The invention relates to a dental interphase with a mode for the reversible fitting of a prosthetic structure to a dental implant comprising an expander core (2), an activator screw (3) and a connection element, wherein the activator screw (3) incorporates an external thread (31) for being attached to the expander core (2) by screwing onto an internal thread (22) in the area of notches (23) to a specific depth, the connection element being intended for being coupled to the expander core (2) by attaching a coupling area (14) incorporated in a complementary coupling area (24) incorporated in the expander core (2) such that, once the activator screw (3) is inserted into the expander core (2) the attachment of the interphase to the implant (6) may be permanent, or it may be reversible, where it can be taken apart.

A dental restoration system is disclosed. A dental restoration system includes an implant, retention component, dental component and driver tool. The retention component is seatable in a retention chamber of the implant. The retention component includes a driver section for interfacing with a driving head of the driver tool and a dental component engagement section with a threaded surface. The dental component includes a retention component interface surface with threads. The dental component engages the retention component via the threaded surface interlocking with the threads of the retention component interface surface when the dental component is inserted in the implant. The driver tool is used to rotate the retention component to engage the dental component apically. The retention component contacts the retention component wall and the dental component contacts an annular shoulder of the implant when the dental component is fully attached to the implant.

A dental prosthesis (100) for anchoring in the jawbone (1), comprising a dental implant (110) with an implant body (111) and an abutment (112), a tooth part (120) with an internal guide (122) in the tooth part (120), in particular penetrating the tooth part (120), and a closure body (130) for sealing the dental prosthesis (100) within the internal guide (122) in the tooth part (120), in particular penetrating the tooth part (120). A connecting sleeve (140) is arranged between the closure body (130) and the internal guide (122) of the tooth part (120), by means of which connecting sleeve the tooth part (120) and the dental implant (110) can be connected to one another indirectly, detachably and/or by means of which connecting sleeve the closure body (130) can be releasably locked within the internal guide (122) in the tooth part (120), in particular penetrating the tooth part (120).

A tool assembly for mounting a dental abutment includes a first tool, the first tool having an axis of elongation, a first end configured to engage, in use, the abutment, and a second end, where a first portion of the first tool at or near the first end has a peripheral wall and, opposite the wall, a first opening extending along all or part of the first portion, a second opening open in an axial direction is disposed at the first end, the tool assembly further including a second tool configured to releasably engage a fixing element, where a contiguous space is defined between the first opening and the second opening whereby, in use, the fixing element, or the fixing element attached to the second tool, may pass through the first opening and the second opening to permit secure fixing of the abutment to an implant or frame using the second tool.

Dental blank for the production of a dental prosthetic restoration, in particular of a multi-coloured dental prosthetic restoration, by processing removing the outer region of the blank, comprising (i) an inner connecting element having an preferably peg-shaped scaffold region in the direction of the coronal region of the dental blank and an implant connection geometry in the radicular direction of the dental blank, (ii) wherein the scaffold region of the connecting element is connected to a dentin scaffold region in the direction of the coronal region of the blank, and wherein (iii) the dentin scaffold region is connected to an (iv) outer region of the blank in the region of enamel in the direction of the coronal region of the blank, and wherein (v) the dental blank has an inner elongated lumen for fastening of the produced dental prosthetic restoration on an implant or abutment by means of a connecting screw or a bolt. Moreover, a subject matter of the invention is a system for the production of a dental blank as well as the method for the production of the blank.

A system, device and method for restoring the use of a damaged dental implant. The system, device and method utilizes a dual thread fixation screw capable of coupling an abutment or abutment assembly to the damaged dental implant, therein rescuing the damaged dental implant.

A set of components for dental prosthetic restoration includes a ceramic dental implant having an internal connecting receiving space. An internally threaded insert is added into the internal connecting receiving space of the dental implant, and rotatably indexed. It is held by a fixing part forming an axial abutment opposing an extraction of the internally threaded insert out of the inner connection receiving space.

The present invention relates to a dental implant (100, 100′, 500) and to a kit for said dental implant. In order to provide dental implants (100, 100′, 500) which meet the general requirements for a successful implantation and use and which can be easily adapted to bone variations and implant offerings, it is proposed according to the invention that the dental implant (100, 100′, 500) comprises a ceramic base body (130, 530), a ceramic abutment (120, 120′, 520), a ceramic tooth structure (110), and/or a connector (1, 1′, 1″, 5) for connecting of base body (130, 530), abutment (120, 120′, 520) and/or tooth structure (110) to each other, and a bushing body (6), which is at least in a final assembly state (E) of the dental implant (100, 100′, 500) received at least partly in the base body (130, 530), in the abutment (120, 120′, 520) and/or in the tooth structure (110) or surrounds the connector (1, 1′, 1″, 5) at least in sections.

Molds for fabrication of custom and potentially modifiable abutments and impression posts for dental implants with various degrees of angulations (including zero degrees) and various dimensions are provided, with a generally oval shape that expands laterally upwards, a symmetrical or asymmetrical cross-section, and regular surfaces, that are fabricated as one piece, or as two coupling pieces snapping onto each other. Custom abutments achieve the development of a custom gingival emergence profile, three dimensionally, which is potentially modifiable according to the needs of each particular clinical case. Custom impression posts that correspond in dimensions and angulations to the abutments allow the accurate recording and transfer of the developed gingival emergence profile from the mouth onto the working cast, where the final implant prosthesis is fabricated. Custom abutments and impression posts have properties and design that allows their preparation and usage as temporary abutments for the cementation and support of temporary prostheses.

An improved fixing pin support for a dental prosthesis in order to be able to connect the dental prosthesis to a jaw by means of fixing pins which can each be moved through a guide bore in the fixing pin support. The improved fixing pin support has a guide sleeve separate from it which can be temporarily fitted over the fixing pin support so that the guide bore can be formed in the fixing pin support through a guide channel in the guide sleeve, by precise guidance of a drill. After this, the guide sleeve can be removed from the fixing pin support.
