What is the best configuration for the implants used in a removable denture for the mandible?

The optimal configuration for the implants used in a removable denture for the mandible is curvilinear. This configuration allows for a more anatomical alignment that can enhance the support and retention of the overdenture.

In the mandible, a curvilinear arrangement of implants based on the shape of the residual ridge effectively distributes the masticatory forces. It helps in achieving better stability for the removable denture, as it aligns with the curve of the mandible, optimizing the surface area for the retention of the prosthesis.

Additionally, this configuration can accommodate the biomechanical requirements of the mandible while minimizing stress on the implants. It allows for better communication between the implants and the surrounding bone, promoting osseointegration and long-term stability.

In contrast, implants placed in a transverse or straight vertical alignment may not conform to the anatomical contours of the mandible, potentially leading to uneven load distribution and compromising the denture's function and comfort. The lateral arrangement could also cause issues with stability, as it might not provide the best mechanical advantage for supporting the denture. Therefore, the curvilinear approach is favored for its ability to enhance the overall performance and longevity of removable dentures in the mandible.
