“…There are only a few studies available that examine the surface properties of PEEK material and how these properties can be enhanced ( 4 , 7 , 13 , 14 ). Surface properties and roughness values of restorative materials play a significant role in adhesion, a stage of plaque formation.…”

“…To ensure that the prosthetic restorative materials exhibit ideal surface properties, it is crucial to select the most effective polishing protocol after performing occlusal adjustments during intraoral trial sessions and production stages of the restorations. The most important factor in choosing a polishing protocol is to achieve a shiny and smooth restoration surface with low Ra values, which prevents bacterial adhesion ( 7 , 13 , 14 , 16 ). In the current study, Ra values ranged from 0.06 μm to 0.77 μm.…”

“…One of these essential parameters is the quality of the material surface polishing. This is because the surface roughness of the dental material is a risk factor in the development of bacterial retention, caries, gingivitis,periodontitis, peri-implantitis, stomatitis, harmful abrasive effects on natural teeth or restoration, and other problems ( 1 , 7 , 8 , 12 , 13 , 14 , 15 , 16 , 17 ). Previous studies have reported that the clinical acceptable threshold for the roughness of a prosthetic restoration surface is 0.2 μm ( 7 , 8 , 18 ).…”

“…There are many polishing materials and laboratory or chairside polishing protocols that can be used in dentistry ( 1 , 7 , 8 ). However, little is known in the literature about a user guide for these protocols, the effect of polishing on PEEK material surface roughness, and which protocols provide a more successful surface finish of the PEEK material ( 4 , 7 , 8 , 12 , 13 , 14 ).…”

Purpose: This study aimed to evaluate the effects of different polishing protocols on the surface properties and color stability of the polyetheretherketone (PEEK). Materials and methods: A total of 96 disc-shaped specimens were fabricated from PEEK material and divided into 6 different groups: control (CN), ‘‘Abraso-Starglanz’’ polishing paste (A), ‘‘Yildiz’’ polishing paste (Y), ‘‘Enhance’’ polishing system (EN), ‘‘Super snap’’ polishing kit (SS), and silicone polisher (SP). Surface roughness (Ra) were measured with a profilometer and the surface topography was examined under scanning electron microscope. Color differences were measured with a spectrophotometer according to the CIEDE2000 (∆E00) formulation before and after coffee immersion. Data were statistically analyzed with Kruskall–Wallis and Spearman's correlation analysis (p<0.05, p<0.001). Results: A statistically significant difference was observed between the Ra measurements of the polishing protocols (p<0.001). Ra measurements except A, Y, and SS groups were found to be higher than the clinical acceptable threshold of surface roughness (0.20 μm). In ΔE00 measurements, statistically significant differences were observed between the CN and SP (p=0.041), EN (p=0.001), and A (p=0.002) polishing protocols. No correlation was found between Ra and color stability. Conclusion: Only in the A, Y and SS polishing protocols, Ra measurements were not found to be risky in terms of acceptable threshold of surface roughness. Polishing protocols have also generally failed to maintain the color stability. Considering the surface roughness and color stability, the ‘‘Abraso-Starglanz’’ paste may be suitable method for PEEK material.

“…This may be attributed to the production method, as disks for the PEEK and PPSU groups were made utilizing compression molding and additive manufacturing. The fracture behavior of polymers is affected by additive production parameters, including layer height, nozzle diameter, and bed temperature (34,35) .…”

Aim:The marginal and internal fit, fracture strength, and mode of failure of 3rd printed CAD/CAM provisional crowns were compared to those of direct provisional crowns. Subjects and Methods; Following tooth preparation guidelines upper right first premolar Farasco tooth. 3rd printed Polyphenylene sulfone (PPSU), milled CAD-CAM Polyetheretherketone (PEEK) and ProtempTM4 manually fabricated were the materials tested (control group). The crowns were divided into three groups (n=20): Groups 1, 2, and 3: Each crown was examined for marginal and internal fit, fracture strength, and failure mode. In a universal test machine, the maximum force at fracture (Fmax) was measured, and the mode of failure was reported at 0.5 mm/min. ANOVA, chi-squared test, and Tukey's tests (p 0.05). Results: the average marginal gap of PEEK(Polyetheretherketone) CAD-CAM was less than the 3 rd printed PPSU (Polyphenylene sulfone) and direct fabrication Protemp™4, PPSU 80.64±8.34 µm, PEEK 60.64±9.54 µm, and Protemp4 120.64±32.34 µm. This indicated a statistically significant difference in the marginal gap distances between all groups (p<0.001). The average internal gap value for each group was: PPSU 155.32±20.56 µm, PEEK 123.45±16.11 µm, and Protemp™4 260.34±34.45 µm. There was a statistically significant difference in fracture strength between all classes. (p<0.001). Each group's average fracture strength was: PPSU 657.43±23.43 N, PEEK 870.45±18.87 N, and Protemp™4 427.34±25.43 N. Conclusion. CAD/CAM PEEK temporary crowns and the 3 rd printed PPSU material exhibited significantly higher fracture strength and less marginal and internal gap measurements than conventionally fabricated Protemp™ 4 resins after the aging regimen.
