Since in some clinical examples, a patient with dentition missing has an original complete denture because, for example, complete denture repair has been performed before, one of the innovative ideas of the present application is that, for the complete digital implant guide plate required to be used in the complete denture implant scheme designed by such a patient, three-dimensional data of the original complete denture can be utilized in the design of the complete digital implant guide plate, and the efficiency can be greatly improved compared with the implant scheme and the complete implant guide plate which are completely re-designed by scanning the oral cavity of the patient; secondly, the digital full-mouth planting guide plate is used by doctors to guide the planting operation, the visual planting scheme can be displayed for patients through the display, the communication is visual and efficient, the requirements of clinicians and patients on aesthetics and functions are met, and the predictability of the repairing effect is improved.

Fig. 1 is a schematic flow chart showing a method for manufacturing a full-aperture digital planting guide plate according to an embodiment of the present application.

The manufacturing method comprises the following steps:

step S101: and acquiring first three-dimensional data of the original complete denture of the patient.

In some examples, the first three-dimensional data may be three-dimensional data of an original conventional complete denture of the patient scanned by a three-dimensional scanning device (e.g., a laser scanner).

Further alternatively, the first three-dimensional data may be directly in STL format or converted into STL format for subsequent 3D printing of dentures. Among them, the STL format file is a file format for representing a triangular mesh in a computer graphics application system, and is widely used because its file format is very simple. Almost all 3D printers on the market print production by recognizing STL models.

Alternatively, in some examples, the first three-dimensional data may be obtained from three-dimensional data stored at the time of original conventional complete denture design or fabrication.

In a preferred example, the acquiring first three-dimensional data of the original complete denture of the patient further comprises:

a: detecting whether the original complete denture is matched with the patient;

b: and under the condition of matching, obtaining first three-dimensional data of the original complete denture and executing subsequent steps.

In case of no match, the subsequent steps may not be performed. This step is to determine whether the retention of the patient's original full denture matches the user, and thus whether its corresponding first three-dimensional data is available. The basis for determining whether to match may be, for example: checking the information of the judgment result of one or more conditions of whether the original complete denture of the patient meets the required conditions and whether the original complete denture meets the conditions of being attached to soft tissue after being worn in the mouth, having no tilting, rotating and discomfort for the patient; in the case where some or all of these conditions are satisfied, it can be determined that the three-dimensional data of the original complete denture is available.

From this, original complete denture just can remain to utilize original complete denture to restore for the planting back again and provide probably, simplified the repair procedure after the planting greatly, the patient adapts to new complete denture more fast, and the comfort level promotes greatly.

Step S102: and manufacturing a radiation guide plate according to the first three-dimensional data of the original complete denture.

In one example, step S102 includes:

a: and manufacturing a temporary complete denture according to the first three-dimensional data of the original complete denture.

In this step, the STL format file converted from the first three-dimensional data may be imported into a 3D printer to print a temporary complete denture, i.e., a dental model. Alternatively, the temporary complete denture may be made of, for example, a resin material.

B: several hemispherical defects were made on the bucco-lingual side of the temporary complete denture polishing surface and bonded with zirconia beads to form the radiation guide plate.

Illustratively, 5-7 hemispherical defects having a depth of 2mm and a diameter of 2mm are formed on the bucco-lingual side of the polished surface of the denture, and zirconia beads having the same diameter are bonded thereto.

Step S103: acquiring first three-dimensional image data acquired under the same image acquisition parameters and obtained by placing the radiation guide plate in the mouth of the patient, and second three-dimensional image data obtained by placing the radiation guide plate outside the mouth of the patient.

Specifically, the collecting mode includes: the CT scanning is carried out on the acquired object through a CT scanning device. Preferably, the CT scanning device may be a CBCT device. CBCT is called Cone beam CT for short, i.e. Cone beam CT. As the name suggests, a cone-beam projection computed tomography apparatus, whose principle is that an X-ray generator makes a circular DR (digital projection) around a projection with a low dose (usually, a bulb current is around 10 ma). Then, the data obtained in the intersection after digital projection for multiple times (180-360 times, different according to different products) around the projection body are 'recombined' in the computer, and the three-dimensional image data is obtained after the reconstruction.

Illustratively, the first three-dimensional image data and the second three-dimensional image data may be in, for example, DICOM format. Among them, dicom (digital Imaging and Communications in medicine), which is an international standard for medical images and related information, is an international standard (ISO 12052). It defines a medical image format that can be used for data exchange with a quality that meets clinical needs.

Step S104: and carrying out jaw three-dimensional reconstruction according to the first three-dimensional image data, and carrying out data registration of a radiation guide plate and the jaw by combining the second three-dimensional image data to obtain a jaw three-dimensional model.

For example, the first three-dimensional image data and the second three-dimensional image data may be imported into modeling design software (e.g., mics software) for jaw three-dimensional reconstruction.

Illustratively, the overlapping registration of the first three-dimensional image data and the second three-dimensional image data may be performed through the radiation guide's blocking points (i.e., set registration landmark points), thereby obtaining a jaw three-dimensional model.

After step S104, the method may further include: at least the bone height and the bone width corresponding to the three-dimensional model of the jaw bone are measured for the design of an implant plan.

Step S105: and manufacturing the full-mouth digital implantation guide plate according to an implantation scheme designed according to the jaw three-dimensional model.

Specifically, the implant scheme can be designed according to a jaw bone three-dimensional model or a jaw bone three-dimensional model combined with specific conditions in a patient's mouth, and the design and the manufacture of the full-mouth digital implant guide plate can be completed, wherein the manufacture can be to send design data (for example, STL format) of the full-mouth digital implant guide plate to a 3D printer and the like for printing, so as to obtain the solid full-mouth digital implant guide plate.
