Description

Orthodontic surgery simulation method and apparatus thereof using triangular plane analysis}

The present invention relates to image processing technology, and more particularly, to digital orthodontic diagnosis and treatment planning technology.

Orthognathic surgery or bimaxillary surgery (two-jaw surgery) is one of the types of maxillofacial surgery that corrects irregularities in the jawbone and teeth. This is a surgical technique in which the lower jaw is fractured to be detachable, and then moved and fixed to fit the normal occlusion. Orthognathic surgery is generally performed in the form of two-jaw surgery in which both the maxilla and the mandible are operated at the same time or one-jaw surgery in which only one of the maxilla and mandible is operated.

For orthodontic surgery, digital orthodontic diagnosis and treatment methods that analyze patient data are being used. However, data analysis for orthodontics relies heavily on 2D data. Since the analysis items also use too many different points and lines, it is difficult to recognize the problem at a glance. Also, in the case of 2D 　 analysis, it is difficult to determine yaw, so it is often dependent on the operator's experience. In orthognathic surgery, even a small error can cause functional and aesthetic problems after surgery.

According to an embodiment, a method for simulating orthodontic surgery and an apparatus thereof are proposed to reduce errors occurring in the 2D analysis process for orthognathic surgery and allow the user to intuitively and simply identify problems.

Orthognathic surgery simulation method according to an embodiment includes acquiring clinical data of a patient for orthodontic surgery, extracting anatomical measurement points from the acquired clinical data, and selecting three predetermined measurement points from among the extracted measurement points. It includes the steps of generating a connected triangular plane, and displaying the generated triangular plane on clinical data.

Clinical data is 3D data, and in the step of generating a triangular plane, a 3D plane may be generated by connecting three measurement points on the clinical data in a 3D form.

In the step of generating the triangular plane, a triangular plane may be generated for each maxilla and mandible, and a triangular plane may be generated for each of the maxillary and mandibular rows.

In the step of displaying the generated triangular plane on the clinical data, the generated triangular plane may be divided into identifiable visual information and displayed.

In the step of displaying the generated triangular plane on clinical data, at least one of a midline, symmetry, and canting state of a patient for orthognathic surgery may be shown through the triangular plane.

The step of displaying the generated triangular plane on the clinical data includes displaying the triangular plane connecting both maxillary points (MR, ML) and U1 to provide at least one of a midline, symmetry, and canting state of the maxilla; and displaying a triangular plane connecting both sides U6 (U6R, U6L) and U1 to provide at least one of a midline, symmetry, and canting state of the maxillary dentition.

The step of displaying the generated triangular plane on the clinical data includes the steps of providing at least one of a midline, symmetry, and canting state of the mandible by displaying a triangular plane connecting both Go (GoR, GoL) and Me; -Displaying the triangular plane connecting Go-Me to provide at least one of the symmetrical states of the left and right mandibles, and displaying the triangular plane connecting both L6 and L1 to the midline, symmetry, and canting state of the mandibular row It may include at least one of providing at least one of.

Displaying the generated triangular plane on the clinical data may include displaying a triangular plane connecting both PCs (PCR, PCL) and Me to provide at least one of a midline, symmetry, and canting state of the chin. can

The orthodontic surgery simulation method includes the steps of providing the yaw state of the maxilla by displaying the ANS-PNS connection line, and vertically bisect the line connecting U6 on both sides and then mark the line through which the vertical bisector passes U1 to yaw the maxillary dentition. After providing the state, providing a yaw state of the mandible by marking a line through which the vertical bisector line passes through Me after perpendicular bisector of the line connecting both Go, and after perpendicular bisector of the line connecting both sides L6 The step of providing the yaw state of the mandibular dentition by marking the line through which the vertical bisector line passes L1, and the vertical bisector of the line connecting both PCs (PCR, PCL) The method may further include at least one of providing a yaw state of

The orthodontic surgery simulation method may further include extracting each analysis item based on a triangular plane, and displaying the patient's condition using the extracted analysis item.

The orthodontic surgery simulation method may further include displaying a screen for comparing the patient's current state with the normal state.

In the step of displaying a screen for comparing the patient's current state and normal state, the difference value between the current state and the normal state is divided into numerical information or identifiable visual information, or a triangular plane or line having a difference value can be identified. It can be displayed separately by visual information.

Orthognathic surgery simulation apparatus according to another embodiment includes a data acquisition unit that acquires clinical data of a patient for orthognathic surgery, extracts anatomical measurement points from the acquired clinical data, and connects three predetermined measurement points among the measurement points. It includes a control unit for generating a triangular plane, and an output unit for displaying the generated triangular plane on clinical data.

According to the orthodontic surgery simulation method and the apparatus according to an embodiment, it is possible to provide a three-dimensional schematic diagram for the user to easily recognize the analysis required for orthognathic surgery using a triangular plane. For example, at least one of a midline, symmetry, and canting state of a patient for orthognathic surgery may be shown through the displayed triangular plane.

In addition, as triangular planes are generated for each maxilla and mandible and triangular planes are generated for each maxillary and mandibular row, the patient's condition can be identified through the triangular planes for each bone and dentition.

Furthermore, by providing a screen comparing the difference between the patient's current state and the normal state, the post-operative appearance can be predicted.

