Routine pre- and post-treatment records will be taken. The burden of each treatment is for the patient the same.

To our knowledge, there is no sound scientific information available on which to base a treatment decision. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The CWT and OWT are current treatment techniques. The secondary outcome measures will be: (1) duration of surgical procedure, (2) patients perception of pain and recovery after surgery, (3) burden of care, (4) cost-effectiveness, (5) quality of life and satisfaction with treatment, (6) degree of root resorption of the lateral incisor, (7) periodontal status of impacted canine and adjacent teeth, (8) esthetic outcome, (9) need for endodontic treatment of the impacted canine or adjacent lateral incisor, (10) occlusal outcome (evaluated with PAR index). Main study parameters/endpoints: The main outcome measure will be the total duration of treatment (including also orthodontic treatment) with two techniques of management of impacted canines. Intervention: One group will be treated with the CWT and the other group with the OWT. Study population: The case group consists of healthy persons of 11-17 years old who have unilateral palatally impacted canines. The randomization is by canine, not by patient. Study design: A randomized clinical multicentre trial with a two-group design. If you have closed tabs since closing the window, you will ne. It basically means whatever window you last closed, the size and position you had chosen for it, will be used for the next window you open. So, in that case, Ctrl+Shift+T will achieve the same result. Windows 7 and 10 will remember the last window closed (of a single program) as a global position. Our null hypothesis is that there is no difference in the outcome of exposed impacted maxillary canines after CWT or OWT. Answer (1 of 18): If the last thing you have done is to close the chrome window, if you right click on a tab, the drop-down menu will have the option reopen closed window. To our knowledge, there is no evidence-based information that would suggest, which of the two techniques results in a better outcome.

Rationale and objective: Two techniques for exposing palatally impacted canines are routinely used, the closed window technique (CWT) and the open window technique (OWT).
