What is a risk associated with micromovement in implants?

• A. Increased stability
• B. Delayed bone integration
• C. Enhanced aesthetics
• D. Reduced metal fatigue

Answer: (B)

Micromovement in implants can lead to delayed bone integration, which is a significant risk. When an implant experiences micromovement, it can prevent the bones from effectively bonding with the implant's surface. This osseointegration process is crucial for the stability and longevity of the implant. Ideal conditions for osseointegration require minimal movement to allow for direct contact between the bone and the implant, ensuring that the surrounding bone can remodel and heal effectively. If there is excessive micromovement, it can create a gap that inhibits bone growth and may even lead to implant failure.

In contrast, increased stability typically suggests that an implant is well-seated and not experiencing micromovement, while enhanced aesthetics and reduced metal fatigue are not directly influenced by micromovement.
