Description

Photographing method for patient based on application for taking picture for producing dental implant}

In the present invention, since it is illegal for a dental technician to face a patient directly for the purpose of making a dental prosthesis under the current medical law, a dental prosthesis must be manufactured based on the patient's inaccurate tooth photo information provided through a doctor. This is to solve a problem that frequently occurs cases of remanufacturing because the manufactured dental prosthesis is not suitable for the patient.

Based on the photographing application for making dental prosthesis presented in the present invention, a 3D image along with a pre-acquired oral scan image of the patient by accurately taking a picture of the patient's face and receiving the photographed image file through the cloud server It is provided in a tooth design program to provide a suitable dental prosthesis for each patient, and relates to a method of photographing a patient based on a photographing application for making a dental prosthesis.

In order to manufacture a dental prosthesis through a dental technician, accurate face shape information and tooth information about the patient are important. Based on the scanned image, the 3D image tooth design program has no choice but to produce a dental prosthesis.

In order to manufacture a dental prosthesis suitable for a patient, it is necessary to hold the vertical line and horizontal line based on the patient's face, but the requirements for this were not sufficiently satisfied, and thus, cases of manufacturing dental prosthesis based on inaccurate photographic information frequently occurred.

As a result, it was difficult to properly apply the originally manufactured dental prosthesis to the patient, resulting in a problem that had to be remanufactured.

In the conventional method of photographing a patient, the patient's face is photographed with the eyeball in the center, and then vertical lines and horizontal lines are drawn using a digital image editing program such as paint or photoshop, or a picture is taken with a thread or a thin string attached to the face. Became.

The method of photographing with the eyeball is difficult to grasp the exact vertical line and horizontal line required for manufacturing a dental prosthesis, and the method of attaching the thin strap makes it easier to shoot compared to the method of photographing with the eyeball, but an assistant is placed next to the patient. In addition, since the assistant has to take a method of photographing vertical and horizontal lines with a thread or a thin string on the patient's face, the patient's point of view was reluctant to put something on his or her face. There was a drawback of having at least two people.

As described above, there is a problem in that it is difficult to collect accurate information of a patient for manufacturing a dental prosthesis through the current medical method and the conventional imaging technique, and a dental prosthesis must be manufactured based on inaccurate information. Therefore, it is necessary to present a method to improve such problems.

The present invention provides the correct dental prosthesis optimized for each patient, thereby solving the problem of remanufacturing that frequently occurs after the initial dental prosthesis is manufactured, thereby eliminating the waste of human, material, and time resources, and It is intended to provide a method of photographing a patient based on a photographing application for manufacturing a dental prosthesis that can increase a sense of satisfaction by resolving distrust and discomfort in a patient's procedure.

[Step of focusing the patient's face (S10)]

When executing the photographing application 10 for manufacturing a dental prosthesis installed in the terminal 100, the initial screen inputs the patient's name, age, sex, and tooth information presented by the patient information input unit 101 of FIG. The window is activated.

When the patient's personal information and tooth information are input through the activated window, it is switched to the photographing mode and the patient can be photographed.

This step (S10) is an initial step for photographing the face of the patient through the photographing application 10 for manufacturing a dental prosthesis installed in the terminal 100, as shown in FIG. 3, and installed in the terminal 100 This is a step in which the eyes, nose and mouth of the patient are recognized and focused by interlocking with the existing face recognition sensor.

[Step of the photographer adjusting the shooting angle and position (S20)]

In this step (S20), as shown in FIGS. 4 and 5, the lateral guide line 121 and the longitudinal guide line 122 are expressed based on the eyes, nose, and mouth of the focused patient's face, This is a step in which the photographer adjusts the photographing angle and position until the color of the guide lines 121 and 122 is changed from red to green.

In the photographing application for producing a dental prosthesis, a guide line generation unit 102 is configured, and each position of the patient's eyes, nose, and teeth visible through the photographing screen through the guide line generation unit 102 is installed in the terminal. It is detected through a face recognition sensor, and generates a lateral guide line 121 suitable for each position of the eyes, nose, and teeth, and a longitudinal guide line 122 based on the center of the tip of the nose.

