Within the limitations of an in vitro study, our results indicate that surface roughness as well as wettability may influence the adhesion properties of bacteria on implant surfaces.

Besides surface roughness and morphology, the hydrophobicity and surface free energy (SFE) of an implant surface are known to influence bacterial adhesion [42, 43]. Physico-chemical interactions (non-specific) are composed of van der Waals forces, electrostatic interactions, and acid-based interactions, which in turn define the surface free energy of a substratum [44]. The surface free energy can ...

In the present study, sandblasting (with 50 or 250 μm aluminum trioxide) resulted in significant increases of R a on titanium and ceramic surfaces.

According to the classification by Albrektsson and Wennerberg, smooth ceramic and titanium materials and t...

Besides, the surface material itself and its chemical composition, surface roughness, and hydrophobicity have a crucial influence on the accumulation of microorganisms. In most previous studies on bacterial adhesion on titanium and ceramic surfaces, the quantity of bacterial adhesion showed a direct positive correlation with surface roughness [4, 10, 18, 24,25,26]. In case of interacting surface r...

The problems involved in osseous healing of dental implants appear to be largely solved. Biofilm formation on exposed implant and abutment surfaces, however, is a fortiori crucial for the long-term therapeutic success of an implant, because biofilms are the most frequent cause of peri-implantitis and implant loss [3,4,5,6,7]. Consequently, new implant surface modifications with reduced properties ...

In general, significantly more S. sanguinis adhered to ceramic surfaces than to titanium surfaces (p  0.05 for all comparisons). On ceramic surfaces (smooth ceramic 4668 ± 1562 rfu; medium ceramic 5590 ± 1493 rfu, rough ceramic 6875 ± 428 rfu), higher surface roughness led to increased S. sanguinis adhesion (p  0.05 for all comparisons).

Three-dimensional images of rough and smooth implant surfaces were obtained by means of atomic force microscopy (AFM) using the tapping mode scan of an AFM VEECO machine (Plainview, USA); this method was also used to determine the surface topography.

The aim of the present in vitro study was to investigate bacterial adhesion (by means of the test species Streptococcus sanguinis and Staphylococcus epidermidis) on ten different titanium and zirconia implant surfaces. Surface texture and wettability were modified in well-defined patterns to correlate these surface properties with the amount of initially adhering bacteria and to define the predomi...

Background : The influence of surface texture and ...

Dental implants are one of the most frequently used treatment options for the replacement of missing teeth. The oral microflora and its dynamic interactions with the implant substrata seem to crucially influence the long-term success or failure of dental implants [1,2,3,4,5,6]. As soon as implant surfaces are exposed to the human oral cavity, they are immediately colonized by microorganisms [7, 8]...

The electro-chemical method can be employed for HA-Zn coating deposition on titanium metal, where Ca source was a recycled cuttlebone fish to precipitate HA phases. Using a Zn anode on a low-sustained voltage was able to induce an even coat thickness of HA-Zn precipitation and increase the surface roughness significantly.

Yang et al. prepared a Zn-HA coating on Ti plates by an electrochemical process, and the SEM examination showed irregularly shaped rod-like crystals with hexagonal cross-section; this corresponded well with the current study results. They also concluded that a Zn-HA coating improves proliferation and differentiation of osteoblasts and would enhance implant osseointegration [11]. Ceramic coatings ...

Titanium metal is one of the most widely used biomedical orthopedic materials because of its decent mechanical properties [1]. However, as an inert material, it cannot induce osteogenesis and has no antibacterial properties [2]. In order to improve surface bioactivity of titanium substrates, numerous methods have been proposed to cover it with bio-ceramic coatings [1]. Various clinical studies ...

On ceramic surfaces (smooth ceramic 4668 ± 1562 rfu; medium ceramic 5590 ± 1493 rfu, rough ceramic 6875 ± 428 rfu), higher surface roughness led to increased S. sanguinis adhesion (p  0.05 for all comparisons). A comparison of rough and smooth s...

The aim of the present in vitro study was to investigate bacterial adhesion (by means of the test species Streptococcus sanguinis and Staphylococcus epidermidis) on ten different titanium and zirconia implant surfaces. Surface texture and wettability were modified in well-defined patterns to correlate these surface properties with the amount of initially adhering bacteria and to define the predomi...

Background : The influence of surface texture and ...

Dental implants are one of the most frequently used treatment options for the replacement of missing teeth. The oral microflora and its dynamic interactions with the implant substrata seem to crucially influence the long-term success or failure of dental implants [1,2,3,4,5,6]. As soon as implant surfaces are exposed to the human oral cavity, they are immediately colonized by microorganisms [7, 8]...

This study aims to investigate bacterial adhesion on different titanium and ceramic implant surfaces, to correlate these findings with surface roughness and surface hydrophobicity, and to define the predominant factor for bacterial adhesion for each material. Zirconia and titanium specimens with different surface textures and wettability (5.0 mm in diameter, 1.0 mm in height) were prepared. Sur...

The electro-chemical method can be employed for HA-Zn coating deposition on titanium metal, where Ca source was a recycled cuttlebone fish to precipitate HA phases. Using a Zn anode on a low-sustained voltage was able to induce an even coat thickness of HA-Zn precipitation and increase the surface roughness significantly.

Yang et al. prepared a Zn-HA coating on Ti plates by an electrochemical process, and the SEM examination showed irregularly shaped rod-like crystals with hexagonal cross-section; this corresponded well with the current study results. They also concluded that a Zn-HA coating improves proliferation and differentiation of osteoblasts and would enhance implant osseointegration [11]. Ceramic coatings ...

New ceramic implants are showing a variety of surface characteristics due to different manufacturing processes as shown by other groups [2, 28]. The surface structures of the investigated implants are close to titanium implants.

This could be caused by the lower dosage of yttrium endowment in the stabilization processing in comparison to other impla...

The surface shape (droplet-like surface), which was observed in the SEM samples, can be caused due to the sintering process in which ceramic powder was melted and then formed.

A longer exposure t...

No significant differences were observed between the specific hydrophilic (SAE-HD) and hydrophobic (SAE) surfaces evaluated in this study, in terms of biomechanical properties during the early osseointegration period.

Discussion : Interfacial biomechanical properties ...

In fact, the observed lack of differences between the groups could be attributed to the relatively low number of specimens per group. According to the observed data herein, applying a high power (80%) with the present sample size would had revealed a relatively large difference in removal torque equivalent to 43% between the experimental groups. Regarding removal energy and connection stiffness, t...

Discussion : Interfacial biomechanical properties ...

On the other hand, lack of significant differences between the two groups in the present experiment could be due to the fact that the effect of hydrophilicity, in terms of accelerating bone healing and osseointegration, was unfolded before the first evaluation time-point of 2 weeks, i.e., during the very early healing period. Consistently, pre-clinical investigations show the potential of chemica...

Improving surface wettability aims to increase the implant surface area achieving most favorable protein adsorption and cellular adhesion and thereby to positively regulate the biological response at the initial osseointegration process. Thus, the superior potential of superhydrophilic surfaces in enhancing osseointegration at early stages of bone formation may also enhance their load-bearing capa...

No remarkable events were observed during the surgical procedures and the subsequent healing period. The relative biomechanical performance of both experimental implant surfaces is illustrated in a representative graph of removal torque versus angular displacement. The removal torque, removal energy, and connection stiffness values are described in terms of mean, standard deviation, and 95% confid...
