Abstract: Embodiments may provide a method for measuring a site of bone graft and an amount of bone graft around a virtual fixture. To this end, according to embodiments, a type of bone defect may be determined based on bone density information of an alveolar bone around a virtual fixture, and the site of bone graft and the amount of bone graft may be determined according to the determined type of bone defect. According to embodiments, there is an advantageous effect that accurate information can be provided to a user to enable precise grafting during implant surgery.

Abstract: A clear alignment attachment design method and clear aligners are disclosed. A clear alignment attachment design method and clear anglers, according to one embodiment, display and provide, on individual teeth, as identifiable visual information, whether an additional attachment needs to be attached during clear alignment, and thus can improve teeth-straightening speed and accuracy.

Abstract: Disclosed are a digital tooth setup method using a graphical user interface for tooth setup and a device therefor. The digital tooth setup method according to an embodiment can dispose, on a loop-shaped guide interface, a manipulator including at least one of a tooth fine-adjustment interface and an interface for a treatment technique. Therefore, use convenience can be increased when teeth are set up by using the manipulator.

Abstract: A margin line point picking method and a dental CAD device for the same are disclosed. In a margin line point picking method according to one embodiment, while a user picks a margin line point, a preset optimum margin line point is recommended by showing a preview thereof on a screen. Accordingly, it is possible to address the inconvenience that the user has to find and pick an accurate point.

Abstract: A transparent braces design method and an apparatus therefor are disclosed. A transparent braces design method and an apparatus therefor, according to one embodiment, predict the influence of adjacent teeth, which can occur when teeth move, when predicting, before treatment, the result of orthodontic treatment using transparent braces, and apply the prediction to a treatment plan, and thus can improve treatment efficiency.

Abstract: A maxillary sinus lifting simulation method and an apparatus therefor are disclosed. According to the maxillary sinus lifting simulation method and apparatus therefor according to one embodiment, in a case in which an implant placed while performing implant placement simulation in a dental image involves the maxillary sinus, a maxillary sinus lifting simulation is automatically performed to display maxillary sinus lifting simulation information in the dental image. In this way, convenience of use can be improved, and errors can be reduced.

Abstract: The present disclosure relates to a method and device for matching oral model data that can provide matching points to a user to match oral model data and computerized tomography (CT) data even for edentulous patients. In this way, convenience is increased and matched data can be effectively generated even for edentulous patients for whom matching has been difficult conventionally.

One embodiment provides an implant surgery planning method using automatic placement of an implant structure, a user interface providing method therefor, and a teeth image processing device therefor, wherein during planning, placement of an implant structure is automatically performed with respect to all mis sing-tooth areas as well as a single missing-tooth area in a teeth image, and placement of an implant structure is automatically performed on the basis of information on relation with a surrounding structure of the missing-tooth area, whereby the present invention increases a user's convenience.

Abstract: An implant bite registration jig includes a coupling portion configured to produce a clear impression in bite impression material; a connecting portion that connects the implant jig with a fixture embedded in a patient's gums; and a body that is formed between the coupling portion and the connecting portion. The implant bite registration jig is positioned in an embedded fixture and a bite impression is taken. Reference marks are formed in the bite impression material by the registration jig, which permit accurate location of the fixture. This makes it possible to simultaneously take a dental impression and a bite impression in an implant operation, similar to a natural teeth operation, such that it is possible to reduce the cost and time for manufacturing a prosthesis.

Abstract: A screw for dental implants, used to fix dental prostheses to abutments combined with fixtures previously inserted in the alveolar bone, includes a screw portion and a screw-head portion. The screw-head portion includes a pair of inclined planes on either side of a center line, wherein the inclined planes form a V-character shape when seen from the side along a center line, each forming at a predetermined angle with respect to a plane perpendicular to the axis of the screw and a tool-receiver, formed between the inclined planes along a center line crossing an upper face of the screw, for transmitting working torque exerted by a tool. A screw set for dental implants includes a plurality of dental-implant screws, each having a screw portion and a screw-head portion of varying height, and each screw-head portion includes the same combination of guide and tool-receiver. The improved screw facilitates tightening and untightening of the screw.
