Developed in partnership with Dr. Trevor Nichols, the Nichols Smile Arc Bracket Gauge – Lower Arch is designed for vertical bracket placement on the mandibular dentition during direct bonding.

Prescribed bracket heights follow Dr. Nichols’ protocols, providing precise, reproducible incisal or occlusal edge-to-slot measurements for consistent vertical bracket positioning.

Its compact profile minimizes mouth opening during measurement, helping maintain isolation and efficiency throughout bonding.
