Description

Method and device for designing a dental prosthesis using an electronic chart

The present invention relates to a method and apparatus for designing a dental prosthesis. More specifically, it relates to a method and apparatus for automatically generating design data of a prosthesis by linking an electronic chart including prosthesis data and a dental prosthesis design module, without a user's individual input for design elements of the prosthesis.

As digital dentistry is introduced in the dental treatment field, an electronic chart including personal information of a patient and treatment information of a patient is being used. In addition, a design module for designing a device required in a dental treatment process is also being used. For example, there is a module for designing an orthodontic device, a module for designing a dental prosthesis, and the like.

However, in the prior art, since the electronic chart and the design module are separated, it is difficult for users to use them. More specifically, since the design module essentially requires the user's input for the design element of the prosthesis, unnecessary errors, cost loss, and time loss occur in inputting the design element.

Furthermore, the prior art has a problem in that, depending on the knowledge of the user who designs the prosthesis, the quality of the finished prosthesis designed by the user varies.

In an embodiment, by displaying the prosthesis design correction data, the user may more effectively recognize the modified prosthesis design data. Furthermore, it is possible to design a dental prosthesis more optimized for the patient. However, the present invention is not limited to the example described above, and any configuration capable of adjusting the increase or decrease of a design element by a UI capable of adjusting the increase or decrease may be included in the present invention.

In an embodiment, a UI for modifying design data may be displayed on the image. More specifically, according to an embodiment, a button for selecting any one of the groups may be displayed by grouping the design elements into a plurality of groups selectable by the user. Here, in response to a user input selecting a button, a design element may be modified. In addition, design correction data corresponding to a user's input of selecting one of the plurality of groups may be displayed in advance before the user's input. In an embodiment, when it is determined that the user's input for correcting the design data has occurred, the design correction data may be displayed in response to the user's input. Hereinafter, it will be described with a specific example.

Referring to FIG. 14 , a diagram embodied in the inset image 42 described with reference to FIG. 5 is shown. Here, data may be grouped by insertion, which is a design element, into the adjacent tooth interference minimization group 91 and the abutment undercut minimization group 93 . In this case, images 91a and 93a representing the grouped design elements may be displayed. The design correction data 91a corresponding to the neighbor interference amount minimization group may be displayed in advance before the user's input. In addition, the design correction data 93a corresponding to the abutment undercut minimization group may be displayed in advance before the user's input.

As a specific example, a user who wants to design an insertion path for a prosthesis by minimizing the amount of interference with adjacent teeth may select the button of the minimize interference amount of adjacent teeth group 91 . In addition, a user who wants to design an insertion path for a prosthesis by minimizing the undercut of the abutment may select the button for minimizing the undercut of the abutment group 93 . According to an input of a user who has selected the button, data may be modified through insertion, which is a design element, and design data reflecting this may be generated.

The dental prosthesis design method using the electronic chart according to an embodiment of the present invention described with reference to FIG. 14 includes a UI for correcting the generated prosthesis design data, so that a dental prosthesis optimized for a patient can be designed. By grouping the design elements into a plurality of groups selectable by the user and displaying a button for selecting any one of the groups, the user can modify the design elements.

For example, in the case of a design element requiring correction of a plurality of variables to correct a design element, a plurality of groups frequently used for modifying the design element may be preset, and any one of the plurality of groups may be selected in advance. The prosthesis design data may be modified in response to a selection input by the user. For example, as described above, in order to correct data by insertion, which is a design element, a design of a prosthesis that minimizes an adjacent tooth and an interference amount may be preset and grouped. In order to correct the data with insertion, which is a design element, the design of the prosthesis that minimizes the undercut of the abutment may be preset and grouped.

For another example, even if a design element requires modification of one variable in order to modify a design element, a plurality of groups frequently used for modifying the design element may be preset, and any one of the plurality of groups may be preset. The prosthesis design data may be modified in response to a selection input by the user. For example, as described above, in order to correct contact data, which is a design element, a design of a prosthesis that minimizes adjacent teeth and a contact surface may be preset and grouped. In order to correct the contact data, which is a design element, the design of the prosthesis maximizing the adjacent teeth and the contact surface may be preset and grouped.

According to this example, the user can design a dental prosthesis optimized for the patient's teeth by selecting any one of a plurality of groups frequently used for modification of design elements without complicated manipulation to revise the dental prosthesis design data. .
