Assessment of Vertical Pattern in Correlation With Third Molar Inclusion : A 3D CBCT Analysis
Assessment of Vertical Pattern in Correlation With Third Molar Inclusion : a 3D CBCT Analysis
Central Hospital, Nancy, France
80 participants
Dec 1, 2024
OBSERVATIONAL
Conditions
Summary
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.
