Objective: The aim of this study is a systematic review of the literature on the strength and long-term behavior of zirconia FPDs.
Methods: The literature search was performed using as the primary source the Medline database. Were also imposed a set of inclusion and exclusion criteria in order to narrow the search to differentiate the two distinct parts in which it was structured the review. In addition, MeSH terms were applied to further refine the choice of articles more relevant to the review. In the part of the review concerning the long-term behavior of zirconia fixed partial dentures were considered useful only those studies with a minimum follow-up of one year.
Results: The search provided a total of 813 articles, but only 25 were considered for the review because they were the only ones who satisfied search criteria. In particular, 13 items relate to the mechanical strength of zirconia prostheses and 12 regarding the long term behavior of zirconia FPDs. The resistance values also exceed the 2000 N while the survival rate reaches to almost 94%.
Conclusions: Based on this review, Zirconia FPDs can be considered reliable products in both the anterior and posterior fields with survival rates comparable to traditional metal-ceramic prostheses.

Behavior of YSZ (High YO Content) Layer on Inconel to Electro-Chemical Corrosion.
Materials (Basel)
January 2025
Faculty of Materials Science and Engineering, "Gheorghe Asachi" Technical University of Iasi, 67 Dimitrie Mangeron Street, 700050 Iasi, Romania.
The high yttria content of a stabilized zirconia (YSZ) (38 wt% YO) coating was deposited by atmospheric plasma spraying (APS) from Metco 207 powders on an Inconel 718 (Ni-based superalloy) substrate. As a metal coating connection, a layer of cermet powder (Ni-20% Al-410NS) was used before the ceramic layer deposition. The electro-chemical corrosion resistance of these materials was tested using Inconel cylinders with a diameter of 10 mm and a thickness of 1 mm, with and without the ceramic layer.

Materials (Basel)
January 2025
Department of Cariology and Endodontology, Peking University School and Hospital of Stomatology, Beijing 100101, China.
To assess the biomechanical behaviors of endodontically treated molars (ETMs) restored with endocrowns composed of different materials, forty mandibular molars were assigned to five groups (n = 8 each). Untreated molars constituted the control group (group C); the rest of the teeth that underwent root canal therapy were restored with endocrowns composed of polycrystalline ceramics (ST zirconia, UPCERA) in group ZR, lithium disilicate glass ceramics (UP.CAD, UPCERA) in group LD, resin-based nanoceramics (Hyramic, UPCERA) in group NC, and feldspathic ceramics (CEREC Blocs, Sirona) in group FC.

January 2025
Department of Restorative Dentistry - Endodontics, Faculdade de Odontologia de Piracicaba, Universidade Estadual de Campinas, Piracicaba, SP, Brazil.
Objectives: To investigate volumetric changes, in vivo biocompatibility, and systemic migration from eight commercial endodontic sealer materials in paste/paste, powder/liquid, and pre-mixed forms.
Materials And Methods: The sealers AH Plus Bioceramic, AH Plus Jet, BioRoot RCS, MTApex, Bio-C Sealer, Bio-C Sealer Ion+, EndoSequence BC Sealer and NeoSEALER Flo were studied. After characterisation by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), Raman spectroscopy and X-ray diffractometry (XRD), tubes were implanted in Wistar rats' alveolar bone and subcutaneous tissues.
Trauma-Induced Stress Distribution in Primary Incisors Restored With Preformed Zirconia Crowns: 3D Finite Element Analysis.
Dent Traumatol
January 2025
Division of Orthodontics and Dentofacial Deformities, Centre for Dental Education and Research, All India Institute of Medical Sciences, Delhi, India.
Background/aims: Preformed zirconia crowns have emerged as the preferred choice for restoring damaged primary incisors. However, they differ from natural teeth in their biophysical properties and can potentially alter the overall response of crowned teeth to a traumatic load. This in silico study aimed to compare the response of three different traumatic loading conditions for the (i) natural (M1) and (ii) zirconia-restored tooth models (M2) models.

Statement Of Problem: Translucent zirconias are promising materials for monolithic prostheses. However, information on their optical behavior after sintering and aging protocols is scarce.
Purpose: The purpose of this in vitro study was to evaluate the color and translucency of zirconia subjected to different sintering temperatures and aging.
