Summary

A mandibular plane angle of 19.4° sits inside its ideal range of 15.0 to 22.0°, scoring 10.0 for Neels Visser's lower jaw. The measurement assesses the steepness or flatness of the lower jaw relative to the horizontal plane, and a balanced angle avoids extremes that can point to hyperdivergent growth or occlusal misalignment. Neels's value is almost identical to those of Adrian Grenier and Mattia Basso, both at 19.4°, and it is higher than 45% of the men on the wiki, while 50% of them measure inside the same ideal range. At the extremes, KL Rahul records the highest value at 38.1°, and Jack Doherty the lowest at 1.0°. See his Gonial Angle and his full Harmony breakdown for more.
