The goal of this observational study is to learn how the health and thickness of the gums and supporting bone around the teeth change over 6 months in adults having jaw surgery to correct the bite. The main questions it aims to answer are:
* Do gum and tooth-support measurements change from before surgery to 1, 3, and 6 months after surgery?
* Do CT scan-based measurements of the tooth-supporting…
The goal of this observational study is to learn how the health and thickness of the gums and supporting bone around the teeth change over 6 months in adults having jaw surgery to correct the bite. The main questions it aims to answer are:
* Do gum and tooth-support measurements change from before surgery to 1, 3, and 6 months after surgery?
* Do CT scan-based measurements of the tooth-supporting bone change over the same time period?
Participants will:
* Have a gum check-up (periodontal examination) before surgery and at 1, 3, and 6 months after surgery.
* Have CT scan-based measurements (CBCT) taken at the same time points for study assessment.
