Which factor is most crucial in evaluating implant success?

The most crucial factor in evaluating implant success is the long-term stability and integration of the implant. This refers to how well the dental implant merges with the jawbone and maintains its position over time. Successful osseointegration is essential because it ensures that the implant is securely anchored, allowing for the effective function of the replacement tooth or teeth.

If an implant does not achieve proper stability and integration, it can lead to implant failure, which may necessitate further procedures and negatively affect the patient's oral health. In contrast, while patient comfort during the procedure, cost-effectiveness, and the time taken for the surgical process are important considerations, they do not directly impact the biological and functional success of the implant in the long term. The ultimate goal of dental implants is to provide lasting support and functionality, making the assessment of their stability and integration paramount.
