Pre-surgery

<p>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.</p>

Surgery

<p>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.</p>

Outcome

<p>5) The defect is filled with a mixture of autogenous bone and Geistlich Bio-Oss<sup>®</sup>. 6) A trimmed Geistlich Bio-Gide<sup>®</sup> collagen membrane is positioned on the augmented area.</p>

Follow-up after at least 6 months

<p>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.</p>
