Resistance to this movement is called viscosity.1 The flow characteristics of a material are the basis for the science of rheology.12 The correlation of shear stress and shear rate determines the behavior of the material and can be described as either Newtonian (where viscosity is not affected by shear stress)—of which water is an example—or non-Newtonian. 112 VOLUME 3 No. (2013) Contact Angle and Wetting The contact angle is the angle formed by the adhesive with the adherend at their interface. Surface tension & wetting in dental materials 2. In the present study, we evaluated bone apposition to a modified sandblasted/acid-etched (modSLA) titanium surface, as compared with a standard SLA surface, during early stages of bone regeneration. It was also transferred with success to hyperhydrophilic dental implants. 112 VOLUME 3 No. Ultra-hydrophilicity is lost in pure water but is conserved in liquids such as dry methanol or dry ethanol and also in the dry state through protection by a fine dissication layer. & Oshida, Y.

The wettability of 18 dental impression materials, commercially available, during their working time was investigated using the contact angle method, as a good wettability is desired to obtain a high fidelity impression. Elasticity. ResearchGate has not been able to resolve any citations for this publication. Implants., 26, 1256-1266. Higher contact angles (e.g., greater than 90°) mean lower wetting (i.e., more hydrophobic). Since it could not be excluded that an impregnation of the sample with water infl uenced the measurements, a baseline correction was introduced to account for any force increase due to change in sample weight between immersion and emersion. If the molecules of the adhesive are attracted to the molecules of the adherend as much as or more than they are to themselves, the liquid adhesive will spread completely over the surface of the solid, and no angle will be formed. - "Comparison for Physical and Mechanical Properties of Dental Rubber Impression Materials" Statement of problem: Some elastomeric impression materials are hydrophobic, and it is often necessary to take definitive impressions of teeth coated with some saliva. Modified PVS materials and one of the hybrid materials are more hydrophilic than traditional PVS materials when measured with water. A water contact angle which is as high as possible determines whether the material can be used for such applications. The sample was equally divided into casts from male and female subjects with an age range from 18 to 25 years. Mechanical and Corrosion Properties of Laser Surface-Treated Ti13Nb13Zr Alloy with MWCNTs Coatings. 5. Wetting of dental impression compounds. (2011) Int. Oral.

[Current requirements for polymeric biomaterials in ear, nose and throat medicine]. The SI unit of stress or pressure is the pascal, which has the symbol Pa, that is equal to 1 N/m 2, 0.00014504 lbs/in 2 in Imperial units, or 9.9 × 10 −6 atmospheres. Wetting times for reaching contact angles of 0° ranged from 364–395 ms. From these pilot experiments we conclude that measurements of ultrahydrophilicity/ superhydrophilicity (θ ≤ 10°, no hysteresis), which do not consider imaginary contact angles, should be re-evaluated.

Harder materials more resistant to abrasion. The simultaneous determination of the microscopic roughness factor leads to the conclusion that ultra-hydrophilicity is not due to an increase in roughness factor, but is probably due to surface chemical changes. Surprisingly, it was found that contrary to current standards for measuring ultrahydrophilicity, an imaginary receding contact angle up to 15i° was found in all samples. The contact angle of VPES was 44.84º, which was lower than 54.76º for PE. 12. This method can record an adaptation “contact angle” immediately after mixing.

PBS) an exsiccation layer composed of specific ions is formed on the dry metal oxide surface exerting the stabilizing effect. Two methods of contact angle measurement are applied on screw type dental implants composed of titanium with different surfaces: The standard Wilhelmy method (dynamic measurement) and an extended sessile drop method (static measurement), where droplets with a volume in the picoliter range are generated. The resin nano-ceramics material is the most hydrophobic dental crown material with a contact angle of 60.5[degrees], while zirconia is the most hydrophilic material with a contact angle of 20.4[degrees]. In this case the finding that contact angles can be expressed as complex numbers offers the possibility of a much refined analysis beyond zero degrees of rough ultra-/superhydrophilic, (now called hyperhydrophilic), metal surfaces, which play a distinct role in dental and orthopedic implantology. Within the ophthalmic industry, the best example of a biomaterial is a contact lens, which is worn by approximately 125 million people worldwide.
