Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an implant planning apparatus according to an embodiment of the present invention. 1, an implant planning apparatus 100 according to an embodiment of the present invention includes an image generating unit 10, a user interface unit 20, an object generating unit 30, a standard library 40, (50), a product library (60), and an object control UI generation unit (70).

The image generating unit 10 generates a tooth array image or a tooth array model of a patient for implant planning.

The image generating unit 10 generates a two-dimensional or three-dimensional multi-dimensional image model in which a patient's tooth arrangement appears based on image data acquired through a photographing apparatus such as X-ray, CBCT, MRI, or oral scanner. Such an image model can be generated through image processing such as image reconstruction, registration, and segmentation.

Based on the image thus generated, a simulation is performed to virtually place the implant by determining the placement position, the placement direction, the placement angle, the length, and the size of the implant object constituting the implant such as a fixture, a crown, and an abutment do.

The user interface unit 20 receives necessary information from a user and displays information. The user interface unit 20 includes input means for inputting information such as a mouse, a keyboard, a button, and a keypad, an input menu and a processing result, Display means for displaying information, a touch screen for providing input and output through a single device, and the like.

The object generating unit 30 generates an implant virtual object model corresponding to the missing tooth. The virtual object model corresponding to the lost tooth can be determined by user input or by an automated algorithm and is based on the criterion for determining the attribute of the implant object such as the size, It can also be placed directly on the image by selecting it directly from the implant object list. The position, direction, angle, etc. of the implant object may be determined based on a previously set placement criterion considering the distance to the adjacent tooth, the location of the neural tube, and the like.

The standard library 40 stores a virtual object model corresponding to each tooth based on age, sex, and standardized teeth information for each tooth, and provides an implant virtual object model corresponding to the missing teeth requested from the object creating unit 30 do.

The product information providing unit 50 determines products having the highest degree of similarity to the specifications of the implants planned by the practitioner, and provides information on the determined implant product models. That is, a product having a high degree of similarity is determined in consideration of the characteristics of the implant closest to the planned virtual object, for example, the length, width, material, and frequency of use of the practitioner, and information on the determined implant product model is provided. For reference, information on the implant product model may include the attributes of the product model, such as the name of the implant product model, the length, width, material, diameter, shape type, and surface treatment method of the product model. A 3D image corresponding to the corresponding model, text information, and the like.

For example, when the length of a fixture is designated as a feature having the highest priority, the product information providing unit 50 determines a product having the same fixture length among the planned implant specifications The product with the highest degree of similarity is determined. At this time, if products having the same length are present, the second order of priority is compared to select a product having a higher degree of similarity. Priorities are assigned to characteristics such as diameter, material, material, preferred brand product of the practitioner, and frequency of use of the practitioner, and sequentially compared to determine the most similar product based on the priority.

In addition to the method of determining the similarity according to the priority, various implant standard characteristics are set as variables, and the minimum distance based on the Euclidean distance between the characteristic parameter value of the optimization model and the product standard is calculated, The degree of similarity can be evaluated in such a manner that a weight is given and an average value is obtained.

It is preferable that the priority and the degree of similarity determination are provided by default and that the flexibility of the implant planning is provided by arbitrarily selecting and changing by the user.

The product library 60 stores implant models classified by company, type, size, and material, and provides product information necessary for the product information providing unit 50 to determine the degree of similarity.

The object control UI generation unit 70 generates a spherical object control UI when a predetermined event occurs. That is, when a predetermined specific event occurs such as the operator selecting a specific icon, inputting a command shortcut key, or pressing a right button of a mouse, it is possible to adjust the size, position and orientation angle of the implant virtual object Creates and displays an object control UI.

FIG. 2 is a tooth array image in which a spherical object control UI according to an embodiment of the present invention is displayed.

2, the spherical object control UI includes a vertical center line a, a horizontal center line b, a tilt adjustment line c, a length increase button LB1, a length decrease button LB2, a width increase button WB1, The width decreasing button WB2 and the intersection of the vertical center line a and the horizontal center line b as the center of the sphere.

The vertical center line a is located on the longitudinal center axis of the object model and the horizontal center line b is formed perpendicularly to the center line a and the center O of the object model, And is formed in the longitudinal direction and the vertical direction.

The tilt adjustment line c is formed by a slant line passing through the center O of the sphere which is the intersection of the vertical center line a and the lateral center line b and one end of which is located on the surface of the sphere. The tilt adjusting line (c) is for adjusting the setting angle of the object model. When the tilt adjusting button (c1) provided at the intersection located on the surface of the sphere is rotated along the sphere surface, Allow the angle to be adjusted.

The length increase button LB1 and the length decrease button LB2 are formed at two intersections where the vertical center line a and the spherical surface meet. An increase button LB1 is provided at the intersection of the upper end and a decrease button LB2 is provided at the intersection of the lower end. Respectively.

