DESSLoc® abutments can be used in old restorations without any problems. In addition to the already known advantages of the traditional components, DESS has added some improvements that make DESSLoc® the better solution for such restorations.
These improvements come mainly from the exclusive coating* of Zirconia Nitride (ZrN), a fully biocompatible material which increases the hardness of the abutment surface.
Additionally it decreases the coefficient of friction in comparison to the traditionally used Titanium Nitride and vastly out-performs some of the low-quality alternatives that have no coating or are simply anodized.
Thanks to the ZrN surface treatment a reduction of inflammation as well as a decrease in plaque formation is observed. Due to these increased performances the DESSLoc abutment has an improved functional life in comparison to other solutions. Furthermore, the color of the coating increases the aesthetic quality of the prosthetic restorations.
With regards to the usability of the DESSLoc® solution, there is also a manual plastic transporter included with each abutment at no additional cost. This is of a great help for the first stage of manual placement, especially on posteriors where space can be minimal and access difficult. The DESSLoc® system also features a new insertion key with anti-dropping feature for torque wrenches.
All in all a wonderful answer for removable full prosthetic restorations!
