Occlusal discrepancy after direct restorations often leads to discomfort to the patients. Newer methods are developed to overcome the previous problems and to reduce the time required. A stamp technique is proposed which is an easy procedure to recreate accurate occlusal topography for a direct composite resin restoration effectively and efficiently. This technique is indicated when the preoperative anatomy of the tooth is intact and not destructed or lost due to the carious lesion.

| Introduction|| |
The search for excellence in dentistry has become constant and esthetic standard is increasingly demanding even in posterior segment. The most common location of dental caries is at occlusal level.
Morphofunctional reconstruction of the initial occlusal relief destroyed by caries through direct techniques can be a challenging task to the dentist, as it requires much skill and time in order to be satisfactorily accomplished. Such requirement can be achieved through “stamp technique.”
This new technique of stamp includes fabrication of an index which is made before the cavity preparation and can be considered as a negative replica of the occlusal topography. The obtained index is then pressed against the final composite increment before. However, such replication technique is dependent on intact occlusal morphology. The preoperative occlusal morphology provides an ideal index for replication of esthetic along with proper function.
The advantage of using this stamp technique is the reproduction of original occlusal anatomy and occlusion which does not require any further correction. Time needed for finishing and polishing of the restoration is also reduced.
| Case Report|| |
A 17-year-old male patient reported to us for the treatment of lower right first molar. The clinical examination showed the presence of dark pigments on pits and shading on the surface of the mandibular right first molar, without evidence of cavitation.
The patient did not have pain and sensitivity, and the tooth was vital. As only the occlusal surface of the tooth was involved, we opted for stamp technique for composite resin restoration in mandibular right first molar.
The tooth was isolated with rubber dam followed by the application of petroleum jelly as barrier onto the tooth surface [Figure 1]a. A stamp was made with flowable composite on occlusal surface of tooth. The microbrush was used and immersed in the composite, and polymerization was done through light curing for stamp [Figure 1]b and [Figure 1]c. The carious lesion was removed and Class 1 cavity was prepared [Figure 1]d. Etching was done for 30 s and air-dried with three-way syringe. After that, a bonding agent was applied and light cured for 20 s. Incremental technique for composite restoration was followed up to 1 mm lower to that of occlusal surface and light cured for 20 s. Later, the last layer of composite was applied and Teflon tape was placed [Figure 1]e. The stamp was then placed on Teflon tape and was removed. The excess material was removed and it was then cured [Figure 1]f. Minimal finishing and polishing of the restoration was done and occlusion was checked [Figure 1]g and [Figure 1]h.

| Discussion|| |
Posterior teeth with primary carious lesions may present an intact occlusal morphology. With little or no damage to the enamel, there is destruction of the dentin. To reach the infected dentin, a sufficient amount of healthy enamel has to be removed. In this lies the concept of using a composite stamp before the operative procedure for such kind of initial lesion.,
The reduced overall time due to almost instantly desired good cusp–fossa relationship is the major advantage of this technique. As the stamp matrix exerts pressure on the composite, there is reduction of porosity in final restoration along with decrease in the formation of microbubbles and interference of oxygen during polymerization of composite.
With the minimal time required for finishing to obtain a good fossa–cusp relationship with the opposing dentition, stamp technique is suitable in a busy practice dealing with many patients.
It is advantageous because less time is required to recreate occlusal anatomy, material consumption is less, decreased chairside time, replicates original occlusal anatomy, and no need of special instruments.
Disadvantages of the technique includes falling of stick, i.e., breakage of stamp, and cost of flowable composite.
Other cost-effective materials could be considered as follows: pit and fissure sealants, poly methyl methaacrylate, pattern resin, gingival dam material, vacuum formed template, and bite registration material.
| Conclusion|| |
The stamp technique provides an easy approach to restore with accurate topography, less postfill adjustments, and less time. The accuracy of topography replication is greater than the manual method and can be adapted to unconventional cavities as well.
