The vertical positioning of the implant in the alveolar ridge
should be considered differently. While until recently a relatively
high position was displayed to compensate for the formation
of the biological width with the resulting bone loss, which was
considered the main reason for facial tissue loss, now the principle
of “platform-switching” offers new options. The possibility
of using single-component implants as a replacement, which
was considered the solution for many problems, has proven
to be too sensitive to technique and less flexible and has not
become standard practice. Both the Ankylos and the Xive
systems allow platform-switching. This can prevent formation
of the biological width and the resulting loss of facial bone
and soft tissue over the long term.
New trends have also appeared in the shape and material of
the abutment. The original concave emergence shape adapted
to the shape of the tooth has been replaced by a convex or
multiple in-drawn shape that stabilizes the soft tissue as a
result of some interesting studies. These shapes are designed
to improve the gingiva trophic to the outer areas, because an
