Comparison Between Two Placement Concepts of Six Compressive

Comparison Between Two Placement Concepts of Six Compressive Implants in the Maxillary Edentulous Ridge and Immediately Loaded With a Full Arch Prosthesis: A Study of Implant Stability and Peri-implant Tissue Health

The aim of this study will be to compare two posterior implant positioning concepts of six compressive implants installed in completely edentulous maxilla and immediately loaded with screw retained prosthesis regarding implant stability and peri-implant tissue health (plaque index ,bleeding index and pocket depth )

Inclusion Criteria:

• healthy Patients with completely edentulous maxilla opposing a dentate mandible or a mandible restored with a full arch fixed prosthesis will be selected for this study from the outpatient clinic, Prosthodontic Department, Faculty of Dentistry, Mansoura University.

Exclusion Criteria:
