Objective To compare oral health‐related quality of life ( OHRQ o L ) among subjects who received implant‐supported crowns ( ISC ) and 2‐unit cantilevered resin‐bonded bridges ( cRBB ) in a bounded single tooth space ( BSTS ) after at least 5 years and to investigate factors associated with their OHRQ o L . Methods A case–control study among 78 subjects who received ISC or c RBB rehabilitation at a teaching hospital (39 ISC s and 39 c RBB s). OHRQ o L was measured using the Oral Health Impact Profile ( OHIP ‐49) and compared between treatment modality. Variations in OHIP scores with respect to “minor complications” (repair of the original “survived” restorations) and “major complications” (replacement of “failed” restorations); and number of complications were determined in bivariate and multivariate analyses (negative binominal regression) controlling for socio‐demographic and clinical factors. Results Oral Health Impact Profile scores were similar among those who received ISC and c RBB ( P = 0.53). Among subjects with complicated restorations, those with major complications reported significantly higher OHIP scores (poorer OHRQ o L ) than those with minor complications ( P = 0.02). Subjects who experienced multiple complications had significantly higher OHIP scores (poorer OHRQ o L ) than those with a single complication ( P = 0.04). In regression analyses (which considered OHIP scores of those with complications), the nature of complications ( P < 0.01), treatment modality ( P = 0.04), and gender ( P = 0.02) emerged as significant factors. Conclusion In the rehabilitation of a BSTS patients, OHRQ o L was similar irrespective of treatment modality ( ISC or c RBB ). Among those who experienced complications their OHRQ o L was associated with the nature of complications, treatment modality and gender.
