An assembly for aiding field use of an endoscopic probe is disclosed. The assembly includes a housing assembly for an endoscopic probe and a compatible holder for the housing assembly. The housing assembly includes a tubular conduit for receiving the endoscopic probe and a plug coupled along a distal end of the tubular conduit. The holder includes a pre-configured arm for facilitating an exploration of a pre-determined quadrant of an oral cavity. The explorer includes a plug receiver. Upon coupling the plug receiver with the inversely matching plug, the tubular conduit passes through the opening and into the third axial channel.

An apparatus for installing a dental prosthesis. The apparatus includes a guide stent having one or more apertures. One or more implants have a tip and an abutment end connected by a body. A bridge prosthesis has one or more bores defined therein. A retaining fixture is disposed in the bore of the prosthesis. The bridge prosthesis is attached to the one or more implants via engagement between the abutment end of the implant and the retaining fixture.

A three-point locating dental implant locating guide and a three-point locating modeling method are disclosed. The three-point locating dental implant locating guide includes a first plate and a second plate that are pivotally connected. A first locating hole is defined in the first plate. A second locating hole is defined in the second plate. A third locating hole is defined in the junction of the first plate and the second plate. Extending directions of the first locating hole, the second locating hole and the third locating hole are arranged parallel to each other. Through the first locating hole, the second locating hole and the third locating hole, a positioning locating can be guided and implanted respectively, thereby forming a three-point locating as the modeling base for producing a dental mold accurately.

Embodiments of the disclosure relate to implantable objects and guiding devices, as well as recipient site preparation instruments, bone-implantable materials, and methods of fabrication and use thereof.

Provided is a non-incisional dental implant surgical method, and more particularly, a non-incisional dental implant surgical method using a guide pin, whereby a dental implant surgery may be conducted accurately by easily determining an outer shape of an alveolar bone of a patient, into which an implant fixture is to be placed, when forming an implant hole in the alveolar bone and placing the implant fixture in the implant hole to place an implant in the alveolar bone of the patient.

The present invention relates to a dental implant and a replacement ring. The dental implant has an insertion portion for anchoring in a jaw bone. The replacement ring serves for replacing a subtractively removable annular material region in a coronal region of the insertion portion. The shape of the replacement ring is inscribable into the shape of the dental implant in the coronal region at least to some extent such that an inner lateral surface of the replacement ring lies within the shape of the dental implant.

A system and method of automated formation of a preparation stub, based on an a priori created computational geometrical model, configured to conform to a prefabricated fixed dental prosthesis, is described. The system includes a digital imaging facility with an image acquiring device and a three-dimensional data digitizer, a modeling facility with an exterior surface design module and an interior surface design module, a fabrication facility operatively with a computer-aided manufacturing module, as well as an application facility including an ablation tool and in-situ preparation module; application facility preferably includes an intra-oral feedbacking appliance with a distance measurement probe for automated feedback-controlled formation of a preparation stub.

The present invention relates to a dental device (1) for removing a dental implant (2) which is at least partially or fully osseointegrated with a patient's jaw (3), comprising: a head portion (6) for rotatingly holding a dental tool (7) for unscrewing the dental implant (2); and a driving means for applying a torque to the dental tool (7) for unscrewing the dental implant (2); characterized in that the driving means is further adapted to apply pulsed torques (τ; τ.sub.1, τ.sub.2, τ.sub.3) to the dental tool (7) to unscrew the dental implant (2).

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.

Dental instrumentation for use in guiding a cutting tool to remove tooth structure from a working tooth is prepared. A digital model of cutting guide shell structure for placement around a portion of the tooth to be treated is combined with preset tool movements to be made by the cutting tool by one or more processors to define final cutting guide data corresponding to final cutting guide structure for guiding the cutting tool. A digital model of a fixation instrument configuration for fixing the dental instrumentation to an adjacent tooth to the working tooth is combined with the final cutting guide data by one or more processors to define final instrument configuration data corresponding to a final instrument configuration for releasably fixing the dental instrumentation to the adjacent tooth and for guiding the cutting tool in the removal of the tooth structure from the tooth to be treated.
