Abstract

The stamp technique is a simple method to reproduce occlusal morphology by creating an index before cavity preparation. This report presents two cases of mandibular second molars with deep occlusal caries but intact occlusal anatomy. A stamp was fabricated with flowable composite resin and applied to the final composite increment procedure. Both cases showed accurate anatomical reproduction, minimal finishing and polishing, and reduced chair time. The technique is particularly useful for Class I cavities with preserved occlusal surfaces, providing functional and esthetic benefits. Despite limitations in cases with lost occlusal anatomy or polymerization stress, the stamp technique is an efficient option that enhances clinical outcomes and patient satisfaction.
