The present invention relates to a method for manufacturing a tooth prosthesis, for insertion in a jawbone, including an implant and an abutment on top of the implant. The method includes: defining a shape of the prosthesis and its location in the jawbone by using first data from a first CT scan image of the jawbone and second data from a second image of a gypsum cast, correlating first and second data by extracting from the first data first position reference data of a first reference in the first image, and from the second data second position reference data of a second reference in the second image, the second reference being identical to the first reference; performing a geometric transformation on the second data and / or the first data to have a coincidence of the second image with the first image and to combine the first and second data into composite scan data.

An implant comprising 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.

The invention relates to a dental implant abutment, in particular relates to an abutment internally connected with an implant, and belongs to the fields of oral implant and repair. The connecting abutment consists of a crown connecting section, a middle trans-gingival section and an implant insertion section sequentially from top to bottom. The upper crown connecting section of the connecting abutment is a downward enlarged cone of which the taper is 6 degrees. A vertical cutting groove is formed in each of two lateral surfaces of the upper crown connecting section of the abutment, and the two cutting grooves are symmetrically distributed on the two lateral surfaces. The abutment can be used for positioning a crown, and plays a role in resisting rotation. A conical transition section is arranged between the abutment and a connector, and a silver-carrying TiO2 antibacterial coating is coated on the surface.

In case of straight driver, the entrance of screw inserting hole of implant prosthesis is on the same line with implant fixture's axis. Due to this position of the hole, final prosthesis has many difficulties. Thus. the free angled driver(301) is invented. For maxillay anterior teeth, we can move the screw hole to ligual surface of prosthesis(511). We can make esthetic and convenient prosthesis with capability of easy screwing and unscrewing. Also. I invented the free angled hole abutment(300) for the free angled implant driver,so we can move occlusal hole to the ideal position. It is an epoch-making change to solve many problems in the contemporary dental implant prosthetics.

An immediate dental implant shell has outer, multiple zones for engaging a soft tissue socket left immediately after tooth extraction from a bone socket. The zones have combinations of different biologic agents, macro- or micro-geometric, or micro- or macro-morphology irregularities to better engage gingival sulcus, junctional epithelium and dento-gingival fiber zones of the soft tissue socket. The shell may also have various guide markings and projections to aide drilling of the implant hole in the bone socket. A dental implant is placed in the drilled implant hole before or after the shell has been placed in the soft tissue socket, and has an axis that is independent of the shell axis so the shell and implant both sit in optimum positions in their respective soft and bone sockets.
