Resumo
This study aimed to evaluate the clinical results of bone cement graft technique in patients who
underwent the treatment of gummy smile regarding to gingival and alveolar mucosa health, smile
characteristics and possible correlations with subnasal depression maxilla (DSM) and the thickness
of the graft. Fifteen patients, feminine gender, 38,6 (+-11,2) years old, and 63,1 (+-23,5) months
after surgery, were provinient from a private dental clinic, which were collected initial photographs
of the maximum spontaneous smile previous to surgery. Clinical examination was performed to
evaluate probing depth (PS), bleeding on probing (SS) and obtain final photographs of the
maximum spontaneous smile after surgery. The initial and final photographs were submitted to
metric analysis using ImageJ software to measure gingival display (EG), crown length (CC),
vermilion length of the upper lip (CVLS) and change the position of the upper lip (APLS). The
graft thickness (EE) and the DSM depth were measured through cephalometric analysis in lateral
radiograph image after surgery. Paired t test was used to compare EG, CC and initial and final
CVLS, and Pearson correlation test was used to correlate: initial EG with the depth of DSM;
change (final - initial) of EG and CVLS and the APLS with EE. All statistical tests were performed
at a significance level of 5%. Changes in alveolar mucosa and gingival health were not verified (PS
= 2.3 + - 0.5 mm; SS = 13.1 + - 9.8%). There were statistical significant differences between initial
EG (4.5 + - 1.6 mm) and final (2.5 + - 1.4 mm) (p = 0.001), initial CC (8.9 + - 1.0 mm) and final (
9.4 + - 0.9 mm) (p = 0.003). CVLS initial (5.0 + - 1.2 mm) and final (5.5 + - 1.2 mm) showed no
significant differences (p = 0.07). Significant correlation was observed only for changing the
CVLS (11.5 + - 21.8%) with the EE in percentage (87.9 + - 16.7%) (r = 0.79; p = 0.01). It can be
concluded that the bone cement grafting, regardless of its thickness, promoted a reduction of
44.9% gingival display. Of this, 32.6% was attributed to APLS without changes in gingival health
and alveolar mucosa after a median follow-up period of 5 years and 3 months.
