Cumulative survival rate (CSR<\/jats:styled-content>) of ZI<\/jats:styled-content>, RI<\/jats:styled-content>, prostheses, and complications were recorded during, at least, 10 years of loading. Implant mobility was tested using P<\/jats:styled-content>eriotest\u00ae.

Forty\u2010one were ZI<\/jats:styled-content>. Three RI<\/jats:styled-content> failed (10 years CSR<\/jats:styled-content>\u2009=\u200997.71%). Two ZI<\/jats:styled-content> were partly removed due to perimplant infection (10 years CSR<\/jats:styled-content>\u2009=\u200995.12%). All patients maintained functional prostheses. One patient fractured framework twice. Loosening or fracturing screws happened in 11 patients. Seven patients fractured occlusal material. Four ZI<\/jats:styled-content> abutments in two patients were disconnected because of uncomfortable prostheses. Alveolar height at the ZI<\/jats:styled-content> head level on the right and left sides was 2.64\u2009mm and 2.25\u2009mm, respectively. Mean distance of ZI<\/jats:styled-content> head center to ridge center, on the right and left sides was 4.54\u2009mm and 5.67\u2009mm, respectively. Mean P<\/jats:styled-content>eriotest values (PTv<\/jats:styled-content>) of ZI<\/jats:styled-content> were \u22124.375 PT<\/jats:styled-content>v and \u22124.941 PT<\/jats:styled-content>v before prostheses placement and after 10 years, respectively. Six patients experienced sinusitis 14\u2013127 months postoperatively. 54.55% of the L<\/jats:styled-content>\u2013M<\/jats:styled-content> scores did not present opacification (L<\/jats:styled-content>\u2013M<\/jats:styled-content>\u2009=\u20090) in any sinus.
