Evaluation of marginal adaptation and microleakage of differant all-ceramic porcelain systems

ABSTRACT Purpose: This study evaluated the marginal adaptation and microleakage of ?n-Ceram Alumina, In-Ceram Zirconia Finesse press all-ceramic porcelain systems. Material methods: Thirty maxillary Central teeth extracted for periodontal reasons without caries cracks were divided equally into three group there was no control group; only systems compared. Sample cemented stored in distile water 24 hours. Then, they applied to a repeated thermal cycle 500 times. The samples left %5 basic fuchsin dye For rankings, all sample which cross-sections made moved metal microscope (Scherr Turico St. James/ Minn./ USA) degrees measured both palatinal vestibul regions by measuring twice with x10 enlargement at micron level. statistical evaluations values, Kruskal Wallis test has been used (p>0.05). Results: differences between are not significant (p>0.05), ?=0.05). Conclusion: system caused least leakage regions. In second place most biggest margin gap palatal region seen system, place. In- Ceram Alumina system.
