Extreme Masking: Achieving Predictable Outcomes in Challenging Situations with Lithium Disilicate Bonded Restorations

The International Journal of Esthetic Dentistry featured Yugo’s article titled 'Extreme Masking: Achieving Predictable Outcomes in Challenging Situations with Lithium Disilicate Restorations' in 2014 (originally published in English, German, Italian, Spanish and Greek).   Aesthetically speaking, metal-free restorations are proven to be superior alternatives to traditional porcelain-fused-to-metal (PFM) restorations. However, one of the most significant challenges in metal-free dentistry is the reproduction of natural dentition without the influence of a ‘negative stump’ – i.e., a very dark or metalcore showing through the final restorations.   This article presents a unique ‘outside of the box’ technique that provides consistent, predictable and durable restorations, which provide the best possible aesthetic outcome.   If you ask me to nominate the milestone in my career, this is undoubtedly one of them...

CORRECTION OF MIDLINE CANT WITH A SINGLE CENTRAL INCISOR

The primary objective of treating a single central incisor is to create a restoration that blends in with the surroundings. The two front teeth - upper central incisors -are the most dominant part of the smile, and they are used to determine the position and cant of a facial and dental midline. Studies suggest that the most important relationship to evaluate the aesthetics is the mediolateral inclination of the maxillary incisors. If the incisors are inclined by 2mm right or left, laypeople regard this as unesthetic.   Figs 1 & 2 show a trauma case with damaged right upper central incisor – 11. The assessment of the facial midline can only determine with a full-face photo; however, the images suggest enough to indicate...
