Table 1. Criteria for Fixation Scoring According to a Modified Drobnic Scoring.

Outline attachment	Area coverage	Scaffold integrity
Unchanged (5)	Unchanged (5)	Unchanged (5)
<25% (4)	<75–100% (4)	Minor deformities unrelated to fixation (4)
25–50% (3)	50–75% (3)	Minor cracks close to fixation site (3)
50–75% (2)	25–50% (2)	Fissures that jeopardize the fixation (2)
75–100% (1)	<25% (1)	Fissures and scaffold disorganization in outer area (1)
100% (0)	0% (0)	Fissures and scaffold disorganization in general (0)
	AFG	PCL
Outline attachment	1.7 ± 1.50	4.8 ± 0.41
Area coverage	2.7 ± 2.06	4.8 ± 0.41
Scaffold integrity	2 ± 1.79	4±0
Total score	6.3 ± 5.12	13.7 ± 0.82*

Scores show the difference between AFG and PCL efficacy in fixation. AFG shows high variability in results; overall efficacy for fixation with PCL was significantly higher than with AFG (*p < 0.05).

AFG, autologous fibrin glue; PCL, polycaprolactone.