In addition, in order to reduce errors in the process of using 2D analysis during orthodontic surgery, analysis is performed based on 3D data, and through 3D data, it is possible to confirm Yawing, which is difficult to confirm in 2D data.

Electronic devices include computers, notebook computers, laptop computers, tablet PCs, smart phones, mobile phones, personal media players (PMPs), personal digital assistants (PDAs), and the like.

The orthodontic surgery simulation apparatus 1 according to an embodiment uses 3D data analysis in order to solve the problem of errors occurring during the existing 2D data analysis and the complexity of the analysis. Before the actual operation, 3D simulation can be used to analyze the patient's current condition and predict the surgical outcome in advance.

Hereinafter, the configuration of the orthodontic surgery simulation apparatus 1 having the above-described characteristics will be described below with reference to FIG. 1 .

Referring to FIG. 1 , an orthodontic surgery simulation apparatus 1 according to an embodiment includes a data acquisition unit 10 , a storage unit 12 , a control unit 14 , an input unit 16 , and an output unit 18 . .

The data acquisition unit 10 acquires clinical data from orthodontic treatment patients. In particular, it is possible to obtain clinical data from a patient for orthodontic treatment. Clinical data required for orthodontic treatment include dental model data, CT data, panoramic data, face scan data, cephalometric X-ray data, frontal radiograph (PA X-ray) data, skull (Skull) data, etc. The CT data may be CBCT data.

The clinical data may be 3D data. In general, analysis for orthognathic surgery relies heavily on 2D data. In this case, it is difficult for the user to recognize the patient's problems at a glance because the analysis items also use too many measurement points and measurement lines. Accordingly, the present invention can perform analysis for orthognathic surgery using 3D data. By using 3D data, it is possible to present a clear standard that can reduce errors compared to 2D analysis. For example, it is possible to determine a yaw state that is difficult to determine on 2D data.

The storage unit 12 stores various data such as information necessary for performing an operation of the orthodontic surgery simulation apparatus 1 and information generated according to the operation. The storage unit 12 may provide data to the control unit 14 for data analysis of the control unit 14 .

The control unit 14 controls each component while continuously performing diagnosis and analysis of clinical data of orthodontic treatment patients, determination of patient status according to analysis, and orthodontic design process according to patient status through control by a computer program. In general, a clinical data diagnosis process, an analysis process, and a calibration design process are performed through separate programs, but the controller 14 according to an embodiment continuously performs a series of diagnosis, analysis, and calibration design processes through a single program. can be done In this case, the controller 14 may obtain a measurement value for each analysis item from the clinical data of the patient and diagnose the patient's condition using the measurement value for each analysis item. And it is possible to produce an orthodontic design according to the diagnosed patient condition.

In the analysis process, the control unit 14 extracts anatomical measurement points from the clinical data acquired through the data acquisition unit 10 . Anatomical measurement points can be divided into maxilla, mandible, maxillary dentition and mandibular dentition. For example, the measurement points of the maxilla include: PNS: Posterior nasal spine, ANS: Anterior nasal spine, MR: Maxillary point Right(the center of the concavity of the zygomatic process of the maxilla), ML: Maxillary point Left. The measurement points of the maxillary dentition include U6R: Maxillary first molar point Right, U6L: Maxillary first molar point Light, and U1: Maxillary central incisor point (between both sides). Measurement points of the mandible include CoR: Condylion Right, CoL: Condylion Left, GoR: Gonion Right, GoL: Gonion Left, Pog: Pogonion, PCR: Posterior chin point Right, PCL: Posterior chin point Left, Me: Menton. Measurement points of the mandibular dentition include L6R: Mandibular first molar point Right, L6L: Mandibular first molar point Left, and L1: Mandibular central incisor point (between both sides).

The control unit 14 generates a triangular plane connecting three predetermined measurement points among the extracted measurement points, and displays the generated triangular plane on the clinical data through the output unit 18 . The triangular plane is a 3D plane generated by connecting three measurement points on 3D clinical data. Therefore, it is possible to three-dimensionally diagram the patient's current state for orthognathic surgery through the triangular plane. For example, at least one of a patient's midline, symmetry, and canting state for orthognathic surgery may be shown to the user through a triangular plane. The user can grasp the patient's current state by looking at the triangular plane.

The controller 14 may generate a triangular plane for each maxilla and mandible. Also, a triangular plane may be created for each of the maxillary and mandibular rows. An example of generating a triangular plane by the controller 14 will be described later with reference to FIGS. 3 to 6 .

The control unit 14 may extract each analysis item based on the triangular plane, and display the patient's condition through the output unit 18 using the extracted analysis item.

The output unit 18 displays clinical data and information including a triangular plane generated through the control unit 14 on the screen. The output unit 18 may display the measurement value for the analysis item extracted through the control unit 14 on the screen. In this case, the output unit 18 may display a screen for comparing the patient's current state and the normal state together. For example, the difference value between the current state and the normal state is divided and displayed as numerical information or identifiable visual information, or a triangular plane or line having a difference value is divided and displayed as identifiable visual information. Accordingly, it is possible to predict the postoperative appearance through the difference between the patient's current state and the normal state.

The input unit 16 receives a user manipulation signal. For example, a normal value for the patient's normal state may be input from the user.
