Retention of acrylic denture resins to metal based dentures and removable partial dentures has been accomplished using beads, nail heads, open ladders, or some other macroscopic retentive design. Such retentive configurations may often encroach upon limited interarch space. Additionally, the adequacy of retentive strength found with these methods has been questioned. An alternative to the macroscopic retentive designs had been reported in a technique for relining metal based dentures. This technique suggests the electrochemical etching of base metals, normally associated with metal-etched resin-bonded restorations, as a retentive system for denture acrylic resins. This form of microscopic retention may provide an improvement over the disadvantages of interarch space and retentive bond strength reported with macroscopic designs. The retentive strength of composite resin materials to electrolytically etched based metals has been reported. While these bond strengths have been high, the retentive strength of denture acrylic resin to electrochemically etched based metals has not been investigated. The purpose of this thesis was to examine the retentive bond strength of a denture acrylic resin to an electrochemically etched base metal in comparison to conventional retentive heads.
