Table 1 Evaluation of SBS scoring of the bone stock by Gruen zones
Score | Bone stock evaluation |
|---|---|
+ 4 | no damage or complete regeneration (density and thickness) |
+ 2 | moderate damage: decreased thickness or density or defects < 10 mms |
0 | severe damage: decreased thickness and density or defects > 10 mms |
-2 | major damage in density and thickness or cortical lysis |
