All surgery will be in upper arch, for sandwich osteotomy technique, after local anesthesia, crestal incision with buccal intrasulcular incisions will be done extending at least one tooth mesial and distal to the implant associated site. Full thickness mucoperiosteal flaps will be reflected to allow access for implant, distraction osteogenesis, xenograft. Osteotomy for implant will be carried out with advanced kit of roott\_system Switzerland brand, sandwich osteotomy technique will be carried out with three full thickness cuts using the tungsten carbide disc were performed in the form of two vertical cuts away from the neighboring teeth by 3 mm and one horizontal bony cut on the labial surface of alveolar ridge. Bone splitting chisels were used in sequential width (2 mm, 3 mm) and lightweight mallet to complete splitting of the bony segment, the surgical sites will be irrigated with sterile saline. Surgical flaps will be sutured to the pre-surgical level.

All surgery will be in upper arch, for sandwich osteotomy technique, after local anesthesia, crestal incision with buccal intrasulcular incisions will be done extending at least one tooth mesial and distal to the implant associated site. Full thickness mucoperiosteal flaps will be reflected to allow access for implant, distraction osteogenesis, xenograft with and with RGD. Injectable RGD-bioconjugate Mussel Adhesive Proteins (RGD-MAPs) composite hydroxypropyl methylcellulose (HPMC) hydrogels . Previously we developed a novel type of injectable self-supported hydrogel (2 mg/ml of RGD-MAPs/HPMC) based porcine nano hydroxyapatite (MPH) for dental graft, which could good handling property, biodegradation or biocompatibility with the hydrogel disassembly and provided efficient cell adhesion activity and no inflammatory responses. Surgical flaps will be sutured to the pre-surgical level with 4-0 polyproline non resorbable suture utilizing a single interrupted suturing technique.
