A method and a device for the simplified inspection of the compatibility of the positions of master tubes in a surgical guides with respect to the positions in a predetermined plan in a computer model. For example, during virtual planning, the virtual surgical guide includes master tubes having an axis that is the axis (e.g., an installation axis) along which a dental implant will be installed. The virtual surgical guide can be manufactured, e.g., by substrative methods and additive methods. As discussed herein, the accuracy of the physical surgical guide can be checked physically or virtually.

Disclosed herein a surgical tool set for implant having an implantation driver for implanting a fixture. The implantation driver comprising: a first supporting portion disposed radially in an engagement portion that transmits implantation torque to the fixture; and at least one second supporting portion that is disposed radially in the engagement portion so as to be spacedly apart from the first supporting portion and is arranged asymmetrically with respect to a center point located on a central axis of the implantation driver. The second supporting portion has a larger size than the first supporting portion along at least one of an outer circumference direction and a radial direction of the engagement portion.

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 dental implant includes a fixture implanted into an alveolar bone, an abutment fixed to an upper part of the fixture and having a core hole formed in a center of an upper surface of the abutment, a crown bonded to an upper outer side of the abutment and having a passage vertically formed through a center of the crown, and a cover screw having a screw screw-fastened to the core hole and a head in close contact between an upper surface of the abutment and a lower surface of the crow to cover the core hole, in which, when the screw is released by a tool passing through the passage, the head moves up so that the cover screw provides a separating force to the crown. The dental implant may facilitate a separation of the crown and prevent binding force from weakening, thereby enabling an efficient procedure and management.

A handpiece-type high-frequency vibration cutting device includes a housing (10); a vibration device (21); a holding member (11); a tool (12); and a controller (20) to control the operations of the vibration device (21). The controller (20) controls the vibration of the tool (12) due to the vibration device (21) such that the vibration is burst oscillation in which vibration and stop of vibration are repeated. The controller (20) also controls the entire burst frequency f1 of the tool (12) to be included in the range of 1 to 8 [Hz], one cycle of the burst frequency f1 including a burst period with the holding member (11) vibrating and a stop period with the tool (12) not vibrating. The controller (20) also controls the vibration frequency f2 of the tool (12) during the burst period such that the vibration frequency f2 is in the range of 20 to 60 [kHz].

A dental implant locator cleaning assembly includes a cleaning head that is attachable to a periodontal tool which employs oscillation and pressurized water for cleaning dental implants. The cleaning head has a plurality of tabs oriented to surround a dental implant locator for scrubbing an outer surface of the dental implant locator when the periodontal tool is turned on. The cleaning head has a fluid nozzle that is centrally positioned therein and is surrounded by the plurality of tabs. The fluid nozzle extends into a well in the dental implant locator and the fluid nozzle is in fluid communication with the periodontal tool when the cleaning head is attached to the periodontal tool. In this way the fluid nozzle can spray a fluid into the well in the dental implant locator for cleaning debris from the well in the dental implant locator.

The present invention relates to a dental implant analog, an implant analog kit comprising the dental implant analog, the combination of a physical model of a set of a patient's teeth and the dental implant analog and a method of positioning a dental implant analog into a physical model of a set of a patient's 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.

A cortical drill for hydrating and drilling cancellous bone when preparing a dental implant includes a stem portion and a drill portion, the stem portion with a locking notch and a water inlet configured for receiving fluid under pressure into the cortical drill. The drill portion has an elongated substantially conical body having an outer wall. The drill portion has a slot portion, and the slot portion includes a cut-out forming an inlet along a peripheral surface of the conical body. A plurality of jets are formed in the slot portion, with the jets in communication with the water inlet, and the jets arranged along the slot portion, such that fluid travelling under pressure into the water inlet, travels through the stem portion and the drill portion, and exits the jets in the slot portion.

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.
