Prosthetic rehabilitation of a metal-allergic patient using polyetheretherketone (PEEK)
Abstract
A female patient with a metal allergy visited our clinic for the purpose of receiving a dental prosthesis. In her case, we
planned a complete maxillary denture made of polymethyl methacrylate (PMMA) for her edentulous upper jaw. For her
subtotal mandibular edentulism, we designed a telescopic overdenture consisting of primary telescopes made of Y-ZrO2
ceramic and secondary telescopic caps and framework milled from a single block of PEEK polymer.
In the case of telescopic anchorage systems, in addition to the traditionally recommended materials such as noble metal
and CoCr alloys, these alternative materials, combined with digital technological solutions, provide adequate retention
during denture use.
