Patients at the Orthodontic Department of the University of Damascus Dental School will be examined and subjects who meet the inclusion criteria will be included. Then, initial diagnostic records (diagnostic gypsum models, internal and external oral photographs, and radiographic images) will be studied to ensure that the selection criteria are accurately matched. This study aims to compare two groups of patients with moderate crowding of the lower anterior teeth. Experimental group: the patients in this group will be treated with periodontally accelerated osteogenic orthodontics Control group: the patients in this group will be treated using fixed appliances without any acceleration method.
Correction of irregular teeth can take a long time, and this depends on various factors such as the good compliance of the patient, the amount of dental crowding, and the need for extraction in the course of orthodontic treatment. Many methods have been used to accelerate tooth movement, and recently the PAOO technique has emerged as an effective therapeutic intervention. PAOO is a promising procedure but only a few cases were reported in the literature. Controlled clinical and histological studies are needed to understand the biology of tooth movement with this procedure, the effect on teeth and bone, post-retention stability, measuring the volume of mature bone formation, and determining the status of the periodontium and roots after treatment.

Change in Little's Index of Irregularity
The irregularity of the lower incisors is calculated by measuring the amount of deviations of the anatomic contact points between the six anterior teeth in the horizontal direction in mm, since the sum of these measurements represents the value of the index (Little, 1975). The ordinary orthodontic treatment aims to keep this Index less than 1 mm at the end of treatment.
Time frame: T0: one day before the beginning of treatment; T1: after 1 month; T2: after 2 months; T3: after 4 months; T4: after 5 months; T5: at the end of the alignment stage which is expected within 5 - 6 months
Change in the inter-canine width
The distance between the cusp tips of the lower canines. This variable will be measured on plaster models.
Time frame: T0: One day before the beginning of treatment; T1: at the end of the alignment stage
Change in the inter-2nd premolar width
The distance between the central fossae of the lower second premolars. This variable will be measured on plaster models.
Time frame: T0: One day before the beginning of treatment; T1: at the end of the alignment stage
Change in the Gingival index
Measured by degrees at each tooth: (0) Normal gingival; (1) mild inflammation; (2) Moderate inflammation; (3) severe inflammation
Time frame: T0: One day before the beginning of treatment; T1: at the end of the alignment stage
Change in the Plaque index
Measured by degrees at each tooth: (0) No plaque; (1) thin plaque layer; (2) moderate plaque layer; (3) severe plaque along the gingival margin
Time frame: T0: One day before the beginning of treatment; T1: at the end of the alignment stage
Change in the Papillary Bleeding Index
Measured by the severity of any bleeding: (0) No bleeding; (1) a single discreet bleeding point; (2) several isolated bleeding points; (3) the interdental triangle fills with blood shortly after probing; (4) profuse bleeding occurs after probing.
Time frame: T0: One day before the beginning of treatment; T1: at the end of the alignment stage
