Resin-based composite restorations were introduced in dentistry about a half century ago as an esthetic restorative material 56 57 and composites increasingly are used in place of amalgam for the restoration of carious lesions 58 Composites consist of a resin matrix and chemically bonded fillers 42 They are classified according to their

:: RDE :: Restorative Dentistry Endodontics

Dental caries is one of the most common infectious diseases in which demineralization of hard tooth tissues occurs by the acid produced as a result of fermentation of carbohydrates by bacteria 1 At present the majority of carious teeth are restored with tooth-colored restorative materials and composite resins due to esthetic reasons In fact restorations with composite resins have

Bioprinting: From Tissue and Organ Development to in Vitro

Bioprinting techniques have been flourishing in the field of biofabrication with pronounced and exponential developments in the past years Novel biomaterial inks used for the formation of bioinks have been developed allowing the manufacturing of in vitro models and implants tested preclinically with a certain degree of success Furthermore incredible advances in cell biology

Zirconia dental implants: where are we now and where are

Dec 21 2016This composite exhibits a flexural strength twice that of yttria‐stabilized tetragonal zirconia polycrystal and greater fracture toughness In addition it is less subject to low‐temperature degradation In vitro experiments demonstrate promising results in terms of cell adhesion spreading and differentiation into bone‐forming cells 29 114

In Vitro Biofilm Formation on Titanium and Zirconia

Background: It has been hypothesized that zirconia might have a reduced bacterial adhesion compared with titanium however results from experimental studies are rather controversial The aim of the present study is to compare biofilm formation on zirconia and titanium implant surfaces using an in vitro three‐species biofilm and human plaque samples
