Studied groups were patients with Spherblock ball attachment (58 patients), Dolder bar with cantilever (36 patients), and Locator attachment (9 patients). Marginal bone\u2010loss around implants, prosthetic complications, soft tissue status of the implants (gingival index, plaque index, pocket depth, and bleeding on probing) were used to compare studied groups. Visual Analogue Scale (VAS) criteria was used to assay patient's satisfaction. One\u2010way ANOVA, Scheffe, Kruskal\u2013Wallis, Mann\u2013Whitney, and Fisher's exact tests, were used for the data analysis (<jats:italic>\u03b1<\/jats:italic>\u00a0=\u00a00.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>One hundred and three patients (46 male, 57 female, mean age 64.7\u2009\u00b1\u20098.6) with 206 implants (Strauman) were studied. The implant survival rate was 100% with mean bone loss of 0.22\u2009mm around implants in 5\u2009years. Prosthetic complications including attachment wear and denture fracture occurred more often with ball attachments. The number of attachment replacement, and post insertion appointments were significantly less in patients with bar attachments (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05).
