Tilted Implants

Abstract

Introduction and aim: The authors discuss tilted dental implants. They define the tilted and the vertical implants, and they draw attention to biomechanical advantages, which the tilted implants bring.The first presumption of the effectivity of tilted implants is their high resistance to extra-axial occlusal loading. However, former papers based on photoelastic models, finite element analyses or clinical studies have proved this surprisingly high resistance. Results: Four indication groups are defined and they are illustrated by implantological cases. The most important indication of the tilted implants is the edentulous jaw in connection with the All-on-4 and All-on-6 concepts. Conclusions: The authors reveal that there is not any reason for the insertion of the vertical implants. The rationally disparallel implants are more effective. However, this trend is not followed enough in the Czech implantological practice. A definitive evaluation of the effectivity of the tilted implants will be provided on the basis of long-term clinical experience.
