Periosteal Augmentation of Allograft Bone and its Effect on Implant Fixation

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).
