Implant placement was planned prosthetically using three-dimensional imaging and digital planning software. Stackable surgical guides were used to facilitate guided bone reduction when indicated and fully guided implant placement.\n\nSix implants were placed in the maxillary arch under local anesthesia following a standardized surgical protocol. Implants achieving adequate primary stability were immediately restored with a screw-retained provisional fixed prosthesis supported by multi-unit abutments. Patients were followed according to a predefined clinical and radiographic protocol for outcome assessment.",[13],"Stackable guided implant surgery",[15],{"name":16,"affiliation":5,"role":17},"Mohammed El-Sawy, PhD","PRINCIPAL_INVESTIGATOR",[19,23],{"name":16,"role":20,"phone":21,"phoneExt":7,"email":22},"CONTACT","00201061314522","Dr_sawy@windowslive.com",{"name":24,"role":20,"phone":25,"phoneExt":7,"email":26},"Mohammed T.
