Early Effects of Orthognathic Surgery on Periodontal Phenotype: A 6-Month Prospective Clinical and Radiographic Evaluation

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.

Relationship Between Soft Tissue Volume and Gingival Phenotype: a Novel Classification System

Different classifications to describe alveolar ridge defects have been published over the past years but no single classification has been developed concerning soft tissue volume around teeth or dental implants. Moreover, while several studies investigated the effect of various augmentation techniques and materials on soft tissue volume change and volume stability there is a real gap of knowledge regarding how to evaluate the available soft tissue volume and when to consider it sufficient or deficient which would definitely improve clinical decision making and treatment planing. Therefore, our primary aim was to assess the application of a novel classification system based on the correlation between buccal soft tissue volume and gingival biotypes and, also to assess the sensitivity of such novel method.
