What does 'primary stability' refer to in dental implants?

Primary stability is a critical concept in dental implants, referring specifically to the initial mechanical stability of the implant immediately after it is placed in the bone. This stability is essential for the implant to remain in a fixed position during the early healing phase, allowing for proper osseointegration with the surrounding bone.

This initial stability is influenced by several factors, including the quality and quantity of the bone, the design of the implant, and the surgical technique used during placement. A well-placed implant that achieves primary stability minimizes the risk of micromovement, which can compromise healing and lead to implant failure.

In contrast, other options reflect different aspects of implant dentistry. Long-term integration with bone pertains to secondary stability, which develops over time as the bone fills in around the implant. Patient comfort is unrelated to the mechanical aspect of stability and focuses more on the surgical experience and post-operative care. Healing progress, while important, is distinct from the concept of primary stability, as it refers to the biological processes occurring after placement rather than the immediate mechanical state of the implant.
