Design outcomes

Primary

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

Secondary

Measure	Time frame	Description
plaque index	one year	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.
gingival index	one year	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
Pocket Depth	one year	Pocket Depth around implant will be measured by mm using periodontal probe
