Abstract:
Does a technique using pre-adjusted brackets offer orthodontists advantages or stumbling blocks in their efforts to improve control of vertical dimension over the course of full-banded treatment? If pre-adjusted brackets are always helpful in hyper-divergent cases, how can orthodontists utilize them to the fullest extent? The author attempts to respond to these questions in a two-part article. The first section deals with the specific cephalometric and mechanical characteristics of hyper-divergent skeletal Class I and Class III cases by analyzing two clinical examples: the objective being to control the hyper-divergence. The second part is devoted to skeletal Class II malocclusions in which the hyper-divergence must be reduced in order to stimulate optimal anterior rotation of the mandible.

Properties of the Root Locus
To determine if a point lies on the root locus, the criterion involves the sum of angles contributed by all poles and zeros to that point. Specifically, this sum must be an odd multiple of 180 degrees. The gain at any point on the...

Construction of Root Locus
For positive gain values, the root locus exists on the real axis to the left of an odd number of finite open-loop poles or zeros. The root locus starts at the open-loop poles and traces the paths of the closed-loop poles as the gain increases.
