[Esthetics restoration after rapid orthodontic extrusion of subgingivally fractured incisor: a case report] [English Abstract, Journal Article]
Hua Xi Kou Qiang Yi Xue Za Zhi 2007 Apr; 25(2):206-7.
A case of a patient with subgingivally fractured incisor was presented. Two weeks after root canal therapy, the subgingival fragment was restored with fiber post, resin core and temporary crown. Gingivoplasty was performed around. after the subgingival fragment had been elevated in the axial direction by means of edgewise fixed appliance. Stabilized and held for 6 months, the incisor was restored with all ceramic crown. Optimal esthetic was achieved when restoration was performed after rapid orthodontic extrusion which had lifted up the fracture line above the level of the gingival line within 14 days. At 6-month follow-up, the periodontal tissues were normal and neither luxation nor relapse was noted.
