Clinical Development of a Processed Composite Resin Restoration: Preparation and Laboratory Fabrication Part I

12 INTERNATIONAL DENTISTRY SA VOL. 8, NO. 4 A dvances in the field of adhesive restorative biomaterials have resulted in adhesive restorations that provide increased retention, marginal adaptation and seal, and reduced microleakage. This evolution in adhesive dental technology has dramatically changed the way dentistry is practised in the modern dental office. Modern adhesive restorative materials and techniques now provide clinicians with more conservative treatment avenues to preserve tooth structure while improving the longevity and aesthetics of the dental restoration. From a wide range of restorative biomaterials, indirect laboratory processed composite resin systems provide an aesthetic alternative for intracoronal posterior restorations. Laboratory processed inlays and onlays fabricated with composite resin are capable of aesthetic results that may also reinforce tooth structure. Because this adhesive procedure strengthens the cusps and provides additional support for tooth structure, more conservative preparation designs can be utilized. These systems restore mechanical and biological function while achieving optimal aesthetic results with minimal resin cement shrinkage and limited tooth reduction. Additional clinical benefits include not only precise marginal integrity, wear resistance similar that is similar to enamel, and wear compatibility with opposing natural dentition but also ideal proximal contacts, excellent anatomical morphology, and optimal aesthetics. 1,2,3
