The posterior tip improves access in tight spaces due to its short 14mm tip height. It also boosts patient comfort during scanning. The posterior tip is not for general scanning; rather, it should be used for specific regions in the mouth, such as distal molar surfaces, and for patients with limited bite openings, trauma, or TMJ.  It also improves access to subgingival areas of the preparation. 

The posterior tip is approximately the size of a turbine head without the bur in place.

Key Point: Most clinicians perform initial scans with the standard or side-oriented tip and then change to the posterior tip to scan more challenging regions of interest.
