Indications for using an embrasure clasp include which Kennedy class grouping?

• A. 0.01 inch undercut
• B. Kennedy Class II or III or IV
• C. Usually used on the side with no edentulous space
• D. 0.01 inch near side undercut

Answer: (B)

Embrasure clasps are chosen when you can gain retention by engaging an undercut located in the interdental embrasure between adjacent teeth, giving a discreet and effective retentive element for the partial denture. This approach works well in Kennedy patterns where there is an edentulous space bounded by natural teeth, which corresponds to Class II, Class III, and Class IV configurations. In those scenarios, an embrasure clasp can utilize the space between teeth adjacent to the edentulous area to resist dislodgement without relying on bulky or visible clasps on the esthetic areas. In contrast, considerations about a specific undercut size or the side choice relative to the edentulous space do not define the patient pattern the way Kennedy class grouping does, so they are not the primary indications. Therefore, embrasure clasps are indicated in Kennedy Class II, Class III, and Class IV patterns.
