Treatment planning in dental implantology Bucco-lingual evaluation 2

There are some important observe in bucco-lingual evaluation

Implant platform position related to median center of the bone crest;

Implant angulation related to implant platform.

An implant platform extremely positioned to the buccal can generate and emergence profile more apical than that of the adjacent teeth, or a secondary gingival recession due to the lack of bone support (commonly seen in the thin-scalloped periodontal biotypes).

This happens in immediate implant placement when the extraction socket is used as surgical guide.

On the other hand, an implant platform positioned to lingually will generate prosthetic overcontouring, which inhibits adequate oral hygiene. Also, screw loosening and cement dissolution can occur. In both cases, occlusal forces are unfavorable.
