Each patient will receive four implants placed in a quadrilateral configuration (lateral incisor and first premolar regions) under a stereolithographically manufactured surgical guide. Following 3-4 months of osseointegration, definitive mandibular overdentures will be fabricated and retained exclusively with Equator® attachment systems (Rhein 83, Bologna, Italy). Patients will be followed for 3 years to assess implant survival, peri-implant soft tissue health, and marginal bone changes.",[14],{"name":15,"affiliation":5,"role":16},"Mohammed El-Sawy, PhD","PRINCIPAL_INVESTIGATOR",[18,23],{"name":19,"role":20,"phone":21,"phoneExt":7,"email":22},"Mohammed A.
