Across
  1. 5. - Materials placed outside of the mouth on replicas of prepared teeth. They are then fitted and cemented to the teeth
  2. 7. popular in the past; Today, replaced hybrid ionomer cements and resin cements are used since they have better physical properties
  3. 11. - Restorations of root caries since they bond to the root better than composites and release fluoride
  4. 12. Using acid etchant during placement and occlusal interference can cause ________ following a placement of composite restorations.
  5. 13. bases are applied in _______ layers (stronger)
  6. 14. As Young's modulus states: the greater the volume of the filler, the more ________ the restoration
  7. 19. Tip for porcelain: use _________ scalers, if improperly applied, can chip and craze margins of esthetic materials
  8. 21. - Materials that can be placed directly into the cavity preparation or onto the tooth surface by the clinician without first being constructed outside that mouth. Composite resin, glass ionomer, hybrid ionomer, compomer
  9. 24. resin that is added in hybrids so that they could have properties of glass ionomers and composites; They are stronger, less soluble, more polishable and more wear resistant; They release fluoride and have thermal expansion similar to tooth structure
  10. 27. __________ is used to capture image of the tooth preparation directly from the tooth or the die and it is stored in the computer
  11. 29. porcelain jackets are used mainly on ________ incisors
  12. 31. Resin matrix absorbs (___sameword___) from oral cavity over time. The greater the resin content, the more (___sameword___) is absorbed. (___sameword___) causes expansion of the composite over 1st week of placement
  13. 33. help contain the restorative material within the preparation during placement and to develop natural contours and areas
  14. 38. - The restoration is fabricated by milling a device that shapes the ceramic block into the restoration as instructed by the computer program. Advantage: fabricated immediately. Disadvantage: not a precise fit
  15. 39. - An effective technique for shade matching
  16. 41. Liners, bases, or temporary cements that contain _______ are contraindicated since they inhibit set of resins
  17. 42. - Glass ionomer is “sandwiched” between the tooth and another restorative material (composite). Glass ionomer seals better on the root while composite is more wear resistant and esthetically pleasing
  18. 45. ________ will transmit hot and cold temperatures like natural tooth structure
  19. 48. flowables have ________ viscosity, therefore adapt to cavity walls
  20. 49. are placed interproximally and hold the matrix band against the tooth to seal the gingival margin
  21. 50. After dentin bonding any form of moisture should be eliminated until restoration is completed. If contaminated, re-etch for (___time____) (follow manufacturers instructions)
  22. 51. - Adding an unfilled resin to the surface of the composite after finishing and polishing. Purpose is to reseal margins opened by polymerization shrinkage
  23. 53. - Used to rebuild missing dentin within the cavity preparation
  24. 54. - Self-cured, tooth-colored fluoride releasing restorative materials
  25. 55. - Cover the dentin for pulpal protection from temperature changes, chemicals within other restorative materials and from etchants
  26. 56. - Shrinkage that occurs when material is cured although recent research indicates that material does NOT shrink toward the light.
Down
  1. 1. Older composites appear radiolucent on radiograph since they do not have metals (in xray check the cavity margins – if its very well defined is a restoration; if not, it’s a carie)
  2. 2. Composite should be placed in small increments about _______ thick to minimize polymerization shrinkage and allows curing light to penetrate thoroughly
  3. 3. - Thin layers of esthetic materials bonded to the front portion of the teeth usually anterior teeth
  4. 4. - Excellent esthetic appearance, Biocompatible, Low wear rate, Stain resistance, Potential to fracture, Difficulty repolishing it after adjustments
  5. 6. acidulated fluorides can etch porcelain surfaces –________ (1.23%) is not used for porcelain (acid phosphor fluoride)
  6. 8. liners are applied in _____ layers (weaker) closer to the pulp
  7. 9. - Will capture an image of the tooth and upload it to a personal computer for processing. Shade information can be sent to the dental laboratory via email, disk, or by printout
  8. 10. - Well tolerated by surrounding soft tissue, Minimal allergy to components of the material
  9. 15. - Used for custom shade cases. The forked arrangement of the tubes simulates natural direction of daylight illumination
  10. 16. - Smaller particles therefore easier to load in the resin matrix (advantage), weaker, less wear resistance
  11. 17. - Highly viscous, Contain high volume of filler particles, Stronger and more wear resistance, Used on posterior teeth, Marketed as substitutes for amalgam due to their stiffness
  12. 18. - Low viscosity resins, Vary in filler content, Same as flowable composites and Prevent dental caries in pits and fissures of teeth
  13. 20. Composites (___sameword___) faster than amalgams; Microfills and flowables (___sameword__) faster than more heavily filled materials
  14. 22. - Heavily filled composites, Used in badly broken down teeth requiring crowns, High strength, Bonded to tooth structure to minimize bacterial leakage
  15. 23. - Metals such as lithium, barium, or strontium are added to filler to make the restoration more opaque when viewed on a radiograph
  16. 25. Composites with _______ filler particles are stronger in both tension (pulling) and compression (bearing) than microfilled particles
  17. 26. - Appear similar to natural teeth since they are fluorescent. They are also opalescent since they appear bluish when light reflects off them and orange-yellow when light passes through them. They do not have an opaque layer to hide metal
  18. 28. - Filler content is 75% and 80% by weight, Contains macrofillers and microfillers, High strength, highly polished, used for anterior and posterior teeth
