Direct bonding of unerupted teeth for orthodontic movement

Periodontal Health of Orthodontically Extruded Impacted Teeth. A Split‐Mouth, Long‐Term Clinical Evaluation

“…14,15 With the introduction of the acid-etch technique, the surgical exposure of the unerupted crown could be limited to an area sufficient to accommodate the base of the orthodontic attachment. 16,17 It was our hypothesis that a technique in which the area of surgical exposure was kept to a minimum to accommodate a mini eyelet, in combination with careful orthodontic management of the extrusion, would have no detrimental effect on the periodontal health status of either the extruded tooth or its neighbors. The aim of this retrospective study was to evaluate the long-term periodontal outcome of a combined periodontal-orthodontic approach (closed eruption applying the acid etch-technique and conservative surgery) as treatment for impacted teeth in comparison with spontaneously erupted contralateral teeth.…”
