Characteristics of the two reference point indentation devices
| BioDent | OsteoProbe | |
|---|---|---|
| Method of use | Mounted* | Hand-held |
| Manufacturer suggested research target | Pre-clinical | Clinical |
| Reference probe | Three types | None |
| Test probe size | ~370 microns | ~ 370 microns |
| Probe tip radius | 2.5 microns | <10 microns |
| Overcoming soft tissue | Scraping, preload, preconditioning | Unknown |
| Loading force** | User defined (2–10 N) | 40 N |
| Loading rate | 40 N/sec | 120,000 N/sec |
| Loading cycles | User defined (up to 20) | 1 |
| Preconditioning | Optional in cycle number and force | During 10N preload |
| Data visualization during test | Force versus distance plots and data | Raw (unnormalized) BMSi value |
*
Although the majority of studies have used the system mounted, data does exist using the BioDent as a hand-held device(17).
**
Biodent uses a true load-control feedback system while Osteoprobe generates a load using a spring-based system without feedback.
