Effects of different surface finishing procedures on the change in surface roughness and color of a polymer infiltrated ceramic network material

Abstract

PURPOSEPolymer infiltrated ceramic network (PICN) materials, also called hybrid ceramics, are new materials in dental market. The manufacturer of the PICN material VITA Enamic suggests 3 different finishing procedures for this new material. In the present study, surface roughness and color differences caused from different finishing procedures of VITA Enamic were investigated.MATERIALS AND METHODS120 specimens were prepared in dimensions 2 × 10 × 12 mm from VITA Enamic hybrid ceramic blocks with 'high translucency' and 'translucency 2M2' shades. The specimens were divided into 8 groups. For each group, different finishing procedures suggested by the manufacturer were performed. Surface roughness values were determined by a tactile portable profilometer. Color changes were evaluated using a clinical spectrophotometer. The data were analyzed using one-way ANOVA and Tukey's post-hoc comparison. The significance level was set at α=0.05.RESULTSThe roughest surfaces were observed in Glaze Groups. Their surface roughness values were similar to that of the control group. Clinical Kit and Technical Kit groups did not show a statistically significant difference regarding surface roughness (P>.05). The largest color difference regarding ΔE00 was observed in Clinical Kit finishing groups. There were also statistically significant color changes between the groups (P<.05). However, all the groups showed clinically acceptable color change (ΔE00<2.25) except Clinical Kit Groups (ΔE00>2.25).CONCLUSIONWithin the limitations of the present study, it may be suggested that finishing the VITA Enamic restorations by Technical Kit instead of Glaze and Clinical Kit gives better clinical performance in regard to surface roughness and shade matching.

In Vitro Effect of Alcohol and Non-Alcohol Based Mouth Rinses on Color Stability of CAD/CAM Resin Ceramic and Feldspathic Ceramics

“…In addition. VITA ENAMIC had better internal and marginal adaptation than feldspathic ceramics as reported by pervious researches (20) . In terms of color matching, the manufacturer stated that VITA ENAMIC offers material properties that are almost identical to those of natural teeth.…”

A literature review on the new polymer‐infiltrated ceramic‐network material (PICN)

“…Surface roughness is directly related to the optical properties of the materials. Özarslan et al showed different values of surface roughness and color changes when different finishing procedures were performed on PICN. The manufacturer of PICN (Vita) suggests 3 different finishing and polishing procedures (Technical Kit, Clinical Kit and VITA Enamic Glaze), which were tested.…”

“…Clinical Kit and Technical Kit groups did not show significant difference regarding surface roughness. Thus, it was suggested that the use of the Technical and Clinical Kits can cause better performance of the PICN material …”

Effect of Different Surface Treatments on Bond Strength of Resin Cement to a CAD/CAM Restorative Material

“…It has been reported that this novel material is expected to have many advantages including decreased brittleness, hardness, and rigidity; enhanced flexibility; and better machinability and fracture toughness than ceramics . It is intended to create a material with the desired mechanical properties of ceramics and composites, which are conventional restorative materials …”

“…3 It is intended to create a material with the desired mechanical properties of ceramics and composites, which are conventional restorative materials. 7 The adhesion of indirect restorations to the tooth structure is a critical step affecting longevity and success of treatment. Bonding between indirect materials and tooth, obtaining high retention, preventing microleakage, and enhancing marginal adaptation are challenging issues.…”
