Autosomal dominant prognathism

This trial tests a modified jaw surgery technique, called low sagittal medial ramus osteotomy, for people with severe bite misalignment (skeletal Class II or III malocclusion). The procedure aims to reposition the jaw with fewer complications than the standard surgery, particular…

This study follows children aged 9–12 with an underdeveloped upper jaw (maxillary retrognathism) causing a reverse bite. They receive standard interceptive orthodontic treatments, such as facemasks or other appliances, to guide jaw growth. Researchers track changes in jaw positio…

This study compares the Invisalign Palatal Expander (IPE) with the Rapid Palatal Expander (RPE) in children aged 8–12 who have a narrow upper jaw and an underbite (skeletal Class III). Participants will wear a facemask after expansion. Researchers use 3D X-rays to measure changes…

This study compares two ways to correct an underbite (Class III malocclusion) in children whose jaws are still growing. One method uses a facemask attached to a tooth-borne expander, while the other uses a chin-plate anchored to the bone with small screws. Researchers will measur…

This study will compare custom 3D printed splints made at the hospital with those made by outside companies for jaw surgery. The splints help surgeons align the teeth and jaws correctly during the operation. Researchers want to see if the in-house splints are faster to get, cheap…
