Straumann® IMPRESSION COPINGS

Tissue level and tapered effect implant

Narrow neck implant (NN, 3.5mm platform) fixture level impressions can be carried out with a metal, silver colored direct impression coping and screw (catalog # 048.016) screwed to the implant or with a white nylon snap on impression coping (catalog # 048.1224), to be captured in the impression material. Regular neck (RN, 4.8mm platform) fixture level impressions can be conducted with traditional engaging metal, red colored impression coping and screw, direct impression copings (catalog # 048.090) or a two component plastic impression coping to be captured in the impression material. The two part snap on impression coping consists of a white nylon basket (catalog # 048.017) that snaps over the shoulder of the implant and a red plastic positioning cylinder (catalog # 048.070) that slides inside the nylon basket and engages the internal octagon of the implant. Wide neck implant (WN, 6.5mm platform) fixture level impressions can be executed with traditional engaging, metal direct impression copings (catalog # 048.091) and screws or a two component plastic impression coping to be captured in the impression material. The two part impression coping consists of a white nylon basket (catalog # 048.013) that snaps over the shoulder of the implant and a white plastic positioning cylinder (catalog # 048.095) that slides inside the nylon basket and engages the internal octagon of the implant.
Abutment level impression copings for RN implants are a two part set, consisting of a white nylon basket (catalog # 048.017) and a solid abutment height dependent color coded positioning cylinder. Positioning cylinder colors correspond to the installed solid abutment color. 4mm height abutments employ a yellow cylinder (catalog # 048.060), 5.5mm abutments require a gray cylinder (catalog # 048.061) and 7mm abutments utilize a blue cylinder (catalog # 048.062). A flat side inside the cylinders correlates to the flat side machined on to the solid abutment. The white nylon basket is slipped over the solid abutment, engaging the shoulder of the implant through the snap on feature and the positioning cylinder is pushed inside the basket over the abutment, lining up the flat side of the abutment with the flat side of the colored cylinder. Orientation of the flat side inside the cylinder is accomplished through a raised nub on top of the positioning cylinder. Wide neck implants (WN) solid abutments impressions follow the same technique as RN implants but a different color scheme. Positioning cylinders are color coded green (catalog # 048.065) (4.0mm solid abutment height) and brown (catalog # 048.066) (5.5mm solid abutment height). The WN white nylon impression basket catalog number is 048.013. Sets including the actual abutment, protective cap, impression coping basket, positioning cylinder, temporary coping, analog and burn out coping are available as a convenience package from Straumann®

Bone level implant

Traditional implant/abutment platform fixture level impressions can be accomplished with platform specific direct and indirect, engaging impression copings. The impression coping body's are not color coded, only the fixation screw and in case of indirect impression copings a plastic cap are color coded for identification. Narrow connection (NC, yellow) direct impression copings (catalog # 025.2202) consist of a metal coping body and a separate screw whereas the indirect impression coping (catalog # 025.2201) comprises a coping body, the fixation screw and a disposable yellow plastic cap. This plastic cap is supposed to be captured in the impression material and is meant to stay in the impression at all times after impression taking. Two flat sides inside the plastic cap engage corresponding flat sides on the indirect impression coping body and the cap is pressed on to the coping body after the impression coping body is securely fastened on to the implant with the fixation screw. A double arrow indented on top of the plastic cap indicates parallelism with the flat sides inside the plastic cap to ease proper orientation of the cap on to the impression coping bodies flat sides. Regular connection (RC) impression parts follow the same set up as NC components with the exception of the color coding identification. RC impression coping fixation screws and plastic caps are purple in color. The indirect RC impression coping catalog number is 025.4201 and the direct RC impression coping number is 025.4202.
Abutment level impressions are performed in a similar fashion as tissue level solid abutment impressions. Color coded plastic impression copings are snapped over already installed abutments intended for this simplified impression method. Plastic impression copings are color coded according the implant/abutment platform diameter, abutment height and emergence profile of the abutment. Eight different combinations are possible with this impression technique system. Blue (3.5mm emergence profile) and yellow (5mm emergence profile) components indicate the NC platform and gray (5mm emergence profile)and brown (6.5mm emergence profile)indicate the RC platform. A attached secondary black plastic piece on top of the plastic impression coping denotes a 4mm abutment height in compliance with a black band etched on to the actual abutment. A attached secondary white plastic piece on top of the plastic impression coping denotes a 5.5mm abutment height in compliance with a white band etched on to the actual abutment. Each impression coping is manufactured with four inside flat sides to be related to the flat sides of the actual abutment. At the time of impression the impression coping is snapped over the abutment, ensuring alignment of the inside flat sides with the four external flat sides of the abutment.
