ABSTRACT

BACKGROUND:

A new open“C”-shaped molar band with nanocoating (patent numberZL201110057699.1) has been invented to overcome some weakness of traditional bands and buccal tubes, which is used for molar fixation.

OBJECTIVE:

Using three-dimension finite element analysis software to theoretical y prove that the new band comes up to clinic requirement.

METHODS:

We established a finite element model of alveolar bone-tooth-band, and node domains tensile and shear loading were given. Stress distribution of the new bands through numerical simulation was predicted and calculated. Simulation of 20 N orthodontic force was applied in medial direction, distal direction and vertical direction in the three-dimensional model of a new band buccal tube and traditional band, to analyze the stress state in different directions under the force of the binder. RESULTS AND

CONCLUSION:

By numerical simulation of three-dimensional finite element, the stress of the new band was higher than that of the traditional band, but it could not reach the clinical cracking limit of resin reinforced glass ionomer cement. So the new band could theoretical y satisfy the clinical requirements.
