The purpose of this case report was to present a clinical case of overdenture in a 3-year-old patient with early loss of his primary maxillary teeth, which were extracted due to the presence of early childhood caries. The treatment of choice was an overdenture using the Dalla Bona retention system, and the upper right canine was used as the retainer. The overdenture was placed to help maintain a normal daily diet that was satisfactory for the child and to re-establish masticatory function, speech, and facial aesthetics in the patient.
