About

Using customized Xenograft bone shell with mixture of autogenous and xenograft particulate in modified cortical shell technique. by 3D printed model from The CT scans segmentation by special software

Full description

Using customized Xenograft bone shell by 3D printed model from The CT scans segmentation by special software ( Mimics ) . All surgeries were performed by the same surgeon .

All surgical procedures were performed under strict aseptic conditions, all patients received infiltration local anesthesia (Articaine 4% 1:100 000 epinephrine).

a midcrestal incision was made in the anterior region using No. 15 blade. A full thickness mucoperiosteal flap was raised to expose the underlying alveolar ridge. The residual remaining bone in the area was minimal, with a maximum measured ridge thickness of 3 or 4 mm. 'To reconstruct the lost alveolar bone, an xenograft bone shell approximately 1 to 2 mm thick was shaped, after 3D print the bone shell were fixed to the buccal defect, using screws . 'The space between the plate and the existing palatal bone wall was then filled using a combination of autograft bone chips and xenograft bone particles

. Periosteal releasing incision is done to obtain stress free primary closure. The flap will then be closed using interrupted 4/0 resorbable sutures. After 4 month will insert implant . After 3 month will insert final restoration which will be mostly PMF .
