Which is not a criterion for an implant considered to be successful?

Successful dental implant outcomes are evaluated based on several key criteria that indicate not just the stability and functionality of the implant, but also the health of the surrounding tissues and overall patient satisfaction. Rigid fixation is essential, as it ensures that the implant remains securely anchored, allowing for proper load distribution during function.

A critical factor is the management of crestal bone loss after an implant is placed. Successful implants typically show less than 0.2mm of bone loss in the first year of function, which signifies a healthy integration between the bone and the implant without significant degradation of the surrounding bone structure.

The esthetic outcome is another important criterion, reflecting the implant's appearance in relation to the natural teeth and the overall dental arch. A pleasing esthetic result can enhance patient confidence and satisfaction, thereby contributing to the long-term success of the implant.

On the other hand, having probable pocket depths of 7mm is not indicative of a successful implant. Typically, successful implants should demonstrate much shallower pocket depths, ideally around 4mm or less. Pocket depths of 7mm may suggest periodontal issues, which can lead to complications and jeopardize the stability of the implant.

Thus, while the other criteria reflect characteristics of a successful implant, having deep pocket depths
