Abstract

From the clinical point of view, primary implant stability is a fundamental requirement. The aim of the present work was to investigate the primary stability of two types of dental implants, with truncated cone (TC) and cylindrical (CL) geometry, by evaluating their performance by means of pull-out tests. Moreover, several samples were tested by varying surgical preparation method as well as the material where the implant was housed in order to assess whether primary stability could be affected by these factors. A critical load which corresponds to a displacement of 0.2. mm in pull-out test was chosen as indicator of the implant primary stability. CL implants had the advantage of requiring lower torques during the installation phase, and thus, applying less local stresses on the bone. Among the housing preparation methods investigated in the present study, the housings realized by using two mill cutters of different diameters for different depths implied higher primary stability for TC implant. © 2014 Elsevier Ltd.
