    摘要: A self customizable dental appliance adapted to lie within the mouth of a person including occlusal pads with a connecting arch or a u-shaped style base with upstanding labial and lingual walls. The appliance is formed of a semi-crystalline polyolefin polymer or crystallizable blend. In one embodiment, the appliance is formed of elastomeric propylene-ethylene polypropylene, optionally including high density polypropylene. An optional occlusal lifting pad can be used in the self-customizable dental appliance.

    摘要: According to an aspect of the invention, a polymerized form of formaldehyde is available in granular form containing a polymerized form of formaldehyde, such as paraformaldehyde, a buffer, such as sodium phosphate dibasic anhydrous, and a stabilizer, such as hydroxymethyl cellulose, or hydroxypropyl methyl cellulose. When added to an aqueous solvent, the paraformaldehyde can dissolve in alkaline solution, and depolymerizes into a formaldehyde solution containing a stabilizer. Optionally a second member of the buffer pair or another buffer or pH adjuster can be used. The stabilized depolymerized formaldehyde solution is then ready for use, or can be modified by addition of other substances, such as sodium phosphate monobasic monohydrate. Additionally, an additional buffer may be included in the granular mixture to increase the rate at which the solid dissolves and depolymerizes.
