Design outcomes

Primary

Measure	Time frame
The primary endpoint is the precision of implant position in gypsum models (conventional impression) compared to milled and printed digital models manufactured from intraoral scanning.The precision is measured with the STL data from each group by superimposing (STL=STereoLithography).	—

Secondary

Measure	Time frame
The secondary outcome is the clinical quality (assessed by modified USPHS criteria) (USPHS=US Public Health Service)	—
