2. Minimal intervention dentistry
remineralization of early lesions
reduction in cariogenic bacteria
repair of defective restorations
disease control
minimum surgical intervention (MSI)

3. Resin composite
improved esthetic qualities, strength, wear resistance and reduced water sorption
Polymerization shrinkage and microleakage is still an unsolved problem

4. PURPOSE
compare the marginal adaptation of ceramic and composite slot inlays fabricated with the Cerec 3 CAD/CAM and directly filled fine hybrid composite Class II restorations before and after thermal and mechanical fatigue testing
2 different bonding approach
