coefficient of friction the effect of friction can be superimposed on
the interfacial shear strength caused by interlocking. The same
applies to adhesion.
To optimize the interfacial shear strength for a given situation,
all parameters addressed in this study need to be considered. The
dentist needs to know the quality of the bone and relate that to
the design of the implant. An optimization of bone support,
implant size and wall thickness must be made irrespective of
the surface roughness.