The width increasing button WB1 and the width decreasing button WB2 are formed at two intersection points where the horizontal center line b and the spherical surface meet and the increase button W1 at the right intersection point and the decrease button W2 at the left intersection point .

As the length increase button LB1, the length decrease button LB2, the width increase button WB1, and the width decrease button WB2 formed at both ends of the vertical center line a and the horizontal center line b are pressed, As the length and width of the object model increase or decrease according to the corresponding scale, the direction and fine adjustment can be performed when adjusting the length of the mouse drag control. That is, when the displacement of the object model is set to 0.1 mm by pressing the length and width increase button (LB1, WB1) once, the size can be finely adjusted in increments of 0.1 mm according to the operator's one button selection.

If a length increase button LB1, a length decrease button LB2, a width increase button WB1 and a width decrease button WB2 are selected in a state in which a product having a high degree of similarity is determined and displayed, The next small product can be selected and displayed. That is, when a length increase button LB is pressed on the basis of a fixture having a length of 12 mm, a product having a width larger than 12 mm and having the smallest increase width is displayed. Therefore, if the next longer product is a 13mm fixture, it can be replaced by a 13mm fixture, and if a 12.5mm fixture is available, it can be replaced by 12.5mm. In other words, the length increase button LB1, the length decrease button LB2, the width increase button WB1, and the width decrease button WB2 not only increase or decrease the size of the virtual implant object according to a predetermined scale, After being marked as a product, it shall be mixed and used so as to be replaced with a product of adjacent size.

On the other hand, the length and width of the fixture are closely related to the size of the crown. For example, if the width of the fixture is too small compared to the crown size, the crown may be broken because it can not sufficiently support the force applied between the fixture and the crown. Accordingly, when the length or width of the fixture is changed using the buttons LB1, LB2, WB1, and WB2 as described above, the size of the crown may be automatically changed corresponding to the length or width of the fixture. It is a schematic representation of the change in object model with reduced length and width by pressing the length and width reduction buttons.

Referring to FIG. 3A, when a virtual implant object 301 indicated by a solid line is provided to the practitioner, the practitioner presses the lower length reduction button LB2 of the object control UI to reduce the length by a predetermined length. The image is provided to the practitioner in a state that the length is shortened like the virtual implant object 301 'indicated by a dotted line, and the practitioner can increase the number of times of pushing the length decreasing button LB2 to further shorten the desired length have. 3B, when the virtual implant object 302 indicated by the solid line is displayed, the practitioner presses the left width reduction button WB2 of the object control UI to reduce the width of the object by a predetermined width. An implant object having a reduced width such as a virtual implant object 302 'indicated by a dotted line is provided to the practitioner.

FIGS. 4A through 4D illustrate a method of adjusting the angle of insertion by manipulating the tilt adjusting line according to an embodiment of the present invention.

4A shows a case where the center O of the sphere of the spherical object control UI is located at the lower end of the object model 401. Fig. Since the tilt adjustment line (c) rotates the object model (401) with the center of the sphere (O) as its rotation axis during rotation, the operator can control the spherical object control UI on the longitudinal axis of the implant It is possible to arbitrarily select the pivot shaft by sliding in a parallel direction.

FIG. 4B is a view showing an implant object model (FIG. 4B) centered on the lower end of the object model when the operator rotates the tilt adjusting button c1 in a clockwise direction on a two-dimensional plane composed of a vertical center line a and a horizontal center line b 401 are rotated. When the practitioner wishes to rotate the implant object model 401 in the three-dimensional direction in a three-dimensional arbitrary direction, that is, outside the two-dimensional plane composed of the vertical center line (a) and the horizontal center line (b) It is possible to move the tilt adjusting button c1 in a desired direction and adjust the tilt adjusting button c1 so as to rotate in accordance with the displacement.

4B shows an example in which the tilt adjusting line c is generated at a position inclined by a certain angle with respect to the longitudinal center line a. However, the position of the tilt adjusting line c is not limited to this, It can be created at various locations if it is on the surface and past the center of the sphere (O). For example, the tilt adjusting line c may be generated so as to be located on the vertical center line a. By using the tilt adjusting button c1 thus generated, the operator can intuitively operate the setting angle.

FIG. 4C shows a case where the center O of the sphere of the spherical object control UI is slid in the longitudinal axis of the implant so that the center of the object model 402 is set as the rotational axis, unlike FIG. 4A.

The practitioner can control the amount of the set angle rotation by moving the center of the sphere (O) of the object control UI. The amount of implant angular rotation is reduced as the center (O) of the object control UI is moved from the lower end to the upper end of the longitudinal axis of the implant (shown by dot-dash lines). For example, when the center O of the object control UI is positioned at the lower end of the object model 401 as shown in FIG. 4A, the practitioner can largely adjust the placement angle, and the center of the object control UI (O) is moved to the upper end of the object model 402, the setting angle can be adjusted to be small.

