A dental cleaning system includes a cylindrical body with a first portion and a second portion. A cleaning portion is positioned within the second portion and includes a cavity to enable the cleaning portion to at least partially enclose a dental implant device. The cylindrical body rotates such that the cleaning portion therein rotates to clean at least a portion of the dental implant device. A projection extends outwardly from a surface of the cleaning portion such that the projection is positioned within the cavity. The projection removes debris from at least a portion of the dental implant device when the cylindrical body rotates. A plurality of cleaning protrusions extend outwardly from a sidewall of the cavity such that the cleaning protrusions at least partially circumscribe the projection. The cleaning protrusions remove the debris from at least a portion of the dental implant device when the cylindrical body rotates.

A dental implant having a central longitudinal axis at a bone-entry portion thereof is provided. The dental implant includes a threaded elongate fixture, at the bone-entry portion of the dental implant, shaped and sized for insertion into a bone of a subject, and a non-threaded emergence collar coronal to the fixture and smoother than the fixture. The emergence collar has a non-circular cross-section at least in a plane that is at least 1 millimeter coronal to the fixture and that is perpendicular to the longitudinal axis, the emergence collar and the fixture being formed of, and adjacently disposed along, a single piece of metal. Other applications are also described.

Apparatus and method for installing a multi-tooth dental prosthesis in one session are shown and described. A first tool attaches to the jawbone, and serves as a foundation for subsequently used guides. Existing teeth and dental fixtures are removed, and the bone tissue is removed to accommodate the prosthesis. Subsequently, a drill guide is used to drill implant holes. An abutment guide is then used to place abutments. Copings are then installed. Next, the prosthesis may be installed and cemented to the copings. A resinous filler material may be applied to fill gaps and holes in and between the copings and the prosthesis, and is sanded smooth.

One aspect of the invention concerns an overdenture retention implant (10) comprising an externally threaded implant body (12) to be screwed into a hole formed in a jawbone (70) and an implant end structure (14) at a proximal end of the implant body. The implant end structure includes a tool engagement portion (14.1) that can be engaged by an implant installation apparatus operable to rotate the implant to screw the body into the hole, and a threaded boss (14.2) to be engaged in threaded manner by an overdenture retention cap (100) configured for attachment of an overdenture. The tool engagement portion and boss have a common, central axis (22) which intersects the central axis (20) of the implant body at an acute angle (24). Other aspects of the invention concern the combination of the implant (10) and installation apparatus and the installation apparatus itself.

The invention provides a dental prosthesis, comprising: an implant frame configured to be fixed into the mouth of a patient to support replacement of two or more teeth of the patient, the implant frame having an exterior surface, the exterior surface defining a first engagement profile; and an overlay adapted to be secured to the implant frame and to provide, or afford mounting of, the two or more teeth, the overlay having an internal cavity that extends along a substantial length of the overlay, the internal cavity defining a second engagement profile, wherein the second engagement profile is complementary to the first engagement profile, thereby allowing fitment of a substantial portion of the exterior surface of the implant frame within the internal cavity.

A dental abutment comprising a cylindrical abutment body and a tubular reconstruction element support; the abutment body is couplable to a dental implant and comprises a flat support end, the reconstruction element support has a proximal anchoring head portion configured with at least one slot, and a distal seat end bearing flush against the flat support end of the abutment body, said reconstruction element support is further configured with an axially extending through-going head bore, whereby the reconstruction element support is coupled to the abutment body by a manipulating fastener extending through the bore, and wherein axial fastening the fastener entails radial expansion of the anchoring head.

The present invention relates to a dental object (100), comprising an adhering region (103) for attaching the dental object (100) to a tooth, teeth (105) or the gums, comprising an array (101) of suction cups (107-1, . . . , 107-n).
