| Intervention | Single tooth-supported C-FDP with a single retainer of any design (conventional or resin-bonded) and material | Posterior tooth-supported single-retainer C-FDPs, mostly resin-bonded (metal, PFM, zirconia, glass-ceramic, alumina, fiber-reinforced composite) (n=10) |
| Comparison | Premolar vs molar, maxillary vs mandibular, and mesial vs distal tooth-supported C-FDPs | Premolar vs molar (n=6; RR from 5); maxillary vs mandibular (n=5; RR from 3); mesial vs distal (n=2; no failures, not estimable) |
| Outcomes | Primary: survival rate of prostheses; secondary: incidence of biological and mechanical complications | Failure rate and estimated survival (n=8 in meta-analysis); biological complications (n=5, narrative); mechanical complications (n=5, narrative) |
| Study designs | Randomized, nonrandomized, observational and cohort clinical studies; English language | 5 retrospective, 4 prospective (1 randomized), 1 observational cohort (n=10) |
| Timing | Minimum observation period of 3 years; estimated 3- and 5-year survival | Follow-up 36.0 to 115.2 months; estimated 3- and 5-year survival |
