Reconstruction of frontal bone using patient specific implant poly-ether-ketone-ketone via a lateral nasal/lynch incision

open access: yesOral and Maxillofacial Surgery Cases, 2023
Trauma to the craniofacial structures can result in both functional and aesthetic defects. Mucosa lines the frontal sinus outflow tract (FSOT) from the frontal sinus to the nasal cavity and any obstruction to the flow of mucus can lead to complications ...

Bonding behaviour of polyetherketoneketone to methylmethacrylate- and dimethacrylate-based polymers

open access: yesThe journal of adhesive dentistry, 2017
To investigate the impact of pretreatment and conditioning on bonding behavior of polyetherketoneketone (PEKK) to methylmethacrylate(MMA)- and dimethacrylate(DMA)-based polymers.1200 PEKK substrates (Pekkton ivory) were fabricated, air abraded (110 µm, Al2O3) and divided into 8 pretreatment groups as follows: 1. Visio.link (VL); 2. VL+ opaquer; 3. Pekk

A hybrid repair strategy for full-thickness cartilage defects: Long-term experimental study in eight horses. [PDF]

open access: yesJ Orthop Res
Abstract The objective of this study was to evaluate a non‐resorbable implant for the focal repair of chondral defects in eight adult horses with 12‐month follow‐up. The bi‐layered construct composed of a polycarbonate‐urethane‐urea biomaterial which was printed in 3D fashion onto a bone anchor was implanted into surgically created osteochondral ...
