Effect of macro-design of immediately loaded implants on micromotion and stress distribution in surrounding bone using finite element analysis.

Objectives: Macro-design influences the initial stability of implant and reduces micromotions. The aim of this study was to determine and compare micromotions and stress distribution in the bone around immediately loaded Maestro and Xive implants using finite element analysis.

Materials: In this experimental study, accurate, clear photos were prepared of Xive and Maestro implants 12 and 13 mm long and 4 and 3.
