OBJECTIVE: To compare oral health-related quality of life (OHRQoL) 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 OHRQoL. METHODS: A case-control study among 78 subjects who received ISC or cRBB rehabilitation at a teaching hospital (39 ISCs and 39 cRBBs). OHRQoL 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 cRBB (P = 0.53). Among subjects with complicated restorations, those with major complications reported significantly higher OHIP scores (poorer OHRQoL) than those with minor complications (P = 0.02). Subjects who experienced multiple complications had significantly higher OHIP scores (poorer OHRQoL) 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, OHRQoL was similar irrespective of treatment modality (ISC or cRBB). Among those who experienced complications their OHRQoL was associated with the nature of complications, treatment modality and gender.
