“…In accordance with our findings, they stated that both groups showed buccal tipping of molars. Cattaneo et al 12 indicated that transversal expansion of the upper arch was achieved by buccal tipping in a Damon group, which is in parallel with our results.…”

Objective: To evaluate two different treatment systems with regard to incisor position, transverse dimension changes in maxillary arch, changes in maxillary molar inclinations, clinical periodontal parameters, and pain intensity in patients with a Class I malocclusion. Materials and Methods: Seventeen patients (with a mean age of 14.5 years) underwent orthodontic treatment with the Roth prescribed edgewise bracket systems after expanding the maxillary arch with a quad-helix appliance, and 16 patients (with a mean age of 14.8 years) underwent orthodontic treatment with the Damon 3MX bracket system. Each subject's lateral cephalometric and posteroanterior radiographs and dental casts were obtained at the beginning of the treatment and after debonding. In addition to these, the periodontal index and pain scores were taken. Results: Cephalometric data showed that in both treatment systems, overjet value decreased and maxillary and mandibular incisors proclined. Posteroanterior measurements demonstrated a greater increase in the maxillary molar inclination in the Damon group. Significant increase of maxillary intercanine, interpremolar, and intermolar widths was shown in both systems. Periodontal index and pain score changes between different observation periods were the same. Conclusions: The conventional and Damon systems were found similar with regard to the incisor position, transverse dimension changes in maxillary arch, clinical periodontal parameters, and pain intensity. The only significant difference was that the Damon system inclined the maxillary molars more buccally than the conventional group. (Angle Orthod. 2014;84:615-622.)

“…Previous studies have also found a greater increase in the mandibular intermolar width for the self-ligation group, although there were no differences in the intercanine width [Jiang and Fu, 2008;Pandis et al, 2010]. Two of these studies, however, used differing archwire sequences and archforms similar to our study [Jiang and Fu, 2008;Pandis et al, 2010] and Fleming et al self-ligating brackets and similar low friction systems, which leads us to believe that physiologic buccal expansion and alveolar bone generation is questionable [Franchi et al, 2006;Cattaneo et al, 2011].…”

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...

“…Similar forces applied at the bracket produce substantially more (9u-14u) tipping. 2,10,16 Most importantly, lateral tooth movements caused buccal cortical bone to form. Since the bone was initially 1.4 mm thick, and the teeth were moved 0.96 mm, final thickness should have been 0.44 mm.…”

Objective: To produce buccal translation and determine whether buccal bone forms on the cortical surfaces. Materials and Methods: Eleven patients requiring maxillary first premolar extractions participated in this prospective, randomized, split-mouth study. Pre-and posttreatment records included models, photographs, and small field of view CBCT images. One randomly chosen maxillary first premolar was moved buccally with 50 g of force applied approximately at the tooth's center of resistance. The other premolar served as the control. Forces were re-activated every 3 weeks for approximately 9 weeks, after which the teeth were held in place for 3 weeks. Pre-and posttreatment records were analyzed and superimposed to evaluate changes in the dental-alveolar complex. Results: There was significant (P , .05) movement of the experimental premolar with minimal buccal tipping (2.2u). Changes in maximum bone height were bimodal, with 6 patients showing 0.42 mm and 5 patients showing 8.3 mm of vertical bone loss. Buccal bone thickness 3 mm apical to the CEJ decreased 0.63 mm. Direct measurements and CBCT superimpositions showed that buccal bone over the roots grew 0.46 mm and 0.51 mm, respectively. Conclusions: It is possible to produce buccal bodily tooth movement with only limited amounts of tipping. Such movements are capable of producing buccal bone apposition, but there are potential limitations. (Angle Orthod. 2016;86:527-534.)
