What cement do you use to cement your implant crowns with?

Although I sometimes use a more permanent cement, usually I use tempbond, a temporary cement that is radio-opaque. Residual excess cement can be irritating when left around an implant restoration. It can even cause an infection if left undisturbed for a number of years. Originally I started using temporary cements because I thought it would make it easier to remove an implant crown in the event that an implant abutment became loose, but even temporarily cemented implant crowns can be difficult to remove safely using GC forceps (pliers used to remove crowns). I still use it routinely because it has other advantages.

Radio-opaque temporary cement is a good choice since caries (tooth decay) is never an issue for implant restorations and excess cement can often be visualized a post-op radiograph. More importantly, it is necessary to remove all excess cement after cementing any implant crowns, and tempbond is fairly easy to remove and actually tends to be water soluble.

If an implant crown is well fitting temporary cement usually holds the crown well for many years. If a crown does come out, it can be recemented.
