Background: Different attachment systems for mandibular two-implant overdentures could influence levels of patient satisfaction. Positive consensus of the majority of patients being satisfied does not preclude the possibility of dissatisfaction for some. Purpose: To evaluate patient satisfaction before and after 5 years of wearing mandibular two-implant overdentures using different attachment systems. Materials andMethods: A total of 106 edentulous participants enrolled in a clinical trial completed a preliminary self-report inventory of their original complete denture complaints. New complete maxillary dentures and mandibular two-implant overdentures were provided to each participant using one of six different attachment systems. Patient satisfaction was determined at pretreatment; at baseline with mandibular two-implant overdenture insertion; and then annually for 5 years, using visual analogue and Likert-type scales. Results: Patient satisfaction with mandibular two-implant overdentures at baseline was significantly improved in all domains compared to pretreatment (old dentures) and sustained up to the 5-year recall. The level of satisfaction with Straumann gold alloy matrices at 5 years was significantly lower than that with other attachment systems. Highly significan
