Straumann® IMPRESSION COPINGS
Tissue level and tapered effect implant
Fig. 1
Narrow neck
implant (NN, 3.5mm platform) fixture level impressions can be
carried out with a metal, silver colored direct impression coping (Fig.1 left, catalog # 048.016) and screw,
screwed to the implant or with a white nylon snap on impression
coping (Fig.2 left, 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 (Fig.1 middle, catalog # 048.090) and screw, direct impression
copings or a two component plastic impression coping to be
Fig. 2
captured in the impression material. The two part snap on impression coping
consists of a white nylon basket (Fig.4 left, catalog # 048.017) that snaps over the
shoulder of the implant and a red plastic positioning cylinder (Fig.2 middle, catalog #
048.070) that slides inside the nylon basket and engages the internal octagon of
the implant (Fig.3).
Wide neck implant (WN, 6.5mm platform) fixture level
impressions can be executed with traditional engaging, metal direct
impression copings (Fig.1 right, catalog # 048.091)
Fig. 3
and screw 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 (Fig.4 right, catalog # 048.013)
that snaps over the shoulder of the implant and a white plastic positioning
cylinder (Fig.2 right, 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 (Fig.4 left, catalog # 048.017) and a solid abutment height dependent
color coded positioning cylinder (Fig.5). 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)
Fig. 5
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 (Fig.6), 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 knob on top of the
positioning cylinder.
Fig. 6
Wide neck implant (WN) solid abutment impressions
follow the same technique as RN implants but a different color scheme.
Positioning cylinders (Fig.5) 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 (Fig.4 right). 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®

Digital impressions
are carried out with three component, screw retained
Scanbodys. The three components are a scan cylinder (similar to Fig.7, A),
fixation screw (similar to Fig.7, B) and scan cap (Fig.7, C). Healing
abutments are removed from the implant and the scan cylinder is installed on
to the implant, ensuring proper engagement and seating of the indexing
feature (octagon). Hand tighten the fixation screw and snap the scan cap on
to the cylinder. The scan cylinder is machined with two opposing inside
flat sides corresponding to two flat sides on the scan cap. Both flat sides
have to be aligned correctly while pressing the scan cap on to the scan
cylinder. Once the scanbody (similar to Fig.7, D) is installed and
completely assembled, the scan may comence.

Tissue level implant scanbodys are available for all three
implant/abutment platform diameters. Narrow neck Scanbodys (Fig.8, catalog
# 048.067) are marked with the letters "NN" and regular neck platform bodys
(Fig.8, catalog # 048.068) are marked with the letters "RN" while wide neck
Scanbodys (Fig.8, catalog # 048.069) are marked "WN". Both cylinder and
cap are machined with a circumferential score line to attach dental floss
to prevent aspiration of the components.

Traditional 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
(Fig.9, left, catalog # 025.2202) consist of a metal coping body and a separate screw whereas
the indirect impression coping (Fig.10, left, 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
Fig. 10
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) fixture level impressions
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 (Fig.10, right) and the
direct RC impression coping number is 025.4202 (Fig.9, right).
Fig. 11
Digital impressions
are carried out with three component, screw retained
Scanbodys. The three components are a scan cylinder (Fig.11, A), fixation
screw (Fig.11, B) and scan cap (Fig.11, C). Healing abutments are removed
from the implant and the scan cylinder is installed on to the implant,
ensuring proper engagement and seating of the indexing feature (quadrigon).
Hand tighten the fixation screw and snap the scan cap on to the cylinder.
The scan cylinder is machined with two opposing inside flat sides
corresponding to two flat sides on the scan cap. Both flat sides have to
be aligned correctly while pressing the scan cap on to the scan cylinder.
Once the scanbody (Fig.11, D) is installed and completely assembled, the
scan may comence.
Fig. 12
Bone level implant scanbodys are available for both implant/abutment
platform diameters. Narrow connection Scanbodys (Fig.12, left, catalog #
025.2900) are marked with the letters "NC" and regular connection platform
bodys (Fig.12, right, catalog # 025.4905) are marked with the letters "RN".
Both cylinder and cap are machined with a circumferential score line to
attach dental floss to prevent aspiration of the components.
Fig. 13
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 (Fig.13) and gray (5mm emergence profile) and brown (6.5mm emergence
profile) indicate the RC platform (Fig.14).
Fig. 14
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.
