|Official Title:||The Efficacy of Surgical Exposure With Alveolar-decortication vs. Conventional Surgical Exposure to Reduce Treatment Time for Orthodontic Alignment of Palatally Impacted Canines|
|Study Start Date :||January 2010|

No Intervention: Standard
Standard expose and bond.
Following surgical exposure of the impacted canine, additional perforations will be made in the surrounding cortical bone prior to wound closure.
Following surgical exposure of the impacted tooth, the surgeon will prepare small holes (perforations) and/or grooves in the cortical bone surrounding the exposed tooth as well as in the buccal bone.
- Velocity of tooth movement [ Time Frame: 6-8 weeks ]
The velocity of movement of the canine tooth will be recorded, from the start (buried) position until it is in the line of the arch. Measurements will be taken at each orthodontic appointment, usually 6-8 weeks apart throughtout treatment.
Distance will be measured with the use of linear measurements, impressions and clinical photographs.
- Time for alignment [ Time Frame: approx. 2 years. ]This will record the overall time for canine alignment, from its initial position to its final position when active orthodontic appliances are removed.
- Total orthodontic treatment time [ Time Frame: approx. 2.5 years. ]This will record the overall time, from placement to removal of active orthodontic appliances.
- Duration of surgery [ Time Frame: 1 day ]The duration of the surgical procedure in minutes, the time inbetween raising and closing the flap of gum tissue will be recorded.
- Adverse effects of surgery [ Time Frame: approx. 2.5 years. ]
