Pre-surgery


							<p>1) Exposure of the alveolar ridge and buccal bone. 2) Horizontal and vertical osteotomies of the distracted segment.</p>

Surgery


							<p>3) The upward lift of the transported segment, achieving a height gain of 7 mm. 4) Geistlich Bio-Oss<sup>®</sup> Block is trimmed in a dry state with a piezo surgical device to the required dimension and shaped to completely fit into the recipient site.</p>

Outcome


							<p>5) The coronally shifted segment is fixed with miniplates and miniscrews and thus immobilizes also the biomaterial block. 6) A resorbable bilayer collagen membrane Geistlich Bio-Gide<sup>®</sup> is used to cover the grafted area.</p>

Follow-up after at least 6 months
