Effect of acid etching on tridimensional microstructure of etchable CAD/CAM materials
Full-ceramic restorations have been highly utilized in recent years because of their biocompatibility, improved mechanical properties, and optimal aesthetics [1]. Nowadays, a pre-sintered-ready-to-use format associated to computerized-aided technology (CAD/CAM blocks), has reached a strong position on dental ceramics market due to its convenience in reducing some laboratory steps besides maintaining materials positive characteristics [2]. In this regard, most materials available in pre-processed CAD/CAM block presentation are composites and glass-ceramics [2]. (Source: Dental Materials)

Optimization of the etch-and-rinse technique: New perspectives to improve resin –dentin bonding and hybrid layer integrity by reducing residual water using dimethyl sulfoxide pretreatments
Despite the evolution in adhesive dentistry over the past decades [1 –3], degradation of tooth-bonded interfaces [2] still contributes to the reduced long-term clinical success of adhesive restorations [4–6]. Currently, resin–dentin bonding relies on effective adhesive penetration into demineralized collagen matrix for proper hybrid layer formation [2,7]. The h ybrid layer is characterized by the creation of complex collagen-resin biopolymers aiming to provide a continuous and stable link between the bulk adhesive and dentin substrate [1,2].

Numerical fatigue analysis of premolars restored by CAD/CAM ceramic crowns
The purpose of this study was to estimate the fatigue life of premolars restored with two dental ceramics, lithium disilicate (LD) and polymer infiltrated ceramic (PIC) using the numerical method and compare it with the published in vitro data. (Source: Dental Materials)

Fabrication and characterisation of a novel biomimetic anisotropic ceramic/polymer-infiltrated composite material
Within both restorative dentistry and orthodontics there is a need for biomimetic materials that more closely approach the properties of natural tooth tissue. In restorative dentistry such a material could be used to restore tooth tissue lost through trauma or caries. A hybrid dental ceramic is commercially available [1,2] for use with CAD/CAM technology to mill dental restorations. In orthodontics such a material might be more aesthetic and have improved mechanical properties when compared with currently available aesthetic bracket materials. (Source: Dental Materials)

The effect of DLC-coating deposition method on the reliability and mechanical properties of abutment ’s screws
When prosthesis service involves sliding between metallic surfaces, as occurs in implant-abutment-screw contact area, severe wear (known as galling) may occur. Under loading conditions, materials with lower Young ’s modulus adheres locally to the contacting opposite surface and forms hard “galls” where wear initiates [1,2]. Any force that causes slippage between threads might reduce preload, which is supposed to maintain the joint clamped, potentially leading to screw failure [3]. Clinical findings hav e reported screw failure incidences of 10.8% [4] for single restorations over the years. (Source: Dental Materials)
