The functional and aesthetic success of implant treatment in
the anterior zone depends not only on the quality of the prosthetic
restoration, but also on the contour, position, and stability of the soft
tissues. It is these tissues that conceal the implant neck and establish a
gingival level that is harmonious with the adjacent tissues. Nevertheless, in
the literature, marginal bone loss of 1.2mm to 1.5mm after implant placement
and loading is often considered unavoidable.
In the anterior zone, this phenomenon is responsible for
unaesthetic gingival recession that will undoubtedly occur in patients with
difficult, thin periotypes, and often in moderate periotypes as well. In
patients with favorable, thick gingival, limited marginal bone loss does not
necessarily have a negative effect on the aesthetic result. In the posterior
region, bone remodeling will increase the extrabony lever arm that can
jeopardize the longevity of the implant.
