Horizontal Ridge Reconstruction of Atrophic Anterior Maxillary Ridges Using Customized Xenograft Bone Shell With 1 :1 Mixture of Autogenous and Xenograft Bone Particulate

Brief Summary

Detailed 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 .
