AUSTRALASIAN DENTIST 99 LABS small details are crucial in achieving a bond that is both strong and durable. The integration of Biomic LiSi Connect into bonding protocols not only addresses the challenges of zirconia’s inert surface but also enhances the material’s potential for use in high-aesthetic cases. By creating a robust interface between the veneer and the tooth, this innovative agent allows zirconia’s full range of benefits to be realised. The result is a restoration that meets the highest standards of clinical performance and patient satisfaction. Considerations in preparation Zirconia’s inherent strength enables it to be used effectively in situations where minimal reduction is preferable to reduce patient discomfort and maintain the integrity of the tooth. However, the preparation process for zirconia veneers plays a pivotal role in their overall success. Proper preparation not only supports the longevity and functionality of zirconia veneers but also enhances their seamless integration with the natural dentition, providing a restoration that looks and feels exceptional. Minimal tooth reduction is typically recommended, with reductions typically ranging from 0.3 to 0.5 mm. This conservative approach helps dentists to preserve the natural tooth structure while providing sufficient space for the veneer. Additionally, smooth, rounded transitions are essential to avoid sharp angles that could interfere with the fit or weaken the restoration. Another critical aspect of zirconia veneer preparation involves masking dark preps before taking impressions. Dark areas in the underlying tooth can create shadows or uneven tones in the final restoration, which may compromise the aesthetic result. Using a masking agent helps block these dark areas, and allows zirconia veneers to achieve a consistent, natural colour, particularly in high-translucency cases where colour harmony is crucial. In the planning of the overall restoration, dentists must also consider factors such as occlusion, tooth alignment, and patient-specific needs to ensure the success of the veneers. Advanced tools and technologies play a role in improving precision and efficiency during zirconia veneer preparation too. Dentists can achieve smoother transitions and controlled tooth reduction with fine-grit diamond burs, which help preserve tooth structure and prevent weak points. Digital scanners create accurate impressions, and Cone-beam computed tomography (CBCT) provides detailed imaging of tooth structure and occlusion VISIT BOOTH #112 CEMENTATION. THE THERA WAY.

This holistic approach to preparation allows zirconia veneers to deliver results that are both aesthetically pleasing and functionally robust. Final thoughts Zirconia veneers represent a significant advancement in restorative dentistry, combining durability, strength, and aesthetic appeal. While their unique properties have historically posed challenges in bonding, innovations like Biomic LiSi Connect have transformed the landscape, enabling reliable and longlasting adhesion. By addressing these challenges, Biomic LiSi Connect enhances the performance of zirconia veneers, and allows dentists to confidently apply them in high-aesthetic and high-function cases. For patients, this translates to a resilient, beautiful smile that endures over time. As demand for durable and aesthetic restorations continues to grow, zirconia veneers stand out as a leading choice for advanced restorative dentistry. Their superior strength, translucency, and ability to integrate seamlessly into complex treatment plans make them an invaluable tool for achieving exceptional clinical outcomes. With proper bonding protocols and preparation techniques, zirconia veneers can meet the highest standards of aesthetics and functionality and support better patient outcomes. u About the author Ian Feigen is Technical Services Director at full-service dental lab, Avant Dental.
