Case 1: Post Core and Zirconia Crown on #24 - Part II

My first case went well with thorough supervision and guidance from Dr. Nol Rithy. I'm wholeheartedly grateful and appreciative of his guidance during the process. As I worked on the case, I learned more about prosthodontics and my interest in this subject heighten. It will be one of the most memorable first dental treatment cases in my career.

The gingival extension is over-contoured when it sent from Dental Lab. The over-contouring will put pressure on gum and consequently might lead to gingival recession. The 0.5 mm gingival extension was re-contour circumferentially to follow the natural convexity emergence profile, which follow the concavity of root surface at CEJ.
