Official Title: Correlation Between Buccolingual Dental Inclination and Bone Thickness After Orthodontic Decompensation in Patients With Class III Dentofacial Deformities

Brief Summary: The correlation between tooth inclination and bone thickness and the comparison between thickness measurements and buccolingual inclination before and after dental decompensation will be evaluated through tridimensional images in individuals with class III dentofacial deformities.

Detailed Summary: Class III dentofacial deformity is associated with important functional, psychological and aesthetic changes and thus individuals affected by this type of deformity are motivated in seeking treatment. The sample will consist of three-dimensional images of 40 individuals with Class III dentofacial deformities. From these images generated by CBCT scans, the buccolingual inclinations of all teeth and maxillo-mandibular alveolar bone thickness in three different heights will be measured (3, 6 and 8 mm) from the cementoenamel junction through the Dolphin 3D® program. The 3D scans of the sample will be evaluated in two stages: the initial stage and after dental decompensation at the end of pre-surgical orthodontic phase. Pearson correlation test will be used to verify the relationship between tooth inclination and bone thickness. The thickness measurements and buccolingual inclination will be compared between treatment times (initial and pre-surgical) using paired Student t-test.

Current Primary Outcome: Change in tooth inclination and bone thickness after tooth decompensation [ Time Frame: 12 months after the begginning of orthodontic treatment, prior to orthognathic surgery ]

Original Primary Outcome: Positive correlation between tooth inclination and bone thickness after tooth decompensation prior to orthognatic surgery [ Time Frame: 12 months after the begginning of orthodontic treatment ]
