Which dental implant was primarily used by Biohorizons in 1997?

• A. Internal hex implant
• B. External hex implant
• C. Conical implant
• D. Cylindrical implant

Answer: (B)

In 1997, Biohorizons primarily utilized the external hex implant design. This system was known for its simplicity and reliability in providing a stable connection between the implant and the abutment. The external hex feature allowed for easy alignment and placement, which contributed to its popularity among dental professionals.

The external hex implant design helps in reducing the risk of micromovement, which can be crucial for implant stability during healing. Additionally, this type of connection facilitates the use of various abutment types, essentially giving practitioners flexibility in treatment options. This design became foundational in implant dentistry during that era, setting the stage for advancements and variations in later years.

In contrast, other implant designs like the internal hex, conical, and cylindrical implants, while significant in their own right, were either not as commonly used by Biohorizons at that time or represented advancements that came later. Understanding the historical context and design features of these implants is essential for appreciating their roles in the development of implant dentistry.
