Method and device for providing expected error information related to implant placement

A device for providing expected error information related to implant placement, the device comprising:

• a processor configured to:
• obtain first intraoral data on the basis of imaging or scanning an oral cavity;
• obtain a guide wearing simulation model for simulating a state in which a guide template model obtained on the basis of the first intraoral data is applied to the intraoral data;
• obtain second intraoral data on the basis of imaging or scanning performed while a guide template corresponding to the guide template model is worn on the oral cavity;
• obtain a fiducial marker wearing scan model indicating a state in which the guide template is worn on the oral cavity on the basis of the second intraoral data;
• and
• provide expected error information regarding a position of an implant model by using a first fiducial marker model coupled to the guide wearing simulation model and a second fiducial marker model coupled to the fiducial marker wearing scan model.

A computer-readable, non-transitory recording medium having stored thereon a program which, when executed by a computer system, causes the computer system to implement a method for providing expected error information related to implant placement, wherein the method comprises the steps of:

• obtaining first intraoral data on the basis of imaging or scanning an oral cavity;
• obtaining a guide wearing simulation model for simulating a state in which a guide template model obtained on the basis of the first intraoral data is applied to the intraoral data;
• obtaining second intraoral data on the basis of imaging or scanning performed while a guide template corresponding to the guide template model is worn on the oral cavity;
• obtaining a fiducial marker wearing scan model indicating a state in which the guide template is worn on the oral cavity on the basis of the second intraoral data;
• and
• providing expected error information regarding a position of an implant model by using a first fiducial marker model in which a fiducial marker is coupled to the guide wearing simulation model and a second fiducial marker model corresponding to the fiducial marker wearing scan model.
