[0001] DENTAL IMPLANT PLANNING METHOD, APPARATUS AND RECORDING MEDIUM THEREOF [0002]

The present invention relates to a dental implant planning method, an apparatus therefor, and a recording medium on which the method is installed. More specifically, the present invention relates to a method for determining the size and position of implant objects in planning a dental implant, .

Prior to the procedure, the dental implant treatment is subjected to an implant planning process that determines the dimensions, type, position, orientation, and shape of the implants appropriate to the patient's bone condition.

First, the image acquisition equipment is used to acquire an image that can identify the amount and quality of the patient's jaw and tooth bone such as X-ray, CT, MRI, and panorama, and select the type and size of the implant suitable for the patient's condition, Orientation, shape, etc. are simulated through a software program.

Most of the software programs for dental implant planning are implemented to select and place fixtures among the objects constituting the implants. However, in actual implant placement and fabrication, the crown is not a part that can easily move, rotate, or control the depth of the crown, so the orientation of the fixture is often determined after first adjusting the crown position. If the fixture's position is specified first, the position of the crown may be a position where the crown is likely to be broken or a position where the abutment connecting the crown and the fixture can not be used. Therefore, it is necessary to apply a software program for implant planning which can be applied safely in clinical practice by applying the same clinical procedure to implant simulation as it is.

In addition, a conventional software program for dental implant planning uses a method of selecting a desired fixture from an implant library and performing a simulation. In this case, in order to replace the inserted fixture or replace it with another fixture, it is troublesome to select a fixture that can fit the width and length after measuring the width and length of the portion to be inserted.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

1 is a control block diagram of an apparatus for planning a dental implant according to a first embodiment of the present invention. Referring to FIG. 1, an apparatus for planning a dental implant according to a first embodiment of the present invention includes an image generating unit 10, a user interface unit 20, a positioning unit 30, an object generating unit 40, A scale UI generating unit 23b, and an object modifying unit 50. [

The image generation unit 10 generates a multidimensional image model for a patient's tooth arrangement for implant planning, wherein a model of a patient's tooth arrangement is available in both 2D and 3D based models.

A model of the patient's tooth arrangement is generated based on the patient's chin or tooth image, which can be constructed by matching X-ray, CT, MRI, panoramic image and scan prosthesis or individually digitized prosthesis to anatomical structures . In this embodiment, a panorama image is generated based on a CT image.

The apparatus for planning a dental implant according to the first embodiment of the present invention further includes a patient library (not shown) storing images or models related to a patient's jaw or teeth, A video or a model corresponding to the user's selection is displayed on the screen.

The user interface unit 20 includes a user input unit including a mouse, a keyboard, a button, a keypad, and the like, and a GUI generation unit 23 for generating a GUI on the screen.

FIG. 2 shows an example of an implementation screen of the implant planning apparatus according to the first embodiment of the present invention. Referring to FIG. 2, the implementation screen of the implant planning apparatus displays a patient image area (for example, a panoramic area) related to a tooth arrangement of a patient in the center, and an axial screen and a 3D screen . The implementation plan of the implant planning apparatus of FIG. 2 includes a plurality of user GUI menus, and most GUI menus are represented by icons. At the top of the screen, setting icon menus for simulating a virtual object are arranged, and a tooth UI with a tooth shape in which a tooth number is described is displayed above and below the panoramic area. This arrangement of the screens is merely an example, and it goes without saying that it can be implemented differently according to the embodiment.

2, the user can select a position where the implant is to be placed by selecting a tooth shape indicated by a tooth number in the teeth UI. Then, both ends (two points) of the maximum outline of the position where the implant is to be placed (for example, the wind and the limb) can be selected from the multidimensional image of the patient to designate the size and the like of the maximum wind and margin of the crown.

According to another embodiment of the present invention, a tooth selection unit (not shown) may be further provided for selecting a position where the implant is to be placed by an automatic algorithm. For example, a tooth selection unit (not shown) detects a tooth missing area using a threshold value such as pixel brightness in a multidimensional image related to a tooth arrangement, and detects the maximum outline (wind and limb) of the tooth loss area, Points can be selected. Here, the detection of the tooth loss region and the selection of the maximum outline can be performed by various image analysis algorithms.

