Abstract

<p>This report is to present a case of a patient with a severe gummy smile who was successfully treated by orthodontic aligners and crown lengthening. The patient, a 26-year-old female, presented to our hospital with a chief complaint of gingival exposure in a high smile. The gingival exposure in a high smile was about 7 mm, and she had a pronounced overbite and altered passive eruption. The anterior teeth were tipped in an inclined position by orthodontic treatment. Relative intrusion by 2 mm was achieved, followed by absolute intrusion by 1mm in the axial direction. The patient's facial appearance was reevaluated, and orthodontic fine-tuning was performed again. After orthodontic treatment, the patient's facial appearance was reevaluated and the amount of gingival resection was determined based on CT scan images and dental models, and crown lengthening was performed. The gum exposure in a high smile, which was her chief complaint, was improved and satisfactory results were obtained. </p>
