Extrusão ortodôntica como alternativa na obtenção de volume ósseo para cirurgia de implantes: revisão da literatura e relato de caso

Abstract

The aim of this study is to present a clinical case, reporting on the use of the orthodontic extrusion technique as an alternative for obtaining bone volume at the implant surgical site and to review the current scientific literature on the subject. This literature review sought to highlight the technique's potential for predictability and effectiveness in achieving bone gain. Searches were carried out in the PubMed database between 2019 and 2023, using the terms "orthodontic extrusion" OR "forced eruption" AND "implant", as well as a parallel search with the terms "osseointegration" and "preservation of the alveolar ridge", totaling 24 articles for the composition of the work. The clinical case presented describes an 18-year-old male patient with extensive gingival recession and resorption of the alveolar bone plate of the upper left central incisor, with indication for extraction, who was subsequently submitted to orthodontic extrusion to obtain tissue at the implant surgical site. At the end of the treatment, the technique implemented enabled a vertical bone gain of 9mm and a soft tissue gain of 2mm. Orthodontic extrusion is characterized as a promising alternative for obtaining bone volume in the context of dental implant surgery. While bone grafts have been used to correct bone deficiencies following tooth extraction, orthodontic extrusion offers a less invasive, non-surgical approach to tissue management prior to implant installation. In conclusion, the orthodontic extrusion technique proved to be an effective and predictable option for improving bone gain conditions prior to implant installation.
