DESIGINING CROWN CONTOUR IN FIXED PROSTHODONTICS: A NEGLECTED ARENA.

Yashpal Singh, Monika Saini

Clinical longevity of any prosthesis is directly related in achieving proper coronal contours. This involves close attention to detail between periodontal and prosthodontic principles during the fabrication of the prosthesis. If not done properly, iatrogenic problems may occur such as "food traps" from open contacts, overhangs, or plunging cusps. This leads to plaque accumulation, inflammation, bleeding, potential bone loss (periodontitis) thus leading to severe periodontal problems. If certain principles of placement of gingival margins and interproximal embrasures are not closely adhered to, an overcontoured restoration may act as a nidus in the rapid failure of the prosthesis.
