High translucent zirconia is manufactured to reduce the effects of impurities and structural defects. With zirconia restorations, structural defects or impurities can absorb light rather than allowing the light to pass through. Translucency is affected by the way the material allows light to pass through it. What Makes High Translucent Zirconia Better than Normal Zirconia? If the patient requires multiple types of restorations, then lithium disilicate may still be the most suitable material due to its predictable treatment outcome and uniform shading.Most practitioners still prefer the translucency and esthetics of lithium disilicate for anterior cases. But this is just one study, and, even though high translucent zirconia is an exceptional material, it isn’t suitable for veneers, inlays, or onlays. One recent in-vitro study, which assessed the optical properties of these more modern zirconia materials and compared them with lithium disilicate, discovered that they exhibited higher translucency than lithium disilicate. High translucent zirconia is still a very new material and hasn’t yet been extensively studied. Although lithium disilicate is suitable for three-unit anterior and posterior restorations, high translucent zirconia offers the clinician and the patient an alternative. However, the flexural strength of high translucent zirconia is considerably higher than that of lithium disilicate. Lithium disilicate is extremely popular, with good reason, as, in the hands of a skilled technician, the crowns can look amazing. The more translucent materials, like IPS and e.max, which contain glass, provide excellent esthetic results but have a lower strength compared with zirconia. Zirconia High Translucent product details ›Ĭomparing High Translucent Zirconia with Lithium Disilicate GlassĪll-ceramic materials have differing compositions, crystalline contents, and microstructures that influence strength and translucency. High translucent zirconia restorations are easy to fit and can be cemented using standard cementation materials and techniques. Margin visibility also contraindicates its use for inlays and onlays. It seems like it should be the perfect material for dental veneers, but, unfortunately, this isn’t the case because of the margin’s high visibility and the prep thinness. High translucent zirconia is a versatile material and can be utilized for single anterior and posterior restorations, for bridges up to three units, and for implant crowns. High translucent zirconia provides clinicians and patients with more consistent and more esthetically appealing treatment outcomes while retaining a vibrant and natural translucency. With significantly improved translucency, the technician can fabricate restorations that more closely replicate natural teeth. Now, the newest generation of materials can provide patients with even better treatment outcomes due to increased translucency, better wear characteristics, and strength. Until even a few years ago it was challenging to produce a zirconia restoration that accurately replicated the natural translucency and opalescence of real teeth. We now have a much better understanding of the characteristics and physical properties of zirconia, and that knowledge has led to more predictable long-term treatment outcomes. With the evolution of zirconia materials, zirconia-based restorations have been more frequently used. The development of pre-shaded zirconia and the introduction of newer materials helped to overcome some of zirconia’s earlier limitations. Although the higher crystalline content found in the original zirconia materials provides much better flexural strength, it also increases the opacity of the material, diminishing esthetics. When zirconia was first introduced, it gave clinicians a much stronger alternative. The earliest all-ceramic materials provided better treatment outcomes but lacked the strength required for bridges and posterior crowns. However, although still a popular option, the opacity of the PFM materials cannot always satisfy esthetic demands. For many years, clinicians used PFM crowns and bridges to provide patients with durable, long-lasting restorations that offered reasonable esthetics. This is partially due to greater interest in and awareness of cosmetic dentistry. Patient demand for dental restorations with a natural esthetic has increased considerably over the past few decades. ![]()
