Neoss Closed Tray Impressions

Neoss Closed Tray Impressions


In this video, we will demonstrate the use
of the Neoss closed tray impression technique. In a closed tray technique, the impression
coping remains in the patient’s mouth when the impression is removed. The Neoss closed tray impression coping is
available in three different lengths, and is packaged in a kit consisting of the coping,
screw, a plastic extension sleeve, a red cap, and replica. A unique feature of the all Neoss impression
copings is that they are ‘self-seating’. This means that the screw will not engage
the implant if the coping is not correctly seated. However, a radiograph is recommended if there
is any uncertainty or risk of soft tissue entrapment. First, the plastic extension sleeve on the
impression coping screw is removed. The implant connection is exposed and we make
sure that the top of the implant is clear of any soft or hard tissue. Place the desired length impression coping
onto the implant and tighten the screw with the screwdriver and manual handle. The upper part of the impression coping has
a direction indicator located between the two flat surfaces that will enable the red
plastic cap to orientate bucco-lingually. The red plastic cap is then gently pushed
and rotated to engage the flat sides of the impression coping and correctly seated. We recommend using a medium to heavy body
impression material, inject around the impression coping and fill the impression tray. When the impression material has set, remove
the impression (the red plastic impression cap is ‘picked up’ in the impression). Using the screwdriver, unscrew and remove
the implant-level impression coping from the patient. We now screw the implant replica onto the
impression coping, and utilising the two flat surfaces, we reposition the impression coping
into the correct position within the red plastic cap. One prosthetic platform for Ø.35-6.0 implants;
allowing for a minimal number of components. The kit contains all you need including an
option for Open Tray technique. ‘Self-seating’ coping – engages the
implant only if correctly seated.
