Abstract: A one piece screw type mini dental implant (20) with a supragingival comfort head (10) that is generally frustoconical in shape and smooth in contour and outline, with rounded edges (11). The diameter of the base (12) is bigger than the diameter of the screw portion (1) by a factor of 1.5 to 1.6. Flats (4, 6), facets (5, 9), through holes (8, 8?), slots (7, 7?), and/or grooves (13, 13?) may be provided on the supragingival head (10). These features provide a mini dental implant that feels comfortable in a patient's mouth, is easy to place, amenable to direct impression taking and applicable in prosthodontic and orthodontic use.

Abstract: A prosthesis mounting device (30) for mounting onto mini dental implants (50), of generally frusto-conical shape with an axial recess (20), which base (21) has overhang (33) over the collar (34) of a mini implant (50). Together with a two stage cement removal process this provides a prosthodontic solution to the problem of excess cement removal in mini implant fixed restorations. When an annular groove is provided at location (6) and anti rotation means (not shown) is provided on the external wall (19) the prosthesis mounting device (30) can function as a denture attachment device. A carrier tool (80) to enable easy handling in the mouth is also provided.

Abstract: A metal/plastic housing useable for releasable denture attachment to an o-ring abutment of a dental implant, within which an elastomeric o-ring is seatable, wherein the elastomeric o-ring is an elastomeric orthodontic o-ring.
