Intrusion of Molars with Implants as Anchorage: A Report of Two Cases

Open publisher page 17 citations

Abstract

BACKGROUND: Osseointegrated implants do not move in response to orthodontic loads. PURPOSE: The aim of this study was to describe a method to intrude supra-erupted molars using prosthetic implants as anchorage. MATERIALS AND METHODS: A 51-year-old female and a 36-year-old male were treated with adjacent implants for orthodontic anchorage for supra-erupted teeth in the maxilla (16, 17) and in the mandible (46, 47), respectively. In both cases, the force of intrusion applied was 300 g. RESULTS: The therapy was completed without complications or abnormalities of the intruded teeth or anchorage implants. Intrusion required 13 months in the first case and 19 months in the latter. CONCLUSION: The present method makes it possible to secure enough space for prosthodontic therapy at edentulous segments and perform highly reliable implant therapy.
