IPHE - Fatigue Test

The fatigue limit of the ”MPI Privilege Implant of External Connection” has obtained a value of 204 N, respecting the geometric arrangement shown in ISO 14801:2007.

Due to the value of the diameter, these implants testes will only be used in lower incisors and upper lateral incisors. Scientific studies have demonstrated that chewing forces with natural teeth in that areas vary between 5 and 54 N. (Gay et al., 1994, Dan et al., 2003; Kohyama et al., 2004a, 2004b, 2005; Johnsen et al., 2007, Xu et al., 2008).

Tests conducted by the Institute of Biomechanics of Valencia thus conclude, that the ”MPI Privilege Implant of External Connection” exceed the fatigue limit to which natural teeth are exposed.
