Method of implanting dental restoration

A method of implanting dental restoration, comprising:

• generating a three-dimensional planning image in a first operation in which a scanning image including three-dimensional exterior information of upper and lower jaws, of which at least one is a restoration target gum part, overlaps and matches to a computed tomography (CT) image, a plurality of pieces of implantation information of implants are set along a dental arch in the three-dimensional planning image, and an implanting guide device including a bone reduction guide configured to guide flattening of an alveolar bone and a surgical guide configured to guide implantation of the implants is designed and manufactured;
• flattening the alveolar bone in a second operation by being guided by the implanting guide device, the implants are implanted, and holder devices, which include holder abutments and a fixing bar fixed to through-insertion portions of the holder abutments, are fixed to upper sides of the implants;
• correcting a temporary denture in a third operation to be occluded between the upper and lower jaws to form a temporary mounting portion, into which the holder device is inserted, in an inner surface portion of the temporary denture softened to be deformed due to an occlusal pressure to correspond to an occlusal vertical dimension of a patient when heated with a temperature within a preset softening temperature range;
• obtaining a corrected scanning image corrected to expose three-dimensional exterior information of the temporary mounting portion to an outside in a fourth operation from a scanning image of the temporary denture, and the three-dimensional exterior information of the temporary mounting portion is replaced and swapped with a virtual holder device;
• and
• forming a mount part in a fifth operation in an inner surface portion of an artificial gum part on the basis of the virtual holder device, and an artificial tooth part is fixed to the artificial gum part to which a clip engaged with the fixing bar is fixed to manufacture a dental restoration,
• wherein the first operation includes:
• virtually disposing a virtual implant selected from a digital library on the basis of the CT image to correspond to the implantation information, and
• virtually and concentrically disposing a virtual implanting guide sleeve to be spaced upward from an upper end portion of the virtual implant by an offset distance, wherein the virtual implanting guide sleeve and the scanning image overlap and are integrally stored;
• and
• generating design information of the surgical guide, wherein a virtual coupling hole corresponding to an outer circumference of the virtual implanting guide sleeve is formed in the design information.
