Официальное название
Assessment of Vertical Pattern in Correlation With Third Molar Inclusion : a 3D CBCT Analysis
Обзор
The objective is to compare the sagittal and vertical skeletal parameters of patients with an impacted third molar. Patients will be analyzed according to their skeletal characteristics: skeletal class (sagittal direction) and facial skeletal typology (vertical direction). The inclusion characteristics of third molars will also be analyzed, to see the links between typology and inclusion. The principal hypothesis is no significant difference in third molar inclusion patterns in relation to skeletal divergence.
Подробное описание
The study is a non-interventional (observational) research involving the human person, research on existing data (retrospective study) and samples dealing with dentofacial orthopedics.
This study analyzes third molar inclusion patterns in relation with the skeletal characteristics, sagittal and vertical typology.
This is a comparative retrospective study of radiographs in three dimensions before any orthodontic treatment. The patients studied are at Bacchetti CS stage 5 (adults), and the third molar must be at least at Nolla stage 6 of formation.
There is no control group but there are subgroups depending of the skeletal characterics.
