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.
