(B) After expansion, the diastema almost reaches 10 mm and will close partially afterwards. Let’s also note the improvement of the level of gingiva where the left lower incisor is located and which was slightly receding (blue arrows). To complete it, try to reinsert the key in the hole that is now at the back of the appliance (to do so, the key should be oriented toward the throat instead of the opening of the mouth). Growth is insufficient to correct such a problem. En raison de la pandémie de COVID-19, les dentistes et les orthodontistes ont dû prendre des mesures afin de limiter la propagation du virus dans leurs cliniques.

(A) 9.4-year-old boy – Posterior crossbite (yellow arrows) and mandibular shift to the right when the mouth closes. The upper right teeth are still tipped inward (arrows in B, D, E and F). (C) At the end of expansion, overcorrection that makes the upper teeth “go over” the lower teeth is seen on each side (more on the side where there was no crossbite to begin with). This should however return to normal after a few days in the vast majority of cases. Correcting this does not necessitate rapid palatal expansion. Maxillary expansion obtained without an expander or surgery in a young adult. When the mouth closes, the mandible is aligned with the upper jaw (blue arrow). Front (anteroposterior) view, a radiograph clearly shows the opening of the palatal suture indicated by yellow arrows. (A) Activation key with a plastic “handle” (blue). (A and C) 7-year-old young patient with a posterior crossbite (arrow) caused by a narrow maxilla. (B) When the permanent teeth have all erupted (13.5 years of age), the occlusion is esthetically and functionally acceptable and does not necessitate any other corrections. The patient (or the parent) must perform 1 or 2 screw activations per day, never more, until desired enlargement is obtained. You will however be able to go back to a “normal” diet after a short time. (D) Result after the closing of the diastema, the removal of the appliances and the posterior relapse of the overcorrection.
