Innovative and Precise Solutions in Gummy Smile Management: The Impact of Digital Technology on Smile Regeneration

A gummy smile is a condition, in which the gingival tissue is excessively displayed when smiling. Orthodontic treatment is often combined with other treatments such as crown lengthening and composite restorations to treat the gummy smile. Crown lengthening may be executed utilizing a three-dimensional (3D) printed surgical guide, which provides precise digital measurement of the patient’s optimal gingival height and facilitates enhanced predictability in esthetic treatment results. This case reported postorthodontic treatment combined with a 3D-printed crown lengthening guide design to enhance the smile line and follow up with a composite restoration on lateral incisors. Patient exhibits a Class II skeletal malocclusion with gummy smile. The ultimate results of orthodontic treatment, as well as crown lengthening and composite restoration, are assessed through the use of a digital wax-up intraoral mock-up in 3D printing. Crown lengthening with a surgical guide offered precise results on a reference basis. The treatment was subsequently concluded with the placement of composite restorations on the lateral incisors. An examination of the complete smile showed 6.24 mm preoperative gingival display and 0.24 mm postoperative. Following 14 days, 1 month, and 3 months, the gingival appearance was steady. The patient expressed satisfaction with the final results of the interdisciplinary orthodontic treatment, which addressed their concerns while achieving the desired aesthetic outcomes. The utilization of 3D-printed technology helps to forecast treatment outcomes, which improves patient care in modern dentistry.
