Both techniques had mucoperiosteal flaps raised and bone removed above the PDCs. In open exposure, tissue was removed above the canine, and glass ionomer \u2013 reaching above soft tissue \u2013 was built on the crown. The canine was then left to erupt spontaneously, prior to orthodontic alignment. At closed exposure, a chain was bonded to the canine and orthodontic traction was applied under the mucosa until eruption. Orthodontic alignment of the canines was undertaken after eruption into the oral cavity, with fixed appliances in both groups. All participants were treated according to intention to treat (ITT).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Blinding<\/jats:title>\n                  <jats:p>Due to the nature of this trial, only outcome assessors could be blinded to the intervention group.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>One hundred and seventeen patients completed the trial.
