Which factors influence the choice of clasp type for an RPD?

• A. Cost and availability of materials
• B. Location of teeth, undercut availability, and retention needs
• C. Color matching and aesthetics
• D. Patient's age and medical history

Answer: (B)

The choice of clasp type for a removable partial denture (RPD) is primarily influenced by the location of teeth, undercut availability, and retention needs. The clasp selected must effectively engage the undercut of the abutment teeth to provide adequate retention and stability for the prosthesis. Each clasp design offers different levels of support and retention based on the mechanics involved, which are determined by the anatomical and clinical conditions present in the patient's oral cavity. For instance, the position of the teeth affects how the clasp can be placed and function, while the presence of undercuts on the abutment teeth is crucial for the clasp to achieve retention. Retention needs must be assessed based on the arch shape, occlusion, and functional requirements of the denture to ensure that the prosthetic device remains securely in position during oral functions such as eating and speaking. Therefore, these factors are fundamental in making an informed choice about which clasp type will work best to support the specific clinical situation of the patient.
