The wash impression technique is one of the most frequently used in the daily practice. One of the main drawbacks is the need to ensure adequate space for the corrective phase.
Aim: Modification and improvement of an existing method, with which adequate space around the prepared teeth is freed, ensuring a guided flow of the corrective silicone impression material.
Materials and methods: After the stage of preparation a composite resin material with low viscosity Metaflow (Metabiomed) is applied in the area of the cervical area and inside the gingival sulcus. The material is light cured following with the first impression alongside the putty phase OrmaPlus (Major, Italy), is applied. The light cured material – composite rings, is included in the first impression. Their removal ensures even quantity of the corrective material Sushy4 (Bisico, Germany), in the following impression phase.
Results: We have ensured sufficient corrective layer that reproduces the exact details of the preparation border.
Conclusion: The ease of use of the modified technique, makes it applicable when single and multiple teeth are prepared.
