Angle Orthod 1991; 61:133-44. Related Articles The Importance of Orthodontic Retainers Decades ago, orthodontists used to think that once teeth were moved into the “right” positions, they would stay there forever. Results suggest a need for empirical research on factors affecting the retention of economic concepts by students in the early primary grades. Statistically significant differences in cephalometric measurements were found between the minimally crowded group and the moderately to severely crowded group. evaluated the effectiveness of retention. The long-term response to mandibular anterior alignment was unpredictable; no variables, such as degree of initial crowding, age, sex, Angle classification, etc., were useful in establishing a prognosis. Diplomates of the American Board of Orthodontics routinely see patients 10 years, 20 years, even 30 years post treatment. The sample was regrouped according to the postretention degree of incisor irregularity. In addition, retention protocols, materials, and techniques are reviewed and analyzed in order to give expert guidance for the prescription of individualized retention. The problem of retention and stability in orthodontics is well over a century-old. and any complication or failure was recorded. Nov 21, 2019. The dental casts and cephalometric radiographs of 46 patients, treated with mandibular second premolar extraction and edgewise orthodontic mechanotherapy, were evaluated for changes over a minimum 10-year postretention period. 2: CHAPTER . employees. Results showed no difference in long-term stability between the two groups. Maintaining the treatment result following orthodontic treatment is one of the most difficult aspects of the entire treatment process. Retention is a culmination of all our orthodontic knowledge. All students experienced concept lessons and completed immediate and delayed posttests on their understanding of the concepts. Am J Orthod 1981; 80:349-65. evaluation of stability and relapse.

Research over the past thirty years has shown that this is not true — there is no “right” position that can assure a permanent, unchanging result. The differences between the mean relapses of the control and the CSF cases were highly significant at both time intervals. Twenty-two of the 30 cases (73%) demonstrated clinically unsatisfactory mandibular anterior alignment postretention. Retention is an integral part of orthodontic treatment. The aim of this article is to define stability, retention and relapse with reference to the literature and to review the evidence with regards to clinical effectiveness of different types of fixed and removable retainers and, Objective: Online Journal of BioSciences and Informatics, ---------------------------------------------------------------------------------------------------------------------, -------------------------------------------.

On a long-term basis, the CSF procedure was shown to be more successful in reducing relapse in the maxillary anterior segment than in the mandibular anterior segment. After 2 years all three retention methods were successful in retaining orthodontic treatment results. Latest Features. Unpublished paper 1974.
