Generally, people are encouraged to avoid placing anterior implants at the age of 18 or younger. The age at which bone growth completes varies widely from patient to patient. The common growth spurt happens at 12 years for girls and at 14 years for boys. However, this age can vary by as much as 6 years. Thus, when planning for the placement of dental implants in a child, this problematic age period extends from 9 to 15 years for girls and 11 to 17 years for boys. Other studies indicate that for some people, the best long-term esthetics will be achieved after reaching the age of 25 when their jawbone has finished growing.
