“…Of these, 20 were graded as moderate value of evidence (grade B) and served as a basis for the conclusions, 3,4,71,[78][79][80][81][82][83][84][85][86][87][88][89][90][91][92][93][94] 18 were graded as low value of evidence (grade C) (Table 5), and none were graded as a high value of evidence (grade A).…”

“…Long-term morphologic stability after treatment of crowding was studied in 12 studies: eight studies 3,[78][79][80][81][82][83][84] were graded B (Table 6), whereas four 12,96,108,109 were graded C. All eight studies graded B were retrospective, and seven used control or reference groups. One study was a cohort study.…”

“…One study was a cohort study. 83 The follow-up period varied between 7 and 20 years, and fixed or removable appliances had been used in all but one study. 82 Most of the studies focused on morphologic changes in the lower jaw, particularly the position of the mandibular incisors.…”

Objective: To evaluate morphologic stability and patient satisfaction at least 5 years after orthodontic treatment. Materials and Methods: Published literature was searched through the PubMed and Cochrane Library electronic databases from 1966 to January 2005. The search was performed by an information specialist at the Swedish Council on Technology Assessment in Health Care. The inclusion criteria consisted of a follow-up period of at least 5 years postretention; randomized clinical trials, prospective or retrospective clinical controlled studies, and cohort studies; and orthodontic treatment including fixed or removable appliances, selective grinding, or extractions. Two reviewers extracted the data independently and also assessed the quality of the studies. Results:The search strategy resulted in 1004 abstracts or full-text articles, of which 38 met the inclusion criteria. Treatment of crowding resulted in successful dental alignment. However, the mandibular arch length and width gradually decreased, and crowding of the lower anterior teeth reoccurred postretention. This condition was unpredictable at the individual level (limited evidence). Treatment of Angle Class II division 1 malocclusion with Herbst appliance normalized the occlusion. Relapse occurred but could not be predicted at the individual level (limited evidence). The scientific evidence was insufficient for conclusions on treatment of cross-bite, Angle Class III, open bite, and various other malocclusions as well as on patient satisfaction in a long-term perspective. Conclusions: This review has exposed the difficulties in drawing meaningful evidence-based conclusions often because of the inherent problems of retrospective and uncontrolled study design.

Objective: To compare the long-term outcome 9 years after removal of two different types of fixed retainers used for stabilization of the mandibular anterior segment. Materials and Methods: Sixty-four children who had undergone orthodontic treatment with fixed appliances in both arches were divided into two groups depending on which kind of retainer being used. Twenty-eight of the patients had a canine-to-canine retainer bonded to the canines and 36 had a bonded twistflex retainer 3-3, bonded to each tooth. Measurements were made on study models and lateral head radiographs, before and after treatment, 6 years after treatment, and 12 years after treatment, with a mean of 9.2 years after removal of the retainers. Results: No significant differences were found between the two groups at the long-term follow-up according to Little's Irregularity Index or available space for the mandibular incisors. The overjet and overbite were reduced after treatment in both groups and stayed stable throughout the observation period. Also, no differences in bonding failures between the two retainers were found. Conclusions: Both a canine-to-canine retainer bonded only to the canines and a twistflex retainer 3-3 bonded to each tooth can be recommended. However, neither of the retention types prevented long-term changes of mandibular incisor irregularity or available space for the mandibular incisors after removal of the retainers.

Introducción: El propósito de esta revisión sistemática fue evaluar la efectividad de la fibrotomía supracrestal circunferencial como procedimiento coadyuvante en la estabilidad del tratamiento ortodóntico. Métodos:Se realizó una búsqueda electrónica en diferentes bases de datos. Los criterios de inclusión fueron: artículos entre el año 1980-2013, realizados en humanos, estudios que evaluaran la efectividad del procedimiento en un período no menor a 1 año y pacientes que no hubieran sido sometidos a tratamientos periodontales similares.Resultados: Un total de 268 títulos fueron encontrados en bases de datos electrónicas y en la búsqueda manual no se encontraron artículos relacionados con el tema. Un total de 37 abstracts fueron revisados y de éstos se exclu- AbstractIntroduction: The purpose of this systematic review was to evaluate the effectiveness of circumferential supracrestal fiberotomy as an adjunctive procedure in the stability of orthodontic treatment.
