Impacted canine causes many problems for patients, such as damage to the adjacent teeth roots, effects on gingival tissues, aesthetic problems, difficulty, and prolonged orthodontic treatment duration. Therefore, solutions to accelerate the movement of impacted canines with the help of surgical procedures to reduce treatment time will be investigated, such as intra-operative alveolar perforations and piezocision. We also aimed to evaluate periodontal changes associated with such accelerating procedures compared with the conventional traction method.
Patients with palatally impacted maxillary canines will be treated using fixed appliances assisted by some surgical procedures. The effects of this treatment approach on the periodontal status will be assessed using periodontal measurements. There are two groups : 1. conventional treatment group 2. minimally-invasive corticotomy-assisted treatment group Patients will be allocated to the two groups randomly. Data will be collected using periodontal variables.

Metal brackets with a straight-wire prescription will be used. Patients will be treated conventionally.
Patients will be treated in conjunction with a surgical intervention using metal brackets with a straight-wire prescription. Corticotomy (alveolar perforation and piezocision) will induce acceleration in canine traction movement during the orthodontic treatment in only one group.

Changes in the periodontal pocket depth (PPD)
The distance from the gingival margin to the base of the pocket of the first premolar, canine, and lateral incisor.
Time frame: Time 1: immediately before the surgical exposure; Time 2: immediately at the end of the active treatment
Changes in the gingival margin (GM)
The distance from the cementoenamel junction (CEJ) to the gingival margin of the first premolar, canine, and lateral incisor.
Time frame: Time 1: immediately before the surgical exposure; Time 2: immediately at the end of the active treatment
Changes in the width of the keratinized tissue (KT)
The distance from the gingival margin to the mucogingival junction of the first premolar, canine, and lateral incisor
Time frame: Time 1: immediately before the surgical exposure; Time 2: immediately at the end of the active treatment
Changes in the Gingival Index (GI)
The gingival status will be assessed using the following classification 0= Normal gingiva. 1. Mild inflammation: slight color change, slight edema, No bleeding on probing. 2. Moderate inflammation: redness, edema and glazing. Bleeding on probing. 3. Severe inflammation: marked redness and edema. Tendency to spontaneous bleeding. Ulceration.
Time frame: Time 1: immediately before the surgical exposure; Time 2: immediately at the end of the active treatment
Changes in the Bleeding Index (BI)
The healthiness of the gingival margin and the attached gingivae will be assessed depending on the status of gingival inflammation. 0= No bleeding. 1. Bleeding some seconds after probing. 2. Bleeding immediately after probing. 3. Bleeding on probing spreading towards the marginal gingiva.
Time frame: Time 1: immediately before the surgical exposure; Time 2: immediately at the end of the active treatment
