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 surface information of the binding region, in an inner surface profile set according to the three-dimensional surface information of the engagement groove.

A dental surgery guide system for use with a dental handpiece for forming a bore in a patient's jaw bone to receive a dental implant comprises a surgical template and a handpiece jig; the top of the handpiece guide can slide below the top of the template guide rail.

Ablation probe tips (108, 148, 320, 360) and physical and virtual stents (110) for use in tooth bud ablation procedures that result in tooth agenesis as well as tooth bud ablation methods are described herein.

The invention relates to a method for manufacturing at least one bone anchor and a corresponding drilling template, wherein the bone anchor has an anchor plate which is to be fixed to the surface of a bone by means of one or several screws having a screw head. The anchor plate thus has a bone side which is to connect to the surface of the bone and a free side which is opposite to said bone side. Further, the invention concerns a method for manufacturing a drilling template making it possible to make bore holes in the bone at predetermined positions and to screw the bone anchor to said bone according to predetermined orientations.

An autograft forming bone anchor is provided including an elongated anchor core having a tip at a distal end and coupled to a head at a proximal end, and a segmented helical thread defining one or more gaps therein, each gap defining at least a trailing wall, the trailing wall having a cutting surface including at least one cutting edge. A plane of the cutting surface that extends through a point of contact of the cutting surface with the anchor core and the cutting edge, is angled at an angle (α) with respect to a radius (r) of the bone anchor, and the bone cutting surface and the cutting edge are configured to cut bone and guide bone fragments radially inwards. Other embodiments are also described.

An accurate and precise surgical guide for dental procedures, especially a procedure involving a subject with few or no teeth as well as methods for making and use of such guides.

Disclosed are 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. 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.

Disclosed are a multiple bone displaying method for establishing an implant procedure plan, and an image processing device therefor. A multiple bone density displaying method according to one embodiment comprises, during the establishment of an implant procedure plan, the steps of: generating a virtual bone density display area centered with respect to an implanted fixture in a dental image, so as to overlay same on the fixture position; analyzing the bone density corresponding to the bone density display area; and displaying the analyzed bone density as color information in the bone density display area.

Systems and methods of the present disclosure relate to augmented reality (AR) assisted surgery. A system comprises a spatial virtual surgical treatment plan (SVSTP) for mixed or virtual reality; multiple AR interfaces (ARIs), each ARI configured to overlay the SVSTP onto a surgical site, wherein the ARIs are positioned at different angles to provide an unobstructed view of the surgical site and reduce parallax and occlusion errors during surgery, wherein the ARIs are configured to exchange coordinate information with each other such that the SVSTP viewed from each ARI is overlaid upon the surgical site and superimposed with each other to guide a surgical instrument.

The invention relates to manufacturing a surgical guide to be placed in a patient's mouth. The patient's mouth is scanned to obtain surgical-region scan data at a region where an implant is to be located. The patient's mouth is also scanned in the opened position to acquire dental conditions opposite from the surgical region so as to obtain opposing-condition scan data. A virtual model is developed using the surgical-region scan data and the opposing-condition scan data. Using the virtual model, a surgical plan is developed that includes the location of the implant to be installed in the patient. A virtual surgical guide is also developed based on the surgical plan. The dimensions of instrumentation to be used with the surgical guide are checked to ensure they will tit within the mouth by use of the opposing-condition scan data. After checking, final surgical-guide manufacturing information is obtained for manufacturing the surgical guide.
