A new approach using the surgical extrusion procedure as an alternative for the reestablishment of biologic width.
A modification of the surgical extrusion technique to treat fractured teeth was realized as an alternative periodontal therapy to avoid ostectomy following orthodontic extrusion of teeth with their biologic widths compromised by different etiologic involvements. After delicate luxation and arrested avulsion, the teeth were coronally positioned to allow room for a new biologic width. Clinical and radiographic monitoring showed the ability of the periodontium to adapt function and esthetic recovery. The advantages and disadvantages of this therapeutic procedure for resolution of a periodontal involvement are presented.
