Comparing two jaw surgeries for severe underbite
Part of Bones, joints & muscles, Genetic & congenital, Mouth & dental clinical trials.
This trial compares two surgical techniques to fix a severe underbite caused by a small lower jaw. One method uses a special cut in the jawbone and a piece of hip bone to lengthen it, while the other uses a different jawbone cut to move the jaw forward. It will help find which approach works better for people with this condition.

This trial is studying a method to rebuild part of the lower jaw using a blood-supply bone replacement, so you can later get dental rehabilitation. It’s for adults who need a sizable, tumor-free jaw bone reconstruction and who can safely undergo surgery.
This study tests a new way to reposition the lower jaw to improve bite problems in people with certain skeletal misalignments. It aims to see how well the technique works and how it affects the nerves and healing.
This study looks at how the way the upper jaw is positioned during corrective jaw surgery affects the joint's healing over time. It may help people with a specific type of underbite who are already planning to have both upper and lower jaw surgery.
This study looks at two different ways of doing jaw surgery to see which one gives better stability and healing. If you are already planning to have jaw surgery, this study may help improve how well your jaw stays in place after the procedure.
This trial compares a computer-guided technique versus a free-hand method to widen a narrow jawbone in the lower back mouth. If you have a thin jawbone and need dental implants, this study tests a more precise way to create enough space for them.
This trial tests a new way to cut the jawbone during surgery to see if it helps the bone pieces fit together better. It might help patients needing jaw surgery.
