Though we were initially skeptical of the benefits of pure zirconia copings, a few recent cases have changed our minds. Specifically, we have had a great deal of success using zirconia copings to provide exceptional implant restorations and posterior bridges. This brings to question which restoration is best. From our experience (without the vested interest of owning any of the 3 systems), Lava seems to be clearly superior. First, the fit is consistently better. Second, the core material is shaded (great for cases with exposed linguals or tight occlusion). Third, it is much more flexible in regards to prep design (fits on almost any prep).

Given the fact that the strength of all 3 systems is identical (same raw material), it appears Lava is the current standard in pure zirconia restorations.
