Comparing the Prognostic Utility of Vertebral and Endplate Bone Quality Scores for Cage Subsidence Following Single‐Level Anterior Cervical Discectomy and Fusion: A Retrospective Analysis

Orthopaedic Surgery, EarlyView.
MRI‐derived bone quality metrics are reliable predictors of cage subsidence following ACDF. Their implementation may be used to guide surgical planning and improve outcomes. ABSTRACT Objective Cage subsidence following anterior cervical discectomy and fusion (ACDF) is linked with poor bone quality.

Dynamic Behaviour of a Continuous Heat Exchanger/Reactor after Flow Failure [PDF]

, 2008
The intensified technologies offer new prospects for the development of hazardous chemical syntheses in safer conditions: the idea is to reduce the reaction volume by increasing the thermal performances and preferring the continuous mode to the batch one.

Emerging locally delivered antimicrobial and immunomodulatory approaches for the prevention/treatment of peri‐implant diseases

Periodontology 2000, EarlyView.
Abstract Peri‐implant diseases are dysbiosis‐mediated inflammatory disorders that occur in susceptible hosts. Antimicrobials and immunomodulatory agents therefore might be pertinent as adjunctive measures in the treatment of such disorders. The aim of this narrative review was to examine the existing evidence and assess the effectiveness of emerging ...

Comparison and Analysis on Mechanical Property and Machinability about Polyetheretherketone and Carbon-Fibers Reinforced Polyetheretherketone [PDF]

Materials, 2015
The aim of this paper is to compare the mechanical property and machinability of Polyetheretherketone (PEEK) and 30 wt% carbon-fibers reinforced Polyetheretherketone (PEEK CF 30). The method of nano-indentation is used to investigate the microscopic mechanical property. The evolution of load with displacement, Young’s modulus curves and hardness curves

Zirconia, titanium, and polyetheretherketone implant abutments show equal long‐term clinical success—A systematic review and network meta‐analysis

Periodontology 2000, EarlyView.
Abstract Hundreds of millions of people have one or more missing teeth. Consequently, a substantial number of patients undergo implant therapy each year. However, technical complications and soft tissue inflammation associated with the implant abutment or the type of restoration can lead to bone loss and, ultimately, implant failure.
