   inspire!
    Clinical Efficiency…Dependable Debonding
    inspire!™ is the only crystal clear bracket available in ortho-
    dontics. It goes on clear and stays clear throughout treatment.
    Improved heat treatment ensures reliability by maintaining the
    strength of the material, making it highly resistant to fractures.

    Modifications of the tie-wing geometry of inspire! make the
    wings more available for ligation and produce more robust
    wing strength, which significantly reduces the potential for
    wing failure. Greater under-tie-wing space accepts double
    ligatures without increasing the overall dimensions of the
    bracket. Improved tumbling has resulted in better rounding
    of corners and edges, which fosters greater patient comfort
    and minimizes wire binding.
                                                                         Debonding inspire! is simple. Just squeeze the mesial and dis-

 fewer appointments. We should never
 compromise the quality of the clinical
