The Use of a Modified Poly‐Ether‐Ether‐Ketone (PEEK) as an Alternative Framework Material for Removable Dental Prostheses. A Clinical Report

Abstract

This clinical report presents a modified poly-ether-ether-ketone (PEEK) as an alternative material for the fabrication of distal extension removable dental prosthesis (RDP) frameworks. This material can be used for patients allergic to metals, or who dislike the metallic taste, the weight, and the unpleasant metal display of the denture framework and retentive clasps. This modified PEEK material, known as BioHPP, is a biocompatible, nonallergic, rigid material, with flexibility comparable to bone, high polishing and low absorption properties, low plaque affinity, and good wear resistance. It has been used for years in orthopedics and medical technology. BioHPP frameworks can be constructed either via CAD/CAM manufacturing or via the conventional lost wax technique. The clinical use of a BioHPP RDP framework is presented as an alternative for the treatment of a distal extension case.

Bonding to Different PEEK Compositions: The Impact of Dental Light Curing Units

“…For this reason, many studies have investigated the material regarding the relevant properties, e.g., wear resistance [6], fracture load [7,8,9], retention load and retention forces [10,11], hardness [12], flexural behavior [13], and discoloration [14]. PEEK has thus been proven to be a suitable material for fixed dental prostheses (FDPs) [15,16,17] and long-term restorations [4,6,10,11,12,13,18]. …”

An In Vitro Evaluation of the Effect of Various Adhesives and Surface Treatments on Bond Strength of Resin Cement to Polyetheretherketone

“…Additional advantages of this polymer are elimination of allergic reactions and metallic taste, high polishing qualities, low plaque affinity, and good wear resistance . An in vivo study reported that PEEK should probably be considered as an alternative removable partial denture framework material for patients with taste sensitivity or allergies to conventional Cr‐Co frameworks . Although PEEK has significant advantages for dental applications, difficulties in establishing a strong and durable adhesion to dental material are the major clinical disadvantage .…”

Polyetheretherketone (PEEK) as a medical and dental material. A literature review

“…Five were clinical reports [2,6,8,18,24] and 35 were papers on PEEK surface treatments [13][14][15][16][17] how the bioactivity of PEEK can be improved [1,21]; the characteristics of CFR-PEEK [3,7,[19][20]; the biocompatibility of PEEK [5]; PEEK applications [4,8,[10][11]30]; PEEK biofilm formation [22,[31][32][33][34], PEEK as an abutment material and as an implant material [12,23,[25][26][27][28][29]35,40] and the use of CAD-CAM with PEEK [36][37][38][39]. …”

“…It is also wear-resistant, compatible with many reinforcing agents (such as glass and carbon fibers), stable at temperatures exceeding 300°C. This polymer is very biocompatible in vivo and in vitro, does not cause toxic or mutagenic effects; therefore it is indicative in patients allergic to titanium [1,[4][5][6]. Notwithstanding, Maldonado-Naranjo et al described a case report with clinical evidence of allergy to PEEK.…”

“…Zoidis et al described a case in which modified PEEK containing 20% ceramic fillers (BioHPP) was used, in combination with acrylic resin, the traditional denture base, as an alternative framework material for removable dental prostheses [6].…”
