In the case of tooth loss ideally it is replaced with a dental implant, because dental impants have several advantages such as restoring the function of mastication, increasing mobility and reducing pain. Nowadays after tooth extraction, dental implants are often implanted immediately, with the consideration of preventing mechanical loading, thus obtaining the stability needed for osseointergation of the implant. Titanium (Ti) implants are the most commonly used materials because they have good mechanical properties, biocompability, stable chemical, low toxicity, bioactivity and corrosion resistance. Various implant surface modification materials were carried out to improve implant integration, including hydroxyapatite (HA), antibacterial and BMP-2. These coatings to improve osseointegration and avoid implant infection, thus increasing the success rate of the implant. [ABSTRACT FROM AUTHOR]

This paper describes the numerical analysis of the wettability of the micro structured surfaces. The structure of the surface are the grooves created by the laser ablation. The main goal is to find the influence of the groove parameters on the wettability, specifically the contact angle. Ansys Fluent using the VOF method for multiphase simulation is used. In total, five different structures were investigated. The work started with the validation of the CFD methodology based on the experimental data for some structures. The CFD analysis was then performed. The fields of volume fraction as a results have been assessed to reach the contact angle value. The influence of structure parameters on the contact angle value were discussed. Finally, the recommendations for the optimal structure were defined. [ABSTRACT FROM AUTHOR]
