The palatal region can have a plurality of anchor-receiving features (e.g., anchor interfaces) that allow the palatal expander to be attached to temporary anchorage device anchors that have been implanted into the patient's maxilla.

An aspect of the present invention is a drill assistance device comprising: a drill guide device that serves as a guide when forming a plurality of holes from a curved surface of a hard palate having the curved surface; and a guide sleeve that is fitted in the drill guide device in an attachable and detachable manner. With this device, it is possible to easily and accurately perform the hole making with a drill and the implant of a screw in an oral cavity. The drill guide device comprises: a guide frame unit that is formed by connecting a plurality of tubular guide frames to each other; a fixing member to be capped on a tooth of a patient; a connecting portion that connects the guide frame unit and the fixing member and determines arrangement of the guide frame unit on the curved surface; and at least one protruding portion that holds the guide sleeve inserted in any of holes inside the guide frames. The guide sleeve comprises: a tubular sleeve main body having an inner diameter that allows the drill to be inserted and an outer diameter that allows the sleeve main body to be inserted in any of the guide frames; a water injection slit that is provided in the sleeve main body; and projecting portions that are each fitted in at least one recessed portion provided in the at least one protruding portion when the sleeve main body is inserted in any of the holes of the guide frames.

A bone foundation guide system for a dental implant surgical site has a bone foundation guide and a dental implant surgical guide with an open surgical space therebetween. The top of the foundation guide body is contoured and has an upper surface to attach a bottom surface of the dental implant surgical guide as well as to define a removal and augmentation level and to guide the removal and/or augmentation of bone segments from the dental surgical site via a separation plane. The separation plane has a central area predetermined to define an implant depth of bores for anchoring implants, and further has an inclined area extending from all side ends of the central area towards the first bridge end and the second bridge end raising above the removal and augmentation level of the jaw bone.

The surgical guide tool for single dental implant positioning includes an adjustable U-shaped frame having an inner member and an outer member. The inner member of the frame includes a first arm and a second arm that extends normal to the first arm. The outer member of the frame includes a first arm and a second arm that extends normal to the first arm. The first arm of the outer member includes an inner cavity for slidably receiving the first arm of the inner member. The first arm of the inner member can be moved within the cavity to adjust the size of the frame. A ring, attached to the second arm of the inner member, includes a circular wail with a central aperture extending therethrough. The central aperture is configured for receiving a drill bit therethrough for properly positioning the drill bit on the jawbone.

A drill stopper set including a plurality of stoppers. Each of the plurality of stoppers includes a body. The body has a cylinder shape and includes a top, a bottom, a sidewall, and a bore running along a longitudinal axis of the body from a top opening defined at the top and to a bottom opening defined at the bottom. The bore is sized to receive a dental drill bit. Protrusions extend radially from opposing sides of the sidewall and run from the top towards the bottom of the body. A distance from a bottom edge of the protrusions and the bottom of the body vary between each of the plurality of stoppers.

A surgical cutting tool guide (20, 320, 420, 520) includes a target arm (30) and primary and secondary sight arms (32A, 32B), which are pivotably attached to the target arm (30) so as to be rotatable with respect to one another about primary and secondary target pivot points (34A, 34B), respectively. A sight (40) includes a sight housing (42), which defines a sight passage (44) for aligning a surgical cutting tool (22) with a sight target axis (46), and is attached to the primary and the secondary sight arms (32A, 32B) such that the sight housing (42) and the primary and the secondary sight arms (32A, 32B), respectively, are rotatable with respect to each other about the primary and secondary sight pivot points (34A, 34B), respectively. The surgical cutting tool guide (20, 320, 420, 520) is arranged to automatically and non-electrically maintain the sight target axis (46) oriented to pass within an offset distance of a target point (60) over an entire range of angles over which the sight (40) directs the sight passage (44) toward the target point (60).

An intraoral 3D scanner includes a probe light source configured to generate a probe light such that the probe light is transmitted towards the dental situation; a camera including an array of sensor elements, the camera being arranged such that the probe light from the dental situation is transmitted to the array of sensor elements, wherein the camera is configured to create images of the dental situation from which a point cloud is generated, and a guiding system configured to guide relative movement of the intraoral 3D scanner towards the dental situation, wherein the camera is part of the guiding system, the camera is configured to record images from which a relative position of the intraoral 3D scanner and the dental situation is determined, such that based on the relative position, the guiding system is configured to provide a positioning signal in the form of a positioning color code.

A navigation and monitoring system to track positions of surgical components during surgery of a patient. Some embodiments include a power source to emit a tracking signal during surgery of the patient, a first sensor mounted to a region of the patient to respond to the emitted tracking signal, and a control unit to track a position of the region relative to a fixed region of the patient as the region moves with respect to the fixed region, based on the response of the first sensor. The system can calibrate and register a movable reference point of the patient relative to a fixed reference point, and can maintain that reference point when the movable reference point moves in space during a surgical process.

A dental prosthesis having a guide hole formed therein. The guide hole is configured to guide a drilling for a screw, and configured to receive the screw, holding the prosthesis in place when screwed into the bone of a patient.

A method of implementing a splint device, and associated splint device are provided for a guidance system of a surgical robot. An adhesive material is engaged with a first stabilizing portion of a first splint portion, and the adhesive material is engaged with a second stabilizing portion of a second splint portion. The first or second splint portion has a mounting portion extending outwardly therefrom, The first and second splint portions are removably engaged with each other and about a tooth of a patient such that, when engaged, the first stabilizing portion is generally opposed to and laterally spaced apart from the second stabilizing portion to define a channel therebetween, with the mounting portion being disposed and extending outwardly of the channel, and with the first and second stabilizing portions defining the channel being secured to respective sides of the tooth via the adhesive material.
