Nobel Temporary Snap Abutment
Alex Rugh, CDT, explains the Temporary Snap Abutment from Nobel Biocare™.
The interface on the temporary snap abutment has retention fingers that allow it to snap into the implant or replica without a screw. This saves time from not having to repeatedly insert and remove the screw during try-in. Margin height options on these abutments create more flexibility for implants of varying depths and the shortened abutment heights reduce the need to grind down the abutments to meet vertical space requirements.
Today I want to talk about a newer product from Nobel Biocare™ called the Temporary Snap Abutment which is for the conical connection implants.
There are a few differences between this new snap abutment and a traditional temporary abutment.
The first and main difference is the retention mechanism that has been built in to the interface of the abutment. These retention fingers stick out slightly from the rest of the interface and snap in to place when the abutment is seated on to the implant or replica.
The advantage of this is that the abutment does not need to be screwed down while trying in and adjusting the temporary crown. This saves time from not having to repeatedly insert and remove the screw during try-in.
The second difference is that these abutments are offered with two margin heights, 1.5mm and 3mm. The original temporary abutments were only available with a 1mm margin and since the margin area is where the diameter of the abutment is at its largest, the 1mm height was not always ideal in deep implant sites.
The third difference is that the overall height of the abutments has been shortened which reduces or eliminates the need to grind down the height of the abutment. The wide platform abutments have the shortest height as they are most commonly used in molar positions.
Additionally, these abutments can be used in conjunction with the apical drill and drill guide analog. The drill guide analog has an internal channel that guides the apical drill through the analog and abutment to create a screw channel in the restoration without damaging the abutment.
