Dental Implant therapy has been a predictable treatment modality in long term studies. Nevertheless, the predictability of anterior dental implant esthetics has always been a challenge for the long term results.
Since the alveolar bone around implant platform area constantly shows bone resorption of approximately 1.5 mm in depth and 1.4 mm in depth after function, the recession of gingiva around the implant occurs.
It is possible that we can maintain the alvoelar bone. There are differences among implant systems, regarding bone resorption. Implant designs cause different degrees of bone resorption. Implant and abutment design create differences in anterior esthetics.

It all depends on choosing the right dental implant system for a particular case.
