Comparison of the Surface Roughness of CAD/CAM Metal-Free Materials Used for Complete-Arch Implant-Supported Prostheses: An In Vitro Study. Biomedicines. 2023 Nov 13;11(11):3036. doi: 10.3390/biomedicines1111303610.3390/biomedicines11113036https://hdl.handle.net/20.500.14352/1123242023 Descuento MDPIThe roughness of the intra-oral surfaces significantly influences the initial adhesion and the retention of microorganisms. The aim of this study was to analyze the surface texture of four different CAD-CAM materials (two high-performance polymers and two fifth-generation zirconia) used for complete-arch implant-supported prostheses (CAISPs), and to investigate the effect of artificial aging on their roughness. A total of 40 milled prostheses were divided into 4 groups (n = 10) according to their framework material, bio.HPP (B), bio.HPP Plus (BP), zirconia Luxor Z Frame (ZF), and Luxor Z True Nature (ZM). The areal surface roughness “Sa” and the maximum height “Sz” of each specimen was measured on the same site after laboratory fabrication (lab as-received specimen) and after thermocycling (5–55 °C, 10,000 cycles) by using a noncontact optical profilometer. Data were analyzed using SPSS version 28.0.1. One-way ANOVA with multiple comparison tests (p = 0.05) and repeated measures ANOVA were used. After thermocycling, all materials maintained “Sa” values at the laboratory as-received specimen level (p = 0.24). “Sz” increased only for the zirconia groups (p = 0.01). B-BP exhibited results equal/slightly better than ZM-ZF. This study provides more realistic surface texture values of new metal-free materials used in real anatomical CAISPs after the manufacturing and aging processes and establishes a detailed and reproducible measurement workflow.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/journal article2227-9059https://doi.org/10.3390/biomedicines1111303638002036https://www.mdpi.com/2227-9059/11/11/3036https://pubmed.ncbi.nlm.nih.gov/38002036/open access616.314-089.843616.314-089.28615.46Surface roughnessSurface textureCAD/CAMHigh-performance polymersPEEKZirconiaThermocyclingComplete-arch implant-supported prosthesesOdontología (Odontología)Prótesis dentalMateriales dentales3213.13 Ortodoncia-Estomatología
