Which impression technique should be utilized if there are inadequate natural teeth for mounting casts?

• A. Special impression procedures
• B. Diagnostic impressions
• C. Record bases
• D. Direct techniques

Answer: (C)

Using record bases is advantageous in situations where there are inadequate natural teeth for mounting casts because they provide a stable and accurate way to support the impression material and record the maxillomandibular relationship. Record bases serve as a foundation for capturing the details of the oral cavity and can also facilitate the transfer of occlusal relationships to the articulator. This technique allows for a reliable reproduction of the edentulous arch and any remaining structures. In scenarios with insufficient teeth, record bases help in achieving a balanced representation that can guide the fabrication of the removable partial denture. By providing a solid base, it minimizes potential variability that could arise from using unsupported tissue, ensuring more accurate results that meet the necessary clinical requirements. This makes record bases particularly effective in managing cases with compromised dental support.
