It is a widely held truism in the surgical disciplines in medicine that a surgeon needs to complete between 50 and 100 procedures to be considered competent. The real evidence for this is somewhat less clear. Jerjes and Hopper (2018) described a number of investigations into the relationship between experience and postoperative outcomes in both medical and dental surgical disciplines. Their review found no consistent relationship between these factors. However, it did find evidence that there was often a threshold level of experience below which surgeons could be expected to have greater incidence of problems, indicating that there was a “learning curve” related to most surgical procedures. This threshold value varied between disciplines and studies.

In a systematic review of the relationship between surgeon experience and implant failure rates, Sendyk and others (Sendyk et al, 2017) noted that this relationship did not correlate with the surgeon’s specialty but was significantly related to the number of implants that the surgeon had placed. In an earlier study, Lambert and coworkers (Lambert et al, 1997) found similar outcomes, noting that implant failure rates were two times higher for inexperienced surgeons (ie, who had placed less than 50 implants) compared to those of surgeons who had placed 50 or more implants. They also noted that the first nine implants placed by a surgeon under training where at the greatest risk of failure. These findings could be reasonably accepted as showing a relationship between experience and outcomes in implant treatments.
