Table 1.
Bone histomorphometric parameters.
| Parameter | Units | Description/Equation |
|---|---|---|
| Bone-implant contact (BIC) | % | The percentage of implant length at which there is direct bone-to-implant contact, without intervening tissue, along the total length of the implant |
| Bone volume (BV) | % | Ratio of mineralized and un-mineralized bone volume to the total tissue volume estimated from the analyzed section |
| Bone area (BAr) | mm2 | The total bone area of the analyzed section |
| Bone perimeter (BPm) | mm | The total perimeter of bone in the analyzed section, including void surfaces and excluding artificial edges |
| Node termination (NTm) | - | End points in a trabecular network or free ends |
| Trabecular pattern factor (TbPF) | - | (perimeter 1 − perimeter 2)/(area 1 − area 2)a |
