”STEP BY STEP APPROACH IN TREATMENT OF GUMMY SMILE ”
Prof. Dr. Muhamed Ajanović
Faculty of Dentistry of Sarajevo University, Sarajevo, Bosnia and Herzegovina
A smile is an important non verbal method of communication and is an interaction between
the teeth, the lip framework and gingival scaffold. The smile-line is determined by the shape
and size of the lips, the facial muscles, shape and size of the teeth, and the gingival tissue.
Gingival tissue present in the smile-line should exhibit balance with the contours in harmony
with the upper lip. A medium smile line with minimal gingival display is considered a to be
most esthetic. Gummy smile (excessive gingival display) is a condition in which a high lipline exposes an abnormal amount of gingival tissue.
Several intra oral and extra
oral etiologies could contribute to a gummy smile. The muscle controlling the movement of
the upper lip could be hyperactive, resulting in an upper lip that rises higher than normal.
When this occurs, more of the gingival tissue is exposed when smiling. Other factors can
include, but are not limited to, delayed passive eruption and factors related to the dento
gingival complex. Gummy smile is commonly present and mostly have a negative affect on
the aesthetics of a smile. It is very important to be aware of modern and predictable treatment
options. This lecture will serve to explain and demonstrate: a new classifications with
appropriate management based on the etiology; the complete crown lengthening surgery,
including incision design, flap management and instrumentation, the innovative and
minimally invasive LipStaT procedure to correct a high and gummy smile in patients with
vertical maxillary excess, short and hypermobile upper lip.
