The use of a flowable ormocer for bonding brackets

PURPOSE: To evaluate the effectiveness of the ormocer Admira Flow for bonding brackets. METHODS: 45 extracted human premolars were used. They were divided into two groups: (1) Brackets cemented with the traditional resin orthodontic bonding system Transbond XT, and (2) Brackets bonded with Admira Flow. Shear bond strength was measured with a universal testing machine with a cross-head speed of 1 mm/minute. The adhesive remnant on the tooth after debonding was quantified using image analysis equipment. RESULTS: No significant differences were observed in bond strength for Transbond XT and that of Admira Flow, nor were there significant differences in the quantity of adhesive remnant left on the teeth after debonding (P < 0.05).
