Zirconia and high-resistant ceramics are gaining popularity in the US market for dental restorations. Studies show complication rates of 5% to 16% after 5 years of use. 1,2,3 Main issues include chipping and fractures due to microcracks in zirconia. Choosing the right instruments for adjustment is crucial for ensuring longevity and clinical success.12

What Burs Are Recommended for Adjusting Zirconia?

Studies have shown that using coarse diamond burs and carbides can weaken zirconia[4,8,13,22] causing surface microcracks[6] and reducing its flexural strength[5]. This can lead to fractures[14,16] during loading. Moreover, these instruments leave rough surfaces that are difficult to polish effectively[10] increasing abrasion[11] on opposing teeth and bacterial retention[10]. SEM pictures highlight that not all diamond burs for zirconia are suitable for zirconia adjusting, emphasizing the importance of choosing the right tools for optimal results.

Why Is Zirconia Polishing an Essential Step?

enhances zirconia's flexural strength15 -> increases restoration longevity

reduces surface roughness 9,12 -> improves aesthetics and gloss

decreases biofilm accumulation -> decrease secondary caries

minimizes wear on opposing teeth7,11

creates a delightful, smooth sensation for patients

the polished surface does not crack like glaze

many studies revealed glazed monolithic crowns cause more wear than polished ones 21,24,25,26
