Six-month bracket failure rate with a flowable composite: A split-mouth randomized controlled trial

Abstract

INTRODUCTION: The use of flowable composites as an orthodontic bonding adhesive merits great attention because of their adequate bond strength, ease of clinical handling and reduced number of steps in bonding. OBJECTIVE: The aim of this Randomized Controlled Trial was to comparatively evaluate over a 6-month period the bond failure rate of a flowable composite (Heliosit Orthodontic, Ivoclar Vivadent AG, Schaan) and a conventional orthodontic bonding adhesive (Transbond XT, 3M Unitek).METHODS: 53 consecutive patients (23 males and 30 females) who fulfilled the inclusion and exclusion criteria were included in the study. A total of 891 brackets were analyzed, where 444 brackets were bonded using Heliosit Orthodontic and 447 brackets were bonded using Transbond XT. The survival rates of brackets were estimated with the Kaplan-Meier analysis. Bracket survival distributions for bonding adhesives, tooth location and dental arch were compared with the log-rank test.RESULTS: The failure rates of the Transbond XT and the Heliosit Orthodontic groups were 8.1% and 6% respectively. No significant differences in the survival rates were observed between them (p= 0.242). There was no statistically significant difference in the bond failure rates when the clinical performance of the maxillary versus the mandibular arches and the anterior versus the posterior segments were compared.CONCLUSIONS: Both systems had clinically acceptable bond failure rates and are adequate for orthodontic bonding needs.

A Clinical Comparison of Failure Rates of Metallic and Ceramic Brackets: A Twelve-Month Study

“…is is attributed to higher masticatory forces in posterior region, problems with moisture control, poor access, bracket-tooth contact after bonding, and increased amount of prismatic enamel [37]. On the other hand, Krishnan et al [33] noted 1.7 times higher failure rate in the anterior region. Recent survey focused on the evaluation of patterns of bracket failure relates this to the increased activation forces exerted by an archwire in the crowded dental arches or increased mastication load [26].…”

A Comparison of Shear Bond Strength of two Visible Light Cured Orthodontic Adhesives -An In-vitro Study

“…Previously our team has done extensive research that ranged from epidemiological studies to randomised clinical trials that have been published in reputed journals. (Felicita, 2017a(Felicita, , 2017b(Felicita, , 2018Felicita, Thirumurthi and Jain, 2017;korath, Padmanabhan and Parameswaran, 2017;krishnan, Pandian and Rajagopal, 2017;Charles et al, 2018;Pandian, krishnan and kumar, 2018;Reddy et al, 2018;Chinnasamy et al, 2019) .we have also done clinical trials on bond strength (Samantha, 2017). We wanted to compare the shear bond strength of the new adhesive-Brace Paste with that Enlight -an orthodontic adhesive produced by Ormco and hence this study.…”

“…Our extensive research expertise ranged from epidemiological studies to randomized clinical trials that have been published in reputed journals (Felicita, 2017a(Felicita, , 2017b(Felicita, , 2018Felicita, Thirumurthi and Jain, 2017;Korath, Padmanabhan and Parameswaran, 2017;Krishnan, Pandian and rajagopal, 2017;Charles et al, 2018;Pandian, Krishnan and Kumar, 2018;reddy et al, 2018;Chinnasamy et al, 2019). This knowledge was instrumental for us to study the effectiveness and the efficiency between the conventional method and Suresmile technology.…”
