Leaving missing lower molars often makes upper molars extrude. Because of not enough space, making crowns on dental implants is impossible (far left photos). Applying mini-screw type implants for orthodontic treatment enables to push extruded tooth back (center photos). 5 months after the start of the intrusion treatment make the patient get enough space for the finishing crowns on the dental implants (far right photos).
