Regeneration of a 2 to 3 wall defect caused by a cemental tear.
1) Clinical preoperative view of the affected area showing the lesion. 2) DIAGNOSIS: Cemental tear – likely caused by a parafunctional habit overlapped to partial edentulism and malocclusion in the area.
3) After reflection of a mucoperiosteal flap the periodontal defect is de-granulated and the fractured portion of the cementum is visible. 4) The root surface is thoroughly scaled and planed.
5) The defect is filled with a mixture of autogenous bone and Geistlich Bio-Oss®. 6) A trimmed Geistlich Bio-Gide® collagen membrane is positioned on the augmented area.
7) 4 months after periodontal regenerative surgery a probing depth of 3 mm and a clinical attachment loss of 6 mm was measured distally. 8) Intraoral radiographic aspect of the site showing the healing of the defect.
