Comparison in Shear Bond Strength of Orthodontic Brackets between Biofix and Conventional Bonding Systems: An in vitro Study

In vitro evaluation of shear bond strength of orthodontic brackets bonded with different adhesives

“…Bond strength determines the amount of force delivered and also affects the treatment duration. [ 10 11 12 ] Shear bond strength depends on various factors including the adhesive properties of the bonding materials, the attachment at the different interphases such as the tooth to composite interphase and the composite to bracket interphase, as well as the polymerization of the composite bonding material. [ 11 ] Bonding procedure involves etching, primer solution, and adhesive application followed by composite application.…”

“…Different generations of adhesive were developed to improve the bond strength and to reduce the duration. [ 10 12 13 ] There is a search for methods to improve the bond strength in the presence of moisture using light cured or self-cured material and hydrophilic adhesives. A major drawback of the auto-cured adhesive system is the inability of the practitioner to manipulate the setting time of the composite resin.…”

“…compared shear bond strength of brackets bonded with three different adhesive systems (Biofix, Transbond XT and Unite) and they found superior bond strength with Biofix compared to others. [ 10 ] Nirupama et al . observed highest bond strength with Transbond XT compared to other tested groups.…”

Biofix as an Alternative Orthodontic Adhesive for Bonding Orthodontic Brackets

“…Biofix was claimed to reduce chair time, cost effective and generate sufficient bond strength. [4] Consequently, the null hypothesis investigated in this study is that the Biofix has less strength while bonding orthodontic brackets and negative effect of enamel decalcification. Therefore, the aim of the study is to answer the question that: could Biofix be an effective orthodontic adhesive?…”

“…[1] Since the introduction of direct bonding orthodontics, bonding the brackets with various orthodontic adhesives to the tooth enamel has been a vital issue [2]. Consequently, numerous dental researches aim to investigate different bonding agents which can be used [3,4].…”
