Influence of novel implant selective laser melting framework design on mechanical durability of acrylic veneer

Abstract

Background: A novel implant framework design is proposed to improve the mechanical durability of acrylic veneer. Purposes: Comparing the mechanical durability of acrylic veneer on implant frameworks fabricated from selective laser melting (SLM) with novel design against conventional computer numeric controlled (CNC) milled frameworks. Materials and Methods: Implant titanium frameworks with distal cantilever were fabricated by SLM (n = 10) and CNC milling (n = 10). The CNC frameworks had multiple vertical pins, while the SLM frameworks had 3D metal networks of horizontal beams connected by vertical struts. All the frameworks were veneered with acrylic teeth and resin material and were subject..
