Objective: This study aimed to investigate stress distribution in a photoelastic model generated by Ricketts Utility Arch (RUA), also known as Ricketts base arch, for intrusion of mandibular incisors. Stresses in the root thirds of each incisor were compared and the existence of differences in the concentration of stresses between the incisors was also examined. Methods: Fifteen intrusion RUAs ...

Fixed implant-supported prosthesis for the edentulous maxilla has gained tremendous popularity over the years. Multiple prosthetic designs have been introduced in order to accommodate a gamut of clinical situations. Irrespective of the design, it is paramount that the esthetics imparted by the prosthesis be uncompromised. Though esthetics is subjective, a common ground exists where all its fund...
