Implant & Abutment System Connections<br />
Certain ® Internal Connection<br />
The internal connection aspect of the implant and abutment are designed<br />
for ease of use and simplicity.<br />
• QuickSeat ® Connection: It Clicks! The Certain Implant and Abutment<br />
Systems feature the QuickSeat Connection. This unique connection<br />
produces an audible and tactile “click” that confirms placement of<br />
Impression Copings and Abutments.<br />
• Abutment fingers cause the “click” and also provide retention for the<br />
prosthetic components in the implant before the screw is placed. A screw<br />
is needed to fully seat the components when the restoration is being<br />
tried in or definitively placed.<br />
• The 6/12 hex inside the internal connection incorporates both a 6-point<br />
single and a 12-point double hex. The 6-point single hex has two<br />
functions: engaging the driver tip for mountless delivery during implant<br />
placement and providing anti-rotation for all straight abutments.<br />
The 12-point double hex provides 30º rotational positioning for preangled<br />
abutments.<br />
• Impression Copings: Pick-Up and Twist LockTransfer Copings are<br />
available in the Certain Internal Connection design, in three EP ®<br />
(Emergence Profile) diameters and a straight diameter to match the<br />
corresponding Healing Abutment. The Impression Copings also “click”<br />
when properly seated. These copings have a different finger design that<br />
engages 2mm internally into the implant, as compared to the abutment’s<br />
design that engages 4mm deep into the implant. This shorter engagement<br />
into the implant is important because it allows off-axis draw for implant<br />
impressions that are divergent.<br />

• Color-Coding: Certain Implants and all interfacing components are<br />
color-coded by restorative platform diameter for easy identification<br />
and selection.<br />
