Composite Restoration
Describe briefly the advantages and disadvantages of composite resin.
Answer:
Advantages of Composite Resin:
- Composites are highly esthetic restorative materials.
- Working time is quite good due to the multiple curing system.
- The placement of composites is very easy.
- They are moderately strong and durable.
- Corrosion does not occur in composites.
- Composites are easily repaired
Disadvantages of Composite Resin:
- They have high shrinkage.
- Composites are very technique sensitive.
- Composites stick to the instruments.
- They directly do not bond with tooth structure so require a dentin bonding agent.
- Composites are non-condensable.
- If restoration of composites is improperly done microleakage and recurrent caries may occur.
- Composite resins have low wear resistance as compared to metal restorations.
- The life span of composites is shorter when compared to the life span of metallic restorations.
- Composites get stained with time and can show color instability.
