Massive Intrusion of Maxillary Second Molar for Prosthodontic Purposes Through Miniscrew-supported Biomechanics and Fixed Partial Appliances: A Case Report

This clinical case demonstrates how the use of a hybrid approach consisting of aligners, orthodontic miniscrews and partial fixed appliances can be an effective and efficient solution for recovering adequate vertical space for satisfactory implant-prosthetic rehabilitation. Specifically, massive intrusion of an upper second molar (tooth 1.7) was achieved orthodontically with direct TADs support to allow otherwise unpredictable movements and achieve maximum anchorage control for subsequent implant rehabilitation of the fourth quadrant.
