Disclosed is a method of manufacturing a digital overdenture to improve manufacturing convenience and preciseness. The method of manufacturing the digital overdenture according to the present invention includes a series of operations such as generating a planning image, manufacturing auxiliary devices for manufacturing the overdenture such as a surgical guide, a flattening guide, an impression model, and the like, setting a holder device and correcting a temporary denture, obtaining a corrected-scanned image, and designing and manufacturing a digital overdenture.

The present disclosure discloses an implanting sleeve with function of axial direction checking, relates to the technical field of oral medical instruments, and has the functions of guiding and axial direction checking. The implanting sleeve comprises a sleeve body which can be detachably disposed on a guide plate, the sleeve body is provided with a center hole center hole which allows an implant drill or an implant to pass through, the sleeve body extends and is provided with an extension arm center hole, and a measurement component used for checking the axial direction of the implant drill or the implant is connected to the side of the extension arm away from the guide plate. Through the arrangement of the center hole center hole, the implant drill is guided, and by using of the measurement component, the axial direction of the drilling needle is simply and quickly checked.

A cradle, assembly, system, and method for installing a prosthesis at a surgical site. The cradle temporarily engages the prosthesis and holds it in the correct orientation and position adjacent the surgical site. An aperture is defined in the cradle and a portion of the prosthesis is received therein. In one embodiment, the cradle, assembly and system are used to install a final dental prosthesis in a patient's mouth in a single visit to the dentist's office. A securement member pins the surgical template and subsequently the cradle to the jaw. A metal sub-structure on the final dental prosthesis is received in the aperture in the cradle. Cylinders attached to implants anchored in the jaw extend through holes in the sub-structure and are bonded to the prosthesis. The cradle is detached from the jaw and from the prosthesis prior to screws being re-inserted through the cylinders and into the implants.

A dental implant positioning and guiding assembly is disclosed in the present invention. The dental implant positioning and guiding assembly includes a positioning rod, a convex element, a concave element, a connector and a plurality of guiding elements. The positioning rod is utilized to be inserted into a drilled hole in a patient's oral model. The convex element has a through hole for holding the positioning rod. The concave element is positionally assemble with the convex element. The connector is fixed to one side of the concave element and has a contact surface with a surface contour matching an oral contour of the patient for engaging with the oral contour. Each of the guiding elements is positionally assembled with the concave element and has an open with a curve guiding surface for guiding the surgery operator to drill the at least one implant hole.

A system stores clustering information obtained by clustering multiple sets of viewpoints relative to teeth of a three-dimensional model of a patient and projection images of a head including the teeth from the respective viewpoints. At the time of a surgery, the system creates comparative images from a photographed image taken by a monocular camera and searches for any viewpoint having a projection image similar to the comparative image sequentially from a first hierarchy to a final hierarchy in the clustering information. The system sets a representative viewpoint based on the viewpoint of the final hierarchy, restores position and posture of the teeth of the patient relative to the monocular camera as position and posture of the teeth of the three-dimensional model relative to the representative viewpoint, and generates and outputs a navigation image based on position and posture of surgical information relative to the teeth after the restoration.

A dental tools system with a plurality of guide tabs; a mold and a plurality of tissue punch heads. The mold has a plurality of mold holes, each mold hole having a top portion and a bottom portion. Each guide tab fits in the top portion of one of the mold holes and each tissue punch head fits in the top portion of one of the mold holes. A method of placing dental implants is also described.

An apparatus for guiding a zygomatic implant dental drill installed in a dental handpiece includes a collar configured to seat on a neck portion of the dental handpiece, with an offset post extending from the collar. A first extension extends from the offset post parallel to the neck portion, and a second extension extends from the first extension. The second extension is oriented parallel to the zygomatic implant dental drill, extending from the first extension to be co-terminal and off-set from the zygomatic implant dental drill. By observing the travel of the second extension along a patient's face, a dental surgeon can guide the zygomatic implant dental drill inside the patient toward the patient's zygomatic bone.

A system for electromagnetic navigation in dental implant placement may include an electromagnetic tracking system that may be configured to track positions and orientations of a plurality of electromagnetic sensors. An exemplary electromagnetic tracking system may include a field generator that may be attached to a dental unit utilizing a positioning arm. An exemplary system may further include a control unit that may be coupled to the electromagnetic tracking system and the positioning arm. The control unit may be configured to receive the tracked positions of the plurality of the electromagnetic sensors from the electromagnetic tracking system and to adjust at least a position or an angular orientation of the field generator to maintain the plurality of the electromagnetic sensors within a volume of interest within the tracking volume.

Disclosed herein is method for designing a dental prosthesis and a positioning guide for placing the dental prosthesis on implants in the jaw while maintain proper occlusion. In particular the method relates to a method for designing the dental prosthesis and the positioning guide prior to implant placement. Accordingly, the disclosure relates to a method and a kit of components suited for one-day implant surgery thereby reducing the time the patient spend in the dentist chair.

The kit (1) for the execution of post-extraction dental implant surgery comprises: a plurality of groups (4, 5, 6) of dental implants (7) having a characteristic diameter (D1, D2, D3), the characteristic diameter (D1, D2, D3) of each group (4, 5, 6) being different from the characteristic diameter (D1, D2, D3) of the other groups (4, 5, 6); and plurality of dental drills (18, 19, 20), each of which is provided with: a proximal portion (11); a working median portion (12), having a reference diameter (d1, d2, d3); a non-working distal portion (13);
wherein each dental drill (18, 19, 20) corresponds to one of groups (4, 5, 6) of dental implants (7) and has the reference diameter (d1, d2, d3) which is substantially matching the characteristic diameter (D1, D2, D3) of the corresponding group (4, 5, 6) of dental implants (7).
