“…These findings were in accordance with Stawarczyk et al (17) who studied the spectrophotometric evaluation of PEEK as a core material and showed that CieLab-System and VITA EasyShade parameters showed a significant impact of core, veneering material, and thickness of the veneering material. Also, the results were coinciding with Zeighami et al (18) who revealed that the veneering thickness affected the color and translucency of PEEK restorations.…”

INTRODUCTION: Polyetheretherketone (PEEK) can be used as a core material for fixed prosthodontics. However, information about the optimum veneer thickness of veneered PEEK restorations is still scarce. OBJECTIVES: To evaluate the effect of different composite veneer thickness on the optical properties of PEEK restorations. MATERIALS AND METHODS: Twenty four (n=24) PEEK (BioHPP granules) core disc-shape specimens of 15 mm diameter and 0.8 mm thickness were fabricated and veneered with composite resin (crea-lign, shade A3). The specimens were divided into three groups according to the veneering thickness: core/veneer thickness (mm) of 0.8/1.0, 0.8/1.5, and 0.8/2.0 for groups I, II, and III, respectively. The clinical spectrophotometer (VITA Easyshade) was used for color comparison with the reference color data of the selected shade stored in the device. Statistical analysis was performed with one-way analysis of variance (ANOVA) and student (Unpaired-sample) "t" test. RESULTS: The veneering thickness significantly influenced the ΔE values (p < 0.001). The mean color difference (ΔE) values for groups I, II and III were found to be 8.22(±0.41), 5.13(±0.43) and 3.23(±0.34), respectively. CONCLUSIONS: Color of PEEK restorations was significantly affected by the veneer thickness. The veneer thickness of 2.0 mm showed the best color match with perfect masking ability of the underling PEEK core(ΔE<3.3). In contrast, the veneer thickness of 1.0 and 1.5 mm showed a poor color match with poor masking ability of the underling PEEK core (ΔE>3.3).

“…An in vitro study evaluated the colorimetric properties of different veneering materials on PEEK, zirconium oxide (ZrO 2) , cobalt-chromium-molybdenum alloy (CoCrMo), and titanium oxide. PEEK showed comparable results when compared to well established core materials such as ZrO 2 and CoCrMo with respect to the CieLab-System parameters of the assemblies and the modification of the CieLab-System parameters for each veneering material [72].…”

The use of PEEK in digital prosthodontics: A narrative review

et al. 2020

View full text Add to dashboard Cite

Background: Advanced computer-aided design and computer-aided manufacturing (CAD-CAM) technology led to the introduction of an increasing number of machinable materials suitable for dental prostheses. One of these materials is polyetheretherketone (PEEK), a high performance polymer recently used in dentistry with favorable physical, mechanical and chemical properties. The purpose of this study was to review the current published literature on the use of PEEK for the fabrication of dental prostheses with CAD-CAM techniques. Methods: Electronic database searches were performed using the terms "PEEK", "CAD-CAM", "dental", "dentistry" to identify studies related to the use of PEEK for the fabrication of CAD-CAM prostheses. The search period spanned from January 1990 through February 2020. Both in vivo and in vitro studies in English were eligible. Review articles and the references of the included publications were searched to identify relevant articles. Results: A great number of in vitro studies are available in the current literature pointing out the noticeable properties of PEEK. The use of PEEK has been recommended for a wide range of CAD-CAM fabricated fixed and removable dental prostheses. PEEK was additionally recommended for occlusal splints, intra-radicular posts, implant abutments, customized healing abutments and provisional restorations. However, only a few clinical studies were identified. Conclusions: PEEK could be considered as a viable alternative for CAD-CAM fixed and removable dental prostheses to well-established dental materials. Due to the scarcity of clinical data, clinical trials are needed to assess the longterm performance of PEEK prostheses.

“…PEEK is increasingly used in the manufacture of removable and fixed prostheses [ 96 ], such as dental crowns, bridges and denture clamps in removable dental prostheses [ 38 , 97 , 98 , 99 , 100 ]. This is due to its advantages, including low potential to deduce an allergy, low water solubility, superior biocompatibility, high thermal and chemical resistance, moderate biofilm formation and excellent mechanical properties [ 97 , 98 ].…”

“…Crown restorations made from PEEK exhibit poor aesthetics when restoring anterior teeth. The greyish and opaque color has limited PEEK for crown restorations [ 29 , 31 , 96 , 111 ]. The PEEK framework combined with veneering could provide a satisfactory aesthetic outcome [ 12 ].…”

Review on Development and Dental Applications of Polyetheretherketone-Based Biomaterials and Restorations

et al. 2021

Polyetheretherketone (PEEK) is an important high-performance thermoplastic. Its excellent strength, stiffness, toughness, fatigue resistance, biocompatibility, chemical stability and radiolucency have made PEEK attractive in dental and orthopedic applications. However, PEEK has an inherently hydrophobic and chemically inert surface, which has restricted its widespread use in clinical applications, especially in bonding with dental resin composites. Cutting edge research on novel methods to improve PEEK applications in dentistry, including oral implant, prosthodontics and orthodontics, is reviewed in this article. In addition, this article also discusses innovative surface modifications of PEEK, which are a focus area of active investigations. Furthermore, this article also discusses the necessary future studies and clinical trials for the use of PEEK in the human oral environment to investigate its feasibility and long-term performance.
