Aim: To determine periodontal status of fixes single prostheses (FSP) made during the year 2013 in Austral University of Chile, and its contralateral homologue (CH).Methods: All patients with FSP made during 2013, that met the selection criteria and agreed to participate were evaluated. During the year 2014 was measured: probing depth, attachment level; bleeding on probing and dental plaque index for each FSP and CH; and consigned biological width invasion. Were measured one FSP and one CH per patient, and 6 sites for each tooth.Results: Seventy-four patients were evaluated. The majority were women (73%), and 63.5% were posterior teeth. The majority had history of previous periodontal disease (85, 1%), of which 58.7% were Periodontitis. Six of the patients with a history of Gingivitis progressed to periodontitis (23.07%); while 100% of patients with no history of periodontal disease maintained their condition. Only 4 of the FSP evaluated had Biological Invasion width. Discussion: Similar results were found for FSP teeth and CH were found about probing depth, clinical attachment level and bleeding on probing. However, was observed a difference in relation to dental plaque index, which was positive in 58.1% CH and 29.7% of teeth with FSP. Under the conditions of this study, it is concluded that the periodontal status of teeth with FSP does not differ from the CH.
