Abstract
A Comparison of the Failure Rate of Two Orthodontic Light-Curable Adhesives: A Chart Review
Ian Montgomery Weaver, D.D.S.
Background and Objectives: The overhead costs of running a private orthodontic practice are infamously high, thus there is a notable benefit to finding the most cost effective methods of treating patients while still maintaining high quality care. A relatively new light-cure orthodontic adhesive BracePaste®® (American Orthodontics™, Sheboygan, WI), introduced to the market in 2017, can fluoresce under UV light to assist in identifying the difference between the enamel of the tooth and the adhesive material itself, an ability which can aid in the prevention of unnecessary enamel loss during the debond process. In addition to the potential changes this new feature may introduce, the price of BracePaste®® is below that of other commercially available bracket adhesive systems such as Transbond XT™ (3M™ Company, St. Paul, MN) which is often used as a gold standard to compare other adhesive systems. Comparing Transbond XT™ to BracePaste® and finding favorable results may provide evidence of an effective alternative to the highly regarded gold standard in the orthodontic bonding space. To this end, this study seeks to evaluate BracePaste® against Transbond XT™ by assessing the bonding failure rate amongst populations of patients whose brackets were bonded with either or both bonding adhesives to assess their performance in a clinical setting.
Materials and Methods: Patient information was gathered from AXIUM patient management software from a selection of the patients treated at the West Virginia University graduate orthodontics clinic. The variables of: biological sex, the oral hygiene status, patient age at start of treatment, Angle’s molar classification, the manufacturer of the brackets used in the patient’s treatment, the bracket adhesive system recorded by tooth number, and the number of days between the initial bonding of the teeth until the day the patient reported a debond incident were recorded and analyzed using Kaplan-Meier statistical analysis.
Results: The failure rate of BracePaste® was 17.5%. The failure rate of Transbond XT™ was 15.3%. These rates were not found to be statistically significant. No statistically significant difference was found for any of the variables aside from patient hygiene. Patients with fair hygiene were found to have the highest survival rate with a failure rate of only 10.2% and patients with poor hygiene were found to have the lowest survival rate at a failure rate of 28.3%.
Conclusions: There is no significant difference in the in vivo failure rates of brackets bonded with either Transbond XT™ and BracePaste®. There is no significant difference between the failure rates of brackets dependent on the quadrant bonded in, patient sex, or Angle’s classification. Patient’s oral hygiene does have a significant effect on the failure rate of brackets bonded to their teeth.
