COMBINING ORTHODONTIC EXTRUSION AND GUIDED BONE REGENERATION (GBR) FOR BONE AUGMENTATION AND IMPLANT PLACEMENT IN THE AESTHETIC ZONE: TECHNICAL ISSUES AND CASE REPORT

Abstract

Orthodontic extrusion is a non-surgical technique used to vertically augment bone ridges by extruding impaired teeth and then replacing them with dental implants. Both the volume of bone and the height of the gingiva are increased by means of this intervention, affording considerable benefits when aesthetic zones are being treated. Orthodontic extrusion can be combined with bone regeneration methods, and this is particularly useful in cases of vertical and horizontal bone loss. Guided bone regeneration (GBR) involves the use of a barrier membrane to keep a space free for a blood clot to form, while keeping epithelial cells and connective tissue fibroblasts at bay, thus promoting the generation of new bone tissue. The present case report describes a challenging aesthetic rehabilitation performed in a 50-year-old woman suffering from severe external resorption of the left superior second incisor. A multidisciplinary approach was adopted, achieving good functional and aesthetic results.
