may be a model used to fill the internal part of the external repair model.

[0058] Specifically, after the outer repair model is determined, the outer repair model is reduced according to a preset distance, and the obtained model is used as the inner repair model, so that the inner repair model can be placed inside the outer repair model.

[0059] S150: Construct a target restoration mesh model based on the veneer model, the external repair model, and the internal repair model.

[0060] The target restoration mesh model may be a model obtained by combining a veneer model, an external repair model, and an internal repair model in a preset manner.

[0061] Specifically, the external repair model is combined on the veneer model, the internal repair model is combined into the external repair model, and the combined model is used as the target restoration mesh model.

[0062] The technical solution of the embodiment of the present invention is to construct a model of the jaw to be repaired based on a jaw medical model, determine a veneer contour based on the defect area in the jaw model to be repaired, and construct a veneer model based on the veneer contour, determine an external repair model based on the jaw model to be repaired and the defect area, determine an internal repair model based on the external repair model and a preset distance, and construct a target restoration mesh model based on the veneer model, the external repair model and the internal repair model, thereby solving the problem of poor matching between the dental implant restoration and the jaw and the problem of uneven force on the dental implant restoration, and achieving the effect of improving the matching between the dental implant restoration and the jaw and improving the mechanical properties of the dental implant restoration.

[0063] Example 2

[0064] Figure 4This is a flow chart of a method for constructing a dental implant restoration, provided in Example 2 of the present invention. Based on the above embodiments, the specific construction methods for the external repair model and the target restoration mesh model can be found in the detailed description of this technical solution. The explanations of terms that are identical or corresponding to those in the above embodiments are not repeated here.

[0065] like Figure 4 As shown, the method includes:

[0066] S210. Construct a model of the jaw to be repaired based on the jaw medical model.

[0067] S220: Determine a veneer contour according to the defect area in the jaw model to be repaired, and construct a veneer model according to the veneer contour.

[0068] S230. Determine a symmetry plane based on the jaw model to be repaired.

[0069] The symmetry plane may be the left-right symmetry center of the jaw model to be repaired.

[0070] Specifically, after obtaining the model of the jaw to be repaired, a structural analysis can be performed on the model of the jaw to be repaired to determine the symmetry plane so that the subsequently repaired jaw and the implanted tooth are bilaterally symmetrical.

[0071] S240. Determine a control part model corresponding to the defect area with the symmetry plane as the symmetry center.

[0072] Since the jaw can be approximately regarded as symmetrical, the control partial model can be a partial model of the jaw model to be repaired that is symmetrical to the defect area.

[0073] Specifically, the defect area is symmetrically processed with the symmetry plane as the symmetry center, and the resulting area is the control area. Then, the part of the jaw model to be repaired that overlaps with the symmetry area is used as the control part model.

[0074] S250, symmetric the control part model along the symmetry plane to obtain an external repair model.

[0075] Specifically, by symmetrizing the control part model according to the symmetry plane, a model that is mirror-symmetrical to the symmetric part model can be obtained. This model is the external repair model. The schematic diagram of the external repair model is as follows: Figure 5 shown.

[0076] S260: Determine an inner repair model according to the outer repair model and the preset distance.

[0077] S270: Perform mesh processing on the inner repair model according to the first preset structure to obtain a first mesh model.

[0078] The first preset structure may be a predetermined three-dimensional structure, so that the formed first mesh model can match the three-dimensional shape of the jaw. For example, the first preset structure may be a truncated octahedron structure. The schematic diagram of the truncated octahedron structure is as shown in FIG. Figure 6 The first grid model can be an inner repair model of the grid structured processing.

[0079] Specifically, mesh processing is performed on the inner repair model, that is, the inner repair model is converted into a mesh model composed of a first preset structure, that is, the first mesh model.

[0080] For example, by using the command Create Unit Graph, the inner mesh of the truncated octahedron structure can be generated based on the inner patch model to obtain the first mesh model. The schematic diagram of the inner mesh is as follows: Figure 7 shown.

[0081] S280: Perform mesh processing on the outer repair model according to the second preset structure to obtain a second mesh model.

[0082] The second preset structure may be a predetermined three-dimensional structure, so that the formed second mesh model can match the three-dimensional structure of the jaw. For example, the second preset structure may be a cube structure. The second mesh model may be an external repair model processed by mesh structuring.

[0083] Specifically, the outer repair model is meshed, that is, the outer repair model is converted into a mesh model composed of a second preset structure, that is, a second mesh model. The schematic diagram of the second mesh model is as follows Figure 8 shown.

[0084] Exemplarily, based on the outer patch model, the command Create Quad Graph is used to generate an outer mesh of a cube structure to obtain a second mesh model.

[0085] S290: Construct a target restoration mesh model based on the veneer model, the first mesh model, and the second mesh model.

[0086] Specifically, the second mesh model is combined on the veneer model, the first mesh model is combined into the second mesh model, and the combined model is used as the target restoration mesh model.

[0087] Optionally, the target restoration mesh model may be constructed based on the veneer model, the first mesh model, and the second mesh model by the following steps:

[0088] Step 1: Construct a jaw mesh model based on the first mesh model and the second mesh model.

[0089] The mandibular mesh model may be a model obtained by combining the first mesh model and the second mesh model.

