[The shortening of the ascending ramus of the mandible in a case of Class III malocclusion with open bite]. / Raccourcissement de la branche montante de la mandibule dans un cas de classe III avec béance.

With reference to a case reported here, the authors emphasize the importance of reducing the length of the ramus of the jaw in rather exceptional forms of gaps between the upper and lower jaws with an increase in the posterior height of the face. This procedure provides more stable results and the patient's gums are no longer revealed when smiling.