Accordingly, the practitioner can designate an arbitrary position on the axis of the implant in the longitudinal axis (dash-dotted line) of the implant in consideration of the desired implantation angle, thereby enabling fine adjustment of the implantation angle for designating the optimum implantation position.

4D shows a case where the practitioner rotates the tilting button c1 in the clockwise direction within the plane of the two-dimensional plane constituted by the vertical center line a and the horizontal center line b while placing the pivot axis at the center of the implant object model 402 The implant object model 402 is rotated by the displacement of the tilt adjustment button c1 to change the implantation angle. As in Fig. 4B, the operation and position change of the tilt adjustment button c1 for the three-dimensional rotation can be equally applied.

As described above, by rotating the tilt adjustment line intersection c1 on the surface of the sphere with respect to each of Figs. 4A and 4C along the surface of the sphere, as shown in Figs. 4B and 4D, We can see that the object model revolves around the central axis O.

That is, FIGS. 4A to 4D illustrate a case where the operator manipulates the spherical object control UI in the longitudinal direction along the longitudinal center axis of the object model (shown by dash-and-dot lines) .

FIG. 5 illustrates a UI for providing numerical information of an object model size using a spherical object control UI according to an embodiment of the present invention.

Referring to FIG. 5, a numerical value in the length and width direction of a current virtual object model, which is a result of manipulation by a user, can be checked in units of mm from the initially provided implant virtual object model. Here, the initially provided implant virtual object model can be determined by the object generating unit 30 based on a placement criterion previously provided in consideration of the user's input, the distance from the adjacent tooth, the position of the neural tube, and the like. The length and width information of the manipulated virtual object model are in the form of a coordinate system in which the vertical center line and the horizontal center line are two axes, and numerical values in the length and width directions are displayed in coordinates according to a predetermined scale. The change in the numerical value can be confirmed.

6 is a flowchart illustrating an implant planning method according to another embodiment of the present invention. Referring to FIG. 6, the operation of the implant planning apparatus according to an embodiment of the present invention shown in FIG. 1 will be described in detail.

First, the image generating unit 10 generates a multidimensional image related to a tooth arrangement of the patient according to a selection of a practitioner input through the user interface unit 20 (S10).

In the image related to the tooth arrangement of the patient, the image generating unit 10 can select and display the placement position corresponding to the lost tooth by the operator's input through the user interface unit 20, The user can automatically select the placement position (S20).

Based on the selected placement position information, the object generation unit 30 acquires and provides an image of the standardized implant virtual object model based on the patient's age, sex, missing tooth number, race, etc. from the standard library 40, The generation unit 10 superimposes the image of the virtual object model on the tooth array image and displays it (S30).

When a predetermined event such as an input of a practitioner is generated through the user interface unit 20, the spherical object control UI generating unit 70 generates and displays a spherical object control UI (S40). At this time, the spherical object control UI can be displayed on the longitudinal center axis of the object model as shown in FIGS. 2 to 5, and can also be changed in position by sliding in the longitudinal direction. In addition, when the operation of the operator is interrupted, the center axis and the vertical center line may be moved to different positions so as to maintain parallelism. As described above, the display position of the spherical object control UI is not limited to a specific position.

Next, when the increase / decrease button of the object control UI is clicked through the user interface unit 20, the image generating unit 10 provides an image in which the length, the width and the placement angle of the implant object model are adjusted so that the practitioner can simulate (S50).

In step S60, the operator adjusts the size, placement position, and angle of the implant until the implantation plan is optimized for the patient through the user interface unit 20.

When all the treatment plans are established, the product information providing unit 50 determines products having the highest similarity to the established implant virtual object model and recommends them to the practitioner (S70). There are various methods for determining the degree of similarity based on certain criteria. A method of comparing the highest priority specification among the specifications of each product to which the priority is given from the product library 60 storing information about the implant product on the market and comparing the specifications having the priority order of the next rank The product with the highest degree of similarity can be selected.

In the embodiment of the present invention, the degree of similarity is measured by assigning priorities to product specifications in the order of length, diameter, frequency of use of the practitioner, material, and width. The frequency of use of the practitioner is determined based on the frequency of use by the same practitioner for each product or statistical data on the frequency of use of each product based on the same suppliers.

If the information on the recommended product is provided to the practitioner in the form of a text or image, the practitioner can confirm the recommended product through the user interface unit 20 (S80). If it is determined that the product having a high degree of similarity is not suitable for the implant treatment plan, the object generating unit 30 may reorganize the implant object model for re-planning or change the product recommended by the product information providing unit 50 (S90).

If a product suitable for the finally established implant treatment plan is selected, the image generating unit 10 displays the selected implant product on the simulation image so that the practitioner can directly confirm it with the naked eye and store all information (S100).
