结局指标
主要结局
Measurement of buccal bone thickness
时间窗: 3 months
buccal bone thickness will be measured from the CBCT scans. Three points will be measured from the buccal bone to the root, at the coronal, mid-root, and apical level
Measurement of alveolar bone microstructure
时间窗: 3 months
From the CBCT scans, the maxillary alveolar process between the canine and lateral incisor, and between the canine and second premolar will be examined. Bone microstructures will be measured and calculated with a dedicated software.
Measurement of alveolar bone density
时间窗: 3 months
Bone density will be measured from cone beam computed tomography (CBCT) scans at 2 different locations on each side of the upper arch; between the canine and lateral incisor, and between the canine and second premolar. Bone density will be measured using Hounsfield Units (HU).
Measurement of alveolar bone volume
时间窗: 3 months
From CBCT scans, bone volume in areas of the maxillary alveolar process between the canine and lateral incisor, and between the canine and second premolar will be measured
Measurement of bone Microstructure
时间窗: 3 months
Using the collected CBCT scans, the region of interest will be selected within the maxillary alveolar process, and fractal dimension analysis will be performed using a special software.
