The subject matter of the instant invention relates to a dental implant surgical apparatus and system comprising a customized dental ridge augmentation matrix and one or, optionally, a plurality of dental implant surgical drill guides, and methods of use thereof.

A curved handpiece for dental root canal treatment forms an overall scheme of a dental curved handpiece, which is internally conductive, surface insulated, compact in structure, small in height and size and convenient to repair. A dental root canal length measuring function can be realized accurately, safely and stably, and a stable two-in-one function of combining root canal preparation and dental root canal length measurement is further realized. The structure is compact as a whole, and a good visual field is provided. The risk of instrument separation or preparation step generation in the operation process of doctors is reduced, and the safety improvement is greatly guaranteed. According to the scheme, it is convenient to disassemble, repair and clean, the risk of cross infection is reduced, and the use safety and convenience effects of the present invention are further improved. The curved handpiece has great market benefits.

A new and improved drill bit for preparing a dental implant site within a jawbone for the implantation of a dental implant, as a result of being rotatably driven by a motor drive, comprises a body portion which includes an upper shank portion to be inserted into the motor drive, and a lower drilling portion for forming a hole or bore with a jawbone within which a dental implant is to be implanted. The lower drilling portion includes a pointed conical tip portion having an apex for determining the location of the implantation site, and the outer diametrical extent of the lower drilling portion progressively increases in diameter as considered in the direction from the apex to the upper shank portion so as to automatically enlarge the hole or bore formed within the jawbone such that the complete drilling process can be completed within a single drilling operation as opposed to conventional operations which require the use of a plurality of drill bits of increasingly larger diametrical extents.

A drilling jig for drilling a drill hole into a jaw of a patient for a medical tooth implant. The drilling jig includes a prosthesis adapted to at least one of teeth and the jaw of the patient and a drilling model. The prosthesis has a bipartite design and includes an individualized part adapted to the teeth, and a standardized plate part with at least two reference markers suitable to provide reference points in digital images of the prosthesis and a first coupling part which couples the drilling model to the prosthesis. The drilling model is a standardized part which includes a drill channel adapted to the medical tooth implant, and a second coupling part adaptable to the prosthesis so that the prosthesis and the drilling model are connectable with each other through the first and second coupling parts.

A method for referencing a tracking system's coordinate frame to a rigid body's coordinate frame is disclosed. The method involves obtaining a 3D model depicting some of the surfaces of the rigid body. A probe is provided with an affixed tracking reference component. A second tracking reference component is attached to the rigid body. The method involves tracking locations of the probe as it moves along surfaces of the rigid body and then determining a transform that relates the probe locations to the 3D model of the rigid body. In one embodiment the rigid body is a dental mandible or maxilla of a patient and the 3D model is a surface extracted from a computed tomography image of the patient's jaw and teeth.

This document describes a set of surgical drill guides for the upper and lower jaw, the guides aimed at locating the ideal position for dental implants in edentulous patients. The guides are made up of a surgical stent material from metal or other rigid material that is aligned to provide support and stability of fully edentulous upper and lower jaw to orient surgical drills in the area of operation. The present embodiment comprises a U-shape metal plate provided form or shaped resembling a toothless upper or lower jaw and containing a top surface of the surgical stent that is contacting the soft tissue of maxilla or mandibula and the bottom surface of the stent that has the same shape as a top one.

The present invention relates to a centering and guiding device (1) for a dental drill which comprises a body (10) including a guiding hole (15) for a dental drill and two arms (20, 30) pivotally coupled to the body (10). Each arm includes a respective free end (22, 32). Said arms (20,30) are capable of pivoting between a first open position, in which said respective free ends (22, 32) are mutually spaced apart to promote the movement of the device (1) from and towards an operating surface, and a second closed position, in which the free ends (22, 32) are approached to each other to match an operating surface. The device according to the invention also comprises an elastic element (40) to push the arms (20, 30) towards the closed position. According to the invention, each of said arms (20, 30) comprises a cylindrical end (27, 37), opposite to the corresponding free end (22, 32), accommodated in a corresponding seat (10A) defined by the body (10). Moreover, the cylindrical ends (27, 37) of said arms (20, 30) comprise respective toothed sectors (25, 35) mutually meshing each other to guide the rotation of said arms (20, 30) between said closed and open positions.

A first guide member includes a horizontal body portion and a pair of upright portions. The horizontal body portion has an arcuate configuration and includes a first horizontal surface, a front surface, a rear surface, and a second horizontal surface. The first horizontal surface is flat. The first upright body portion includes a first inwardly extending portion. A first engagement surface of the first inwardly extending portion is configured to rest on a ridge of the alveolar arch of the patient. The second upright body portion includes a second inwardly extending portion. A second engagement surface of the second inwardly extending portion is configured to rest on a ridge of the alveolar arch of the patient. The first guide member lacks a component configured to extend along a lingual or palatal side of the alveolar arch of the patient.

An aspect of some embodiments of the present invention relates to solutions for the removal of dental implant screws with stripped heads and/or dental implant screws that are difficult to remove. Optionally, the method for removing a dental implant screw comprises a method for removing the head from the shaft of a dental implant screw, for example by drilling. Once the head is removed, the abutment is optionally removed, thereby exposing the threaded screw shaft within the fixture of the implant and/or the mount for aligning the abutment. Optionally, removal of the abutment allows use the attachment to guide removal of a screw shaft.
