What is the shape of the tapered internal hex implant body?

• A. Cylindrical
• B. Straight
• C. Anatomically tapered
• D. Uniform diameter

Answer: (C)

The tapered internal hex implant body is designed with a specific anatomical shape that mimics the natural contours of the tooth roots. This anatomical taper allows the implant to provide enhanced stabilization within the bone, improving osseointegration and mimicking the natural taper of teeth. The taper also helps in reducing the amount of bone required for placement and can facilitate insertion in areas with limited space.

In contrast, other shapes such as cylindrical and uniform diameter implants do not provide the same benefits as they lack the anatomical adaptation to the bone structure, making them less effective in certain clinical scenarios. Additionally, a completely straight design would not accommodate the natural variations in the alveolar ridge as effectively as a tapered design would. Thus, the tapered internal hex implant's anatomical taper provides functional advantages that are essential for successful implant therapy.
