OBJECTIVES: To determine correspondence between clinician's and patient's appreciation of existing removable dentures and to assess the main determinants of patient satisfaction with the aim of improving treatment outcomes. METHODS: This cross-sectional study was conducted over a three-year period among 115 patients with mandibular single remaining teeth, who wore lower removable clasp-retained and overdentures. After detailed examination these patients—67 females (58,3%), 48 males (41,7%) of mean age 63.5 years (SD 13.0), were categorized in Class III—substantially compromised dental status (American College of Prosthodontists Classification System,2002), ranks of retention and stabilization of a lower denture on its foundation were determined. Oral Health Self-Assessment was aided by the validated translation of the 5-item structured questionnaire (G.D.Slade,2007). Data were analyzed using Spearman's rho in the SPSS (Statistical Package for Social Sciences) for Windows software (version 12.0).  RESULTS:  Patient dissatisfaction was the most frequently associated with chewing pain (28%) and interrupted meals (27%). These reported causes of denture discomfort were followed by a need of treatment (19%), avoiding speech and laughing (16%) and difficulty relaxing—10% cases. A statistically significant positive correlation was found between the high scores of lower denture instability and chewing pain (rho=0,67), need of treatment (rho=0,48), while stronger-to-weak negative correlation—with interrupted meals (rho=-0,35), avoiding speech and laughing (rho=-0,27) and difficulty relaxing (rho=-0,14). CONCLUSIONS: Denture clinical scores and patient perceived comfort have multilateral correlation. In each clinical case attainable prosthodontic goals are helpful in increasing patient satisfaction and improving treatment outcomes.