[0090] Specifically, the first mesh model is placed inside the second mesh model and the two are connected. The connected model is used as the mandibular mesh model. The schematic diagram of the mandibular mesh model is as follows: Figure 9 shown.

[0091] Based on the above example, the jaw mesh model can be constructed according to the first mesh model and the second mesh model in the following manner:

[0092] A first positional relationship is determined based on the first mesh model and the defect area, and a second positional relationship is determined based on the second mesh model and the defect area; an installation positional relationship between the first mesh model and the second mesh model is determined based on the first positional relationship and the second positional relationship; and a Boolean sum operation is performed on the first mesh model and the second mesh model based on the installation positional relationship to obtain a mandibular mesh model.

[0093] The first positional relationship may be the positional relationship between the first grid model and the defective area, the second positional relationship may be the positional relationship between the second grid model and the defective area, and the installation positional relationship may be the positional relationship between the first grid model and the second grid model.

[0094] Specifically, the outer contour of the first mesh model should be consistent with the defect area. The first mesh model is placed in the defect area to determine the first positional relationship. The outer contour of the second mesh model is reduced by a preset distance compared to the defect area. When the distance between the outer contour of the second mesh model and the outer contour of the defect area is the preset distance, the second positional relationship is determined. Taking the defect area as a reference, the installation positional relationship between the first mesh model and the second mesh model can be determined according to the first positional relationship and the second positional relationship, that is, how to place the first mesh model inside the second mesh model. The first mesh model and the second mesh model are placed according to the installation positional relationship, and a Boolean sum operation is performed after placement to obtain a combined model, which is the mandibular mesh model.

[0095] Exemplarily, the mesh data structure of the first mesh model, such as the graph list, is dragged into the mesh data structure of the second mesh model, and the first mesh model and the second mesh model are connected by the command Connect Graphs to obtain the jaw mesh model.

[0096] Step 2: Construct a mandibular solid model based on the mandibular mesh model and preset wire diameter.

[0097] The preset wire diameter can be the diameter of the mesh structure used to construct the mandibular solid model. For example, if the mesh structure is a cylinder, the preset wire diameter is the cylinder's diameter. The mandibular solid model is the model after the mesh portion of the mandibular mesh model has been solidified.

[0098] Specifically, based on the mandibular mesh model, a preset wire diameter is assigned to the mesh part of the mandibular mesh model, and the mandibular mesh model is converted into a mandibular solid model. The schematic diagram of the mandibular solid model is shown in FIG. Figure 10 shown.

[0099] For example, by using the command Linear Gradient Thickness, the jaw mesh model is given a wire diameter of 0.5 mm.

[0100] Step 3: Perform Boolean summation on the mandibular solid model and the veneer model to obtain the target restoration mesh model.

[0101] Specifically, through the Boolean sum calculation method, the mandibular solid model can be installed on the veneer model, and the obtained model can be used as the target restoration mesh model.

[0102] Optionally, after constructing the target restoration mesh model, an implant slot may be set on the target restoration mesh model to facilitate subsequent implant placement, which may specifically include the following steps:

[0103] Step 1: Determine the planting slot location based on the predetermined occlusion.

[0104] The occlusal condition may be occlusal data determined based on pre-collected occlusal data, such as occlusal position, occlusal force, etc. The implant position may be an occlusal position where the occlusal force is greater than a preset force.

[0105] Specifically, the occlusal positions within the defect area and the corresponding occlusal forces can be determined based on pre-collected occlusal data. Furthermore, by analyzing the occlusal positions and occlusal forces, the implant placement, i.e., the implant slot location, can be determined.

[0106] Step 2: According to the position of the implant slot, holes are punched on the target restoration mesh model to update the target restoration implant model.

[0107] Specifically, the position of the hole to be drilled corresponding to the implant slot position is determined on the target restoration mesh model, and the hole processing is performed on the position of the hole to be drilled, and the model after the drilling processing is used as the new target restoration implant model. The schematic diagram of the updated target restoration implant model is as follows Figure 11 The schematic diagram of installing the target restoration implant model into the defect area is shown in Figure 12shown.

[0108] Optionally, the steps of setting the implant slot position and drilling holes according to the implant slot position can also be performed after obtaining the mandibular mesh model. Specifically, the steps can be: determining the implant slot position according to a predetermined occlusal condition; drilling holes on the mandibular mesh model according to the implant slot position, and updating the mandibular mesh model. For example, the schematic diagram of setting the implant slot on the mandibular mesh model is as follows: Figure 13 shown.

[0109] The technical solution of the embodiment of the present invention is to determine a symmetry plane based on the model of the jaw to be repaired, determine a control part model corresponding to the defect area with the symmetry plane as the symmetry center, and symmetrize the control part model according to the symmetry plane to obtain an external repair model to improve the matching degree between the dental implant restoration and the jaw, determine an internal repair model based on the external repair model and a preset distance, mesh the internal repair model according to the first preset structure to obtain a first mesh model, mesh the external repair model according to the second preset structure to obtain a second mesh model, and construct a target restoration mesh model based on the veneer model, the first mesh model and the second mesh model, thereby solving the problem of uneven force on the dental implant restoration and achieving the effect of improving the mechanical properties of the dental implant restoration through inner and outer mesh models and different mesh structures.
