Using Cold Plasma As A Surface Treatment With Peek Dental Implant: A Case Series”., Mohamed Dohiem, Hebatalla Mahmoud El Afandy

Future Dental Journal

Background: Polyetheretherketone (PEEK) is a material that can be used instead of normal titanium implants. PEEK is considered inert and biocompatible, however, it has been shown to possess low surface energy and that leads to decreased osteointegration with bone, Recent researches have focused on increasing the bioactivity of PEEK by modifying the surface by chemical and physical means such as plasma treated surfaces.

Intraoral Characterization Of Monolithic Ceramics: The “Triple R” Protocol, Amr S. El-Etreby

Future Dental Journal

A successful life like dental ceramic restoration should be able to blend harmoniously with the adjacent natural teeth. This could be achieved by mimicking and duplicating the natural teeth color, translucency, as well as the surface characterization of natural teeth. Shade matching is an important and a difficult task in mimicking natural teeth that usually leads to unreliable and inconsistent results. Still, a small percent of human teeth shade cannot be matched by available commercial shade guides. The presence of a chair side CAD/CAM system in the dental office eliminates the presence of laboratory steps and hence saving time and …
