lüll An alternative method to reduce polymerization shrinkage in direct posterior composite restorations Deliperi S; Bardwell DNJ Am Dent Assoc 2002[Oct]; 133 (10): 1387-98BACKGROUND: Polymerization shrinkage is one of dental clinicians' main concerns when placing direct, posterior, resin-based composite restorations. Evolving improvements associated with resin-based composite materials, dental adhesives, filling techniques and light curing have improved their predictability, but shrinkage problems remain. METHODS: The authors propose restoring enamel and dentin as two different substrates and describe new techniques for placing direct, posterior, resin-based composite restorations. These techniques use flowable and microhybrid resin-based composites that are polymerized with a progressive curing technique to restore dentin, as well as a microhybrid composite polymerized with a pulse-curing technique to restore enamel. Combined with an oblique, successive cusp buildup method, these techniques can minimize polymerization shrinkage greatly. CONCLUSIONS: Selection and appropriate use of materials, better placement techniques and control polymerization shrinkage may result in more predictable and esthetic Class II resin-based composite restorations. CLINICAL IMPLICATIONS: By using the techniques discussed by the authors, clinicians can reduce enamel microcracks and substantially improve the adaptation of resin-based composite to deep dentin. As a consequence, marginal discoloration, recurrent caries and postoperative sensitivity can be reduced, and longevity of these restorations potentially can be improved.|*Dental Restoration, Permanent/classification/methods[MESH]|Acid Etching, Dental[MESH]|Adolescent[MESH]|Composite Resins/*chemistry/classification[MESH]|Dental Bonding[MESH]|Dental Caries/therapy[MESH]|Dental Cavity Preparation/classification[MESH]|Dental Enamel/ultrastructure[MESH]|Dental Polishing[MESH]|Dentin-Bonding Agents[MESH]|Dentin/ultrastructure[MESH]|Esthetics, Dental[MESH]|Female[MESH]|Humans[MESH]|Light[MESH]|Matrix Bands[MESH]|Molar[MESH]|Polymers[MESH]|Rubber Dams[MESH]|Surface Properties[MESH]|Viscosity[MESH] |
