Effects of Vertical Interarch Space and Abutment Height on Stress Distributions: A 3d Finite Element Analysis


Abstract - This three dimensional Finite Element Analysis study investigated stress distribution and intensity in implants restored with cemented or screwed crown. Two parameters varied: interarch space and abutment height. Highest stresses occurred at the cervical area in all models. Stresses increased mainly with vertical interarch space highness, and secondarily with abutments shortness. From a mechanical point of view, bone and prosthetics components supporting cemented crowns were not as solicited as with screwed crowns.

KEY WORDS: biomechanics, dental implant, abutment, interarch space, stress, finite element analysis.
