Class II direct composites

Dr Deliperi has introduced a stress-reducing approach for the restoration of Class II direct composites since 2002 in an attempt to mimic the functional and optical characteristics of the intact natural tooth (Deliperi S. & Bardwell, JADA 2002). The goal of Stress-reduced Direct Composite (SRDC) restorations is to maximize the bond and minimize the stress from both polymerization shrinkage and occlusal loading.

The restoration of Class II direct composite is completed following a minimally invasive step-by-step protocol: 1. Analysis of the occlusion and opposing dentition; 2. Cavity preparation and caries removal endpoints; 3. Analysis of residual tooth structure; 4. Preparation of the dental substrate to achieve a reliable bond to enamel and dentin; 5. Control of polymerization stresses by using appropriate layering and curing techniques; 6. Occlusal force equilibration (Deliperi S. Operative Dentistry 2012).

The SRDC protocol has been adopted to predictably restore structurally compromised posterior teeth for many years (Deliperi S. Journal of Esthetic & Restorative Dentistry 2006, 2008). When most of the dentinoenamel complex (DEC) on the lateral and proximal walls of severely structurally compromised teeth is lost, the “wall-papering” of the residual cavity walls with polyethylene fibers may help to both emulate the crack shielding mechanism of the DEC and absorb the stress from either polymerization shrinkage or occlusal load (Deliperi S. et al. Operative Dentistry 2017).
By using a similar approach, fiber-reinforced stress-reduced direct composite restorations may be performed in the restoration of structurally compromised vital and devital teeth.”[/vc_column_text][/vc_column][/vc_row]
