“…Most bracket failures in deep bite cases were noticed on lower premolars, so adding bite blocks in these cases can decrease the incidence of bond failure. There was no significant effect of skeletal relationship on bond failure rates which is in agreement with previous studies [33]. In terms of the association between wire and bracket failure, most failed brackets were reported on the (0.016 ″ NiTi) wire.…”

Failure of brackets is a common problem in orthodontics. This affects the treatment time, cost, and compliance of the patient. This study was conducted to estimate the bracket failure rate and the related factors for the long term. Methodology. This ambidirectional cohort study included 150 nonsyndromic orthodontic patients undergoing fixed appliance therapy for the last two years. The same patients were followed for 7 months. Different variables related to bracket failure were evaluated. The available data were analyzed descriptively, and the Kaplan-Meier estimate was used to measure the bracket survival rate from the date of bonding to failure. Results. A total of 180 bracket bond failures in the 150 included patients (52.2% males and 47.8% females) with a median age of 17 years (range 10-25 years). 69% of brackets failures were reported within the first 6 months after bonding. About 58.3% of bracket failure was noticed in adolescent patients before the age of 18 years. The majority of the cohort (81.1%) has good oral hygiene. The failure rate in patients with normal overbite was 41.1%, in decreased overbite cases was 15%, while in deep bite cases the failure rate was 43.9% with a statistically significant difference. Adults show less bracket failure (41.7%) than adolescent patients (58.3%). More bracket failure was noted in the lower arch (55%) than the upper arch (45%), and there were more bond failures posteriorly (61%) than on the anterior teeth (39%). Majority (41.1%) of the bracket failed on round NiTi wires. Conclusion. The bracket failure rate was 6.4%, with most bracket failure occurring in the first 6 months after bonding with individual difference. There was more incidence of bond failure in an increased overbite, adolescents, lower arch, posterior teeth, and lighter alignment wires.

“…Brackets' detachment is a widely investigated issue, with an extensive literature of in vitro and clinical studies [8,10,[12][13][14]23]. The aim of the present study was to test different pretreating agents to find eventual differences among the products in order to assess which could cause lower detachment rate.…”

“…Various clinical studies tried to estimate the failure rate of orthodontic brackets, comparing brackets of different materials [8], types of orthodontic bonding [23], adhesion procedures [46] and adhesive materials [7,17,47]. In addition, retrospective studies investigated the issue, trying to assess correlations between brackets' failure rate and multiple variables [11,12,48].…”

“…During orthodontic therapy, a common but unpleasant occurrence is the possibility of brackets' detachment, which can cause the lengthening of treatment time and give discomfort to the patient [7][8][9][10][11]. A reasonable clinical failure rate should be below 10%, Materials 2022, 15, 531 2 of 19 but effectively, it has been assessed to be in the range of 0.6-28% [12]. The reasons behind bonding failure lie in the design of the bracket's base, in the surfaces of bonding and in their treatment methods [13,14].…”

Effect of Enamel Pretreatment with Pastes Presenting Different Relative Dentin Abrasivity (RDA) Values on Orthodontic Bracket Bonding Efficacy of Microfilled Composite Resin: In Vitro Investigation and Randomized Clinical Trial

Bonding failure is a clinical issue frequently encountered in orthodontic practice. The aim of this study was to evaluate enamel pretreatment both in vitro and clinically using agents with different RDA values before brackets’ bonding, to assess if RDA can affect the Shear Bond Strength (SBS), Adhesive Remnant Index (ARI) and clinical failure rate of orthodontic brackets. For the in vitro study, 220 bovine teeth were pretreated with agents with different RDA values. Subsequently, brackets were bonded. For the clinical study, 20 patients underwent bonding of 20 brackets each with a split-mouth design. Low and high RDA toothpastes were used for enamel pretreatment. SBS, ARI and failures were recorded. Higher SBS values were found for teeth pretreated with lower RDA agents; conversely, lower SBS values were found for teeth pretreated with higher RDA agents (p < 0.05). For high ARI values, RDA increased too (p > 0.05). In the clinical study, a significantly lower failure rate was reported for teeth pretreated with low RDA toothpaste (2.5% in low RDA group, 7.0% in high RDA group; p < 0.05). No significant differences were assessed comparing the two dental arches and anterior and posterior sites. Enamel pretreatment with low RDA toothpastes could increase brackets’ survival rate. Further in vitro and clinical studies would be welcomed to confirm these findings.

“…Prevalence of debonded brackets was reported highest in patients treated with fixed appliances of age 14-16 years at lower buccal segment including both the sexes 9 . While some studies indicate bracket breakage to be more common in maxillary (36.5%) buccal region than in mandible (22.8%), the lower anterior segment had the lowest percentage of bracket breakage 10,11 . As orthodontic emergencies can be multifactorial, a study of orthodontic patients at tertiary care hospital of Peshawar is warranted, due to the different food habits and musculoskeletal patterns of the population as well as difference in protocols followed by different hospitals.…”

OBJECTIVES: To determine the frequency of emergencies in patients with fixed and removable orthodontic appliances at tertiary care dental hospital. METHODOLOGY: A questionnaire was designed for this descriptive cross-sectional study to be filled by the clinician (L3/L4 FCPS resident) at the end of addressing every orthodontic emergency. Sampling was done under consecutive non-probability protocols. Descriptive statistics were applied to determine the frequency of different orthodontic emergencies, and Pearson’s chi-square test was applied to determine association of emergencies with gender and etiology of emergency (patient related vs operator related). Data was analyzed on SPSS version 20. RESULTS: A total of 175 patients reported with orthodontic emergencies. The sample comprised 38.3% males and 61.7% females. Most frequent orthodontic emergency reported was deboned brackets in fixed appliances, while the most common emergency in removable appliances was traumatic PNAM. A statistically significant association (Pearson’s Chi Square=4.74, Cramer’s V=0.165, p=0.029) was seen for removable and fixed appliance emergencies with males and females. CONCLUSION: Most frequent fixed appliance orthodontic emergencies were deboned brackets while for removable appliance emergencies were trauma due to PNAM. Emergencies with removable appliances were mostly due to the operator related factors, while in fixed appliances patient related factors were dominating.
