Abstract
Disclosed is a method of manufacturing a guide stent of a dental implant. The method includes a first step of obtaining a three-dimensional image of periodontal tissue in a mouth of a patient through an CT scan and a three-dimensional exterior image corresponding to the three-dimensional image through an oral scan; a second step of matching the three-dimensional image and the three-dimensional exterior image through a difference amp which overlaps the three-dimensional image and the three-dimensional exterior image and outputs a matching degree between the images, and obtaining a three-dimensional procedure guide image; and a third step of manufacturing a stent body having a through hole corresponding to a preset implant implantation position according to the obtained three-dimensional procedure guide image.
