What is the benefit of a polished collar on an implant?

• A. Increased longevity
• B. Enhanced aesthetic appeal
• C. Better integration with bone
• D. Reduced inflammation

Answer: (C)

A polished collar on an implant offers better integration with bone primarily due to its smooth surface, which minimizes the risk of debris accumulation and promotes enhanced biocompatibility. The polished surface reduces friction and can help to create a more favorable environment for osseointegration—the process through which the implant fuses with the bone.

This smooth profile is less prone to micromotion and can allow bone cells to adhere more effectively, fostering a quicker and more stable integration with the surrounding bone tissue. While factors like longevity, aesthetic appeal, and inflammation are significant in overall implant performance, the specific advantage of having a polished collar relates closely to promoting a successful interface between the implant and the bone, which is crucial for the long-term success of the implant.
