Final answer:

Mandibular molar teeth should be placed over the buccal shelf area to improve denture stability, as this area offers a stable base due to its dense bone and supports the force of occlusion.

Step-by-step explanation:

To improve denture stability, mandibular molar teeth should normally be placed over the buccal shelf area. The alveolar process of the mandible serves to anchor the lower teeth, and the anatomy of a tooth involves securing teeth in these sockets lined by gingivae and held by the periodontal ligament. The placement over the buccal shelf, which is a region of the mandible capable of supporting the force of occlusion due to its dense bone, ensures that the denture has a stable base to rest upon, thus enhancing its stability and function.
