Researcher will introduce the trial to patients and provide full explanation of its aim and benefits in Arabic language. Patients will then be able to have an informed discussion with the researcher. Researcher will obtain written consent from patients willing to participate in the trial
This protocol and the template informed consent form will be reviewed by the Ethics Committee of Scientific Research -Faculty of Oral and Dental Medicine- Al-Azhar University.

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.

Effect of RGD on volumetric bone changes
Cone beam computed tomography with minimal field of view was taken immediately after surgery, immediately before loading (6 months) and 6 months after loading to evaluate volumetric changes.
Time frame: Preoperative Cone beam computed tomography (CBCT) with minimal field of view will be taken for (implant treatment plan), immediately after surgery, at time of loading and 6 months after loading.
