dc.description.abstractObjectives: To compare the success of two different tooth replacement strategies for partially dentate older adults; namely resin bonded bridgework (RBB) provided to restore patients according to the principles of the shortened dental arch concept (SDA) and conventional full-arch rehabilitation with removable dental prostheses (RDPs). Methods: A randomised controlled clinical trial (RCT) was conducted with partially dentate adults aged 65 years or older. Each patient from the RDP group had all missing natural teeth replaced with cobalt–chromium framework RDPs. Each patient from the SDA group was restored to 10 occluding pairs of natural and replacement teeth using RBB. Patients were followed-up at 6, 12, 24, 36 months. Success rates were generated according to defined success criteria. Log-rank tests and Cox’s proportional hazard models were used to compare the success of the two treatment strategies. Results: After 36 months, 89 patients completed the RCT; n = 45 in the RDP group and n = 44 in the SDA group. The overall success rate of the SDA treatment was 90.4% compared to 73.0% for RDPs (p = 0.005). In the upper arch SDA treatment was 100% successful compared to 86.4% for RDPs (p = 0.019). In the lower arch, lower success rates were reported for both the SDA treatment (80.0%) and RDPs (60.0%) (p = 0.054). Further analyses with cox’s proportional hazard models demonstrated that SDA treatment was significantly more successful than RDPs (Hazard Ratio: 2.47, p = 0.04). Conclusions: After 36 months SDA treatment using RBB was significantly more successful than RDPs used for conventional full-arch rehabilitation in partially dentate older adults. Clinical significance: Functionally orientated treatment according to the principles of the SDA is a feasible alternative to RDPs for partially dentate older patients. SDA treatment using RBB can achieve higher success rates compared to RDPs in this patient group.en
