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 )

implant stability
Implant stability will be measured by ISQ using an Ostell device
Time frame: 6 months
plaque index
plaque index will be measured with periodontal probe according to the following score 0; absence plaque , score 1; plaque only detected by a probe passing through the smooth marginal surface of the implant, score 2; plaque can be recognized by naked eye, and score 3; plenty of soft matter.
Time frame: one year
gingival index
gingival index and bleeding will be measured using periodontal probe according to the following score ; 0; no bleeding when a periodontal probe is passed along the mucosal margin, 1;isolated bleeding spots visible, 2; blood forms a confluent red line on the mucosal margin, 3;heavy or profuse bleeding
Time frame: one year
Pocket Depth
Pocket Depth around implant will be measured by mm using periodontal probe
Time frame: one year
