Ante's law, a classic guiding principle in fixed prosthodontics, states that:

  1. The combined root surface area of the abutment teeth supporting a fixed partial denture (bridge) should be equal to or greater than the root surface area of the teeth being replaced
  2. The combined crown height of abutment teeth must exceed that of the pontic
  3. Implants should always be splinted together regardless of number
  4. Removable partial denture clasps must always engage at least two undercuts
Show answer and explanation

Correct answer: A. The combined root surface area of the abutment teeth supporting a fixed partial denture (bridge) should be equal to or greater than the root surface area of the teeth being replaced

Ante's law guides fixed partial denture (bridge) design, stating that abutment teeth should collectively have at least as much root surface area as the teeth being replaced by the pontic(s), helping ensure the abutments can withstand the additional functional load.
