 Introduction: Dento-alveolar and skeletal effects of orthopedic treatment have always been the subject of controversial scientific discussions. The aim of this article is to describe and discuss a clinical case with skeletal Class III malocclusion treated with Frankel-III appliance in the following manner.

1)  To cephalometrically evaluate the skeletal, dental and soft tissue changes following therapy with Frankel’s function regulator -III (FR-III).

2) To evaluate arch width and apical base width changes with Frankel’s function regulator –III (FR-III).

Conclusion: It was found that the FR-III appliance restricts mandibular growth and stimulates forward movement of maxilla.


Key words: Skeletal Class III, FR-III appliances, soft tissue profile, apical base width.
