Peri-implantitis continues to be one of the major reasons for implant failures. We propose a new approach incorporating MTA into Zirconia surfaces with Nd:YAG laser and investigate biological response peri-implant cells as well microbiological response. Discs stabilized Yttria Titanium were produced according 4 tested groups: textured coated (Zr MTA); Textured); discs Ti ). Contact profilometry was used evaluate surface roughness. Human osteoblasts, gingival fibroblasts S. oralis cultured on...
Barium titanate (BaTiO3) piezoelectric ceramic may be a potential alternative for promoting osseointegration due to its properties similar bone electric potentials generated in loading function. In this sense, the aim of vitro study was evaluate cellular response human osteoblasts and gingival fibroblasts as well impact on S. oralis when contact with BaTiO3 functionalized zirconia implant surfaces properties. Zirconia discs were produced poling (piezo activation) performed. Osteoblasts (hFOB...
Adding a biological apatite layer to the implant surface enhances bone healing around implant. Objective This study aimed characterize mechanical properties and test human gingival fibroblasts behavior in contact with Zirconia Titanium bioactive-modified materials. Methodology 6 groups were considered: (Ti6Al4V), Ti6Al4V 5% HA ßTCP, (YTZP), YTZP ßTCP. For each group, we produced discs using novel fabrication method for functionally graded materials, under adequate conditions etching...
Abstract Yttria‐stabilized zirconia (YSZ) is being proposed as an alternative material to Titanium for dental implants due its aesthetic and biocompatibility properties. However, it yet define the optimal surface treatment improve YSZ bioactivy. Texturization a promising approach, but biological role of patterned surfaces in cell cultures be determined. Thus, cellular behavior osteoblasts fibroblasts contact with groove‐texturized was investigated. discs were groove‐textured by conventional...

Botulinum toxin is a protein that the anaerobic bacterium Clostridium botulinum produces and can be applied for various purposes, from aesthetics to rehabilitation procedures, such as in cases of patients who have facial paralysis. The objective this work describe how paralysis treated with toxin, its contraindications, side effects, well benefits. aim also procedure capable providing quality life by recovering asymmetry. This basic research qualitative approach. As procedure, bibliographic...
Background Zirconia is a potential alternative to titanium for dental implants, however, there need the improvement of surface treatment protocols enhance its bioactivity. Several strategies have been described achieve this aim, including manufacture modifications that increase roughness using laser, micro-machining or treatments as sandblasting and acid etching (SB-AE). The benefits laser graving versus milling are not yet known. Aim/Hypothesis In vitro comparison osteoblast response...
Background Although titanium remains the material of choice for dental implants, zirconia is increasingly regarded as an alternative due to its esthetical and biological properties. However, there a need improve response bone surfaces. Several strategies have been described, such surface modifications based on manufacture meso-sized patterns enhance cell response. Aim/Hypothesis In vitro evaluation osteoblast surfaces with sandblast-acid etching (SB-AE) additional grooves or pore textures...

Background: Zirconia is a promising material for dental implants. Laser surface treatment has been considered an innovative texturing technique to improve bioactivity and, consequently, early osseointegration. However, the optimal texture characteristics and influence of microtopography on cellular behavior are yet be determined.