The position determining unit 30 determines the size, position, fixture position, and orientation of the virtual crown based on the distance and inclination of the two points selected or automatically extracted by the user. The positioning unit 30 determines the maximum angle of the crown to be positioned at two points selected by the user and determines the rotational angle of the virtual crown and the direction of the fixture based on the inclination of the two points. Accordingly, in the present invention, since the size and rotation angle of the crown are determined, and the position and orientation of the fixture are determined, the process of the clinic can be directly applied to the implant simulation, thereby improving the accuracy of the implant planning.

The object creating unit 40 creates the implant objects and superimposes them on the multi-dimensional image of the patient. Here, the implant object refers to an object constituting an implant. In a narrow sense, it includes a virtual crown and a fixture, and in a broad sense, it can include all kinds of implant objects such as an abutment and a sleeve.

The apparatus for planning a dental implant according to the first embodiment of the present invention may further include an implant library (not shown). The implant library (not shown) may include various implant objects by company, type, size, Is stored.

The object generating unit 40 arranges the virtual crown and the fixture on the multidimensional image of the patient based on the size and position determined by the position determining unit 30. The object generating unit 40 may generate an implant object corresponding to the size or the selection in the implant library when the object is created. In the case of a virtual crown, a size is created based on two points selected by the user. In the case of a fixture, an object corresponding to a model set by a user in advance as a default value can be created and displayed. For example, a product of a product group of a manufacturer frequently used by a user is set in advance as a default value, and when a user selects a position to place the implant, a model set to a default value is arranged in a determined position and direction.

The scale UI generation unit 23b generates and displays a scale UI capable of adjusting the width and length of the fixture. The scale UI generation unit 23b generates a scale UI by using the scale UI generated by the scale generation unit 23, The scale UI is generated so that the scale is displayed corresponding to the width and length information.

The scale UI includes a width scale UI displayed on a horizontal axis on the width direction where the width of the fixture can be adjusted and a length scale UI displayed on a vertical axis on the length direction where the length of the fixture can be adjusted. Also, the scale UI has a control point so that the user can click the point to adjust the width or length.

Fixture products are classified by manufacturer, and even the same manufacturer is divided into product groups. Generally, products are classified according to the surface treatment method. There are various products according to the length and width in the same product group.

The scale UI generator 23b according to the present invention generates and displays the length or width information of the other products belonging to the same product group as the fixture set by the user or the default value in the scale UI. In this manner, the scale UI generation unit 23b notifies the changeable length or width information in the same product group, so that the user can simply replace the fixture by simply clicking the desired scale. In the embodiment of the present invention, the scale UI generation unit 23b generates only the width and length information of the products belonging to the same product group. Generally, the product groups preferred or handled by the dentist or the user (doctor) , Reflecting the reality that only the dimensions are changed according to the patients in the product family.

The object modifying unit 50 modifies the position or size of the implant object, and moves, rotates, or resizes or changes the position of the object according to a user's operation command. When the scale corresponding to the size to be changed is selected in the scale UI, the object generation unit 40 changes the scale to be displayed corresponding to the scale and displays it. In addition, when a user selects a virtual crown and a fixture and issues a drag or rotate instruction, the position and direction of the virtual crown and the fixture are modified according to the instruction.

If the user wishes to change the fixture to another product family, they can also change the fixture's product line by selecting a product from another family in the Implant Library. At this time, the scale UI generation unit 23b generates and displays the width and length information of other products belonging to the changed fixture product group displayed on the screen, using a scale.

3 and 4 illustrate an example of an object creation and scale UI implementation screen according to the first embodiment of the present invention. For example, when the user selects the tooth number and the maximum wind and sweep position at the position where the implant is to be placed, the positioning unit 30 determines the size and position of the crown and the position of the fixture. And the scale UI generation unit 23b generates the scale width and length information of all the products belonging to the product group of the fixture as a scale UI, and displays it on the screen as shown in FIG. 3 (a).

