Evaluation of the Color of Zirconia in Different Substrates of Osseointegrated Implants, Thickness of Materials and Types of Resin Cements.

To evaluate the impact of surface conditioning of titanium, zirconia thickness, and cement type on the final color of zirconia luted to the titanium. A total of 192 grade 5 titanium specimens with the final dimensions 10 mm × 10 mm × 2 mm were fabricated and subjected to four different surface conditioning including, that is, sandblasting, etching, and anodization. In addition, 192 zirconia specimens with the same dimensions as the titanium specimens but altered thicknesses of 0.

What comes first: teeth or face? Recommendations for an interdisciplinary collaboration between facial esthetic surgery and dentistry.

Objective: The aim of the present study was to provide recommendations in order to facilitate communication between dental professionals and surgeons who are collaborating in the field of dentofacial esthetics.

Clinical Considerations: Smile esthetics are beyond the scope, both of the surgeons who are collaborating with facial esthetics and of the dentists, as a wide range of treatment options from both sides is available. It can be difficult for the surgeon or the dentist that first comes in contact with the patient to conduct an individualized global treatment plan, in order to find out how the various phases of the treatment can be sequenced, as a workflow for an efficient interaction between facial surgery and dentistry still does not exist in the scientific literature.

Predictability and outcome of titanium color after different surface modifications and anodic oxidation.

To investigate the predictability and the outcome of surface modification techniques, including anodization. Four surface modification techniques were evaluated in this in-vitro study: sandblasting (S), polishing+anodizing (PA), sandblasting+anodizing (SA), polishing+etching+ anodizing (PEA). Color coordinates L*, a* and b* were collected using a spectroradiometer.

Color stability of polymer-infiltrated-ceramics compared with lithium disilicate ceramics and composite.

Objective: To investigate the color stability of hybrid ceramics and to compare it to composite and lithium disilicate ceramics.

Materials And Methods: One hundred eighty samples were fabricated and processed with a semiautomatic grinding and polishing device (final step: 1200 grit). After thermocycling, samples were immersed in a staining solution (five subgroups: water, red wine, curry, black tea, cola) for 4 weeks.

Factors affecting the early failure of implants placed in a dental practice with a specialization in implantology - a retrospective study.

Background: To evaluate early failure and possible risk factors for failure of dental implants placed under practice-based conditions.

Methods: To clarify the research question, anonymized data from 106 patients with 186 dental implants were analyzed. The presence of sucessful healing (yes/no) at the time of incorporation of the final prosthesis was assessed.

Short-term performance of implant-supported restorations fitted in general dental practice: A retrospective study.

Purpose: The objective of this retrospective clinical study was to evaluate the short-term performance of implants and implant-supported dental restorations (single crowns, fixed/removable dental prostheses, and overdentures) and to identify risk factors for prosthetic complications under the conditions of general dental practice.

Materials And Methods: De-identified data extracted from electronic patient records were analyzed to clarify the research question. Patient-related variables and implant- and suprastructure-related variables were documented for each patient.
