Widening a narrow upper jaw with bone-anchored expander
Part of Mouth & dental clinical trials.
This trial tests a device to widen a narrow upper jaw using small anchors in the bone. It is for adolescents and adults who have a crossbite and a narrow upper jaw caused by bone structure, and who have never been treated before.
