Across
  1. 2. Attracts water.
  2. 5. A material made from two or more constituent materials with different physical properties. Made of two parts; 1. Matrix and 2. reinforcement/filler. Polymer is the matrix and silica is the reinforcement.
  3. 6. Occurs when many individual monomers react to form covalent bonds and produce a bigger molecule called a polymer.
  4. 7. agents. compounds that bond the polymer to the silica.
  5. 10. wand. A hand-held wand that emits blue light which is used to harden the resin within a dental patient's mouth.
  6. 13. group. A functional group with one hydrogen and one oxygen atom.
  7. 14. bonds. A theory which describes chemical bonding.
  8. 15. fillings. Silver fillings. Alloys of mercury and other metals, such as silver, tin, or copper.
  9. 17. bonds. A chemical bond formed when electrons are shared between two atoms.
  10. 19. The ability of a biomaterial, device, or system to perform its desired function with respect to a medical therapy, without eliciting any undesirable local or systemic effects in the recipient or beneficiary of the therapy.

  1. 1. moiety. A branch extending from the backbone of a hydrocarbon molecule.
  2. 3. resins. White fillings that match the patient's tooth color. Resins are soft and can quickly dry/harden. They last a long time due to polymerization.
  3. 4. Used as adhesives. It is in super glue.
  4. 8. In dentistry; the process by which monomers are converted into polymers. Meaning many (many parts).a chemical chain of repeating monomers, which can link hundreds, thousands, or even millions of times.
  5. 9. based glass. Hydrophilic strong and clear glass produced when pure silica is fused at high temperature.
  6. 11. polymer. Having secondary polymer chains linked to a primary backbone.
  7. 12. polymer. A long continuous chain of carbon-carbon bonds with the remaining two valence bonds attached primarily to hydrogen or another relatively small hydrocarbon moiety.
  8. 16. Specific kind of small molecule capable of bonding together when exposed to light, heat, or pressure to form more complex polymers. Meaning part (one part)
  9. 18. Usually used as coupling agents. These silane molecules have a hydroxyl group on one end, and it condenses with a hydroxyl group on the surface of the glass to form an Si-O-Si link.
  10. 20. polymer. Formed when long polymer chains are cross linked together to create a three dimensional network.
