Total displacement of the thirteen implants were analysed with 45 N for the reason of
the large variety of the obtained forces. The displacements and rotations were measured
at the mid of the uppermost part of the abutment.
The largest displacements were observed with MDI Hybrid TM implants 2.9x10 mm (194
µm, Figure 8) followed by K.S.I.-Bauer Schraube implants (141 µm for 3.0x18.5 mm,
and 133 µm for 3.0x15 mm).
