Pages 118-119, Language: EnglishSilva, Nelson R. F. A. / Ferencz, Jonathan L. / Silva, Guilherme C.Intraoral scanners have been used to capture data for the design and subsequent manufacture of dental restorations and also for registering color clinical images. Scanners can capture datasets for future use and comparisons. This manuscript describes the potential of using software algorithms to superimpose 3D images captured at different times to calculate dimensional changes at the click of a button in various dental fields. 3D patient monitoring, with the advance of artificial intelligence and its built-in capacity for data analyses, will allow dentists and researchers to calculate volumetric changes and predict potentially adverse clinical outcomes.

Ideally, the decision should be based on scientific evidence, but often these decisions are based on economic considerations or influenced by the experience of a trusted peer. The purpose of this paper is to describe the influence of implant neck features (shape and surface) and abutment connection (diameter that matches or is smaller than the implant's platform) on hard and soft tissues around single-tooth implants placed into healed ridges with adequate hard and soft tissue thickness. In an effort to reduce the number of variables, only two-piece implants fully placed at bone level or beneath were taken into consideration. The goal is to provide additional guidance for clinicians on the decision-making and implant-selection processes.

A. / Bonfante, Estevam A.Der Beitrag schlägt ein Klassifikationssystem für keramische und keramikähnliche Restaurationsmaterialien unter Berücksichtigung einer neuen Materialklasse vor. Die neue Klassifikation ordnet keramische Restaurationsmaterialien in drei Familien: Glasmatrix-, polykristalline und Kunststoffmatrix-Keramiken. Außerdem werden die vom Hersteller angegebenen klinischen Indikationen der verschiedenen Materialien genannt, die Verarbeitungstechniken werden überblicksartig aufgeführt und es wird angegeben, ob die Materialien als Gerüstwerkstoffe oder für monolithische Lösungen verwendet werden.

DOI: 10.11607/ijp.4244, PubMed ID (PMID): 25965634Pages 227-235, Language: EnglishGracis, Stefano / Thompson, Van P. / Ferencz, Jonathan L. / Silva, Nelson R. F. A. / Bonfante, Estevam A.Classification systems for all-ceramic materials are useful for communication and educational purposes and warrant continuous revisions and updates to incorporate new materials. This article proposes a classification system for ceramic and ceramic-like restorative materials in an attempt to systematize and include a new class of materials. This new classification system categorizes ceramic restorative materials into three families: (1) glass-matrix ceramics, (2) polycrystalline ceramics, and (3) resin-matrix ceramics. Subfamilies are described in each group along with their composition, allowing for newly developed materials to be placed into the already existing main families. The criteria used to differentiate ceramic materials are based on the phase or phases present in their chemical composition. Thus, an all-ceramic material is classified according to whether a glass-matrix phase is present (glass-matrix ceramics) or absent (polycrystalline ceramics) or whether the material contains an organic matrix highly filled with ceramic particles (resin-matrix ceramics). Also presented are the manufacturers' clinical indications for the different materials and an overview of the different fabrication methods and whether they are used as framework materials or monolithic solutions. Current developments in ceramic materials not yet available to the dental market are discussed.

A.Ziel dieses Übersichtsberichts ist es, mehrere In-vitro- und In-vivo-Studien zum Ergebnis von einteiligen Zirkonoxidimplantaten zu diskutieren und zwei klinische Fälle vorzustellen, in denen Prototypen von Zirkonoxidimplantaten eingesetzt wurden. Ein Schwerpunkt hierbei liegt auf den möglichen wissenschaftlichen und klinischen Bedenken, die es im Hinblick auf die funktionellen, biologischen und ästhetischen Langzeitergebnisse gibt.
