Neuronal differentiation and tissue engineering strategies for central neurous system injury repair

BMEMat, EarlyView.
This review outlines tissue engineering advances for central nervous system (CNS) injury treatment, focusing on three core components: seed cells, inductive factors, and scaffold materials, with evaluation of their respective strengths and limitations. Tissue engineering for CNS injury repair.

Doing, Feeling, Meaning And Explaining [PDF]

, 2011
It is “easy” to explain doing, “hard” to explain feeling. Turing has set the agenda for the easy explanation (though it will be a long time coming). I will try to explain why and how explaining feeling will not only be hard, but impossible.

Laser Densification of Extruded Dental Porcelain Bodies in Multi-Material Laser Densification (MMLD) Process [PDF]

, 2004
In this study commercial dental porcelain powder was deposited via slurry extrusion and laser densified to fabricate dental restorations in a Multi-Material Laser Densification (MMLD) process. The processing conditions for laser densification of single

Bi-directional freezing affords elastic and durable artificial tooth enamel

Communications Chemistry, 2022
Tooth enamel possesses outstanding viscoelasticity as well as stiffness — a combination of properties often considered a trade-off. Now, a bi-directional freezing method affords a biomimetic composite with mechanical properties superior to those of enamel.

Digitally guided corticotomy using a customized surgical template (Suya corticotomy utility template): A technique report

Clinical Advances in Periodontics, EarlyView.
Abstract Background Precise control of corticotomy lines is critical in surgically facilitated orthodontic therapy. The Suya method is traditionally performed freehand, which introduces risks of root damage and procedural inconsistency. A digitally guided protocol may address these limitations by enhancing safety and technical predictability. Methods A

Advances in Triboelectric Nanogenerators With Rotating Structure

Carbon Energy, EarlyView.
The rotating TENG has been widely studied for its superiorities of simple structure, high efficiency, and stable output. This review introduced the four different principles of rotating TENG and offered a thorough summary for performance and application research through three‐level classification. Importantly, the current existing problems, challenges,

The role of polymerization cycle and post-pressing time on tooth movement in complete dentures

Brazilian Oral Research, 2009
This study analyzed the influence of polymerization cycle and post-pressing time on tooth movement in complete dentures. Forty maxillary complete dentures were fabricated and randomly assigned to 8 groups (n = 5); the polymerization cycle (conventional ...

Convolutional neural network for automated tooth segmentation on intraoral scans

BMC Oral Health
Tooth segmentation on intraoral scanned (IOS) data is a prerequisite for clinical applications in digital workflows. Current state-of-the-art methods lack the robustness to handle variability in dental conditions.

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

Developmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Composition, Phase Structure, and Corrosion of Nickel-Free and Nickel-Containing Stainless Steel Orthodontic Wires [PDF]

, 2014
Stainless steel wires have long been used in orthodontics. The austenitic stainless steel used in orthodontics contains approximately 18 wt% chromium and 8 wt% nickel. Nickel improves the corrosion resistance and helps maintain the austenite structure of
