“…On the other hand, more recent studies by Miles [9] and Fleming et al [10] found no improvement in the efficiency of the treatment, although Pandis et al [11] verified that slight crowding was eliminated more rapidly with a Damon2 system than with conventional brackets in the hands of one same operator [11]. In two recent studies, Chen et al [12] and Fleming PS and Johal A [13] carried out a systematic review aiming at verifying clinical evidence on the impact of self-ligating systems in orthodontic treatments. In the first study [11], the authors concluded that, despite the claims as to the clinical superiority of self-ligating brackets, and the fact that they seem to have significant advantages regarding chair time and incisor proclination (less than 1.5 degrees), no significant differences were found in the time of treatment and in occlusal characteristics between the two kinds of brackets.…”

Objective: To analyze and compare the efficiency of the correction of mandibular crowding between two types of bracket systems. Material and method:According to the results of the power analysis for sample size calculation, 19 Angle Class I patients were included in the study and randomly divided into two groups: GI (n=10, mean age 19.68years, min 13.86, max 28.78, self-ligating brackets), and GII (n= 9, mean age 20.98years, min11.13, max 29.85, conventional preadjusted brackets). To carry out this study, the sequence of wires used was similar for both groups. Dental casts were made available at the start of the treatment (T1), after 180 days of leveling and alignment (T2), and at the completion of leveling (mean, 600 days, T3). The degree of crowding was measured by means of Little's and Fleming's irregularity indexes, by using a Mitutoyo digital caliper. Student's t test and ANOVA were used to compare the efficiency of mandibular alignment between the two groups. Results:The results showed that in the initial alignment phase (after 180 days), no statistically significant difference was found between the groups. On the other hand, from phase T1 to T3, it was observed a statistically significant difference between the groups regarding the correction of mandibular crowding.

“…2 When compared with conventional brackets, several advantages of self-ligating brackets have been claimed, including faster ligation, reduced friction, and faster treatment time with reduced number of visits and less pain. [3][4][5][6] In laboratory setups, self-ligating brackets have demonstrated reduced friction compared with conventional brackets tied with modules. 7,8 In other studies, however, reduced frictional resistance with self-ligating brackets compared with conventional brackets was found only in combination with certain wires.…”

“…17,18 There is still controversy and limited knowledge regarding the evidence for reduced overall treatment time with self-ligating brackets, and the need for prospective randomized studies is obvious. [3][4][5] Recent prospective randomized studies have shown that selfligating brackets do not reduce overall treatment time, neither in terms of number of visits nor treatment outcome. 19,20 The need for further evaluation of the overall efficiency of self-ligating brackets in daily orthodontic clinical work is thus important.…”

Objective: To conduct a prospective and randomized study of the efficiency of orthodontic treatment with self-ligating edgewise brackets (SL; Time2 brand, American Orthodontics) and conventional edgewise twin brackets (CE; Gemini brand, 3M). Materials and Methods: One hundred consecutive patients were randomized to treatment with either SL or CE brackets. The participants were treated by one of three specialists in orthodontics and with continuous instructions alternately by five orthodontic assistants according to our normal treatment routine (ie, modified 0.0220 MBT preadjusted edgewise technique). The treatments were evaluated in terms of overall treatment time, number of visits, and treatment outcome using the Index of Complexity, Outcome and Need (ICON). The number of emergency appointments, number of archwires, overjet, relative space, and extractions at treatment start were noted. Results: After dropouts, the analyzed material consisted of 44 patients treated with SL (mean age 15.3 years, mean ICON 60.7, 70.4% female) and 46 patients treated with CE (mean age 15.0 years, mean ICON 56.5, 71.7% female). There were no statistically significant differences between the SL and CE groups in terms of mean treatment time in months (20.4 vs 18.2), mean number of visits (15.5 vs 14.1), mean ICON scores after treatment (13.2 vs 11.9), or mean ICON improvement grade (7.9 vs 9.1). Conclusion: Orthodontic treatment with SL brackets does not reduce treatment time or number of appointments and does not affect posttreatment ICON scores or ICON improvement grade compared with CE brackets.

“…: La photobiomodulation laser semble pouvoir atténuer la douleur initiale à court terme [15,27] [9,10,26] ont montré qu'il n'existe pas de données publiées probantes permettant d'affirmer que l'emploi des brackets autoligaturants réduit la douleur du patient, raccourcit la durée totale du traitement, procure un résultat plus stable ou meilleur sur les plans esthétique ou occlusal, ou diminue le recours aux avulsions dentaires. Quelle est votre opinion et quelles sont les conclusions de vos récentes études [13,59], consacrées à la comparaison entre brackets autoligaturants et brackets conventionnels ?…”
