Vaseline Saves Dentists from Tough Situations

For me, removing resin cement after cementing ceramic onlays to the abutments has always been a challenge, especially ceramic onlays milled in-office. After cementation, overflowed resin cement can get all over the tooth surfaces. Once hardened, removing the resin cement is often a big ordeal. Sometimes it seems like there is no way to separate the onlay from the neighboring teeth immediately, as if they are unintentionally splinted.  

Vaseline can save a lot of hard work if it is applied lightly on the proximal contact surfaces of the neighboring teeth before cementation.  

The onlay preparation is done, and the CEREC onlay is milled. The proximal contact of the onlay is adjusted by using a Black Diamond Strip, The Ideal Proximal Contact Adjuster, and tooth #3 is ready for the cementation of the onlay.

Vaseline is applied on one side of the ContacEZ White Serrated Strip, The Gentle Saw, Interproximal Cement Cleaner

The Vaseline on the White Serrated Strip is rubbed and transferred onto the proximal surface of the neighboring tooth. It is necessary to be careful to ensure the Vaseline does not contaminate the abutment.

Resin cement is loaded on the abutment.

After the resin cement has hardened, the excess is removed instrumentally.

A Gold Subgingival Strip is used to trim off the excess resin cement remaining in the subgingival area, and it is then polished with the Copper Subgingival Strip.

The Gray Final Polishing Strip is used to polish the proximal surface of the onlay to a natural texture.
