AN EXPERIMENTAL-ANALYSIS OF THE STRESSES ON THE IMPLANT IN AN IMPLANT-TOOTH-SUPPORTED PROSTHESIS - A TECHNICAL NOTE

When a natural tooth connected to an implant abutment by a framework i s displaced within physiologic limits under functional loads, the supe rstructure acts as a cantilever moment arm and the implant is loaded a dditionally during that moment effect. The effects of a deflecting sup port connected to art IMZ implant, with either the IMC resilient or th e titanium rigid element, were evaluated through an experimental model . The strain values measured when the moment arm was not allowed to de flect were only 30% lower than the strains measured when it was deflec ted within the limits of physiologic tooth mobility. The IMC was effec tive and achieved a reduction in the cervical strains up to 60% when c ompared with the rigid connector.
