The Correlation of Hounsfield Unit, Vitamin D3 and the Insertion Torque of Dental Implant during Normal and Undersized Preparation Protocol for Different Bone Densities.

The placement of implants by an adapted drilling technique in sites with poor bone density is beneficial in enhancing primary implant stability. the HU is positively and significantly correlated with stability ISQ, and insertion torque. There is a high recommendation to utilize the HU as a dependent and novel determinant to select a specific protocol for preparation, so whenever we get a HU of 528.5 +/- 26.5 and below we should obtain an under-preparation protocol.
