COMPARING CLOSED TRAY IMPLANT IMPRESSION TECHNIQUES USING SNAP ON AND IMPRESSION ANALOGUES ON A CLINICAL RADIOGRAPHIC SCALE

Several impression techniques have been proposed to achieve passive fitness between the prosthesis and the osseointegrated implant. The aim of this study was to compare closed tray implant impression techniques using snap-on and impression analogues on a clinical radiographic scale. The current study was comparative, descriptive, and retrospective, performed in a university setting in 2020. The data of patients reporting to the Department of Implantology between June 2019 to March 2020 were collected from patient records, and the data of 1000 plus patients were analyzed for snap-on impressions and impression analogue accuracy in seating and associated jig trial seating. A comparison of closed tray implant impression techniques using snap-on and impression analogues on a clinical radiographic scale found both to be perfect. The impression recorded with snappy with abutment and the impression recorded using impression coping exhibited no differences during jig trial seating verification. This study showed that both impression procedures are accurate and can be used for implant impressions.
