The mean denture bearing area in the edentulous mandible is approximately
1) 12.25 cm square
2) 16.25 cm square
3) 18.12 cm square
4) 20.25 cm square
Prosthodontics
Answer: 1
The denture bearing area is the part of the jawbone that supports a denture. In an edentulous (toothless) mandible, this area is crucial for the stability and retention of the denture. The mean value of 12.25 cm square is a commonly cited average for the surface area required for a well-fitting and functional lower denture. This area is important for distributing masticatory forces and providing sufficient space for denture construction.
