Treatment planning in implantology Bucco – Lingual evaluation

In the bucco-lingual dimension, the retention mechanism proposed (screwed or cemented) must be considered. as an example, for cemented prostheses, the implant long axis must coincide with the tooth long axis.

On the other hand, the implant must coincide with an imaginary point between the incisal edge and the cingulum. Variations on these culminate into mal-positioned implants.

Two aspects must be considered here: the implant must be surrounded by at least 1 mm of healthy bone tissue and be positioned at the center of alveolar ridge due to biomechanical factors.

The implant must favors the crown’s emergence profile. However, an accentuated osseous concavity in the apical-coronal direction will force the implant to be inclined bucally. Thus, the clinician must find a “compatibility region”, otherwise, new planning for hard tissue surgery will be necessary to satisfy esthetic demands.
