The aim of this research was to analyze satisfaction with prosthodontic rehabilitation of intellectually disabled (ID) patients provided by their parents/caregivers. A total of 12 ID patients received fixed dentures (FDs) and 10 patients received removable dentures (RDs). Parents/caregivers answered a questionnaire related to prosthodontic rehabilitation (1 = unsatisfactory, 5 = excellent). Parents/caregivers were mostly satisfied with their childrens' oral rehabilitation (results were skewed toward the highest scores). There was a significant improvement in masticatory function and a reduction of avoiding certain foods after both FD and RD therapy. RD therapy significantly improved ID patients' social lives. However, FD therapy increased problems with oral hygiene maintenance. Prosthodontic rehabilitation improves oral function of ID patients.
