Versatility of different force delivery systems from ridge mini-implants. A Intrusion of an adjacent premolar to the ridge mini-implant that had supraerupted into the edentulous antagonistic maxillary premolar region. Intrusive force delivered by means of a deflected nickel-titanium wire. B Post-intrusion occlusal relationship. C Transverse force delivery with a cantilever system driven from an alveolar ridge mini-implant in an edentulous left first molar site. D Midline correction by means of this transverse force. E Canine transverse correction with lingually directed force delivery from the cantilever system observed in C and D. F Asymmetric force delivery from a ridge mini-implant in the left premolar region for incisor plane cant correction by means of an intrusive force from a cantilever system. G Retraction of the anterior teeth from a posterior fully edentulous site with a ridge mini-implant
