The invention relates to an adaptor system for a dental prosthesis. The adaptor system comprises an abutment and an adaptor, wherein said adaptor is adapted to connect to a prior art or new implants and is also connected to the abutment by a rotational connection. The adaptor and the abutment are secured to the implant by a screw that retains the angular position of the abutment.

The invention is directed to a new dental implant and associated parts that allow for insertion in narrow areas of the alveolar bone. Characteristics of the body of the implant allow for comfortable insertion in narrow bone clefts provided by its smooth narrow sections. The implant provides an alternative to complex and time consuming surgical processes involving bone regeneration and/or grafting.

The present invention relates to a prosthetic assembly (1, 10, 100) comprising a prosthetic component (2, 20, 200) and a retention screw (6, 60, 600) with an interference geometry (5, 50, 500) designed to allow relative rotation, limit relative longitudinal motion and inseparably join the prosthetic component (2, 20, 200) and the retention screw (6, 60, 600). The interference geometry (5, 50, 500) can be in the form of a ring attached to the retention screw (6) in a portion of the body of this screw (6) having a smaller diameter, or in the form of one or more inwardly folded flaps integrated in the prosthetic component (20) and diametrically distributed around the base thereof, or in the form of a uniform, tapered and hollow projection of the lower portion of the prosthetic element (200). The invention further relates to a method for producing the disclosed prosthetic assembly (1, 10, 100), including the following steps: forming a prosthetic component (2, 20, 200) having a central hole (8, 80) for receiving the retention screw (6, 60, 600), forming a retention screw (6, 60, 600), the body of which has a portion having a smaller diameter (62, 602), inserting the retention screw (6, 60, 600) into the central hole (8, 80) of the prosthetic component (2, 20, 200), and forming an interference geometry (5, 50, 500) between the base of the prosthetic component (2, 20, 200) and the body of the retention screw (6, 60, 600).

Dental implants, dental abutments, and dental systems are disclosed. A dental implant can include an implant body having a longitudinal axis, a coronal end, and an apical end. An internal bore can be provided within the implant body, and can have a coronal end, adjacent to the coronal end of the implant body, and an apical end. The internal bore can include a first internally facing surface, extending from the coronal end of the internal bore towards the apical end of the internal bore, at least a portion of which tapers inwardly towards the apical end of the internal bore. The internal bore can further include an internally threaded portion positioned between an apical end of the first internally facing surface and the apical end of the internal bore. A dental abutment can be configured to engage with the dental implant.

A dental anchoring system includes an angled abutment, having a main body extending from a top to a channel body, the channel body extending away from the main body at a predetermined angle less than 180 degrees; a lip extending around the top; and an opening extending from the top and through the channel body, the opening to receive an attachment device; the angled abutment is to provide an angled attachment for a dental prosthetic.

Disclosed herein is a cleaning system (30) for a dental implant part (2) that has been introduced into the jaw bone of a patient. For this purpose, in an advantageous embodiment of the invention, a securing element, which is adapted on the end side to connect to a corresponding connection element in the dental implant part, particularly preferably which can be screwed into a thread of the dental implant part by the end side, and to which a distribution element for a cleaning fluid as well as an electrical contact element can be attached, which distribution element can be connected to an external media reservoir via a media channel, and via which electrical contact element, a power source that is connectable to an external power source can be electrically connected to the dental implant part.

A convertible dental assembly is disclosed herein. The convertible dental assembly includes abutments adapted for fixing with implants; fixed-hybrid housings adapted for fixing with the abutments through a fixing screw; and removable-hybrid housings, adapted for engagement with abutments through snap fit parts. The fixing screw and the snap fit part are fixed to the abutments through same female threads on the abutments. The fixed-hybrid housings are used for a fixed-hybrid dental assembly during period of healing of the implants, and replaced by the plurality of removable-hybrid housings along with the snap fit parts for a removable-hybrid dental assembly after the period of healing of the implants. The fixed-hybrid housings and the removable-hybrid housings can be captured in the dental assembly via chair-side pickup at respective instances. The removable-hybrid housings can be placed indirectly by a dental laboratory if a new denture is being fabricated. The abutment includes an outer frustoconical profile that engages with matching frustoconical cavities in the fixed-hybrid housings and removable-hybrid housings.

A System of Triple abutments with Tconnect comprising T-abutments to place at least three dental crowns over a one only osseointegrated implant and only one T-abutment, for partial fixed cases and new total fixed segmented cases, T-Over abutments with Plug T for use of overdentures over only one abutment and only one osseointegrated implant too, T-healing for guide specific gingival contour of the Tconnect in the healing phase and T-guides, to guide the implant surgery to be positioned for the use of abutments of this system. The all abutments of this system has Tconnect, being an exclusive design support with paraboloid multidimensional contour in double shape curvature with three pins disposed in the form of a tripod (in triangular arrangement) and are adaptable to all the implant/abutment fitting connections of market. All system may be individualized, make in process type CAD-CAM or prefabricated (manufactured type) and it can receive any type of surface treatment. The new biomechanical possibilities of the invention provide stability, passivity, greater precision of adaptation and better distribution of tensions, a fundamental advantage for use of the immediate load. The soft tissue is favored by immediate loading too. The new fixed arrangements with segmentation promotes cleaning and longevity for the system. This invention provides superior resistance of the abutments, long-lasting esthetic and reduction of the bone grafts, clinical time and costs, ensuring predictability of the results.

Disclosed is an implant fixture. The fixture of a dental implant according to the present invention includes a fixture body in which a screw portion is formed in a spiral shape along an outer wall and an abutment insertion groove inserted with an abutment is recessed in a longitudinal direction at an upper end, an abutment rotation stopping portion which is formed in a shape in which at least a part of the inner wall of the fixture body is shape-fitted to the outer wall of the abutment and stops a relative rotation to the fixture body of the abutment, and a tool coupling portion which is provided in the fixture body adjacently to the abutment rotation stopping portion in an upper region of the abutment rotation stopping portion and detachably coupled with a rotary tool rotating the fixture body.
