Abstract
This case report addresses the treatment of excessive gingival display (EGD) in the
context of maxillary asymmetry, zenith irregularities, and occlusal plane inclination.
Digital planning was pivotal in formulating a precise treatment strategy by incorporating
facial photographs, digital models, and cone-beam computed tomography data. Parameters,
including occlusal plane inclination, teeth position, and lip-to-gingival margin relationships,
were considered to ensure treatment alignment with the patient's facial characteristics.
Notably, during the planning phase, it was evident that the conventional approach
using the cementoenamel junction as the apical limit for incisions would result in
asymmetry. Consequently, the gingival margin position was defined in accordance with
facial and lip features. The chosen treatment, flapless crown lengthening, was tailored
to the patient's thin phenotype and guided by measurements derived from digital planning.
Postsurgery, the patient experienced a swift and painless recovery. A harmonious smile
with a stable gingival margin position was achieved at the 1-year follow-up, seamlessly
complementing the patient's facial attributes. This case underscores the importance
of personalized EGD treatment and the value of digital planning in enhancing diagnostic
accuracy and precise treatment planning, ultimately facilitating optimal treatment
strategies.
