A temporary cylinder for snap-in retention with an elongate dental implant includes an elongate body extending from a first end to a second end, the elongate body being generally cylindrical and having an upper portion and a lower engagement portion and the temporary cylinder's lower engagement portion includes a male irregular hexagonal plug, and wherein the dental implant includes a female regular hexagonal socket, and wherein the male irregular hexagonal plug and the female regular hexagonal socket are configured for inter-engagement with each other, and the fitment of the irregular hexagonal plug and regular hexagonal socket together with one another results in a frictional fit when inter-engaged.

A hybrid temporary anchorage device implant system and method of use is disclosed. A temporary anchorage device (TAD) implant includes an external hex head, a cupped inner portion, a threaded core, a platform, and an implant portion. A first abutment is installed on the implant portion. The first abutment may include a graduated portion, a screw-retained healing collar, and a threaded portion. A second abutment may be installed over the first abutment. The second abutment may include a graduated head, a bulbous base, and an inner canal.

A system for fabricating a dental restoration to restore a tooth at a restoration site in a dentition of a patient is disclosed. The dentition includes a restoration dental arch and an opposing dental arch. The restoration dental arch include the restoration site and the opposing dental arch is opposite the restoration dental arch. The system includes an impression apparatus, a motion capture apparatus, an interface apparatus, and a restoration design system. The impression apparatus is configured to capture an impression of the dentition of the patient. The motion capture apparatus is configured to capture a plurality of location data points that represent the locations of the opposing dental arch relative to the restoration dental arch. The interference model generation system is configured to generate an interference model for the restoration site. The restoration design system is for designing a restoration using the interference model.

Disclosed is a bone screw for 3D guided bone regeneration used in dental surgery for inducing and regenerating a part of alveolar bone defected in or around an implant surgery region. The bone screw includes: a head portion configured to provide a tenting function for a part of the alveolar bone to be regenerated or induced; a neck portion formed on a lower surface of the head portion; a screw portion formed beneath the neck portion and directly fixed to the alveolar bone in a thread fastening manner, wherein the alveolar bone can be induced or regenerated three-dimensionally. Since osteoinduction is promoted three-dimensionally to grow the alveolar bone rapidly by filling the bone graft, it is possible to shorten a period of the dental implant surgery procedure.

A dental implant evaluation unit is disclosed and described. The dental implant evaluation includes a body portion having threads that mimic the general thread pattern of an actual dental implant, without attempting to copy any of the osseointegrative features of the actual implant. A threaded collar is associated with the body portion, and, in certain embodiments, a safety flange is screwed to the threaded collar. The safety flange prevents the dental implant evaluation unit from infiltrating the sinus of a patient when testing the fit of a maxillary implant. The dental implant evaluation unit can be used by a dentist to evaluate the proper size and fit for an actual dental implant by installing the dental implant evaluation unit, and imaging the same, prior to installing the actual dental implant.

An implant includes two internal anti-rotational features. One anti-rotational feature is adapted to engage a driving tool, while the other anti-rotational feature is adapted to engage an abutment. An implant abutment system is provided with an angled abutment adapted to mate with one of the anti-rotational features. A second, straight abutment is adapted to engage with the other anti-rotational feature. An abutment is provided with resilient fingers to interface with the implant and provide tactile and audible feedback indicating when the abutment is properly seated. An abutment screw extends through the abutment and engages the implant bore distal of the stem of the abutment. The abutment screw limits axial movement of the abutment relative to the implant. A driving tool includes one of at least retention structure and visual alignment indicia is provided to facilitate screwing the implant into a patient's bone.

A radiographic guide that can be used as a surgical guide is provided. The radiographic guide uses a provisional dental implant instead of a denture tooth or a custom made diagnostic tooth. The provisional dental implant, which can be integrated or selectively interconnected to the radiographic guide, may have a through-hole or a tapped hole that facilitates location of a dental implant. If the planned implant location is acceptable, the radiographic guide can be used as a surgical guide, wherein the hole guides surgical tools used to modify a patient's maxilla or jaw so it can receive the implant.

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 system for fabricating a dental restoration to restore a tooth at a restoration site in a dentition of a patient is disclosed. The dentition includes a restoration dental arch and an opposing dental arch. The restoration dental arch include the restoration site and the opposing dental arch is opposite the restoration dental arch. The system includes an impression apparatus, a motion capture apparatus, an interface apparatus, and a restoration design system. The impression apparatus is configured to capture an impression of the dentition of the patient. The motion capture apparatus is configured to capture a plurality of location data points that represent the locations of the opposing dental arch relative to the restoration dental arch.
