The introduction of zirconia in dentistry partly solved the need for better mechanical properties of metal-free protheses. In spite of the high strength, the veneering porcelain on zirconia is brittle and fractures easily. Besides that, zirconia also presents low bond strength to resin cement. Another disadvantage is its low temperature degradation under certain conditions of moisture and…
According to the benefits derived from international partnerships with professors of high level institutions, the Postgraduate Program in Restorative Dentistry of the Institute of Science and Technology, Unesp São José dos Campos started and preserves a scientific partnership since 2005 with the professor doctor Mutlu Özcan. Currently, the professor acts as a teacher and head of the Depar…
Silica infiltration of zirconia used for biomedical application has already been proved to prevent low temperature degradation. In the present study, we will investigate the mechanical and bonding properties (to resin cements and porcelain) of a zirconia infiltrated by silica using a sol-gel method, which has the benefits of being simple, low-cost and cold process.Lately, zirconia infiltr…

The study aims to evaluate the adhesion of resin cement to soda-lime glasses with and withoutsilver, through the shear test. 60 square slices of 5Y-PSZ zirconia (Katana UTML, KurarayNoritake, Japan) and 30 slices of leucite-reinforced feldspathic ceramic (IPS Empress CAD,Ivoclar Vivadent, Liechtenstein) will be made. Subsequently, the zirconia samples will besintered following the protoco…
In two-stage implant systems, the prosthetic abutment is retained to the implant through fixation, which may generate a micro-gap between the abutment and the implant. This crack may be favorable to bacterial colonization, affecting the mucous seal and, consequently, causing peri-implantitis. Within this perspective, this study intends to develop an antimicrobial agent (glass with silver)…
Zirconia, when applied clinically in dentistry, is exposed to the oral environment, which makes it highly prone to superficial adhesion of biofilm and microbial proliferation. Silver has a proven antimicrobial action and, in association with zirconia, could confer some antimicrobial activity to this ceramic. If silver is applied inside a very smooth glass, it can also reduce the biofilm's…
Dental zirconias are known for their excellent mechanical properties, biocompatibility and corrosion resistance, but it is a great challenge for them to have satisfactory aesthetic characteristics. After so many advances, we currently find in the market multi-layered dental zirconias with different yttria concentrations, polychromatic shapes and multiple clinical indications. However, the…
Over the years, dentists have opted for the use of ceramics, knowing that they can provide highly esthetic rehabilitations. Hybrid ceramic is a type of ceramic combined with composite resin, made from CAD/CAM technology, being advantageous for the dentist in a way of easy to adapt and/or modify, having a modulus of elasticity similar to the resilient modulus of the dentin. The application…
The study aims to evaluate the adhesion of the pigment layer/stratified porcelain to ultra translucency zirconia (third generation), under different firings in the absence or presence of the extrinsic pigment layer through the shear test. 60 slices of zirconia (10 x 10 x 3 mm) and 30 cylinders (Ø = 3, mm and 3 mm in height) will be made over a layer (or not) of pigmentation followed by th…

Associated with the process #2021/03878-3, in which the analysis of fatigue life, mechanical and antimicrobial properties of 5Y-PSZ zirconia abutments with antimicrobial glass is proposed, the present project applies for one year research as an internship in the University of Mississippi Medical Center. Zirconia is frequently used in prosthetic rehabilitation because of its mechanical pro…
Dental ceramics and specially zirconia is one of the top choices nowadays as restorative materials in prosthetic rehabilitations. After so many advances in material sciences, zirconias are no longer just a white and opaque material, but now translucent and even polychromatic and multi-layered, with multiple clinical indications. Multilayered models can be found with both translucency grad…
Associated with the process #2021/00748-1, in which the analysis of mechanical and antimicrobial properties of ultra-translucent zirconia with different vitreous coating is proposed, the present project applies for a six-month research internship in the National University of Singapore. Zirconia is a ceramic material commonly used in dentistry because of its high fracture toughness value,…
The present study will evaluate the failure probability of translucent zirconiarestorations submitted to several surface finishes. 220 preparations will be made in G-10 to receive 1.0 mm thickness restorations made of YZ HT (N=100, n=20), KATANA UTML (N=100, n=20) or IPS EMAX CAD (n=20). Each zirconia group will be divided into five subgroups according to the surface finishing: Polishing …
The aim will be to analyze the interfacial energy for fracture (fracture toughness) of the bond between resin cement and zirconia. The comparison will be made between infiltrations made by the sol-gel method with quick immersion in silicic acid, in TEOS or the glass infiltration of a graded zirconia (slurry). Therefore, brazil nut specimens will be infiltrated by the following methods: Si…
