Frequency of Bonded Bracket Failure in Patients, Undergoing Fixed Orthodontic Treatment

Abstract

OBJECTIVE: The objective of our study is to determine frequency of bracket bond failure in relation to age, gender, most commonly involved tooth and quadrant. METHODOLOGY: In this descriptive cross-sectional study, a total of 100 patients with ages ranging from 10 to 30 years needing corrective orthodontic treatment were selected for the study. This survey was conducted at Altamash Institute of Dental Medicine, Karachi. The survey was initiated on 30th November 2019 and was concluded on 30th May 2020. A questionnaire was used to evaluate the frequency of bonded bracket failure in patients undergoing orthodontic treatment. The bonded metallic brackets were light cured for 40 seconds, and initial alignment arch wires were inserted. Bonded bracket failure was recorded over a period of six months. RESULTS: The initial debonding results of the present study demonstrated a high number of debonded brackets in mandibular dentition as compared to the maxillary dentition. Whereas, when the teeth were debonded for the second time, a greater number of maxillary teeth were found to be affected by the debonding of the brackets. Both genders demonstrated a greater rate of bracket debonding in the second premolar area and lowest in the molar area. In our study, age and gender had no significant relationship with bracket bond failure and teeth involved in debonding. CONCLUSIONS: The frequency of bonded bracket detachment during orthodontic treatment is very common. Our study concluded that females were more affected by the bracket bond failure as compared to the males along with the second premolar being the most commonly associated tooth during an active orthodontic treatment.

Bracket Bond Failures: Incidence and Association with Different Risk Factors—A Retrospective Study

“…In this study, younger patients demonstrated a statistically significant higher bracket failure rate than older patients, which is in agreement with Jung et al study [20]. In contrast, Khan et al and Sakrani et al studies showed no significant difference in bond failure with patients' age [8,21]. Of the bracket failures, 58.4% occurred in younger patients (≤20 years).…”

“…Debonding of brackets in this study was more commonly found in the mandibular dental arch (p < 0.01). Such results correspond to the previous studies carried out by other researchers [8,12,[21][22][23]. These higher failure rates were attributed to occlusal interferences because brackets on lower teeth can be affected by upper teeth cups during mastication, especially in case of increased overbite.…”

“…Numerous studies have been done to sort out different factors associated with bracket failure during orthodontic treatment. Most of these studies evaluated the influence of age, gender, tooth type, type of brackets and bonding material on bond failure [4,[8][9][10]12,13,[20][21][22][23][24]. In some studies, the impact of malocclusion in terms of Angle class [4,8] and overbite [8,9] on bond failures was evaluated.…”

“…However, the connection between the overjet, detailly evaluated anterior teeth crowding and bond failure has not been clarified. Most of these studies were limited by a small sample size [10,13,[22][23][24] or short patient observation time (6-12 months) [8,10,13,[21][22][23][24].…”
