“…This could be owed to the high kinetic energy of alumina particles at the tested pressure. Their impact causes the surface to become microporous (Parkar et al, 2021). This is confirmed in the current study by the surface topography that showed that air abrasion group had abraded textures with multiple porosities, deep grooves and cracks and some superficial particles.…”

Aim: To evaluate the efficacy of sulfuric acid treatment of PEEK's surface on the shear bond strength to veneering composite compared to air abrasion.Subjects and methods: 20 disc-shaped samples (10 mm diameter -2 mm thickness) were produced from breCAM BioHPP blank and were randomly and equally divided into 2 groups according to the surface treatment; group H2So4: treatment with 98% sulfuric acid (etching), group Al2O3: treatment with 110 μm aluminum oxide particles (air abrasion).Visio-link primer was applied to samples followed by Crea.lign veneering composite. Scanning electron microscope (SEM) was used for the measurement of surface roughness. Universal testing machine was used to perform the shear bond strength (SBS) test. Elemental analysis was done after surface treatment and after shear bond strength test using energy dispersive X-ray analysis (EDX).Results: Statistical analysis showed that group Al2O3 (30.26 ± 3.97 μm) had significantly higher surface roughness than group H2So4 (22.95 ± 2 μm). While group H2So4 (11.72 ± 2.93 MPa) had significantly higher shear bond strength than group Al2O3 (9.07 ± 1.63 MPa). Elemental analysis showed increase in sulfur and oxygen in group H2So4 and increase in carbon and silica in group Al2O3. Conclusion:98% sulfuric acid surface treatment of PEEK enhances SBS more than aluminium oxide air blasting.

This review focuses on the current disparities and gaps in research on the characteristics of the oral ecosystem of denture wearers, making a unique contribution to the literature on this topic. We aimed to synthesize the literature on the state of current knowledge concerning the biological behavior of the different polymers used in prosthetics. Whichever polymer is used in the composition of the prosthetic base (poly methyl methacrylate acrylic (PMMA), polyamide (PA), or polyether ether ketone (PEEK)), the simple presence of a removable prosthesis in the oral cavity can disturb the balance of the oral microbiota. This phenomenon is aggravated by poor oral hygiene, resulting in an increased microbial load coupled with the reduced salivation that is associated with older patients. In 15–70% of patients, this imbalance leads to the appearance of inflammation under the prosthesis (denture stomatitis, DS). DS is dependent on the equilibrium—as well as on the reciprocal, fragile, and constantly dynamic conditions—between the host and the microbiome in the oral cavity. Several local and general parameters contribute to this balance. Locally, the formation of microbial plaque on dentures (DMP) depends on the phenomena of adhesion, aggregation, and accumulation of microorganisms. To limit DMP, apart from oral and lifestyle hygiene, the prosthesis must be polished and regularly immersed in a disinfectant bath. It can also be covered with an insulating coating. In the long term, relining and maintenance of the prosthesis must also be established to control microbial proliferation. On the other hand, several general conditions specific to the host (aging; heredity; allergies; diseases such as diabetes mellitus or cardiovascular, respiratory, or digestive diseases; and immunodeficiencies) can make the management of DS difficult. Thus, the second part of this review addresses the complexity of the management of DMP depending on the polymer used. The methodology followed in this review comprised the formulation of a search strategy, definition of the inclusion and exclusion criteria, and selection of studies for analysis. The PubMed database was searched independently for pertinent studies. A total of 213 titles were retrieved from the electronic databases, and after applying the exclusion criteria, we selected 84 articles on the possible microbial interactions between the prosthesis and the oral environment, with a particular emphasis on Candida albicans.

“…Parker et al assessed different surface treatments and shear bond characteristics of PEEK to resin cement and glass ionomer cement. They concluded that sulfuric acid-treated samples had the highest shear bond strength [ 16 ]. However, it was evident that the physical alteration of the surface introduces a favourable morphology for adhesion but does not improve the hydrophilicity of the material.…”

Surface Treatments of PEEK for Osseointegration to Bone

Polymers, in general, and Poly (Ether-Ether-Ketone) (PEEK) have emerged as potential alternatives to conventional osseous implant biomaterials. Due to its distinct advantages over metallic implants, PEEK has been gaining increasing attention as a prime candidate for orthopaedic and dental implants. However, PEEK has a highly hydrophobic and bioinert surface that attenuates the differentiation and proliferation of osteoblasts and leads to implant failure. Several improvements have been made to the osseointegration potential of PEEK, which can be classified into three main categories: (1) surface functionalization with bioactive agents by physical or chemical means; (2) incorporation of bioactive materials either as surface coatings or as composites; and (3) construction of three-dimensionally porous structures on its surfaces. The physical treatments, such as plasma treatments of various elements, accelerated neutron beams, or conventional techniques like sandblasting and laser or ultraviolet radiation, change the micro-geometry of the implant surface. The chemical treatments change the surface composition of PEEK and should be titrated at the time of exposure. The implant surface can be incorporated with a bioactive material that should be selected following the desired use, loading condition, and antimicrobial load around the implant. For optimal results, a combination of the methods above is utilized to compensate for the limitations of individual methods. This review summarizes these methods and their combinations for optimizing the surface of PEEK for utilization as an implanted biomaterial.
