What is the body type of the internal hex implant?

• A. Curved wall
• B. Conical wall
• C. Tapered wall
• D. Parallel wall

Answer: (D)

The internal hex implant features a parallel wall design that is fundamental to its functionality and stability within the bone. This type of wall configuration allows for better distribution of forces during both the placement of the implant and subsequent loading after restoration. The parallel walls provide a larger surface area for osseointegration, which helps secure the implant effectively within the surrounding bone tissue.

This design also facilitates the use of various abutments and components that can be attached to the implant, enhancing versatility in different clinical situations. Additionally, the internal hex feature allows for better mechanical interlocking with the abutment, reducing the risk of screw loosening or failure.

Other designs, such as tapered or conical walls, serve distinct purposes in different types of implants but are not characteristic of the internal hex implant design. These configurations might influence the initial stability or the ease of placement in varying bone densities, but they lack the specific advantages provided by the parallel wall structure of the internal hex system.
