“…The standard deviation of the Ra was large in the RS group and small in the MS group, indicating that the Ra values in the latter group were approximately correct. Shintani (14) reported that plaque adhesion increases on rougher surfaces. In contrast, Bollen et al reported that Ra values less than 0.2 µm do not affect bacterial adhesion (28), and a study by Nascimento et al showed that bacterial adhesion to titanium and zirconium was insensitive to Ra (29).…”

Relevance of surface characteristics in the adhesiveness of polymicrobial biofilms to crown restoration materials

et al. 2018

We used a polymicrobial (PM) biofilm model to examine associations of bacterial adhesiveness with surface characteristics of various dental materials. Four types of dental materials (apatite pellet, zirconia, ceramic, and composite resin) with rough and mirror surfaces were used. Surface roughness, surface free energy, zeta potential, and colony-forming units (CFUs) of the biofilm formations were measured. Biofilms were cultured for 24 h under anaerobic conditions, plated onto blood agar medium, and anaerobically cultured for 4 days. After culturing, CFU per mm 2 was calculated, and samples were observed under a scanning electron microscope. Means and standard deviations of the experimental data were estimated, and one-way ANOVA and Tukey multiple comparison assays were performed. Pearson correlation coefficients were obtained for the CFU and surface characteristics. Surface roughness and surface free energy appeared to affect generation of PM biofilms on oral materials, and zeta potential was involved in generation of PM biofilms on mirrorground oral materials.

“…The quantity of plaque generated on the surfaces of these materials has varied substantially in clinical trials. However, the surface characteristics of dental materials, as well as the adhesion and generation of biofilms on these surfaces, are rarely reported (14,15).…”

“…Therefore, zirconium is particularly preferred in the front teeth. Zirconia has been proven highly bio-compatible in many studies [3], and the accumulation of bacteria has been reported less than titanium [4]. In this sense, the implant material should provide the needs of the patient mechanical resistance, aesthetic appearance and should have biocompatibility and Osseointegration of dental implant.…”

Purpose: The purpose of this study was to analyze stress distribution patterns in implant restorations created in different length and diameter made of titanium and zirconia by using three dimensional finite element analysis (FEM) with straight and 15˚ angled abutment. Materials and Methods: For titanium models; Ti-6Al-4V for implant fixture, connection element and abutments (straight and 15˚ angled abutment), yttrium tetragonal zirconium polycrystal (Y-TZP) for zirconium framework, Felds phatic porcelain for superstructure material and for zirconia models; Y-TZP for implant fixture, connection element, abutments (straight and 15˚ angled abutment) and zirconium framework, Felds phatic porcelain for superstructure material were used. The implants and their superstructures were modeled using CAD software Creo Elements-Pro5.0 and the mandibula was modeled using MIMICS 13.1 software. Optimum finite element modelled was obtained nium implants with maximum stress for implants of the same length but different diameters, same diameters with different lengths and straight and 15˚ angled abutment showed nearly similar variances. Conclusion: With in the limitations of this study, increasing implant diameter is better than decreasing implant diameter both for titanium and zirconium models but raising implant length is worse than decreasing implant length with applied masticatory forces.

“…[4][5][6] The good mechanical properties and biological compatibility of zirconia (zirconium dioxide) have led to its increased use for various dental applications. 7,8 A number of advantages of ceramics over metal abutments have been reported in the literature: less mucosal discoloration, 9 less adhesion of bacteria, 10 very low or no cytotoxicity as measured in vitro human gingival fibroblast, 11 and mucosal attachment to zirconia that is as good as that to titanium, according to an animal study. 12 The three-year results from a randomized controlled clinical trial comparing customized zirconia and titanium abutments showed no difference in outcome from technical, biological, or esthetic points of view.…”

PURPOSE To determine the effect of the cement type and abutment material on the tensile strength required to dislodge zirconia copings. MATERIALS AND METHODS Two experimental groups of abutments were prepared: (1) titanium abutments (n = 30) and (2) zirconia abutments (n = 30). Sixty zirconia copings (custom designed) were fabricated using 3-dimensional computer-assisted design to have a 6-mm projection above the abutment to accommodate a hole, through which a wire was inserted to attach the zirconia coping to a universal testing machine. Each abutment was placed onto an implant analog embedded in acrylic resin blocks to fit onto the universal testing machine. The zirconia copings were cemented onto the abutments with a provisional luting agent, zinc phosphate (ZP) cement, and adhesive resin cement, and after 5500 thermocycles, a tensile force was applied at a crosshead speed of 0.5 mm/min. The removal force was recorded for each specimen. Two-way analysis of variance (ANOVA) and 1-way ANOVA were used for the statistical analysis (P < 0.05). RESULTS The mean forces necessary to remove the zirconia copings from titanium abutments were 6.52, 83.09, and 251.18 N for temporary cement, ZP cement, and resin cement, respectively. For zirconia abutments, the required forces were 17.82, 116.41, and 248.72 N. CONCLUSIONS The abutment material had no effect on retention, but the cement type affected the retention of the zirconia copings.
