What is one common reason a surgical stent might fit well while an immediate denture does not?

• A. Differences in material used
• B. Incorrect impression technique
• C. Gender differences in anatomy
• D. Timing of fabrications

Answer: (B)

The answer highlights a crucial aspect of prosthetic fitting, specifically in the context of dental applications. An immediate denture relies heavily on the accuracy of the impression technique because it is created to match the specific contours and tissue of the mouth after tooth extraction. If the initial impression is not taken correctly—because of factors like an inadequate seal, improper positioning, or lack of detail—it can lead to a poorly fitting denture.

In contrast, a surgical stent, often used in dental implant procedures, is generally made to guide the placement of implants based on a pre-surgical plan or imaging. The materials and design of a stent are typically more forgiving, allowing for slight variations in fit due to the nature of surgical procedures. Therefore, the impression technique's accuracy is fundamentally significant for immediate dentures, making this choice the most logical reason for the disparity in fit compared to surgical stents. Understanding this distinction emphasizes the importance of technique and precision in the creation of dental prosthetics.
