Method and prosthetic system for producing a substitution bridge structure with prosthetic teeth (6), for replacing an existing bridge structure (2) which is mounted on a base structure (1), wherein the base structure (1) is fixed to implants (10) by means of base screws (11) and the head (15) of the base screws (11) has a screw hole. A scan body is fixed to the head (15) of the base screws (11) and an intraoral scan of the oral cavity is executed and the scan data is related to a 3D digital model of the base structure (1) and/or of the existing bridge structure (2), wherein subsequently a 3D digital model of said substitution bridge structure is designed.

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.

A bite registration device including a scan post configured to attach to a dental implant, a bite pillar configured to be attached at a coronal end of the scan post, and a mechanism for attaching the bite pillar to the scan post, wherein the mechanism enables adjustment of a distance from a coronal end of the bite pillar to an apical end of the scan post. A bite pillar including a wide coronal end and an elongate shape configured to attach to an object in a mouth of a patient. A scan post including a screw thread for attaching a bite pillar thereto. A reference pillar configured as an elongate shape to be attached at a first end to an object in a mouth of a patient. Related apparatus and methods are also described.

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.

An apparatus may include an elongated hollow body with a plurality of skirts on one end of the elongated hollow body. An exterior of the elongated hollow body may have a plurality of fins. At least some of the plurality of fins may have a different diameter and/or placement along a length of the elongated hollow body. The elongated hollow body may be configured to receive a screw. The screw may be configured to expand the plurality of skirts upon insertion into an interior of the elongated hollow body. The plurality of fins may be configured to secure the apparatus when the apparatus is placed within a bore. The plurality of fins may secure the apparatus at least by engaging the bore.

Methods and dental prosthetics for providing soft tissue adhesion to a temporary healing abutment, or other dental prosthetic (e.g., temporary or permanent). Existing prosthetics generally do not provide any significant adhesion of the soft tissue surrounding the prosthetic, to the outer surface of the prosthetic itself. Because of the presence of gaps between such structures, or simple non-adhesion even where the structures may touch (but be free and unattached relative to one another), there is a tendency for pathogenic microbes to enter into such space between the structures, and for the soft gingival tissue to recede, particularly in patients with “thin” type periodontal tissue. The present disclosure provides materials and/or surface treatment (e.g., texturing) that ensures good bonding between the prosthetic and the soft tissue, reducing risk of infection, and reducing undesirable gingival recession surrounding the prosthetic anchored on a dental implant.

An abutment is provided with a screw access hole and a slot in its sidewall adapted to allow a driver to access a screw in the screw access hole at an angle relative to a longitudinal axis of the screw. The abutment may include a screw seat and may be connected to an implant via a screw in the screw seat. A prosthesis, which may include a driver access channel that has a diameter less than the outer diameter of the drive portion of the screw, may be placed over the abutment. Methods of making a dental prosthesis and methods of attaching and removing the dental prosthesis from the implant are also disclosed.

In order to improve the reliability of a dental restoration, a method of implanting the dental restoration is provided. The method includes virtually disposing a virtual implant selected from a digital library on the basis of a CT image to correspond to an implantation information, and a virtual implanting guide sleeve, which is virtually and concentrically disposed to be spaced upward from an upper end portion of the virtual implant by an offset distance, and a scanning image overlap and are integrally stored; and generating design information of a surgical guide, wherein a virtual coupling hole corresponding to an outer circumference of the virtual implanting guide sleeve is formed in the design information.

A dental bar is disclosed for accurately determining the separation and relative orientation of two coping cylinders projecting from dental implants in a patients mouth to receive a prosthesis. The dental bar comprises two sockets, for fitting over and securing to the two coping cylinders, connected to one another by a limb formed of telescopically collapsible sections. The telescoped ections of the limb are of differing cross-sectional shape so as to define between them a volume into which a bonding material may be injected through a port, in order to lock all the limb sections permanently relative to one another.

The method of detection of positioning of a dental implant for dental restoration involves taking a manual or digital impression of the buccal space, including a cicatrisation element secured to the implant and having an emergent surface outside the gum, and automatically detecting the positioning of the implant by identifying (i) the axis of the implant corresponding to an axis of the cicatrisation element identified by the geometry of the emergent surface or association with a cicatrisation element memorized in a database; (ii) the orientation of the implant by the orientation of the emergent surface or association with a cicatrisation element memorized in a database; and/or (iii) the height of the implant by the height of the cicatrisation element, for example based on a color or an indicator of the emergent surface or association with a cicatrisation element memorized in a database.
