Abstract:Objectives:The aim of this study was to assess the effects of different resin-based and ceramic superstructure materials and two different abutment types on the stress distribution of the abutment screw using the method of three-dimensional finite element stress analysis.
Materials and Methods:A three-dimensional implant, abutment (zirconia and titanium), abutment screw, crown (zirconia reinforced lithium silicate, lithium disilicate, polymer-infiltrated resin ceramic, and PEEK), and alveolar bone were designe… Show more
