Medial Patellofemoral Ligament Reconstruction With Quadriceps Tendon Using an Expanding PEEK Anchor

open access: yesArthroscopy Techniques
The medial patellofemoral ligament (MPFL) represents one of the main stabilizers of the patellofemoral joint. Rupture of the MPFL has been reported in 95% to 100% of patients with acute patellar dislocation.

Systematic Review Evaluating the Influence of Veneering Design on the Clinical Outcome of All‐Ceramic Implant‐Supported 3–4 Units and Full Arch Fixed Dental Prostheses

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To systematically assess survival, failure, and complication rates of all‐ceramic implant‐supported monolithic and micro‐veneered FDPs (i‐FDPs) in partially/completely edentulous patients compared to veneered restorations. Materials and Methods An electronic search identified prospective clinical studies on all‐ceramic i‐FDPs with at

Polyether Ether Ketone / Carbon Nanotube Composite Fibres

open access: yesChemical Engineering Transactions, 2017
Polyether ether ketone (PEEK), a thermoplastic polymer with excellent temperature stability and mechanical properties, is modified with carbon nanotubes (CNT). Then it is processed to fibres to study the influence of CNT on the mechanical properties, the

Toughening of BIS maleimide resins: Synthesis and characterization of maleimide terminated poly(arylene ether) oligomers and polymers [PDF]

open access: yes
Amine functional poly(arylene ether) sulfones were previously reported. Herein, the chemistry was extended to amorphous poly(arylene ether) ketones because of their higher fracture toughness values, relative to the polysulfones.

Preparation of high performance SPEEK/Cloisite 15A nanocomposite membrane via advanced membrane formulation method [PDF]

open access: yes, 2014
Sulfonated poly (ether ether ketone) (SPEEK)/Cloisite 15A® nanocomposite membranes were prepared via solution intercalation method. For better dispersion of nanoclay in the polymer matrix, the solution intercalation method was modified and a ...

Long‐term periodontal and peri‐implant tissue stability under supportive therapy

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Supportive periodontal and peri‐implant maintenance therapy is strongly associated with improved long‐term retention and stability of natural teeth and dental implants. Lack of regular professional follow‐up after initial therapy is a major risk factor for disease recurrence and tooth or implant loss.
