Efficacy Of Temporary Fixed Retention Following Comprehensive Orthodontic Treatment, Mark J. Owens
Efficacy Of Temporary Fixed Retention Following Comprehensive Orthodontic Treatment, Mark J. Owens
Theses and Dissertations (ETD)
Instability of the occlusion is a common problem following orthodontic treatment. The purpose of the present research was to evaluate posttreatment relapse at long-term recall (> 10 years) in cases (A) treated with temporary fixed mandibular retention plus Hawley retainers compared to (B) a similar group retained with just removable retention (standard Hawley type retainers alone). Fixed retainers were removed after having been in place for about 2.5 years. Following this period, use of removable retention was left up to the discretion of the patient in both groups. Data consisted of orthodontic records of 166 American whites, all of whom …
A Survey Of Treatment Characteristics In A University-Based Graduate Orthodontic Program, A. Brian Anderson
A Survey Of Treatment Characteristics In A University-Based Graduate Orthodontic Program, A. Brian Anderson
Theses and Dissertations (ETD)
While there are a few national surveys on malocclusion in the U.S., few reports characterize actual orthodontic patients and their treatments. The purpose of this study was to describe the patients and their treatment at a university based orthodontic department, namely the University of Tennessee Health Science Center, Memphis. The goals of this study are: (1) to research patient demographics, dental and skeletal relationships and treatment variables; (2) to test for temporal trends in these patients and their treatment across a 26 year interval from 1980 to 2005; and (3) to assess the correlations among patient demographics, dental and skeletal …
Use Of Cvm Stages In Assessment Of Young Orthodontic Patients To Estimate Growth Potential, David Justin Sander
Use Of Cvm Stages In Assessment Of Young Orthodontic Patients To Estimate Growth Potential, David Justin Sander
Theses and Dissertations (ETD)
Harnessing a patient’s growth to correct parasagittal discrepancies is an important part of Class II correction in orthodontic treatment; however, orthodontists rarely have the opportunity to choose when a patient is referred to them. Diagnostic records can assist the orthodontist in determining how much growth a patient has remaining. The purpose of this retrospective cephalometric study was to determine whether the amounts of in-treatment facial growth differ significantly by sex and by cervical vertebral maturation (CVM) stage. The sample consisted of 133 Class II division 1 patients from a single private practice office treated with a combination of a functional …
Cephalometric Evaluation Of Bionator Therapy In The Early Treatment Of Class Ii Malocclusions, Daniel C. Sawrie
Cephalometric Evaluation Of Bionator Therapy In The Early Treatment Of Class Ii Malocclusions, Daniel C. Sawrie
Theses and Dissertations (ETD)
Early or two-phase orthodontic treatment of Class II malocclusions is a debated topic in orthodontic circles primarily because the benefits of early intervention have not been consistently reproduced among researchers. The present study was a retrospective analysis of cephalograms from patients with Class II, division 1 malocclusions at the start of treatment. These were 50 consecutively treated youths who received phase 1 (early) treatment with a Bionator appliance and later treatment with full appliances (all treated by a single clinician). The comparison group consisted subjects treated in a single phase with fixed Edgewise appliances only. Importantly, subjects in the two …
Cephalometric Evaluation Of One-Phase And Two-Phase Treatment Alternatives In Matched Class Ii Subjects, Fredrick Jerome Burr
Cephalometric Evaluation Of One-Phase And Two-Phase Treatment Alternatives In Matched Class Ii Subjects, Fredrick Jerome Burr
Theses and Dissertations (ETD)
“Early” or two-phase orthodontic treatment of Class II malocclusions is a highly debated topic in the orthodontic literature. We report here on a retrospective cephalometric study of patients with Class II, division 1 malocclusions. One group consisted of 32 consecutively treated patients who received “early” treatment with a Fränkel II appliance followed by treatment with full fixed appliance. These subjects were “matched” by sex and cephalometric value, to a subject treated with standard edgewise appliances in a single phase. Matching criteria focused on the bony facial characteristics, notably ANB, NAP, Y Axis, AOBO, FMA, overjet, and overbite. The question was …
Quantitative Analysis Of First- Versus Second-Premolar Extraction Effects In Orthodontic Treatment, Robert A. Turner
Quantitative Analysis Of First- Versus Second-Premolar Extraction Effects In Orthodontic Treatment, Robert A. Turner
Theses and Dissertations (ETD)
Malocclusions can involve arch-size tooth-size discrepancies that have to be resolved by premolar extractions. Treatment planning in such cases usually involves removing first (P1) or second premolars (P2). Choosing an extraction pattern is a learned skill that incorporates many diagnostic factors. This study compared the amounts of in-treatment tooth movement in two common extraction patterns (4/4 and 5/5) in order to gain insight into the criteria used for differential diagnosis and treatment planning. Objective: A method of cast analysis was developed to measure the anteroposterior and transverse changes in tooth positions during orthodontic treatment. Data were used (1) to …
