SALES E PESSOA, Roberto et al. Influence of implant design on the micromovement of immediately placed and loaded implants: a multivariate finite element analysis. Innov. Implant. J., Biomater. Esthet. (Online) [online]. 2010, vol.5, n.1, pp. 44-49. ISSN 1984-5960.

The purpose of this paper was to evaluate the influence of different implant designs on the micromovements of immediately placed implants. CT-based finite element models comprising an upper central incisor socket and four commercially available internal connection implant designs (SIN SW^®, 3i Certain^®, Nobel Replace^TM, and RN synOcta^® ITI Standard) of comparable diameter and length were constructed. 50, 100 and 200N magnitude loads were applied over the implant. ANOVA at 95% level of significance was used to evaluate bone to implant relative displacement (micromovements). The implant design (68,80%) greatly influences the micromovement of immediately placed implants. However, the loading magnitude (68,80%) is the most important factor regarding the implant stability in this protocol.