3 (a) shows a screen in which a virtual crown, a fixture, and a scale UI are displayed together. The crown, fixture, and scale UI can be displayed sequentially or simultaneously. On the other hand, the virtual crown, the fixture, and the scale UI can be displayed in different colors in order to distinguish the user's implant objects. The rotational axis of the virtual crown and the rotational axis of the fixture are displayed to be coincident and can be modified by the user.

In FIG. 3A, the scale UI is displayed together with the fixture, and the scale of the scale UI and the dimension of the fixture correspond to each other. That is, since the height of the currently selected fixture is 6.5 mm and the width is 4 mm, it is displayed to correspond to the corresponding scale in the scale UI. In FIG. 3 (a), in the scale UI, four width scales are displayed on the left and right sides, and four scales on the length scale are displayed. In other words, it can be seen that there are two width dimensions and four length dimensions of the products in the same product family as the fixture on the current screen. 3 (a), the dimension is displayed next to the fixture, and the user can know at a glance that the height of the fixture displayed on the current screen is 6.5 mm and the width is 4 mm.

FIG. 3 (b) shows that a user creates and displays a control point when selecting a scale desired to change the size of the fixture in FIG. 3 (a). For example, if the user decides that the length of the fixture should be replaced with a larger one in the image, and selects a scale larger than the height of the current fixture in the length scale to change the height of the fixture to a larger size, A circular control point is generated and displayed. This allows the user to intuitively know the scale he or she chooses.

FIG. 3 (c) shows a screen executed after selecting a control point in FIG. 3 (b). When the user selects a length scale larger than the height 6.5 mm of the fixture in FIG. 3 (b), the fixture is changed to a product corresponding to the scale and displayed on the screen as shown in FIG. 3 (c). Then, the changed fixture dimensions are displayed on the screen as 8.5 mm and 4 mm, so that the user can immediately know the dimensions of the fixtures that the user has changed.

As such, the present invention intuitively shows the width and length information of other products belonging to the same product group as the currently selected fixture through the scale UI, so that the user can easily select an applicable fixture without measuring the depth or width of the position to be inserted So that the convenience of the user's correcting operation can be improved.

In the above-described embodiment, the user can select a plurality of consecutive teeth numbers in the tooth UI area of FIG. 2 and select a position to implant the implant. At this time, if the user selects a plurality of consecutive tooth numbers and selects both ends of the maximum outline of the position where the implant is to be placed in the multi-dimensional image of the patient, the position determining unit 30 determines the general tooth size The size and position of a plurality of consecutive virtual crowns are determined in consideration of the ratio, and similarly, the orientation and position of the corresponding fixture are determined. Here, the implant placement position may be selected by the user's input, but may also be selected by an automated algorithm.

The object generating unit 40 generates a virtual crown and a fixture according to the size and position of the virtual crown determined by the positioning unit 30, the orientation and position of the fixture, and displays the virtual crown and fixture at the corresponding position.

FIG. 5 illustrates an example of a screen of a plurality of dental implant simulations according to another embodiment of the present invention. 5 (a) shows that a user selects three tooth numbers to be implanted in the teeth UI and clicks on the multi-dimensional image of the patient at both ends where three teeth are located. 5 (a), it can be seen that three teeth UI corresponding to the tooth number selected in the teeth UI are displayed in different colors. In the multi-dimensional image of the patient, Represents one point and two points.

5 (b) shows a screen executed after the user selects three tooth numbers to be implanted in the tooth UI and clicks on the multi-dimensional image of the patient at both ends where the three teeth are located. Three virtual crowns and fixtures are created in the red B region and can be seen on the patient multi-dimensional image. The implant planning apparatus according to an embodiment of the present invention has data on a standard size ratio according to a tooth position (tooth number) in advance as data, and when the implant is applied to a continuous tooth, And determines the size of the virtual crown based on the size of the virtual crown.

As described above, according to the present invention, not only the number of implants to be placed but also the number of successive tooth areas can be automatically determined by displaying the size and position of the crown, the position of the fixture, and the orientation of the fixture.
