Stress analysis of a single prosthesis on a poorly positioned implant
Reis, Francisco Carlos dos Santos; Brandt, William Cunha; Boaro, Letícia Cristina Cidreira; Miranda, Milton EdsonThe mechanical positioning behavior of a mal-positioned implant was evaluated in the finite element method. Models were created in SolidWorks Professional 2013® software with a single implant rehabilitation. The following were analyzed: Control Group, crown aligned to the implant long axis; Experimental Group, crown shifted 3 mm mesial proximally to the implant axis. Compressive stresses in cortical and medulla...
