Accuracy Of Dolphin Imaging Software Vs Quickceph Studio In Prediction Of The Extraction Treatment Outcomes Of Class Ii Malocclusion In Adult Patients: A Retrospective Study, Mostafa Ahmad Hashem, Hala Munir Abdel Majeed, Sameh Mohamed Talaat

Future Dental Journal

This study aimed to evaluate the accuracy of Dolphin Imaging Software and QuickCeph Studio in predicting the soft tissue profile following extraction treatment of Class II malocclusion. The study included 32 Class II patients aged 14 to 30 years who had previously undergone orthodontic treatment with extraction of first premolars. The accuracy of both software applications was evaluated using preoperative and postoperative lateral cephalometric X-rays and extra-oral photographs to compare the predicted outcomes with the actual post-treatment outcomes. Results: there was no significant difference between posttreatment and predicted regarding dolphin software while there was only a significant difference between posttreatment …

Skeletal And Dental Effects Of The Carriere Motion Appliance™ In Non-Growing Class Ii Patients: A Cephalometric Study, Anna Cathlyn Giles

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background and Objectives: Dental and skeletal Class II discrepancies are commonly associated with orofacial disharmony, and therefore appear in orthodontic clinics frequently. Class II correction for adults is generally limited to camouflage treatment with extractions, Class II elastics, Class II correctors, distalization, or orthognathic surgery in severe cases. The orthodontic field is constantly innovating to find efficient and effective means to correct class II malocclusions. The Carriere Motion Appliance TM was introduced in 2004 as an effective “distalizing” appliance to be used as a non-extraction approach to Class II correction for adolescent and adult patients. Recent clinical evidence suggests that …

Comparative Cephalometric Study Between Class Ii Patients Treated With Herbst Appliance And Patients Treated With Mara, Mona Meky

ABSTRACT

Comparative cephalometric study between Class II patients treated with Herbst appliance and patients treated with MARA

Mona Meky, D.D.S.

Background and Objectives: Functional appliances have been used for over 100 years in orthodontics to correct Class II malocclusions. The Herbst and the MARA appliances have different designs that may enhance mandibular growth. Recent clinical evidence has questioned whether they really have a lasting influence on facial growth and that the effects of these appliances were mostly dentoalveolar rather than skeletal. The objective of this retrospective comparative study was to compare the dental and skeletal changes between Class II division …

Perception Of Profile Appearance As Judged By Peers Using 3d Video Imaging, Megan G. Schuler

Theses and Dissertations

The purpose of this study was to investigate the social perceptions of subjects with differing lip position and facial convexity in three dimensions. A 3dMD camera (3dMD, Atlanta, GA) was used to capture 3D images of 9 subjects’ faces. The images were altered to have ideal lip position and ideal convexity, ideal lip position and Class II convexity, Class II lip position and ideal convexity, and Class II lip position and Class II convexity. 400 laypersons rated their perceptions of the subjects’ athletic ability, popularity, leadership, and intelligence on a VAS scale. Subjects with ideal lip position relative to the …

Treatment Effects Of The Mandibular Anterior Repositioning Appliance (Mara) And Conventional Orthodontic Mechanics On Temporomandibular Joint Morphology: A Comparison Using Cone Beam Computed Tomography, Brenton E. Glassell

Theses and Dissertations (ETD)

Introduction: An ongoing debate exists in orthodontics about the amount of condylefossa remodeling and growth seen in Class II patients using functional appliance therapy. Some clinicians and researchers have found that that the use of functional appliances increases the amount of condylar growth and subsequent Class II skeletal correction; others believe that the mandible has a preset amount of growth and that conventional orthodontics will result in a similar amount of condylar growth to functional appliance therapy. Purpose: The aim of this study was to compare condylar remodeling in functional appliance treatment using the mandibular anterior repositioning appliance (MARA) to …

The Long-Term Stability Of Class Ii Cases Treated In A Private Practice Using A Straightwire Appliance: A Dental Cast Analysis, Lina K. Kulkarni

Theses and Dissertations (ETD)

Achieving long-term stability after orthodontic treatment is a major challenge for orthodontists. The previous literature shows that relapse occurs at a considerable magnitude. The purpose of the present study was to determine the amount and type of long-term, posttreatment relapse that occurs in a homogeneous group of patients treated by a single experienced orthodontist in a private practice setting. Dental casts from a sample of 30 Class II division 1 Caucasian females treated without extractions were evaluated at pretreatment (mean age = 13.1 years), posttreatment (mean age = 15.9 years) and recall (mean age = 28.3 years) to determine the …
