“…31 On the other hand, it was reported that new tactile probes outperformed 3D scanners in terms of accuracy, which could be advantageous during the dental materials evaluation of wear. 40 Vertical height loss and 2D outcomes for tooth/dental material wear assessment were more clinically relevant since tooth size had no effect. 1,44 However, volumetric measurements were more clinically related and provided more information.…”

“…39 Virtual object reconstruction using 3D scanners permits analyzing its dimensions and surface. 40,41 Accuracy is fundamental for any scanner, which involves exactness-deviation of the scanned object from its actual geometry and precision-deviation between repetitive scans. 4,42,43 In this investigation, a highaccuracy 3D scanner (<7 μm) was used to limit the impact of the scanner's inaccuracy on results.…”

Purpose: Due to a lack of data on their wear behavior, the study aimed to analyze the twobody wear rate of two different composite veneered computer-aided design/computer-aided manufacturing (CAD/CAM) polyetheretherketone (PEEK) posterior crowns after wear simulation using 3D surface deviation. Materials and Methods:Twenty duplicated epoxy resin models of prepared mandibular first molar to receive an all-ceramic crown were fabricated. Twenty CAD/CAM PEEK substructures were manufactured and divided according to the veneering technique into two groups (n=10); group (H): CAD/CAM High Impact Polymer Composite (HIPC) veneered PEEK substructures, and group (C): Conventional Crea.lign composite veneered PEEK substructures (control). The specimens underwent thermal and mechanical loading (49N, 5/55˚C; 120,000 chewing cycles) as antagonized by steatite ceramic balls. 3D surface deviation analysis using a 3D dental scanner and Geomagic Design X software was applied before and after chewing simulation to determine the volumetric wear loss (mm 3 ). Data were statistically analyzed with the Mann-Whitney U test to compare the two groups. The significance level was set at p≤0.05.

“…There are very few studies in the literature on the wear behavior of reinforced PEEK material used in the dental field. [35][36][37] Moreover, although there are some studies on existing CAD/CAM composites and ceramics, [38][39][40][41] no data has been presented on whether this polymer can be an alternative in terms of wear resistance. Therefore, in present study, it was objected to compare the wear behavior of various composite-based materials, polymers and glass ceramics after two-body wear test.…”

Objective To analyze the wear rate of computer‐aided design and computer‐aided manufacturing (CAD/CAM) composites, polyetheretherketones and glass ceramics. Material and Methods Our study groups were prepared from two different resin‐based composites (Brillant Crios, Cerasmart), a glass ceramic (IPS Emax CAD) and reinforced polyetheretherketone (BioHPP) material (n = 10). Premolar teeth were used as antagonists. The specimens, which were subjected to two body wear tests (240,000 cycles, 1.2 Hz, 50N) in the chewing simulator, were scanned with a 3D laser scanner both before and after the wear test. Volume loss and wear depth were determined by means of the obtained images software program. The wear pattern was examined by scanning electron microscopy. Kruskal Wallis test served for analyzing. Results The least volume loss and wear depth were seen in the polyetheretherketone material (0.06 ± 0.04 mm3, 0.02 ± 0.01 mm), while the maximum volume loss was seen in the groups containing resin‐based composite. (p = 0.05). The volume loss value in glass ceramics is between CAD/CAM composites and polyetheretherketone. Conclusion The behavior of polyetheretherketone against enamel was different from glass ceramics and composite materials in terms of the amount of wear. Clinical Significance Polyetheretheketone can be considered as an alternative to other chairside materials in terms of wear resistance.

Purpose To verify whether 3D surface deviation analysis software can detect the surface changes of composite veneered polyetheretherketone posterior crowns following wear simulation compared to optical digital profilometry. Materials and methods Twenty dental crowns, fabricated from CAD‐CAM polyetheretherketone (PEEK) and veneered with high impact polymer composite (HIPC), were subjected to wear test (50N, 5/55°C; 120,000 chewing cycles). Optical digital profilometry and 3D surface deviation using Geomagic design X software was used before and after the wear test to measure volumetric wear loss (mm3). The data were statistically analyzed with Wilcoxon signed‐rank test to compare the two methodologies. The significance level was set at p ≤ 0.05. Results There was no statistically significant difference between the two assessment methods (p‐value = 0.075, Effect size = 0.854). Regarding the optical digital profilometry analysis, HIPC veneered PEEK crowns showed 0.01686 (0.018‐0.02155) mm3 as a median volumetric wear loss value. While the crowns analyzed by 3D surface deviation showed –0.0398 (–0.0913 to –0.0042) mm3 as a median volumetric loss value (p‐value = 0.075, Effect size = 0.854). In addition, there was no statistically significant correlation between wear measurements by optical digital profilometry and 3D surface deviation analyses (ρ = –0.177, p‐value = 0.685). Conclusions There was no significant difference or correlation between optical digital profilometry and 3D surface deviation analyses for volumetric wear loss of veneered PEEK crowns.
