Dental implants including radiopaque markers provided therein or thereon. The implant may also include customizable length characteristics. For example, a kit may include implants with different diameters (e.g., 3 diameters), where all of the implants are of a single (e.g., long) length. The appropriate diameter implant may be selected from the kit by the practitioner, and the long length implant may be cut (e.g., with a dental drill) to the appropriate length needed. The implants include radiopaque markers on or within the implant. For example, three series of markers may be provided on different faces of the implant, so that the three series of markers serve as reference points when scanning, allowing triangulation of the exact position of the implant in relation to the surrounding hard and soft oral tissues.

An image generation system for implant diagnosis includes a first image information acquirement apparatus acquiring first three-dimensional (3D) image data about a mouth area of a target patient, a second image information acquirement apparatus acquiring second 3D image data by scanning plaster patterns of teeth of the target patient, and a data processing apparatus receiving and matching the first 3D image data and the second 3D image data and generating synthetic 3D image data. In the image generation system, the plaster patterns of teeth are provided with a matching reference marker for matching the first 3D image data and the second 3D image data, and the data processing apparatus pre-matches the first 3D image data and the second 3D image data based on a coordinate of a matching reference marker of the second 3D image data.

A kit and method for tracking a human jaw are provided. The kit and method can involve a bone screw and an extension arm. The bone screw has a threaded portion, a head portion and a longitudinal axis. The threaded portion can have a thread diameter of less than or equal to about 2.5 mm and can be inserted into a bone of the human jaw within 45 of the occlusal plane. The head portion protrudes out of the bone of the human jaw when the threaded portion is inserted into the bone. The extension arm can be rigidly secured to the head portion of the bone screw to maintain a fixed spatial mapping between the head portion of the bone screw and an optically detectable marking provided on the extension arm. When secured to the head portion of the bone screw, the extension arm can be positioned such that the optically detectable marking is detectable by an optical tracking system positioned outside the mouth containing the jaw bone.

A surgical drill type cutting tool includes a shank and an active portion extending in the extension of the shank, with chip areas extending along the active portion, and a ring surrounding a part of the active portion, an inner surface of the ring engaging the active portion without closing off the chip areas, allowing irrigation fluid to provides useful irrigation over most of the length of the active portion of the surgical drill bit.

Methods, devices, systems, and series of appliances are provided for dental implant positioning. One method for positioning an implant with dental treatment includes determining an implant location based on a virtual model of an optimized dental occlusion, moving one or more teeth using a first number of a series of dental appliances, from a first orientation to a second orientation, the second orientation exposing the implant location, placing an implant at the exposed implant location using a landmark included in at least one of the series of dental appliances, repositioning one or more teeth using a second number of the series of dental appliances, from the second orientation to a successive orientation.

A method is used to provide a dental prosthetic with an upper boundary that cannot be seen when a patient smiles with the dental prosthetic installed. The method includes tracing a smile line on a dental appliance while the dental appliance is in the patient's mouth and while the patient is smiling. The method then includes transferring that smile line from the dental appliance to a study cast of the patient's mouth. The study cast is then scanned to create a three-dimensional digital model that includes the transferred smile line. The three-dimensional digital model is used to generate a surgical plan and surgical hardware for installation of the dental prosthetic. The dental prosthetic may include a full arch restoration.

The invention relates to a screw, a tool and a system for dental implantology, forming a fixing system and the components thereof to be used in a dynamic pillar assembly. Said dynamic pillar assembly is used in the production of prostheses on dental implants in human implantology in order to fix screws at an angle.

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.

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 method and system for facilitating the placement of a dental implant device using augmented reality, and simultaneously capturing the result of the placement for subsequent planning procedures. By planning a desired dental implant location using one or more preoperative images of a patient and overlaying the planned dental implant location and the one or more preoperative images on the patient through virtual reality means, a clinician may be provided with an awareness of the positional relationship between the preoperative images and the planned implant position.
