A dental drill guiding system includes a drill guide including a hollow tube having an exterior surface and a guide sleeve including an internal surface defining a through bore configured to receive the hollow tube of the drill guide. The exterior surface of the hollow tube and guide sleeve's internal surface have complementary anti-rotation sections. The drill guide's hollow tube further includes at least one radially extending protrusion limited in the axial extent and formed by an increase in radius of the hollow tube in the apical direction and dimensioned for accommodation in at least one undercut of the guide sleeve, such that when at least one protrusion of the hollow tube is housed in at least one undercut of the guide sleeve the hollow tube is axially retained within the guide sleeve such that removal of the drill guide from the guide sleeve in the coronal direction is prevented.

A bone foundation guide system and method, the system could includes a bone foundation guide including a body forming an open surgical space, the body further having a bottom contoured to reversibly affix to exposed bone of a dental surgical site and a top contoured to match a bottom side of a dental implant surgical guide; at least one anchoring strut that removably attaches to the body with an apex of the anchoring strut further denoting one or more indentations for matching up with and receiving one or more portions of one alveolar ridge that opposes another alveolar ridge supporting the dental surgical site; alternatively to the anchoring struts and a tissue spacing gasket, the dental implant surgical guide that removably connects to the body; and alternatively to the anchoring struts or the dental implant surgical guide, the tissue spacing gasket that removably connects to the body.

Aspects of the present disclosure relate to systems, devices and methods for performing a surgical step or surgical procedure with visual guidance using an optical head mounted display. Aspects of the present disclosure relate to systems, devices and methods for displaying, placing, fitting, sizing, selecting, aligning, moving a virtual implant on a physical anatomic structure of a patient and, optionally, modifying or changing the displaying, placing, fitting, sizing, selecting, aligning, moving, for example based on kinematic information.

Apparatus and method for installing a multi-tooth dental prosthesis in one session are shown and described. A first tool attaches to the jawbone, and serves as a foundation for subsequently used guides. Existing teeth and dental fixtures are removed, and the bone tissue is removed to accommodate the prosthesis. Subsequently, a drill guide is used to drill implant holes. An abutment guide is then used to place abutments. Copings are then installed. Next, the prosthesis may be installed and cemented to the copings. A resinous filler material may be applied to fill gaps and holes in and between the copings and the prosthesis, and is sanded smooth.

Disclosed are a surgical guide plate and a preparation method therefor. The preparation method comprises the following steps: a) bonding a radiation-blocking material onto an oral mucosa, and putting on an occlusal rim; b) carrying out CBCT photographing to acquire CBCT data carrying information of the radiation-blocking material; c) acquiring STL data of an oral cavity surface; d) matching the CBCT data with the STL data; e) loading occlusal rim data; f) carrying out intelligent tooth arrangement; and g) designing an implant, and generating a surgical guide plate. By means of the preparation method, the level of comfort of a patient can be increased, preparatory processes are reduced, a radiation guide plate does not need to be made, the number of return visits is reduced, the clinical medical cost is reduced, the precision of a surgical guide plate is increased, the software design time is reduced, and the treatment experience is improved.

A robotic system and method involve a fiducial marker engaged with a maxillofacial anatomy, and an end effector at a distal end of an articulating arm member. The end effector receives a dental element comprising a prosthetic device, a surgical guide, or an orthognathic element, in a predetermined spatial relationship therewith. A controller device directly communicates with the fiducial marker, the articulating arm member, and the end effector, to determine an end effector disposition relative to the fiducial marker during end effector movement according to a virtual procedure plan for placing the dental element in aligned relation to the maxillofacial anatomy, and directs the articulating arm member to physically control allowable movement of the end effector, directly relative to the disposition of the end effector with respect to the fiducial marker and according to the virtual procedure plan, to place the dental element for securement to the maxillofacial anatomy.

A method for detecting alignment of a drill sleeve in a drilling template relative to the jaw of a person, includes: creating an impression element including a negative impression of the jaw structure; creating an X-ray template from the impression element by disposing spaced X-ray visible reference bodies in the impression element; carrying out a first three-dimensional radiological detection, in which the jaw, together with the X-ray template fastened to the jaw, is detected by DVT or CT; creating a drilling template from the X-ray template by fastening a drilling sleeve in/on the X-ray template; inserting a reference object, including spaced X-ray visible reference bodies, into the drill sleeve; and carrying out a second three-dimensional radiological detection, in which only the drilling template, which is outside the jaw, including the reference bodies thereof, and the reference object inserted therein, including the reference bodies thereof, are detected.

A direction checking pin and a guide tap drill kit for insertion of a fixture for an implant includes an endosseous fixing guide, a direction checking pin body and a guide tap drill. The endosseous fixing guide and the direction checking pin body are combined and then inserted into an already-formed insertion hole and only the direction checking pin body is removed after checking a direction of the insertion hole, and the guide tap drill is inserted to the endosseous fixing guide remaining in the insertion hole and then rotated so as to enter into the insertion hole such that a screw thread is formed in accordance with the direction of the insertion hole at an inner wall of the insertion hole by the tap drill.

The invention relates to a method for partial curing of an initial photoreactive material for 3D printing, comprising the steps of:

a) providing an item (1) comprising the initial photoreactive material for 3D printing,

b) a partial irradiation step comprising irradiating at least one curing section (20) of the initial photoreactive material for 3D printing of the item with a curing irradiation, yielding at least one cured section (120) of a partially-cured item (10), and at least one semi-curing section (40) of the initial photoreactive material of the item is irradiated with a semi-curing irradiation, yielding at least one semi-cured section (140) of the partially-cured item.

A method including fixing a dental drill template with a fixation pin including a rod and a head attached to the rod. The dental drill template can be fixed by inserting the rod into the drill template or a sleeve provided in the drill template such that a bearing surface of the head bears at least partially on the drill template. The rod has a shape of an essentially circular cylinder and extends from the bearing surface of the head at an essentially right angle. A diameter of the head at the bearing surface is larger than the diameter of the rod.
