Investigation of the change in the degree of Frankfort mandibular plane angle after levelling the curve of spee in different malocclusion groups.

Background And Objectives: The curve of Spee is a naturally occurring phenomenon in the human dentition. Leveling the curve of Spee can affect the Frankfort-mandibular plane (FMP) Angle and thus the lower anterior facial height. This study examined the degree of change in FMP angle after leveling the curve of Spee in different malocclusion groups.

Application of the OPG in the Prediction of Unfavorably Angulated Canines: An Original Study.

Introduction: Achieving a correct occlusion depends heavily on the axial inclination of the teeth, particularly the maxillary anteriors, which have the longest crowns. This study, which expanded the use of angular measures to the mandible, was created to determine the prevalence of adversely angulated canines using orthopantomograms.

Methods: A sample of 200 people between the ages of 18 and 25 was chosen and separated into two groups based on the degree of crowding; one group served as the control group while the other, which experienced severe, crowding, served as the study group.
