“…This practitioner treated patients who had higher initial PAR scores (largely due to more crowding) with self-ligating brackets, which could have contributed to the greater increase in arch length in the self-ligating group. Scott et al [2008] observed no difference in arch length between the self-ligating and conventional bracket systems even though the initial incisor irregularity was higher for the conventional bracket group.…”

“…For 80% power, a clinically significant mean difference was hypothesized and standard deviation estimated for treatment duration (Harradine 2001), intercanine width (Germane et al, 1991;, and mandibular incisor proclination (Scott et al, 2008) to achieve the required sample size (Tables 1a-c). Since all these variables were considered of equal importance to the study, it was determined that a sample size of 47 patients in each group were needed.…”

“…Though, some studies have shown a greater increase in intermolar width with self-ligating brackets [Jiang and Fu, 2008;Scott et al, 2008;Pandis et al, 2010], their meta-analysis did not find any significant differences in the intercanine and intermolar widths between the two bracket systems [Chen et al, 2010]. For incisor proclination, a meta-analysis indicated that selfligating brackets resulted in slightly less mandibular incisor proclination (1.5 degrees) [Chen et al, 2010].…”

“…However, a large retrospective study [Hamilton et al, 2008] and all prospective studies have found no measurable advantages in orthodontic treatment time, the number of treatment visits, and time spent in initial alignment with self-ligating brackets over conventional brackets [Miles, 2005;Miles et al, 2006;Pandis et al, 2007;Scott et al, 2008;DiBiase et al, 2011, Johannson et al, 2012. Recent meta-analyses included only three retrospective studies due to significant methodological differences and found no difference in terms of reduced overall treatment time, number of visits, and efficiency of initial orthodontic alignment between selfligating brackets and conventional brackets.…”

A Retrospective Investigation of the Effects and Efficiency of Self-ligating and Conventional BracketsMegha AnandChairperson of the Supervisory Committee: Greg J. Huang Department of Orthodontics Introduction: Marketing strategies for self-ligating brackets have focused on less need for extractions and faster treatment. Recent meta-analyses have not found these claims to be well supported, but they point out limitations of the current evidence. These meta-analyses also conclude that additional, well-designed studies are indicated to improve our evidence base. The purpose of this retrospective cohort study is to assess the effects and efficiency of treatment with self-ligating brackets compared to conventional brackets. A secondary purpose is to identify any pretreatment malocclusion characteristics associated with choice of either self-ligating or conventional brackets. Methods: Patients treated in the private offices of two practitioners who simultaneously used both self-ligating and conventional brackets were selected for this study. The self-ligating subjects were selected first, and for each subject, an age and gender matched subject was chosen from the respective office. The self-ligation subjects were consecutively treated adolescents and young adults (11-25 years-old) who completed comprehensive fixed appliance therapy between January 1, 2011 and April 31, 2012. Patients with craniofacial anomalies, surgical treatment, treatment with arch expansion using expanders, interdisciplinary treatment, and incomplete records were excluded. The outcome measures were changes in the intercanine width, intermolar width, and arch length for both arches, change in mandibular incisor inclination, final PAR score, percent PAR reduction, overall treatment time, total number of visits, number of emergencies, number of broken brackets, and other emergencies such as a wire sliding to one side or the loss of ligation. All measurements were performed on digital models or digital lateral cephalograms in a blinded manner. PAR scores were measured by two calibrated assessors and the average of the two scores were used. Data were analyzed using the independent sample t-test, chi-square or fisher exact test and linear regression analysis. Results: The final sample comprised 74 patients from Clinician 1, and 34 patients from Clinician 2. The two clinicians exhibited significant differences in treatment duration, as well as in treatment strategies, such as the use of the SureSmile technique. Therefore, the decision was made not to pool the data from the two offices. For Clinician 1, no significant differences were observed between self-ligating and conventional brackets for the outcomes described above, other than increased arch length in both arches in the self-ligating group. The self-ligation patients treated by Clinician 2 demonstrated a significant increase in transverse dimension, less percent reduction in PAR score, less treatment time, fewer visits, and more wire sliding emergencies compared to the conventional bracke...

“…47,48 It is possible that as treatment progresses, the use of vibratory force may influence levels of OIIRR experienced, particularly during the subsequent phase with a 0.019 x 0.025-inch stainless steel archwire. However, evidence of OIIRR early in treatment is correlated with final levels of OIIRR after treatment completion.…”

INTRODUCTION A multicenter parallel 3-arm randomized clinical trial was carried out in 1 university and 2 district hospitals in the United Kingdom to investigate the effect of supplemental vibrational force on orthodontically induced inflammatory root resorption (OIIRR) during the alignment phase of fixed appliance therapy. METHODS Eighty-one subjects less than 20 years old with mandibular incisor irregularity undergoing extraction-based fixed-appliance treatment were randomly allocated to supplementary (20 minutes a day) use of an intraoral vibrational device (AcceleDent; OrthoAccel Technologies, Houston, Tex) (n = 29), an identical nonfunctional (sham) device (n = 25), or fixed appliances only (n = 27). OIIRR was measured blindly from long-cone periapical radiographs of the maxillary right central incisor taken at the start of treatment and the end of alignment when a 0.019 × 0.025-in stainless steel archwire was placed (mean follow-up, 201.6 days; 95% confidence interval [CI], 188.6-214.6 days). Data were analyzed blindly on a per-protocol basis because losses to follow-up were minimal, with descriptive statistics, 1-way analysis of variance, and univariable and multivariable regression modeling. RESULTS Nine patients were excluded from the analysis; they were evenly distributed across the groups. Mean overall OIIRR measured among the 72 patients was 1.08 mm (95% CI, 0.89-1.27 mm). Multivariable regression indicated no significant difference in OIIRR for the AcceleDent (difference, 0.22 mm; 95% CI, -0.14-0.72; P = 0.184) and AcceleDent sham groups (difference, 0.29 mm; 95% CI, -0.15-0.99; P = 0.147) compared with the fixed-appliance-only group, after accounting for patient sex, age, malocclusion, extraction pattern, alignment time, maximum pain experienced, history of dentoalveolar trauma, and initial root length of the maxillary right central incisor. No other side-effects were recorded apart from pain and OIIRR. CONCLUSIONS The use of supplemental vibrational force during the alignment phase of fixed appliance orthodontic treatment does not affect OIIRR associated with the maxillary central incisor. REGISTRATION ClinicalTrials.gov (NCT02314975). PROTOCOL The protocol was not published before trial commencement. FUNDING Functional and sham AcceleDent units were donated by the manufacturer; there was no contribution to the conduct or the writing of this study.
