This is a two part study to measure and observe the efficacy of botulinum toxin A for the
treatment of gummy smiles.
Part A will randomly compare three different doses of botulinum toxin type A
(abobotulinumtoxin A) for the treatment of upper anterior gummy smile with larger gingival
exposure (> 4 mm).
Part B will assign one of two doses of botulinum toxin type A for participants with smaller
gingival exposure (< 4 mm).
Follow-up visits with photography will occur 4 and 12 weeks after their treatment. Subjects
currently living in the Chicago metropolitan area and meet inclusion/exclusion criteria will
be considered for enrollment.
This study is a pilot study designed to determine feasibility of this procedure.
