Comparative Evaluation of Compressive And Flexural Strength of Newer Nanocomposite Materials with Conventional Hybrid Composites-An Invitro Study
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 12
Abstract
During the recent years, different brands of nanocomposites have been introduced and it is a matter of utmost importance to choose the one with most favorable properties. The present study aimed at comparison of compressive and flexural strength of hybrid and nanocomposites available in the market and also to compare the nanocomposites of different brands. The newer nanocomposite materials used in this study include Filtek Z350XT, Tetric N ceram & Brilliant NG. Hybrid composite include Filtek Z250. Methods: A total of 100 specimens were selected. Four groups were made of four different composite materials having 25 specimens in each group.13 in each group were subjected to compressive test and 12 in each were subjected to flexural test. The specimens were stored in distilled water at 37 ◦C, 24 h. and transferred to the universal testing machine, subjected to compressive & flexural strength analysis. Results: Filtek Z350XT had the highest compressive and flexural strength and Tetric N Ceram had the lowest Conclusion: Within the limitations of our study it can be concluded that nanohybrid resins (Tetric N Ceram and Brilliant NG ) tested presented inferior properties compared with the nanofilled composite (Filtek Z350XT).The performance of Hybrid composite Filtek Z250 was comparable to nanocomposite.
