Lava Zirconia Tooth Crown Excellent and Super Strength Easy Clean

► Resistance to Fracture and Chipping

The fracture and chipping of Lava restorations at 1, 4, and 8 years of service are shown in Figure 2. Of the recalled restorations, 29 were replaced because they received a rating of 1 or 2 out of 5. In many cases the fractures resulted in the delamination of a large portion of the veneering ceramic, and the restorations could not be polished or repaired. Forty-eight restorations received a rating of 3 or 4. These were chipped restorations that either did not need any smoothing or polishing or could be polished and smoothed satisfactorily. In many cases the patient was not aware that the restoration had chipped.

The causes of the fractures could be the thickness of unsupported porcelain or possibly too rapid heating or cooling of the veneering ceramic. Rapid cooling of the restoration can result in the buildup of undesirable stresses within the restoration. None of the fractures involved a zirconia substructure or coping failure. They all involved the veneering ceramic.


The vast majority of Lava restorations received a 5 or excellent rating for esthetics. Only 46, or 4.8%, of 963 restorations received a rating less than 5. Lava restorations have definitely superior esthetics when compared to PFM restorations, especially because the Lava coping can be shaded to closely simulate dentin, eliminating the graying caused by a metal substructure. Once the patient experiences the esthetics of a Lava zirconia based restoration, they are elated with the outcome.

​► Resistance to Marginal Discoloration

Over 98% of Lava restorations received an excellent rating for resistance to marginal discoloration. Advantages of Lava crowns are the opaque core and the zirconia coping margins can be very close to the margin of the preparation. These characteristics reduce or eliminate graying at the margin due to microleakage that can be visible in more translucent restorations. During the eight-year evaluation, only 2.1% of the restorations exhibited slight graying at the margins.

​► Wear Resistance

Over 97% of Lava restorations received an excellent rating for resistance to wear. A small number (2.8%) of the recalled restorations exhibited some wear of the overlaid ceramic at eight years. Minimal to moderate wear was noted in about 15% of the teeth opposing Lava restorations; this wear was mostly visible in anterior teeth.

Lava Crowns and Bridges performed exceptionally well over the eight-year evaluation period with excellent resistance to fracture and marginal discoloration and minimal wear. Lava is proving itself to be a reliable and practice building type of restoration
