Dental adhesive systems 8 generation

talking shortly about the last generation of bonding system

1. Dental Adhesive Systems

2. Introduction Adhesive materials have undergone great progress in the last decades It has many generations which   purpose to increase the strength of bonding and reduce the number of bottles

3. 8 th   generation As we study this semester , there is 7 generations of bonding system Recently , In 2010, voco America introduced the last generation of bonding agent

4. 8 th  generation  The advantag es of 8 th  generation : 1- It’s all in 1 step : they limit the number of bottles to one like the seven generation so reducing clinical time

5. 8 th  generation 2- The thing that makes this generation significant is the use of nanosize fillers As we know, Nano-fillers with dimensions larger than 15–20 nm may cause cracks and decrease in the bond strength So they use in this bond  12 nm fillers

6. 8 th  generation The use of nanosize fillers increases the penetration of resin monomers and the hybrid layer thickness, which in turn improves the mechanical properties of the bonding systems

7. 8 th  generation 3- It has been observed that filled bonding agents produced higher bond strength 4- Longer shelf life 5-Stress absorption

8. 8 th  generation Previously ,It was a challenge to make the bond strength in self etching agents similar to total etching agents Because there is no rinse after etching so it cause sensitivity to teeth and the lower acidity of etching decrease the bond strength

9. Conclusion But now in 8 th  generation the bond strength is too acceptable to use clinically Lastly , Here is a table that show the comparison between the generations in many aspects And Absolutely THANKS FOR LISTING
