Benefits of Lithium Disilicate
One of the main benefits of lithium disilicate crowns and fillings is its translucency: meaning it can better match your natural teeth. In fact, according to a 2019 review in BMC health, lithium disilicate is more esthetically translucent than conventional zirconia, which is another type of material used in restorative dentistry. So if you want a great way to maintain your smile’s radiance, lithium disilicate is an excellent option.
Also, if you’re getting a crown made of lithium disilicate, it’s a relatively quick process. In fact, you may be able to enter your dentist's office with a chipped front tooth and leave that same day with a restoration. Using more traditional methods, your dentist would have to send your dental impressions to a lab, and it would take a week or so to receive the final restoration. But with this new approach, your dental appliance is ready to be inserted in about an hour. That's because the crowns are fabricated in-house at the dental office with a CAD/CAM machine, which carves the crown or filling from a solid block of material.
Further, research has shown that, though lithium disilicate is relatively new to the market, the material is long-lasting and resistant. Studies have shown that a lithium disilicate's survival rate was 94.8% after eight years for tooth-supported crowns and 100% after five years for implant-supported crowns. Researchers have also reported lithium disilicate shows a low incidence of mechanical failures, like debonding, fractures, and chipping. So not only does this material make your dental appointments more convenient, but it also means you may need fewer appointments in the future to redo deformed fillings and crowns.
