Implant–Bone Interface Stress Distribution in Immediately Loaded Implants of Different Diameters: A Three‐Dimensional Finite Element Analysis

Abstract: With an increase of implant diameter, stress and strain on the implant-bone interfaces significantly decreased, especially when the diameter increased from 3.3 to 4.1 mm. It appears that dental implants of 10 mm in length for immediate loading should be at least 4.1 mm in diameter, and uniaxial loading to dental implants should be avoided or minimized.

“…The biomechanical aspects play an important role in the techniques related to implants in bones and many research have been per-formed, in particular by using experimental investigations and by developing computational mechanical models for understanding the aging and the implants stability as a function of the geometric shape and of the dimensions of implants (see for instance [2,4,9,17,19,32,37] and also [44,49,58,60,71,78,92,95]). Design optimization of implants in bone at macroscale by using deterministic computational models has also received increased attention (see for instance [36,43,50,53,56,74]).…”

“…A maior concentração das tensões estão localizadas na região da crista óssea, que corresponde ao osso cortical (Deines et al, 1993;White et al, 1994;Ichikawa et al, 1997;Cruz et al, 2003;Assunção et al, 2009;Ding et al, 2009) e na interface osso cortical e trabecular Baggi et al, 2008), porisso, deve-se levar em consideração o desenho de rosca utilizado nestas regiões.…”

“…Além do formato dos implantes, do tipo de prótese utilizada, a incidência e intensidade das tensões, também foram padronizadas, Estudos mostram que implantes submetidos às excessivas cargas oclusais, acarretam perdas ósseas (Deines et al, 1993;Itoh et al, 2004;Ding et al, 2008;Canay;, Ding et al, 2009Qian et al, 2009;Guan et al, 2010;Pellizzer et al, 2010) , principalmente na região cervical (White et al, 1994).…”
