The metal ceramic crown is one of the most popular restorations used in dentistry today, because it combines the esthetics of porcelain with the strength of a metal substructure. However, one of the limitations of this restoration is the presence of a cervical metal collar. If this metal collar is placed at the gingival crest or slightly supragingivally, it may create an unaesthetic restoration. If this type of margin is placed periodontal tissues. In an effort to circumvent these potential problems and yet maintain the superior strength of the metal substructure, the porcelain labial margin metal ceramic restoration was developed. Various fabrication techniques for the porcelain labial margin have been described in the literature.
