Peek material in dentistry11/24/2023 ![]() As civilization advanced, there has been continuous development in both the quantity and quality of materials in order to obtain a material that is biocompatible, easy to manipulate, and control so as to make a prosthesis that is esthetically pleasing and also functionally effective. Adapting to the available contemporary materials for dental applications was necessary in an attempt to restore the function and appearance. Losing teeth as a result of accidents or diseases has proved to be troublesome to mankind throughout the ages. ![]() The Journal of Contemporary Dental Practice (2021): 10.5005/jp-journals-10024-3077 I NTRODUCTION Keywords: Flexural strength, Heat-activated PMMA, PEEK, Vickers microhardness test. Further researches are needed to be carried out.Ĭlinical significance: PEEK as a denture base exhibits adequate flexural strength prolonging its clinical longevity and overcoming the most common reason for the failure of PMMA denture base that results in fracture. The hardness of PEEK and PMMA was 24 VHN and 19.4 VHN, respectively.Ĭonclusion: It was observed that PEEK can be a potential denture base material with superior properties as compared to PMMA. ![]() Result: The flexural strength of PEEK was 183 MPa, while that of PMMA was 84 MPa. The readings were subjected to an unpaired t -test for comparison of flexural strength and hardness of PEEK and PMMA. The values obtained were subjected to statistical analysis. The group A specimens were tested for flexural strength by universal testing machine (UTM), and group B samples were subjected to hardness test using Vickers microhardness tester. Both the groups were further divided into subgroups consisting of 20 samples of PMMA and PEEK. Material and methods: A total of 80 samples of PEEK and PMMA were prepared and divided into two groups: group A and group B, of 40 each. J Contemp Dent Pract 2021 22(2):179–183.Īim: Evaluation and comparison of flexural strength and hardness of heat-cured polymethylmethacrylate (PMMA) denture base with polyetheretherketone (PEEK).
