Ultimate Zirconia Coping Design: Understnding Aesthetics and Function

eLABORATE Magazine featured Yugo’s article titled ‘Ultimate Zirconia Coping Design: Understanding Aesthetics and Function’ in Sep/Oct 2012 (published language: English).   Introduction: It has been a decade since Zirconia became available to the dental market, and it is now one of the premier alternatives to Porcelain Fused to Metal (PFM) restorations.   There are always pros and cons in selecting any material, and dental professionals need to treat their chosen material properly to ensure the longevity of the restorations.

Custom abutments are necessary to control the emergence profile, as well as the Sub-Gingival Contour (SGC). Customised Zirconia...

eLABORATE Magazine featured Yugo’s article titled ‘Reproducing Nature Part 2: Blending into natural dentition’ in May/June 2006 (published language: English).     Introduction:   Isn’t colour matching a restoration to nature one of the hardest things for all of us to achieve?

The teeth in the mouth are always under the influence of the colour from the gum, and it is very easy for human eyes to make misjudgements...
