Impact of Surface Treatments on the Roughness Surface and Fracture Pattern of Zirconia Ceramic Restorations

Purpose: The aim of this study was to assess the surface roughness, and fracture pattern of zirconia ceramic restorations after the application of different surface treatments. Material and method: We conducted a systematic literature search on the electronic databases PubMed and Science direct using 12 key words via Boolean equations. We identified articles that met the eligibility criteria by checking the title and abstract. A full-text review was used to select articles based on the CASP grid. (The Critical Skills Appraisal Programme) Results: 13 articles were selected after reading the full text. We noted a predominance of mixed failure in our study. Conclusion: Sandblasting before sintering is a recommended method to increase surface roughness and improve the bond strength of the cosmetic ceramic. The mixed fracture mode is the most frequent mode in our study. Further clinical studies with standardization of protocols should be conducted.
