Implant placement in the aesthetic
area: key factors for long-term success
Implant placement in the aesthetic area: key factors for long-term success
The alveolar process is a tooth-dependent structure that inevitably undergoes
dimensional alterations following tooth extraction.
The buccal bone wall resorbs more than the corresponding lingual/palatal one
and the resorption is most pronounced at the central aspect. Therefore, lack of
buccal convexity is a common finding following tooth extraction.
This so-called “alveolar process deficiency” may compromise the aesthetic
outcome of single implant treatment. As a result, contour augmentation by
means of guided bone regeneration (GBR) is required in the vast majority of
cases with aesthetic priority.
This procedure can be predictably performed following soft tissue healing,
being 4 to 8 weeks following tooth extraction. In this presentation the biologic
and biomaterial background of this well-documented technique is discussed.
In the second part of the lecture a step-by-step approach is presented and the
clinical applications of GBR are discussed in detail.
