Summary To compare function, patient satisfaction and quality of life of patients with a posterior reduced mandibular arch with those who had all missing teeth replaced with removable partial dentures. Patients with at least three and not more than six posterior occluding pairs of teeth were enrolled sequentially and randomised into one of two treatment groups: a denture and no‐denture group. A research assistant allocated interventions; concealment was ensured using opaque‐sealed envelopes. Analysis of data was performed in stages, adding samples of 10 incrementally, and stopping when the relevant statistical tests indicated a clear conclusion as judged by the power set at 80% or above. Study outcomes included patient satisfaction, function and survival of remaining teeth at 3 and 12 months post‐intervention, using a visual analogue scale and the Oral Impacts on Daily Performance). Statistical analysis was performed by the ‘intention‐to‐treat’ principle. Age range of included patients was 23–55 years (mean = 42·3; s.d. = 9·2), with 78% being females. Most patients (70%) belonged to the low‐ or no‐income group. Nine patients left the study, for different reasons. Primary outcomes for the denture group: 10% of the patients were not satisfied and 20% were unhappy with their function; for the no‐denture group: 85% of the patients (with 15% having left the study) were satisfied with both their function and their non‐denture status. Patients with posterior reduced mandibular dental arches reported greater perceived satisfaction, function and quality of life compared to those who had received a cobalt‐chrome clasp‐retained partial removable prosthesis.
