A dental implant system including a dental implant (1) and an associated implant analog (50), the implant extending along a longitudinal axis (L1) from an apical end (101) to a coronal end (102) and having an external surface for anchoring and osseointegrating in bone, a coronal end portion (105) having abutment connection geometry for cooperating with an abutment which can be seated in one or more defined positions on the implant, the abutment connection geometry having a coronally facing abutment contact surface (128) which extends around the full circumference of the implant, and in use directly contacts the abutment and provides a stop defining the axial location of the abutment relative to the implant, the coronal end portion further having a coronally facing prosthesis contact surface (129) located radially beyond the abutment contact surface, the prosthesis contact surface being a continuous surface extending around the full circumference of the implant.

An impression post for connection to a dental implant, the impression post having a post element being connectible to the dental implant, is disclosed. An annular emergence element is detachably connected to the post element. An inner diameter of the emergence element is configured and adapted to an outer diameter of an axial portion on the post element, and the emergence element can be held in place in a predeterminable axial position of a longitudinal extent of the post element by a positioning element.

A method of installing a dental prosthetic device includes securing a first guide member to an alveolar arch in a mouth of a patient. The first guide member is utilized to achieve a substantially planar bone surface along the alveolar arch. A second guide member is coupled with the first guide member. The second guide member is utilized to install one or more implants in the alveolar arch through substantially planar bone surface. A dental prosthetic is secured to the one or more implants. The dental prosthetic includes nanoceramic material.

The invention relates to an implant for osseointegration into a jaw bone, having a receiving opening one section of which is designed as an inner polygon, and at its distal end, the implant includes an indexing that reproduces the geometry of the inner polygon.

A scan posts system with scan posts is presented. Each scan post includes a scan post core and a scan post body surrounding the core and resting in the shoulder of the core. At least part of the scan post body is intended to be in contact with healing tissue. Each scan post body belongs to a group of scan post bodies including at least a combination of two different shapes with three different sizes and at least one height. Each scan post body includes at least one scan mark suitable for providing information about the shape, size and height of the scan post to a scanning device, this information being useful for designing a dental implant prosthesis. A method of manufacturing a dental implant prosthesis using such a system is also presented.

A temporary alignment system and method for holding a dental coping to an implant abutment using the same threads in the abutment that are used for definitive attachment are disclosed. The disclosed temporary fasteners initially orient and hold a coping against an abutment with a force along the same axis as the semi-definitive screw. The aligned coping can be picked-up in a closed-tray impression process without unscrewing the temporary fastener. Embodiments include threaded posts that release copings from the abutment through axial forces. Some embodiments include a threaded post with separable cap that is picked-up with the coping. Methods for converting an existing prosthesis for screw attachment to implants in a single visit and digital capture of the converted prosthesis are described.

A carrier tool is proposed that may be used in combination with a dental torque wrench to easily access all dental implants, regardless of their location within the mount. The carrier tool comprises a shaft for extending the reach of the wrench, with a shortened mount attached to an opposing end of the shaft. The shorted mount is used to securely hold the implant measurement device during insertion within the implant. A magnet is disposed within the interior of the mount to secure the implant measurement device (also magnetized) in place as the carrier tool is brought into the proper position with respect to the implant.

A method of providing an accurate three-dimensional scan of a dental arch area is disclosed. The arch area has two segments and a connecting area between the two segments. The connecting area has homogeneous features. A connecting-geometry tool with at least one definable feature is affixed to the arch area. The definable feature overlays at least part of the connecting area. The arch area is scanned to produce a scanned dataset of the arch area. The definable feature of the connecting-geometry tool on the connection area is determined based on the scanned dataset. The dimensions of the arch area are determined based on the data relating to the definable features from the scanned dataset.

The present disclosure provides an implant surgery guiding method of guiding a position, direction and depth of a fixture to a dentist by real-time images. The implant surgery guiding method includes: (a) generating a 3D oral cavity image for a patient; (b) designing a target placement including a target position and a target orientation of a fixture based in the 3D oral cavity image; (c) attaching an oral marker comprising a first pattern to a jawbone or a surrounding body portion of the patient, determining a spatial relationship between the oral marker and the jawbone, attaching a handpiece marker comprising a second pattern on a handpiece of a dentist, and determining a spatial relationship between the handpiece marker and the handpiece; and (d) estimating positions and orientations of the jawbone and the handpiece based on changes in positions and orientations of the oral marker and the handpiece marker while tracking the motions of the oral marker and the handpiece marker, and displaying a jawbone image portion and a handpiece image portion on a screen reflecting real-time changes in the positions and orientations of the jawbone and the handpiece.

A method for making a rapid prototype of a patient's mouth to be used in the design and fabrication of a dental prosthesis. The method takes an impression of a mouth including a first installation site having a dental implant installed in the first installation site and a gingival healing abutment having at least one informational marker attached to the dental implant. A stone model is prepared based on the impression, including teeth models and model markers indicative of the at least one informational marker. The model is scanned. Scan data is generated from the scanning. The scan data is transferred to a CAD program. A three-dimensional model of the installation site is created in the CAD program. The at least one informational marker is determined to gather information for manufacturing the rapid prototype. Rapid prototype dimensional information is developed. The rapid prototype dimensional information is transferred to a rapid prototyping machine which fabricate a rapid prototype of the patient's dentition as well as a dental implant analog position.
