case_images: Allen's mild Type C, between maxillary right canine and maxillary left central incisor [Figure 1]. After thorough evaluation of the history, clinical condition, and radiological investigations, surgical correction of the defect area by VIP-CT graft, harvested from the palate, in combination with alloplastic (hydroxyapatite and beta tricalcium phosphate) bone graft was planned since hydroxyl appetite is a slow-resorbing alloplastic bone graft material; it will help in maintaining the volume of defect fill.

case_images: Following a presurgical rinse with chlorhexidine and administration of local anesthesia (2% lidocaine with 1:100,000 epinephrine), a labial full-thickness flap was elevated by giving crestal incision extending from maxillary right canine to maxillary left central incisor followed by two vertical releasing incisions, and the ridge defect was exposed [Figure 2a]. A VIP-CT pedicled graft was harvested from the palate [Figure 2b].

case_images: After thorough debridement of the bony defect and removal of all the granulation tissue present, alloplastic bone graft (Sybograft-plus [Eucare Pharmaceuticals(p) Limited, Chennai, India]) (hydroxyapatite and beta tricalcium phosphate) was condensed into the defect using a graft carrier, thus increasing the width in the buccal palatal aspect [Figure 4a]. The VIP-CT graft which was harvested at the beginning of the procedure was then placed and sutured [Figure 4b] over the bone graft, to increase the width as well as the apicocoronal height of the ridge. The flap was sutured back with 3-0 silk suture [Figure 4c].
