Objective: To assess the dental and skeletal changes resulting from correction of a deep bite using Invisalign (Align Technology, Santa Clara, CA, USA).Methods: This is a retrospective case series study which analyzed pre and post treatment cephalograms for 37 adult deep bite patients. Each patient was treated by one, experi-enced clinician using the same treatment protocols. Nineteen variables, ten linear and nine angular. The Wilcoxon analysis was used to determine if there was a significant dif-ference in pre and post treatment variables. Results: Statistically significant differences (P<0.05) occurred for 14 of 19 variables. These include a decrease in Overjet (-0.97 mm), decrease in overbite (-4.07 mm), extru-sion of the upper first molar (0.47 mm), intrusion of the upper incisor (-0.67mm), extru-sion of the lower second molar (1.01 mm), lower first molar (1.20 mm), lower second premolar (1.70 mm), and lower first premolar (1.74 mm), intrusion of the lower incisor (-1.88 mm), proclination of lower incisor, (4.09 ̊), and increase in SN-MP (0.54 mm). A decrease in anterior occlusal plane (AOP) was also statistically significant. Conclusions: Invisalign is an effective treatment modality for correcting dental deep bites through posterior extrusion and anterior intrusion. Minimal skeletal changes are seen when correcting deep bites with Invisalign.

Introduction: The purpose of this retrospective study is to evaluate the maxillary and mandibular expansion achieved with Invisalign First (Align Technology, San Jose, CA) in growing children. Methods: Clinical stereolithography (STL) models of 32 patients in the mixed dentition stage, treated with the Invisalign First, were extracted from the ClinCheck software and analyzed in Dolphin imaging (version 11.95 Premium, Chatsworth, Calif) at three timepoints: T1 (initial records), T2 (virtual outcome prediction), and T3 (achieved outcome). The recorded measurements included: upper and lower primary intercanine and permanent intermolar width, upper and lower primary intercanine and permanent intermolar gingival width, upper arch …

Efficacy Of Lower Incisor Intrusion Using Clear Aligners, Cason Roberson
All ETDs from UAB
Objective: The primary objective of this study is to evaluate pre and posttreatment lateral cephalometric radiographs on patients treated with Invisalign by the same orthodontist where lower incisor intrusion was prescribed and to determine the amount of true lower incisor intrusion achieved during treatment. Methods: This retrospective case series study included 48 patients with an overbite exceeding 2mm, who were treated with Invisalign clear aligner therapy, and whose Clincheck treatment plan included lower incisor intrusion. The mean age of the study group was 27 years with 14 (29%) of the subjects being male and 35 (71%) being female. The mean …
