Photoelastic stress analysis of load transfer to implants and natural teeth comparing rigid and semirigid connectors. 2006;37(5):345-352. References 6. This article in the form of a clinical case report describes the management of pier abutment case over a period of 5 years with a fixed movable prosthesis. With extended use, particularly in the absence of adequate oral self-care, the RPD may cause traumatic ulcers, stomatitis, or epuli formation and may accelerate bone atrophy in the edentulous areas. RPD abutments demonstrated a significant improve- ment with intracoronal reinforcement (p < .Ol). Results: Five hundred and forty-seven crowns were evaluated (mean follow-up time 1.3±0.9years) in 327 patients.
