A Gummy smile is characterised by excessive gingival display and is considered an unaesthetic aspect of an individual's smile. The presence of dentoalveolar complexities, such as a significantly rotated premolar, further impacts smile quality. A 33-year-old female presented with a chief complaint of a gummy smile and a 180°-rotated maxillary first premolar. Dentoalveolar diagnosis confirmed proclined upper and lower incisors reflective of an anterior deep bite, which is a causative factor of gummy smile. The patient was provided with surgical and non-surgical treatment alternatives for both clinical challenges. However, the patient preferred non-surgical orthodontic treatment. A biomechanically designed sequential treatment plan was devised, which involved derotation of the premolar using couple mechanics and alignment and levelling of both arches. This was followed by the TAD system, using four temporary skeletal anchorages with controlled intrusion to achieve the desired aesthetic outcome. Once derotation and realignment were achieved, vacuum-formed retainers were prescribed for consistent post-treatment use. A non-surgical, orthodontic treatment involving derotation and intrusion of the dental arch was proven successful. This sequential treatment plan, aligned with biomechanical principles, also reduced the likelihood of tooth tipping, highlighting its effectiveness.Keywords: Gummy Smile, Dental Arch, Temporary Anchorage Devices, Intrusion, Rotation, Dental Esthetics
