Clasp retainers made of metal alloys may be esthetically unappealing or cause allergic reactions.To investigate alternative materials, we used the nonfiller polyetheretherketone (PEEK) to fabricate the clasp retainer of a removable partial denture for the mandibular bilateral distal free-end Camera Cleaning Kit abutment of an 84-year-old female.Two years later, few color and texture changes of PEEK were found macroscopically.
The rest part and the clasp arm fitted well without any deformation.There were no particular occlusal COMPASS or periodontal problems.Subjective satisfaction was expressed by both the practitioner and the patient.
