Perceived Efficacy Of Extrusion Of Maxillary Lateral Incisors With Aligners, Mason T. Bates
Theses and Dissertations
Purpose: To assess the perceived efficacy of aligners (Invisalign, Align Technology Inc) at performing extrusive movements of maxillary lateral incisors, determine a general threshold of when a maxillary lateral incisor is not extruding as predicted and requiring intervention, evaluate the frequency and methods of intervention to achieve the predicted extrusion, and to evaluate any related differences between orthodontists and general dentists, and between clinicians having treated various numbers of patients with Invisalign in the past 12 months.
Methods: An original 18-question survey was sent by mail to a randomized and geographically proportionate selection of orthodontic specialists (N = …
Treatment Effects Of Incisor Positioning On Anterior Tooth Display, Scott J. Eberle
Treatment Effects Of Incisor Positioning On Anterior Tooth Display, Scott J. Eberle
Theses and Dissertations
The purpose of this study was to determine the effect of changes in maxillary incisor position on anterior tooth display (ATD) in adult (n = 21) and adolescent (n = 38) orthodontic patients. The effects of anterior-posterior, vertical, and angular changes of the maxillary central incisor position during orthodontic treatment were evaluated relative to changes in the amount of ATD measured from pretreatment (TI) and posttreatment (T2) lateral cephalometric radiographs of existing patient records.Results showed a significant relationship between starting ATD and ATD change during treatment for both adults (P = ,006) and adolescents (P