At this time, when the transverse guide line 121 and the longitudinal guide line 122 exceed the possible distance between the eyes, nose, and teeth in the oral cavity, the guide lines 121 and 122 are displayed in red. do. Conversely, when the distance is within the possible range, the red color is changed to green.

That is, in the case of the transverse guide line 121, when the first guide line 121a in the transverse direction generated based on the iris and the iris of both eyes is out of the iris region, it is displayed in red, and then enters into the iris region. When it is, the color changes to green.

In the case of the nose, when the transverse second guide line 121b generated based on both nostrils is out of the nostril area, it is displayed in red, and when it enters the area, the color is changed to green.

In addition, a third guide line 121c in the transverse direction is generated based on a point where the upper and lower jaws meet, and when it is out of the point, it is displayed in red, and when it reaches the point, the color is changed to green.

In addition, in the case of the longitudinal guide line 122, an error range is set in both directions from the center of the nose based on the center of the nose, and when it is out of the error range, it is displayed in red, and when it falls within the error range, The red color changes to green.

Accordingly, the photographer can easily determine whether the patient's photographing direction and angle are correct by confirming that both the transverse guide line 121 and the longitudinal guide line 122 are displayed in green. In addition, through this, the photographer can take an accurate picture by changing the photographing position and angle little by little so that both the horizontal guide line 121 and the vertical guide line 122 can be changed to green.

Colors of the guide lines 121 and 122 are controlled through the photographing guide unit 103 shown in FIG. 2. That is, when the patient's face is not facing the front or is inclined to the left and right and is unsuitable for photographing a dental prosthesis, the transverse and longitudinal guide lines 121 and 122 are red. Display and, if appropriate, green.

[Shooting step (S30)]

This step (S30) is taken in a state where the lips are open so that the patient's teeth can be clearly exposed to the outside in a situation in which both the guide lines 121 and 122 are identified in green, as shown in FIG. 6. It is a step to do.

[Photographed tooth removal step (S40)]

This step (S40) is a step of editing the image captured in the photographing step (S30), as shown in FIG. 7. That is, in the above step, when the tooth part in the photographed image is double-clicked (FIG. 7(a)), a dotted line is displayed along the inner edge of the lips and the area to be deleted is displayed (FIG. 7(b)). Four size control boxes including the area are displayed while drawing a rectangular area, and the photographer properly adjusts the area through the size control box when the area needs to be adjusted.

After the adjustment is complete, if the tooth part is clicked, the tooth part is deleted. (Fig. 7(c)) This deletion process is performed through the image editing unit 105 included in the application 10. The image editing unit 105 is composed of an image editing program.

[Temporary photographed image creation step (S50)] / [New tooth image selection check step (S60)]

As shown in FIG. 8, the step S50 is a step of importing a tooth image to be replaced from the image in which the patient's existing teeth have been deleted through the step S40 and applying it to the patient's face.

When the patient's existing tooth is pressed for 2 to 3 seconds, the tooth image gallery unit 104 in which the newly applied tooth image is stored is activated, and various types of teeth that can be selected according to the shape of the patient's face The image is presented.

The face shape is determined by the ratio of the width x of the face measured through a point connecting both sides of the cheekbones of the face, and the length y connecting the central portion of the nose of the face to the tip of the head and the tip of the lower part of the face.

In other words, when the value of y/x is measured and exceeds the set average value of 1.4, that is, the larger the y value, the longer the length of the tooth and the angled tooth at the bottom of the tooth is displayed in a list.

If the average value is less than 1.4, that is, the larger the x value is, the shorter the length of the tooth and the rounded shape is, and the teeth with rounded corners are also displayed in a list.

The tooth image generator 106 serves to provide a tooth image to be replaced according to the shape of the patient's face, and the width x of the face measured through a line connecting points connecting both sides of the cheekbones of the face, and the width of the face A tooth image to be replaced is provided by dividing the face length into a long shape and a round shape through a ratio (y/x) of the length y that connects the tip of the head to the tip of the chin to the upper part of the nose and the tip of the chin to the lower part.

