Objective Evaluate the adhesive behavior of conventional and high‐translucent zirconia after surface conditioning and hydrothermal aging. Materials and Methods Conventional (ZrC) and high‐translucent zirconia (ZrT) specimens were divided into six groups: without surface treatment (ZrC and ZrT), air‐borne particle abrasion with 50‐μm Al2O3 sized particles (ZrC‐AO and ZrT‐AO), and tribochemical treatment with 30‐μm silica modified Al2O3 sized particles (ZrC‐T and ZrT‐T). Zirconia specimens were treated using an MDP‐containing universal adhesive and bonded to two resins blocks with an adhesive luting cement. Microbar specimens with cross‐sectioned areas of 1 mm2 were achieved. Half of the microbars were subjected to hydrothermal aging. Bond strength was evaluated by microtensile bond strength test and statistically evaluated by the Weibull analysis. Results Roughness of the ZrC‐AO and ZrT‐AO groups were statistically higher. Bond strength analysis revealed higher bond strength for ZrC‐AO and ZrC‐T groups compared to ZrT‐AO and ZrT‐T, respectively. Mixed failure was the most frequent for the mechanically treated groups, while no cohesive failures were obtained. Conclusion Lower values of bond strength were obtained for the mechanically treated high‐translucent zirconia groups when compared to their conventional zirconia counterparts. Mechanical surface treatment significantly improved the bond strength to conventional and high‐translucent zirconia. Clinical Significance Mechanical surface treatment (air‐borne particle abrasion or tribochemical treatment) associated with the use of universal adhesives containing MDP could provide a durable bonding to conventional and high‐translucent zirconia.

Objective The unavoidable extraction of teeth in the esthetic area can be overcome through different treatment modalities. Recently, immediate implants appeared as a minimally invasive approach to resolving these cases; however, immediate implant loading is not always possible or indicated. In these cases, an innovative approach through customized healing abutments could be used to preserve the soft tissue contour, eliminating the need for reopening surgery and the use of provisional restorations to condition the mucosal contour. Clinical Considerations The present cases describe a simplified chairside approach to use customized healing abutments for immediate implants placed after tooth extraction in the anterior and posterior areas in order to maintain the soft tissue contours while reducing the clinical steps until delivering the final restorations. Conclusions This technique seems to be effective to guide the soft tissue healing around dental implants allowing a natural emergence profile with implant‐supported restorations, reducing the number of treatment steps. Clinical Significance The use of customized healing abutments prepares soft tissue for the prosthetic stage preserving its contours and eliminating the need for reopening surgery.
