Description
Summary:Objectives The purpose of this study was to analyze the influence of the shape of various implants and the density of substrate on primary stability using a combination of methods. Materials and methods Fifty-four Neodent® brand cylindrical and conical implants with different prosthetic platforms were used. Implants were inserted into a pork rib bone and polyurethane blocks. Primary stability was assessed by insertion torque (IT), resonance frequency analysis (RFA), and pullout strength. Screws were also analyzed by scanning electron microscopy (SEM) before insertion and after removal to justify their use for inserting in different substrates. Results The conical cone morse implant had the highest average for all of the assays performed and was significantly different ( p
