The Effectiveness of Double-slot Brackets Versus Single-slot Brackets on the Rate of Canine Retraction
Trial Parameters
Brief Summary
The aim of this Randomized clinical trial is to compare the efficacy of the double slot brackets compared to single slot-brackets in producing a controlled rate of upper canine retraction into premolar extraction space. patients will be randomly divided into one of the two groups, CBCT (cone beam computed tomography) and dental models will be taken for each patient Pre-retraction and following the study completion. The rate of retraction will be evaluated for both groups as well as Amount of canine root movement and molar anchorage loss will be also assessed.
Eligibility Criteria
Inclusion Criteria: * Good oral hygiene. * Adult Male or Female patients with an age range of 16-26 years old. * Full set of permanent dentition(excluding third molar). * Any kind of malocclusion requiring first premolar extraction and canine retraction. * Patients with type/pattern of crowding that allows leveling and alignment before premolar extraction Exclusion Criteria: * History of previous orthodontic treatment. * Craniofacial deformity. * Systematic disease or administrating drugs affecting tooth movement. * Poor oral health.