When the ratio (y/x) exceeds 1.4, the face is recognized as a long shape, and when the ratio (y/x) is less than 1.4, the face is recognized as a round shape, and a tooth image to be replaced is provided.

In more detail, the tooth image generator 106 includes a face width x measured through a line connecting points connecting both sides of the cheekbones of the face, and the head end and the lower part toward the upper part of the central part of the nose of the face. The furnace provides an image of a tooth to be replaced newly by dividing it into a long shape and a round shape through the ratio of the length y (y/x) to the tip of the chin.

In the case of the shape having a long face, a tooth image having a long tooth length and an angled lower edge of the tooth is provided,

In the case of the rounded face, a tooth image having a short tooth length and a rounded lower edge of the tooth is provided.

More specifically,

In the case of the shape of the long face,

The central incisor has a width/length of 8.4 mm / 10.2 mm with a ratio of 0.82,

Lateral incisors have a horizontal/vertical length of 6.8 mm / 9.6 mm, with a ratio of 0.70 and

The canine provides a tooth image with a ratio of 0.76 with a horizontal/vertical length of 7.6 mm / 10.0 mm,

In the case of the round shape of the face,

The central incisor has a width/length of 8.4 mm / 10.6 mm with a ratio of 0.77,

Lateral incisors have a horizontal/vertical length of 6.8 mm / 10.0 mm, with a ratio of 0.68 and

The canine provides a tooth image with a ratio of 0.72 with a width/length of 7.6 mm / 10.5 mm.

In addition, in the corner angle, the tooth image forms a round by cutting a corner by a predetermined length in the horizontal and vertical directions from the intersection point where the vertical line descending along the outer line of the tooth and the horizontal line of the base line of the tooth meet each other. ,

In the case of the long face,

Central incisor 2.2 mm wide, 2.0 mm long,

Lateral incisors 2.8 mm in width, 1.5 mm in height,

Provides a tooth image that forms a round by cutting the corners of the canine by 3.3 mm in width and 4.5 mm in length,

In the case of the round shape of the face,

Central incisor width 2.0 mm, length 2.0 mm,

Lateral incisors 2.5 mm wide, 1.5 mm long,

It provides a tooth image that forms a round by cutting the corners of the canine by 3.3 mm in width and 4.5 mm in length.

Through such a selection process, one of the list teeth displayed through the tooth image gallery unit 104 is selected and applied to the patient through the tooth image generating unit 106.

The tooth image newly applied to the patient's mouth as described above is to allow the patient to select a tooth preferred by the patient by directly confirming the image when the dental prosthesis is manufactured and applied to the patient.

That is, when the patient does not like the tooth image newly applied to the patient's mouth by using the tooth image generator 106, the patient requests replacement of another tooth image, so that various tooth images can be applied to select the optimal tooth image. .(S60)

That is, through the tooth image gallery unit 104, a tooth image recommended according to the shape of the face may be selected as it is, but another tooth image may be applied according to a patient's request.

[Cloud server transmission step (S70)]

In this step (S70), as shown in FIG. 9, after confirming whether or not the newly applied tooth image is finally selected through the patient, if there is approval from the patient, a final image file is generated and transmitted to the cloud server. .

In the case of approval from the patient, a final image file is generated through storage, and the final image file is displayed together with patient information input through the patient information input unit 101. In addition, the final image file is stored in the database unit 106.

When the final image file is created, the photo transfer button is activated, and when the photo transfer button is clicked, the file stored in the database unit 106 is loaded, selects the file, and then clicks the photo transfer button again. If so, the final image file is finally transmitted to the cloud server.

The correct dental prosthesis production photography app according to the present invention and a photo generation method using the same can provide accurate information for producing the correct dental prosthesis even if the dental technician does not face-to-face with the patient and collects the correct dental prosthesis suitable for the patient. Prostheses can be provided, and dental technicians can eliminate the problem of remanufacturing by revising the primary fabrication, which has great industrial applicability.
