Narrow-Diameter Implant Versus Lateral Bone Augmentation : What are the Evidences ?

Abstract

For optimizing functional and esthetic implant therapy results, sufficient bone amount is required at the reception site. A reduced buccolingual ridge dimension may not allow the placement of a standard-diameter implant without the risk of implant thread exposure. In such situations, lateral bone augmentation procedures can be performed that would allow a restorative-driven placement of standard-diameter implants. Conversely, the use of narrow-diameter implants (diameter ≤ 3.5mm) could be another predictable solution to avoid any invasive surgical management. The aim of this review is to analyze the survival rate of narrow-diameter implants as well as the effectiveness of different techniques for lateral bone augmentation in improving implant clinical outcomes.
