Cementation:

Metallic cementation:

 

1. With metallic cementation Zink-phosphate based cements are recommended because of the lack of shrinkage that occurs in the drying process

2. a combination of the shrinkage that occurs in the drying process of resin based cements and the thermal expansion that occurs with metallic copings allows for excessive cement space. This excessive space is the main cause of adhesive failure.

3. all cements weather resin, resin glass-ionomers, or Zink phosphate based, will work with metallic copings. Be aware, you may see a larger number of metallic coping adhesion failures when using resin based cements
