Assessment of the density (i.e. quality) and alveolar height and width (i.e. quantity) of bone is key for success implant osseointegration 2:

  • density
    • edentulism typically leads to bone loss with resorption of the alveolar process typically affecting width before height
    • a number of Bone Quality Indices exist
      • Cawood and Howell
      • Lekholm and Zarb
      • Norton and Gamble
  • quantity
    • bone implant site needs to be at least 7-9 mm high and 5 mm wide 2,3
    • measurements should be taken every four sagittal oblique images through the region planned for implant
