Summary
New dental techniques use ceramic inserts to reduce stress in composite fillings for Class 2 defects. The SONICSYS approx system offers a novel approach combining direct restoration benefits with inlay precision for improved durability and aesthetics.
Area of Science:
- Restorative Dentistry
- Dental Materials Science
Background:
- Direct composite resin restorations for Class 2 defects face durability issues due to polymerization shrinkage stresses.
- Prefabricated ceramic inserts partially mitigate these stresses by reducing the volume of directly cured material.
Observation:
- Incorporating prefabricated ceramic inserts into composite resins can mitigate polymerization stresses by reducing the volume of directly cured material.
- The SONICSYS approx system utilizes sonically driven, diamond-coated tips to shape cavities for presized ceramic proximal inlays.
Findings:
- The SONICSYS approx system offers an intermediate technique between direct resin composite and laboratory-fabricated inlays.
- Case studies demonstrate operative innovations that enhance interfacial integrity, predictable contacts, and physiological contour.
Implications:
- This technique may improve the longevity and clinical performance of direct restorative options.
- It presents a novel approach to managing mechanical stresses in dental restorations.
