10 Patients having horizontally deficient anterior maxillary areas will be recruited and a preoperative CBCT will be done. The plan is to graft the defective ridges with simultaneously placing dental implants using a PEEK shell that will be specifically designed, constructed and 3D printed to act as a surgical guide for osteotomy drilling and implant placement as well as housing both the implant and the sticky bone (using a mixture of autogenous bone harvested from the symphysis area and xenograft both mixed with plasmatic matrix); that will be added to augment the defective ridge; the PEEK shell will also act as a barrier membrane for Guided Bone Regeneration and will add more stability to the placed implants that will be fixed to the PEEK shell occlusally with a Ti - based abutment.

Primary stability will be measured using Ostell and an immediate postoperative CBCT will be done and superimposed on the preoperative CBCT and an accuracy of plan transfer will be measured to make sure the planning was followed accurately.

Then 6 months later, another CBCT will be done to check the bone gain and quality and a second surgery will be done to remove the PEEK shell and proceed with the conventional implant prosthetic phase.
