Subperiosteal bone-bonding devices have been proposed for less invasive treatments in orthodontics. The device is osseointegrated onto a bone surface without fixation screws and is expected to rapidly attain a bone-bonding strength that successfully meets clinical performance. Hence, the device's optimum shape for rapid and strong bone bonding was examined in this study by finite element analys...

OBJECTIVE The objective of this study is to test the antimicrobial effect of zinc oxide when incorporated into an orthodontic bonding material and to check the effect of addition of zinc oxide on the shear bond strength of the bonding material. MATERIALS AND METHODS Zinc oxide was added to a resin modified light cure glass ionomer cement (GIC) (Fuji Ortho LC GC America, Alsip, Ill) to make mo...

S umm ary An epoxy resin formulation has been developed to bond orthodontic attachments to enamel sur­ faces. The disruptive force required to break the bond under experimental conditions was in excess of the forces exerted on the orthodontic attach­ ments during treatment. This formulation has been subjected to a limited number of clinical trials. These tend to substantiate the experimental fi...

It is quite evident that in the practice of orthodontics, much time could be saved and much tedious labor could be avoided if a method were available to attach a bracket directly to a tooth surface. The object of this investigation was to determine if this could be accomplished by using Eastman 910 [6], a cyano-acrylate, as a bonding agent. This material is a thin , colorless liquid with a low ...

Two hundred and forty Begg orthodontic brackets prewelded to a Dyna-Bond pad were bonded to bovine incisors using four orthodontic adhesives and four anterior restorative materials. Then samples of each material were tested after one day, three months, and six months immersion in lactic acid utilizing the Instron Universal Testing Instrument. The mean bond strength of each material at each time...

AIM The study was undertaken to measure the changes within the mesh pad associated with reconditioning process, measure the bond strength of new and reconditioned orthodontic brackets and correlate the changes in mesh strand diameter with changes in bond strength. MATERIAL AND METHODS 120 clinically normal premolar teeth extracted for orthodontic reasons, were divided equally for bonding with...

INTRODUCTION Treatment with fixed orthodontic appliances requires the application of adhesive systems to enable secure fastening of brackets and retainers to the surface of tooth enamel. The orthodontic bonding systems are similar in terms of chemical composition to dental filling materials, the chemical stability of which is not satisfactory. Particularly alarming is the release of bisphenol A...
