As there isn't metal in the infrastructure, a dark line is not seen at crown-gingiva level. It creates a more aesthetic view. Upon gingival recession, full porcelains remain aesthetic, metal porcelains create a bad view at the point of integration with teeth. The porcelains without metal backing have an advantage. It is not risky for people allergic to some metals (like nickel etc.) contained in the infrastructure.
Standard total partial dentures are implemented with or without implant backing integrated with latest technology in our clinic.
