Massive intrusion of maxillary second molar for prosthodontic purposes through miniscrew-supported biomechanics and fixed partial appliances: A case report

Int Orthod. 2022 Jul 19:100662. doi: 10.1016/j.ortho.2022.100662. Online ahead of print. ABSTRACT 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…

Comparative analysis of intraoral scanners accuracy using 3D software: an in vivo study

Prog Orthod. 2022 Jul 4;23(1):21. doi: 10.1186/s40510-022-00416-5. ABSTRACT BACKGROUND: The purpose of the present in vivo study was to compare the accuracy, in terms of trueness, between full-arch digital impressions of different intraoral scanning systems, using as a reference the ideality of the conventional impression technique. METHODS: Polyvinyl siloxane (PVS) two-step technique impressions of 27…
