Abstract: The present invention relates to orthodontic brackets designed for use with the deciduous teeth and method for its use. The brackets provide one or more debonding tabs which reduces the potential for damage to the deciduous tooth due to the application of excessive force during the debonding process. The small size of the brackets allow the brackets to fit available crown space on the deciduous teeth. Further the brackets are shaped to minimize mechanical forces applied to the deciduous teeth when engaged with an archwire. The bracket bases are shaped to conform to the morphology of the deciduous tooth crown surface thereby providing an optimal adhesive interface with the deciduous tooth. The deciduous brackets provide proper adhesion to avoid unwanted detachment of the brackets which often occurs when the use of permanent brackets is attempted on the deciduous teeth.

Abstract: An orthodontic direct bonding stent facilitates ideal positioning of physical attachments on a patient's teeth. Novel designs of direct bonding stents include uniquely configured windows for guiding placement of the attachments. Windows of reduced depth leave a majority of each attachment exposed beyond the stent for easy grip and manipulation, and use of a reduced height wall opposite the window-equipped wall eases removal of the stent without disruption of the adhered attachments. Use of elastomeric material at the window boundaries provides an improved seal with the tool for less adhesive splay, and inter-arch stents enable maxillary and mandibular placement with a single appliance. Lingual windows enable lingual placement of attachments for reduced visibility, and reduced wall thickness between adjacent windows provides improved mesial access to attachments.

Abstract: Non-food plant biomass is subjected hot-water extraction in a pressurized vessel at an elevated temperature up to about 250° C. without addition of reagents, to yield an aqueous extract containing hemicellulosic components and a lignocellulosic residue. The process leaves the lignocellulose substantially intact, but with the hemicellulosic content largely removed. The separated aqueous extract or liquor is concentrated and purified, and long-chain sugars are reduced into monomer saccharides. The lignocellulosic residue may be further processed, to yield a useful fibrous material that is highly resistant to sorption of water. This material may be used for composite materials that resist water degradation, or may be used to produce a higher thermal-yield, water-resistant fuel, or may be used as bioconversion feedstock for producing high-value, lignocellulosic derivatives.
