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.

This invention discloses a dental implant able to enhance stability for solving the problem of insufficient support of prior arts. The dental implant of this invention includes: a first threaded section having a first diameter which decreases toward a free end of the first threaded section along a longitudinal axis; a second threaded section connected with the first threaded section and having a second diameter larger than the first diameter; a cut-in section obliquely extending from one end, away from the first threaded section, of the second threaded section outwards and having a tip with a feature of sharpness for cutting into an alveolar bone of a patent in a dental implant surgery; and a head section connected with the cut-in section for receiving a force to facilitate the dental implant to move into the alveolar bone. The dental implant of this invention can enhance preliminary and long-term stability.

A virtual model of an intraoral cavity is provided, wherein this process is initialized by a dental clinic, and the design and manufacture of a suitable dental prosthesis for the intraoral cavity is shared between a dental lab and a service center.

A customizable implant made of plastic including a thermoplastic which is reinforced with long fibers arranged multidirectionally in a targeted manner and has a modulus of elasticity E of 10-70 GPa is provided. A system for producing a customizable implant including a device for collecting patient data regarding the environment into which an implant is to be inserted, a computer program for creating a model for a customized implant based on the patient data collected, and a device for producing the customized implant based on the calculated model by means of 3D printing and/or laser sintering is also provided.

Provided is a method of forming a customized alveolar bone tissue. The method includes obtaining first data having image information corresponding to an original alveolar bone of an alveolar bone defect, obtaining second data having image information on a defective portion of the alveolar bone defect, calculating third data having image information on a barrier membrane covering the alveolar bone defect by using the first data and the second data, and forming a barrier membrane artificial tissue corresponding to the barrier membrane by using the third data.

An implant to retain facial or dental prostheses includes a bone-engaging portion, a transmucosal portion, and an abutment portion. The bone-engaging portion of the implant includes a longitudinally extending distal portion formed of a conformal microscale cell structure and, optionally, a non-biological coating. The transmucosal portion includes a plurality of micro holes. The abutment portion of the implant may be polished to a mirrored or super-mirrored finish.

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.

The invention relates to a method for the non-invasive fragmentation of residual biomaterial after bone augmentation, and to a device specifically adapted for said method.

Methods for generating and providing a full arch prosthesis from a pre-existing prosthesis are presented, starting from the pre-existing prosthesis. This prosthesis is removed from the mouth, scanned, and replaced within the mouth. An intermediate prosthesis is generated from the scan, and modified to match a final physiological target configuration of the patient's mouth. The intermediate prosthesis is used to generate a final virtual representation of the target configuration, from which final virtual representation the final working prosthesis is fabricated. The intermediate prosthesis is mounted in the patient's mouth in sections, for desirable repositioning, sections then being bonded together. Copings can be digitally subtracted to enable press fit new copings to be installed. Alternatively, the intermediate prosthesis can include integrated false copings. The intermediate prosthesis is scanned to generate a final digital model or virtual representation of the desired final prosthesis. The final working prosthesis may then be fabricated using the final virtual representation.
