What is the primary purpose of the Dual impression technique?

The primary purpose of the Dual impression technique is to equalize support from the edentulous ridge and abutment teeth. This technique is designed to capture the relationship between the supporting structures of the mouth, allowing for a more accurate and functional impression. By obtaining a complete representation of both the soft and hard tissues in a single impression, it helps to distribute forces evenly during chewing and occlusion, ultimately resulting in a prosthesis that fits better and functions more effectively.

When the soft tissues in the impression are recorded alongside the support provided by the abutment teeth, it allows the dentist to create a removable partial denture that is both stable and comfortable for the patient. This method reduces the risk of pressure points or discomfort that could arise when impressions do not account for the unique interplay between the edentulous areas and existing teeth. The effectiveness of this technique is crucial to ensure that the final denture is well-adapted and achieves the desired functional and aesthetic outcomes.
