The Rate of Space Closure With Piezocision-based Corticotomy in Different Facial Types: A Split-mouth Design (RCT)
Class II Div 1 Malocclusion
About this trial
This is an interventional screening trial for Class II Div 1 Malocclusion focused on measuring Canine retraction, Space closure, Rate of tooth movement, Facial divergence, Piezocision
Eligibility Criteria
Inclusion Criteria:
- Young adults and adults (15-29).
- Middleastern Caucasian.
- Females.
- Having the defined orthodontic appliance, slot size, prescription, and technique of space closure.
- Class II division I of moderate space requirement that is planned to have the first premolar extracted.
- Average or high facial type.
- Healthy patients without systematic diseases that could affect bone and tooth movement and no contraindication (medical or psychological) to avoid oral surgery.
- No active periodontal diseases as this effect the cytokines expression (stabilized prostaglandin (PG) health)
- Good oral hygiene.
- No other method of non-surgical acceleration technique to be used.
Exclusion Criteria:
- Patients who refused to consent for the study.
- The two extremes of age (younger than 14 and older than 29).
- Having other than the defined orthodontic appliance, slot size, prescription, and technique of space closure.
- Extraction cases of high space requirements or other teeth than the first premolar.
- Patients with systematic diseases that could affect bone and tooth movement and no contraindication (medical or psychological) avoid oral surgery.
- Active periodontal diseases.
- Other methods of non-surgical acceleration technique to be used.
