Comparative Evaluation of Tensile Bond Strength of Poly Ether Ether Ketone (PEEK) and Zirconia Copings Using Resin Cement with or without Adhesive: An In Vitro Study

Abstract

This in vitro research aimed to evaluate the Tensile Bond Strength of Poly Ether Ether Ketone and Zirconia copings using resin cement with or without Visio.link adhesive. From commercially available Zirconia and PEEK, blocks were machined milled using (CAD)/(CAM) to obtain 20 Zirconia and 20 PEEK copings. These specimens were sandblasted using 110 μm of alumina. The two main groups (20 Zirconia and 20 PEEK copings) were divided further into 4 subgroups, GROUP 1 (n = 10) PEEK substructure with self-adhesive resin cement without pretreatment, and GROUP 2 (n = 10) PEEK substructure with self-adhesive resin cement pre-treated with Visio.link adhesive. GROUP 3 (n = 10) Zirconia copings with self-adhesive resin cement without pretreatment. GROUP 4 (n = 10) Zirconia copings with self-adhesive resin cement pre-treated with Visio.link adhesive. Universal testing machine was used to evaluate the tensile bond strength of these copings. The results were analyzed using SPSS software Version 25.0 (SPSS Inc., Chicago, IL, USA). One-way ANOVA and independent t-test were used to compare the mean scores. Statistically significant increase was observed in Tensile Bond Strength of samples when Visio.link adhesive was used. Tensile Bond Strength of PEEK copings and Zirconia copings with Visio.link adhesive is considerably greater than PEEK copings and Zirconia copings without adhesive. The mean Tensile Bond Strength of Zirconia (with or without adhesive) is less as compared to Tensile Bond Strength of PEEK (with or without adhesive), but the difference is not statistically significant.

Synthetic materials in craniofacial regenerative medicine: A comprehensive overview

“…It is important to note that they have many disadvantages, including the fact that they are highly susceptible to contamination by bacteria (like endotoxins), lack tunability, react immunologically, degrade at an uncontrollable rate, and do not have a mechanical expectations. In terms of biological aspects, these have several disadvantages in terms of their lack of cellular adhesion sites, so they require chemical modification to enhance the cells’ adhesion to them to improve their performance ( Heboyan et al, 2018a ; Heboyan et al, 2018b ; Heboyan et al, 2020a ; Heboyan et al, 2020b ; Heboyan et al, 2021b ; Reddy et al, 2021 ; Heboyan et al, 2022b ; Heboyan et al, 2022c ; Marya et al, 2022c ; Heboyan et al, 2022d ; Heboyan et al, 2022e ; Heboyan et al, 2022f ; Kakkad et al, 2022 ; Karobari et al, 2022 ). The following describes the most synthetic materials used in craniofacial TE.…”

Insights into Polymeric Materials for Prosthodontics and Dental Implantology

“…Nowadays, a large variety of prostheses both in medicine and dentistry are increasingly made of polymers and polymer-based materials [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. The physical characteristics of Poly(methyl methacrylate) (PMMA) such as durability, strength, light weight and high impact toughness prevail over those of glass and polystyrene, while its resistance to the environment is much higher as compared to other plastics indicated for biomedical application [ 1 , 2 , 3 ].…”

“…In addition to its mechanical properties’ improvement, the usage of ZrO 2 nanoparticles decrease the biofilm adherence to denture bases and removable dentures. Depending on the dose, the C. albicans biofilm’s bioactivity can be properly reduced, showing anti-adhesion activity when a high Ag-NP concentration (5%) is used [ 3 , 5 , 6 ].…”

“…Therefore, it can tolerate high temperatures without any substantial degradation. Due to its exceptionally low allergenic potential, it can rarely induce immune responses after intraoral application [ 5 , 7 , 8 , 9 , 10 ]. Therefore, further studies evaluating this property can contribute to the scientific literature and truly demonstrate the potential usage and disadvantages of this property for prosthetic and implant dentistry.…”

“…Meanwhile, long-term antimicrobial medication releases, such as metronidazole, ciprofloxacin, or minocycline, were supported by polymeric coatings [ 7 , 20 ]. Nevertheless, some mechanical properties of polymeric coatings can be low and its use can be compromised due to plastic deformation at high stress levels [ 5 ]. In this sense, more studies in this topic are needed.…”
