This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Objectives The interest in ceramic dental implants made of yttria-stabilized tetragonal zirconia polycrystals (Y-TZP) or alumina toughened zirconia (ATZ) has increased in recent years. However, in the light of aging, corrosion, and potential impurities of zirconia ceramics, the material composition of these implants and the associated term "metal-free" is persistently questioned. Thus, the present study aimed to conduct an elemental analysis of commercial zirconia dental implants to specify their elemental composition and to identify contaminants. Methods Nine commercial zirconia dental implant systems and corresponding material samples were analyzed using inductively coupled plasma-mass spectrometry (ICP-MS) and optical emission spectrometry (ICP-OES). Results While the elemental composition was dominated by the main components Zr, Y and Al (in ATZ samples), all investigated samples contained impurities with Hf and contamination with alkali and alkali earth elements (Na, K, Mg, Ca), essential trace elements (e.g. Fe, Cu, Zn) but also potentially noxious metal elements (e.g. Ni, Cr). Furthermore, ultra-trace level contamination with the radionuclides U-238 and Th-232 was found in the majority of samples. Significance The results indicate that, although all the investigated Y-TZP and ATZ dental implants meet the currently relevant ISO standards and manufacturer's specifications, from an elemental point of view, they are not devoid of metals. Due to the lack of a universal definition and thresholds for the term "metal-free", the question of whether the examined zirconia dental implants can be holistically classified as "metal-free" or not remains a controversial, philosophical one

This book was released on 2019 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, dental implant downsizing has become one major trend in modern implantology but it requires the development of materials with improved mechanical resistance. Never- theless, titanium and its alloys, the gold standard dental materials, seem to have reached a plateau in terms of mechanical properties, which may limit their use for such strategy. Amorphous titanium-based metallic alloys are a unique class of materials showing high mechanical and fatigue properties, good corrosion resistance and a relatively low Young's modulus, which thus make them potential candidates for the realization of such-small diameter implantable pieces in substitution to polycrystalline titanium. There is also a growing trend to use ceramic implants in dentistry. In particular, the white color of Yttria-Tetragonal Zirconia Polycrystal (Y-TZP) materials combined with their unique transformation toughening ability have made them materials of choice for the realization of metal-free, aesthetic dental implants. However, ageing of Y-TZP ceramics in aqueous environments may be a concern and even if strongest than many other ceramics, Y-TZPs still remain elastic-fragile with a sensitivity to the presence of defects. Various Ceria-doped based zirconia ceramics have been developed over the past years, in particular during two recent European projects led by MATEIS and Anthogyr. These materials may be highly resistant to flaws with a considerable toughness and an unusual transformation- induced ductility. This unique combination of properties makes them potential candidates for the realization of ceramic dental implants, as an alternative to 3Y-TZP. Within this PhD work, the potential of the two materials for (i) the realization of less invasive implants to replace titanium alloys on one hand, and (ii) aesthetic and more reliable ceramic implants as alternative to 3Y-TZP on the other hand, will be studied. The first part of this work will be focused on Ti40Zr10Cu36Pd14 metallic glass. The potential of this amorphous alloy for future implantable devices fabrication is assessed in terms of ion release in relevant media, corrosion resistance, biocompatibility and fatigue resistance, with a comparison to the benchmark conventional biomedical grade Ti alloys. The role of Sn and Si alloying elements on the overall properties of the alloy will be also analyzed. The second part of this work will deal with a new Ce-TZP based composite. Mechan- ical characterization and fatigue resistance will be evaluated and compared to 3Y-TZP material. Furthermore, the transformation-induced plasticity of this composite will be better understood, thanks to original experiments, in order to validate its reliability and its absence of potential damage under stress. All the results may open new perspectives in the future of dental applications.
