OBJECTIVES: To evaluate the long-term longevity and @entity1 -reported outcomes of two-unit cantilevered ( @entity48808 ) and three-unit fixed-fixed (FF3) @entity2300 ( @entity2300 ) for the replacement of a maxillary permanent incisor. MATERIALS AND METHODS: Twenty-eight subjects were randomly assigned to receive either a @entity48808 or FF3 RBFPD placed by one operator. Prosthesis longevity was determined by clinical examination and history. Success was defined as absence of complications requiring intervention and survival as retention of the original prosthesis in mouth. Subjects' satisfaction was assessed using visual analogue scale (VAS) and oral health-related quality of life (OHRQoL) using Oral Health Impact Profile (OHIP-49). Outcomes were analysed with t-test/Mann-Whitney U test, chi-square and log-rank test at significance level a=0.05. RESULTS: Twenty-two subjects were reviewed. Thirteen of fifteen @entity48808 and ten of fourteen FF3 @entity2300 were examined (79.3 percent response rate) with a mean service life of 216.5  20.8months. All @entity48808 @entity2300 survived with no complications while only 10 percent of FF3 experienced no complications and only 50 percent of them survived (both P=0.000). @entity48808 had a significantly better success and survival rate than FF3 (P=0.000 and P=0.009, respectively). There was no significant difference in subjects' satisfaction and OHRQoL apart from @entity48808 group subjects had a higher satisfaction in cleaning of the prosthesis (84.1  13.6) than FF3 group (72.6  11.7) (P=0.05). CONCLUSIONS: Two-unit cantilevered @entity2300 were observed to have a significantly better success and survival than the FF3 design for the replacement of a maxillary incisor. Good @entity1 -reported outcomes have been found for @entity2300 in single-tooth replacement in aesthetic zone.
