Which appliance is a Frankel regulator in the context of vertical inocclusion treatment?

• A. Frankel type I functional regulator
• B. Frankel type II functional regulator
• C. Frankel type III functional regulator
• D. Bionator Balters type II

Answer: (B)

Frankel Regulator appliances work by using mucosal shields to modulate muscle pressures around the teeth and jaws, guiding eruption and jaw position rather than forcing changes with fixed bite mechanics. For vertical occlusion issues, the regulator that is designed to influence and normalize vertical dimension through these muscle-driven changes is the Frankel Regulator Type II. Its design targets the vertical relationship by allowing appropriate eruption and settling of the posterior teeth while balancing lip and cheek pressures, making vertical control achievable within the Frankel family. The other Frankel variants are tailored for different sagittal or dental relationships, and a different appliance (Bionator Balters type II) is not a Frankel regulator.
