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.

A system and method are provided for manufacturing a physical model of a dental structure that includes a dental implant. In at least one example, the physical model is configured to allow a dental analog can be inserted into the physical model in a general coronal direction. A virtual model of the dental structure is provided including a virtual implant spatial disposition with respect to the virtual model corresponding to a physical implant spatial disposition of the dental implant with respect to the physical dental structure. A virtual analog installation structure is defined in the virtual model. Using the virtual model, a physical model corresponding to the virtual model is manufactured, the physical model being provided with a physical analog installation structure corresponding to the virtual analog installation structure. The physical analog installation structure is configured for enabling a dental analog, corresponding to the dental implant, to be inserted in a general coronal direction with respect to the physical model to an installed position in the physical model. In the installed position, the dental analog has an analog spatial disposition with respect to the physical model corresponding to the physical implant spatial disposition of the dental implant with respect to the physical dental structure. A composite physical model, and methods for manufacturing the same, are also provided.

A stable affixation system for dental implantation includes a fixation tray having, for rapid placement, a housing defining a chamber whose inner surface is configured to house a flowable or malleable material and be placed over one or more teeth during guided dental implantation surgery. Housing side walls are joined to a cross member that has a flexion region on each side of the housing, each side wall having an upper side portion and a lower side portion. Without the lock a squeezing force on the upper side portions flexes the lower side portions outward. The lock urges the upper side portions outward so as to flex the lower side portions inward, thereby urging the material, once hardened, against the teeth. The lock reduces or eliminates freedom of movement of the tray. The system allows rapid removal and is sturdy enough to withstand forces including from various angles and leverage.

A scan body member includes a body portion having a first end portion and second end portion opposite the first end portion. A wall portion extends between the first end portion and the second end portion. The wall portion has an exterior surface portion. A system of indicia has a non-recurring distribution about the exterior surface portion and is recessed within the wall portion. The system of indicia is scannable by an optical scanning system to provide unique scan body imaging information for constructing computerized models.

The present invention relates to a combination of configurations for copings and for the fiber bar for manufacturing a dental prosthesis framework, and describes a method for obtaining a dental prosthesis framework using one of the described copings and the fiber bar. The configuration feature applied to the coping is that of providing at least one incorporated hook to accommodate the fiber bar, withstand the stress on the framework and contribute to the adhesiveness of the fiber bar to the coping, also aiding in maintaining the molded shape of the bar whilst it hasn't polymerized. The feature of the fiber bar is that it can be produced from a bundle of parallel fibers that are longitudinally aligned, non-fragmented and covered by a woven glass-fiber jacket, there also optionally being a seam to ensure a flattened cross section.

A digital workflow process and associated devices and tools for providing dental restorations and, more particularly, to precise and efficient reconstruction and replacement of teeth using novel digital workflows and improved dental scan bodies, abutments and other dental devices and tools to efficiently achieve a more precise fit and optimal form and function.

An anatomical healing abutment is configured to connect to a dental implant. The healing abutment has a body portion which includes at least three reference marks that provide data to orient the connection axis of the abutment with the that of the dental implant so that certain conventional steps, including healing abutment manipulation, multiple scans, and the taking of impressions, can be eliminated, thereby saving time and effort on the part of the practitioner.

Various implant analogs and dental modeling techniques are disclosed herein. The implant analogs are versatile and can be used in traditional modeling techniques or in rapid-prototyping techniques for producing dental models.

An impression device for a dental implant includes an impression cap having a first connection opening extending along a longitudinal axis and a first connecting section, and a connector element for fixing the cap relative to the implant. An impression abutment has an abutment body having, on a first side, an end face to be attached to the implant and, on a second side lying along the longitudinal axis from the first side, a second connecting section for connecting to the first connecting section. The impression abutment further has a second connecting opening extending along the longitudinal axis and, in a fitted position, in which the impression abutment and the cap are attached to one another, aligned along the longitudinal axis with the first connection opening that the connector element can be guided through the first connection opening and the second connection opening for connecting to the dental implant.

Methods for taking a scan of a patient's oral cavity for use in fabricating a dental prosthesis. Such methods may include providing a healing cap configured to be received within a subgingival void of a given tooth position, taking a first scan of the healing cap, wherein the first scan is taken outside of a patient's oral cavity, seating the healing cap, taking a second scan, which is an intraoral scan of the healing cap and surrounding surfaces once the healing cap is seated, taken inside the patient's oral cavity; and integrating the first scan of the healing cap with the intraoral second scan of the healing cap and the surrounding surfaces into an overall oral cavity scan. A third scan, (e.g., 3D cone beam scan), can also be taken, which is overlaid or otherwise integrated with the first and second scans, for use in fabrication of a dental prosthesis.
