  1. The values are given corresponding to zones (Z1 = adjacent to implant, Z2 = far from implant). All implants show similar values with no significant differences found between groups. Values measured for granulation tissue correspond with those found in normal bone, while the relatively high percentage of new bone matrix indicates new bone formation and activity of osseointegration. The largest difference is seen for the old bone matrix indicating that bone resorption as an answer to the original surgical trauma is more intensive close to the implant. Also the granulation tissue is less in the zone farther away from the implant
  2. *Z1 = close to implant Z2 = far from implant
