Pseudo-implantation in infants is a condition in which the lower front teeth overshadow the upper front teeth in a pseudo-implantation of the lower jaw before the normal occlusion of the upper and lower teeth is fully established. The lack of guidance from the cusps of the baby teeth before they are fully erupted leads to an unstable relationship between the position of the lower jaw, which, combined with poor oral habits or improper feeding practices, can easily lead to pseudophakic eruption. This phenomenon occurs when the bottle is incorrectly positioned during manual feeding, and the baby will deliberately extend the jaw forward to wrap the pacifier, which will result in pseudo-implantation after a long time. In addition, poor upper lip biting and biting habits can also cause pseudophakic dystocia. As long as the position of the bottle and the infant’s bad mouth habits are corrected in time, the phenomenon of pseudophakia will disappear quickly.
