A system for reconditioning a dental implant in situ comprising a buffer member and a drive member. The buffer member is operable in an open configuration in which the buffer member may be placed over a portion of the implant and a closed configuration in which the buffer member is in contact with the portion of the implant. The drive member is adapted to engage the buffer member such that rotation of the drive member is transferred to the buffer member. Rotation of the drive member with the drive to member engaged the buffer member and the buffer member in the closed configuration causes rotation of the buffer member such that the buffer member abrades at least a portion of the surface of the implant.

Method for expanding bone crest and an implant-expander for use in said method

Номер: US20120082952A1
Принадлежит: BTI Biotechnology Insttitute

Method for expanding bone crest ( 1 ) in order to receive the installation of a final dental implant ( 4 ), where the bone crest ( 1 ) is expanded using a implant-expander, in other words, a biocompatible and osteoconductive piece that has an expander function. The use of an implant-expander ( 3 ) to widen the bone crest ( 1 ) has the important effect of said implant-expander acting as a support to the bone and therefore helping to consolidate the fracture of the bone crest ( 1 ) and the formation of bone around said implant-expander. The bone generated around the implant-expander ( 3 ) is therefore of a high quality. The invention also contemplates the optional correction of the angulation of the alveolus during the widening process, so that the final dental implant ( 4 ) and the corresponding dental prosthesis are adequately oriented. It is also an object of the invention to provide a specific design for the implant-expander ( 3 ).

In an exemplary embodiment, a method of creating an impression of structures of the human oral cavity comprises: preparing impression trays: creating a first, or base, impression; grinding out portions of the base impression; and using the void(s) in the ground out base impression to take a second, or wash, impression. The base impression is taken with an excess of a high-density impression material which is positioned to extend beyond the structures of interest (of which the impression is being taken). The base impression is removed and all fine structure surrounding the structure(s) of interest is ground out. A wash impression is then taken using a low-density impression material. The base impression creates a seal around the structure(s) of interest (a closed system), thereby producing omnidirectional hydraulic pressure on the low-density material. Such omnidirectional hydraulic pressure produces a highly detailed final impression from which a high-quality model (e.g., cast) can be made.
