Long-Term Evaluation of Clinical Performance of Directbonded Brackets: An Epidemiologic Survey

Abstract

Aim:The objective of the current epidemiologic study was to investigate characteristics associated with bracket failure in bonded brackets. Materials and methods:A retrospective study on data of 144 patients treated during 2009 to 2012 was done. Baseline data including age, gender, malocclusion, bite type and debonding incidences per teeth were retrieved. ANOVA analysis and t-test were used to evaluate the data.

The association between patient’s compliance and age with the bonding failure of orthodontic brackets: a cross-sectional study

“…The aforementioned results could justify the fact that adult patients presented a lower breakage rate (12.3%) than adolescents (25.4%) (Table 4 ). These values agree with several studies that observed that the incidence of failure of brackets seems to decrease with age and that the level of cooperation of adults is higher, counterbalancing even the greatest mechanical difficulties in their tooth movements [ 1 , 13 , 16 , 17 , 25 , 27 , 28 ].…”

“…Patient motivation represents an important factor for orthodontic treatment success, and it is directly associated with patient cooperation regarding care and hygiene instructions provided by the orthodontist. A high level of motivation may decrease brackets failure, a common problem observed in the orthodontic practice that may causes great treatment delays [ 2 , 10 , 13 , 15 – 17 ]. Robb et al (1998) [ 15 ] reported that treatment duration changes up to 46% are related to bracket failure.…”

“…When assessing distribution per arch (Table 1 ), we found a higher bracket failure rate in the lower arch (9.5%), and this result agrees with previous studies [ 1 , 5 , 9 , 19 , 20 ]. The challenge in maintaining the lower arch dry during bracket bonding, the higher initial crowding, and the occlusal interference may be the causes of greater failure [ 1 , 17 , 20 ].…”

“…In the literature, we found failure rates between 2.5% and 16.1%in studies using the direct bonding technique (Atashi & Shahamfar, 2013;Li , et al, 2016;Jung, 2014;Roelofs, 2017;Linklater & Gordon, 2003). The relatively low percentage of failures observed in this study (3.3%) might be related to the instructions given to patients after bracket bonding.…”

“…(1998 ) have found that these failures have a direct influence on the efficacy of treatment and variation in treatment duration. In another study, Atashi & Shahamfar (2013) observed that the number of failures tended to be higher among young patients, thus emphasizing the importance of encouraging treatment compliance in these patients.…”
