Abstract: In order to improve manufacturing convenience and precision, the present invention provides a digital denture manufacturing method comprising: a first step of acquiring a three-dimensional work image, on which occlusion information between a target dental arch and an opposing dental arch and implant information of a fixture implanted in the target dental arch are displayed, and preparing a temporary denture in which a binding region formed to correspond to a binding portion profile of an abutment fastened to the fixture is arrayed and arranged; a second step of acquiring an auxiliary scan image for the temporary denture; a third step of acquiring, from the auxiliary scan image, a correction surface image on three-dimensional surface information of an inner surface-side engagement groove of the temporary denture including the binding region; and a fourth step of designing and manufacturing a digital denture having a virtual binding groove corresponding to the position and the shape of the three-dimensional sur

Abstract: The present invention provides a digital dental prosthesis manufacturing method including a first step in which a three-dimensional work image is acquired, the three-dimensional work image including surface information on an inner side of an oral cavity and a target dental arch in which fixtures are placed and occlusion information between the target dental arch and an opposing dental arch; a second step in which a temporary digital dental prosthesis is designed and manufactured; a third step in which the manufactured temporary digital dental prosthesis is installed on the target dental arch; and a fourth step in which a virtual coupling groove, which corresponds to surface information on the corrected coupling region, is set in an inner surface profile, which is set according to surface information on the corrected temporary shape-matching surface that is included in the corrected scan image, and a final digital dental prosthesis is designed and manufactured.

Abstract: The present invention provides a dental restoration manufacturing method for improving the precision and reliability of a dental restoration, the dental restoration manufacturing method comprising: a first step for acquiring, through an imaging device, each of a scanning image of a part where implantation is to take place and a corresponding antagonistic part, before the mounting of a coupling bite disposed between the part where implantation is to take place and the corresponding antagonistic part, and after the mounting of the inner and outer surface portions of the coupling bite in consideration of a vertical dimension of a patient by occlusal pressure, a CT image of the oral cavity occluded by means of the coupling bite, and a gothic arch motion image of a three-dimensional motion trajectory of the temporomandibular joint of the patient in a state where a mastication protrusion part, provided on the coupling bite, and the corresponding antagonistic part are mutually occluded, and transmitting the images t

Abstract: To accurately acquire an image of an inside of an oral cavity of a person to be treated, there is provided a dental retractor including a retracting base portion that includes an inner retracting portion extending in an arch-shaped profile to surround an inner portion of gum at any one side of an upper jaw and a lower jaw inside an oral cavity and having a pressing holding portion formed at an outer peripheral surface so that a tongue is accommodated therein and an outer retracting portion integrally extending from both ends of the inner retracting portion and extending in an arch-shaped profile to surround an outer portion of the gum, and a handle portion including a grip portion connected outward from the retracting base portion.

Abstract: Provided is a method for manufacturing a surgical guide, and a crown and an abutment in a mouth for a dental implant, including an operation of obtaining a primarily scanned image through scanning of inner and outer surfaces of a denture which has a first image matching groove matched with a patient's tooth implanting portion and in which a plurality of reference markers are attached to an outside, obtaining a secondarily scanned image through oral scanning of upper and lower jaws while the denture is installed, preliminarily matching the secondarily scanned image with the primarily scanned image, obtaining an integrated scanned image considering a vertical dimension by reversing the first image matching groove so that an image of the first image matching groove is dimensionalized from the primarily scanned image, and obtaining a CT image through CT scanning of the upper and lower jaws.

Abstract: Disclosed is a dental implant insertion set including a crown; a fixture which has a hex hole formed therein and of which an insertion angle is set so that the hex hole is aligned corresponding to an arrangement angle of the crown; a guide stent including a stent body formed with a profile set through the three-dimensional procedure guide image to be fixed while covering the periodontal tissue; and an abutment having a hex protrusion formed at a lower portion thereof to be matched with and fixed into the hex hole, such that the crown is aligned and fixed.
