Prosthodontic rehabilitation of a patient diagnosed with multiple idiopathic root resorption.

A female college student was referred by her general dentist for evaluation of the interproximal caries-like lesions discovered during her biannual visit. The lesions were determined to result from external resorption of unknown origin. After the most affected teeth had been extracted and the other teeth were restored after periodontal surgery, an interim partial removable dental prosthesis was placed. Two months later, the resorption pattern had proliferated to the rest of her dentition, thus revising the treatment plan to involve full mouth extractions and to place immediate maxillary and mandibular complete removable dental prostheses. Subsequently, 6 titanium dental implants were placed in each arch, and, after healing, opposing metal ceramic screw-retained fixed dental prostheses were inserted.
