Effect of the application of surface treatments before and after sintering on the flexural strength, phase transformation and surface topography of zirconia

Conclusions Application of surface treatments at pre-sintered stage may be detrimental for zirconia ceramics in terms of flexural strength. Clinical significance Treating the surface of zirconia ceramic before sintering process is not recommended due to significant decrease in flexural strength values. 2W − 4W Er,Cr:YSGG laser irradiations can be regarded as alternative surface treatment methods when zirconia restoration would be subjected to veneer ceramic firing procedures.
