Correct answer: D — The total root surface area of abutment teeth must equal or exceed that of the teeth being replaced
Ante's law (1926) states that the total periodontal membrane area (root surface area) of the abutment teeth supporting a fixed partial denture must be equal to or greater than the total periodontal membrane area of the teeth being replaced by the pontic(s). While this is an important guideline, it is not absolute — clinical factors such as bone support quality, crown-to-root ratio, and occlusal forces also influence prognosis.
