Skeletal class III malocclusion

This trial tests whether a new intraoral device, the Ertty Gap III, can correct skeletal Class III malocclusion (underbite) in growing children aged 9–12 as effectively as the standard facemask therapy. The study measures changes in jaw alignment using X-rays before and after tre…

This trial tests two devices, a face mask and the Ertty Gap appliance, in 30 growing patients with a deficient upper jaw (skeletal Class III malocclusion). Each patient receives one of the two devices to pull the upper jaw forward. Researchers use cone beam CT scans and 3D cephal…

This study tested two methods to correct underbite (skeletal Class III malocclusion) in 14 growing children. One group used a traditional tooth-borne anchor with a face mask, while the other used a palatal plate with a face mask. The goal was to see which approach better moves th…

This study looks at whether certain genetic variations are linked to a type of underbite called skeletal Class III malocclusion. Researchers will collect saliva samples, facial photos, and X-rays from people with and without the condition to compare their DNA. The goal is to iden…

This study looked at a treatment called "Surgery-First" for people with a severe underbite (skeletal Class III malocclusion). Instead of wearing braces before surgery, patients had jaw surgery first to fix the bone problem, then braces afterward. Researchers studied 60 patients u…
