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 )

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
implant stability	Implant stability will be measured by ISQ using an Ostell device	6 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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.	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	one year
Pocket Depth	Pocket Depth around implant will be measured by mm using periodontal probe	one year
