ABSTRACT Statement of problem protective and restorative dentistry's basic function is to protect the continuity and integrity of the tissues and to restore function, phonation, and esthetics lost due to any cause. The success of dental ceramics is affected by flexural strength, but little data are available on their clinical performance. Purpose: This study evaluated the flexural strength of the İn-Ceram Alumina, In-Ceram Zirconia, and Finesse press all-ceramic porcelain systems. The success of dental porcelains is partly related to their flexural strength. The values of flexural strength of three porcelain Systems were measured to include In-Ceram Alumina, In-Ceram Zirconia, and Finesse press all ceramic porcelain systems. Material and methods: The flexural strengths of the three porcelain systems were determined by employing the method ISO specification 6872. For the statistical evaluations of the flexure strength values, Kruskal Wallis and Mann-Whitney U tests were used. Results: When the flexural strengths of In-Ceram Alumina, In-Ceram Zirconia, and Finesse groups were compared, the differences were found to be statistically significant. Conclusion: The highest flexural strength was observed for In-Ceram Zirconia, followed by In-Ceram Alumina and Finesse porcelain system. Clinical implications: In this in vitro study, In-Ceram Alumina, In-Ceram Zirconia, and Finesse all-ceramic systems were compared concerning flexural strength. The differences between the groups are significant (p<0.05).
