Brief Summary
In this investigation the investigators would like to find out which of two commonly used techniques of management of palatally impacted canines: closed-window (CWT) or open-window (OWT), produces more favorable outcome.

Outcome Measures
Primary Outcomes (1)
Total duration of treatment
The main study parameter will be the total duration of treatment. The beginning of the treatment will be at the moment of placement of fixed orthodontic appliances. In OWT group, the exposure of impacted canine will be performed prior to placement of fixed appliances. Nevertheless, the beginning of treatment will also be the moment of placement of fixed appliances. The end point of the study will be 6 months after completion of orthodontic treatment.
24 - 36 months
Secondary Outcomes (8)
Length of duration of surgical procedure
30 - 120 minutes
Patient's perception of pain and recovery after surgery measured on 100 mm visual analog scale (VAS)
7 days
Quality of life and satisfaction with treatment measured with Oral Health Impact Profile (OHIP) -14 questionnaire
24-36 months
Amount of root resorption of adjacent teeth
24-36 months
Periodontal status of impacted canine and adjacent teeth - pocket depths, loss of clinical attachment, and gingival recession.
24-36 months
- +3 more secondary outcomes
Study Arms (2)
OWT - open window technique
EXPERIMENTALIn this arm, a palatally impacted canine will be exposed surgically and left for max 9 months. No traction will be applied during this time.
CWT - closed window technique
ACTIVE COMPARATORIn this arm, a palatally impacted canine will be exposed surgically, an attachment will be bonded to the tooth and traction will be applied after healing period is complete (1-2 weeks).
Interventions
palatally impacted canine will be exposed and left without traction for a maximum of 9 months
palatally impacted canine will be exposed, an attachment will be bonded, and then the canine will be covered with palatal tissue; traction of the canine will be initiated within 2 weeks following surgery
