Patients with an Angle Class III malocclusion are generally
treated by orthodontics with or without orthognathic surgery.
A literature search revealed very few articles describing solely
the prosthodontic treatment of a Class III malocclusion, as it is
rarely used as a treatment modality in these cases. The purpose
of this article is to show the effects and benefits of an increase
in the vertical dimension of the occlusion (VDO) in patients
with a Class III malocclusion. An increase in the VDO causes a
clockwise rotation of the mandible, thereby increasing the
reverse overjet. This phenomenon allows a prosthodontic
treatment of the Class III malocclusion in some patients.
Therefore, proper diagnostic procedures, careful planning, and a simulation of the final appearance by wax-up and mock-up are mandatory when choosing the modality of prosthodontic
treatment. A case with a Class III malocclusion,
treated solely by prosthodontic means, is presented. The
implemented prosthodontic treatment included the correction
of the crossbite and the occlusal plane, the reestablishment
of the anterior and canine guidance as well as the
provision of a stable occlusion and enhanced facial and
dental esthetics. It is proposed that an increase of the VDO
should be taken into consideration whenever a patient
with a Class III malocclusion is prosthodontically treated.
