Abstract

Claims (44)

1 . A method of providing information for dental treatment, the method comprising:

acquiring a first scan model by scanning a target object;

acquiring a design model that is generated based on a first scan model and is a model for an artifact to be attached to the target object;

after the artifact has been manufactured based on the design model, acquiring a second scan model generated by scanning the artifact;

aligning the first scan model and the second scan model based on a margin line corresponding to a coupling boundary between the target object and the artifact;

identifying a part of the second scan model corresponding to an incorrectly-made part of the artifact, based on a result of the alignment; and

displaying guide information for guiding correction of the incorrectly-made part of the artifact, based on information about the identified part.

2 . The method of claim 1 , wherein the aligning includes aligning the first scan model coupled to the design model, and the second scan model.

3 . The method of claim 1 , wherein

the target object is a tooth or an abutment of an implant,

the artifact is a crown.

4 . The method of claim 3 , wherein the aligning includes aligning the first scan model coupled to the design model and the second scan model, based on a first line corresponding to the margin line of the target object in the design model and a second line corresponding to the margin line of the target object in the second scan model.

5 . The method of claim 1 , wherein the identifying the part of the second scan model includes:

based on the result of the alignment, identifying the part of the second scan model which collides with at least one of: the target object; and at least one tooth adjacent to the target object.

6 . The method of claim 5 , further comprising:

classifying degrees of collision of the second scan model with at least one of the target object and at least one tooth adjacent to the target object into a plurality of levels, and generating information such that the plurality of classified levels are differently displayed by using at least one of different colors, transparencies, patterns, symbols, figures, and texts.

7 . The method of claim 1 , further comprising outputting a user interface screen including the information about the identified part and the guide information.

8 . The method of claim 1 , wherein the information about the identified part includes information on at least one of a thickness, a length, an area, and a volume of the identified part.

9 . The method of claim 1 , wherein the artifact is one of a crown, an inlay, and an onlay.

10 . The method of claim 1 , wherein the acquiring of the design model includes acquiring a design model obtained by three-dimensionally modeling the artifact to be attached to the target object, through a computer aided design (CAD) based on the first scan model.

11 . The method of claim 10 , wherein the aligning includes

comparing an entire shape of the design model coupled to the first scan model with an entire shape of the second scan model, and first-aligning the design model and the second scan model, and

second-aligning the design model and the second scan model, which are first-aligned, based on margin information.

12 . An electronic device that provides information for dental treatment, the electronic device comprising:

a communication interface configured to receive data from an external device; and

a processor configured to execute at least one instruction to generate information for dental treatment,

wherein the processor

acquires a first scan model by scanning a target object,

acquires a design model that is generated based on a first scan model and indicates an artifact to be attached to the target object,

after the artifact has been manufactured based on the design model, acquires a second scan model generated by scanning the artifact,

aligns the first scan model and the second scan model based on a margin line corresponding to a coupling boundary between the target object and the artifact,

identifies a part of the second scan model corresponding to an incorrectly-made part of the artifact, based on a result of the alignment, and

displays guide information for guiding correction of the incorrectly-made part of the artifact, based on information about the identified part.

13 . The electronic device of claim 12 , wherein the processor aligns the first scan model coupled to the design model and the second scan model, based on the margin line.

14 . The electronic device of claim 12 ,

further comprising a display,

wherein the processor controls the display to output a user interface screen including the information about the identified part and the guide information.

15 . A non-transitory computer-readable recording medium on which one or more programs are recorded, the computer-readable recording medium comprising instructions for performing a method of providing information for dental treatment, the method including:

acquiring a first scan model by scanning a target object;

acquiring a design model that is generated based on a first scan model and is a model for an artifact to be attached to the target object;

after the artifact has been manufactured based on the design model, acquiring a second scan model generated by scanning the artifact;

aligning the first scan model and the second scan model based on a margin line corresponding to a coupling boundary between the target object and the artifact;

identifying a part of the second scan model corresponding to an incorrectly-made part of the artifact, based on a result of the alignment; and

displaying guide information for guiding correction of the incorrectly-made part of the artifact, based on information about the identified part.
