Zirconia bond strength durability following artificial aging: A systematic review and meta-analysis of in vitro studies.

The present study systematically reviewed the literature regarding the bond strength durability of zirconia ceramics to resin-based luting cements after application of different bonding protocols and aging conditions. Electronic searches in PubMed, Scopus, and Web of Science databases were performed for relevant literature published between January 1st 2015 and November 15th 2022. Ninety-three (93) English language in-vitro studies were included.

Evaluation of marginal/internal fit of fixed dental prostheses after digital, conventional, and combination impression techniques: A systematic review.

Advances of digital technology are rapidly adopted in dental practice. This systematic review aimed to collect evidence on the accuracy of fit of different types of fixed dental prostheses (FDPs) fabricated through digital, conventional, or combination impression techniques. Data collection was based on the guidelines of the preferred reporting items for systematic reviews and meta-analyses (PRISMA).

Effect of Diclofenac and Simvastatin on Bone Defect Healing-An In Vivo Animal Study.

Non-steroidal, anti-inflammatory drugs and statins are two widely prescribed drug classes that affect bone formation. The aim of this study was to elucidate the effect of diclofenac and simvastatin in artificial bone defect healing. One hundred and forty-four male Wistar rats were used, and the specimens were divided into groups, with respect to the route of drug administration and the type of defect healing (with or without collagen membrane), and subgroups, with respect to the study duration (2, 4 or 8 weeks).

Tooth preservation vs. extraction and implant placement in periodontally compromised patients: A systematic review and analysis of studies.

Purpose: The aim of this systematic review was to identify studies with a minimum of 5-years follow-up, reporting on the management of periodontally compromised teeth with either extraction and subsequent implant placement or teeth preservation with conventional periodontal treatment and application of regenerative procedures. The outcomes of these two approaches, based on clinical and radiographic data and the incidence of tooth- and implant-loss, were also investigated.

Material And Methods: A systematic search for studies reporting on clinical and radiographic outcomes of periodontal treatment or replacement of periodontally compromised teeth with implants was conducted in 3 electronic databases, followed by a hand-search in 8 journals.

Effect of different zirconia surface pretreatments on the flexural strength of veneered Y-TZP ceramic before and after in vitro aging.

Purpose: The investigation of zirconia core surface pretreatments on the flexural strength of bilayered zirconia ceramics before and after artificial accelerating aging.

Methods: Ninety bar-shaped specimens were manufactured from Yttria Stabilized Tetragonal Zirconia Polycrystal (Y-TZP) and divided in three groups depending on zirconia surface pretreatment before veneering: layering with liner, pretreatment with silane-containing gas flame (SGF) with the Silano-Pen device and alumina air-abrasion. Half of the veneered specimens in each group (n=15) underwent artificial accelerating aging.

Screwmentable implant-supported prostheses: A systematic review.

Statement Of Problem: Screwmentable prostheses were developed to combine the benefits of screw retention and cement retention. However, data are limited on the clinical performance of this type of prosthesis.

Purpose: The purpose of this systematic review was to collect scientific evidence on screwmentable prostheses and evaluate their long-term clinical behavior.

Load-bearing capacity of implant-supported, tooth-supported, and combined zirconia-fixed dental prostheses.

Aim: The aim of this in vitro study was to investigate the influence of heterogeneous abutment supports on the load-bearing capacity of zirconia posterior four-unit fixed dental prostheses.

Methods: A total of 18 specimens were fabricated and divided into 3 groups. Specimens in the first group were supported by teeth with simulated periodontal resilience, in the second group by the combination of a tooth with simulated periodontal resilience and an implant, whereas in the last group by implants only.

Load-bearing capacity of artificially aged zirconia fixed dental prostheses with heterogeneous abutment supports.

Aim of this in vitro study was to investigate the effect of artificial ageing and differential abutment support on the load-bearing capacity of zirconia posterior four-unit fixed dental prostheses (FDPs). Thirty-six FDPs were fabricated using CAD/CAM technology and divided into three groups. Specimens in the first group were cemented onto tooth analogues with simulated periodontal resilience, in the second group onto a dental implant and a tooth analogue, but in the third group only onto implants.
