MY BEST DIRECT CASE
Direct Resin Buildup Technique
Marcos Vargas, DDS*
• Composite resin materials forthis technique must have han-dling characteristics that allowplacement in the restorativesite without slumping.
• Two increments of nanocom-posite resin (ie, Filtek SupremePlus, 3M ESPE) were placedsimultaneously and contouredto optimal proportion on themesial aspect of the centrals.
• A matrix was placed betweenthe central incisors; compositewas layered against the matrixlingually and pulled throughtoward the facial to ensureproper contour.
• Finishing and polishing wereperformed to render finalanatomy and luster using a #12blade, SofLex disks (3M ESPE),and polishing cups and strips.
