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 …

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 …
Craniofacial Changes Following Nonextraction Orthodontic Treatment: A Long-Term Cephalometric Analysis, James Austin Rahaim
Craniofacial Changes Following Nonextraction Orthodontic Treatment: A Long-Term Cephalometric Analysis, James Austin Rahaim
Theses and Dissertations (ETD)
Long-term posttreatment cephalometric changes from late adolescence into early adulthood were analyzed in this study. Lateral cephalometric radiographs from a sample of 30 Class II division 1 Caucasian females treated without extractions were evaluated at posttreatment (mean age = 15.9 years) and recall (mean age = 28.3 years). All of the subjects were treated in the private practice of a single, experienced practitioner. The cephalograms were examined to investigate changes in the cranial base, midface, maxilla, mandible, maxillomandibular relationships, dental relationships, and the soft tissue profile that occurred at an average of 12.4 years posttreatment. Descriptive and inferential statistics were …
