Table 1a: Histomorphometrical Ongrowth: Tissue Area Fractions on Implant Surface

Surface Fraction New Bone Mean % (SD) Bone Graft Median % (IQR) Fibrous Tissue Median % (IQR)

Control 17 (6.3) 0.0 (0.0 - 0.1) 0.7 (0.0 - 1.9)
Periosteum 14 (3.6) 0.0 (0-0 - 0.0) 3.8 (0.5 - 5.0)

Periosteum-Control 3 (0.0; 6.0)
Students t-test p = 0.05
Wilcoxon p = 0.13 p = 0.12

New bone is presented as mean with standard deviation (SD) and the absolut difference between treatment groups as mean difference with 95% confidence interval (CI). Bone graft and fibrous tissue are presented as median with interquartile range (IQ).
