Spontaneous Resolution of Mandibular Incisor Gingival Recession Following Orthodontic Torque Correction With Fixed...

Gingival recession associated with excessive vestibular torque of mandibular incisors represents a significant periodontal challenge. This case report presents a non-surgical management strategy for an isolated deep recession in an adolescent patient. A 12-year-old female patient presented with severe mandibular anterior crowding and a 3 mm isolated labial gingival recession on tooth 31 (Cairo RT1/Miller Class I), secondary to severe vestibular root displacement. Treatment was carried out using a full fixed appliance (0.022-inch slot, Roth prescription) over 24 months. Individualized lingual root torque couples were progressively incorporated into 0.019 × 0.025-inch stainless steel (SS) finishing wires to relocate the root within the alveolar housing, strictly avoiding any mucogingival surgery. Significant spontaneous coronal migration of the gingival margin was achieved, reducing the recession from 3 mm to 1 mm, without root resorption. In adolescent patients presenting with RT1 recessions secondary to crown-vestibular malposition, early non-surgical orthodontic torque correction can result in significant tissue recovery and should be considered a reliable first-line therapeutic approach.
