Objectives: The clinical success of orthodontic miniplates depends on the stability of the miniscrews used for fixation. For good stability, it is essential that the application site provides enough bone of good quality. This study was performed to analyze the amount of bone available for orthodontic miniplates in the zygomatic process of the maxilla.

This study was conducted to assess the condition of bone before cortically implanting miniplates in that area of the maxilla.
Patients And Methods: A total of 51 thin-sliced computed tomography scans of 51 fully-dentate adult patients (mean age 24.
Article Synopsis
- The success of orthodontic anchorage plates relies on the stability of miniscrews, which requires good quality and quantity of bone at the application site.
- A study analyzed CT scans of 51 fully dentate patients to measure the cortical thickness of the mandibular jawbone in different anterior locations.
- Results showed that the cortical thickness is thinnest at the incisor region but increases toward the basal and distal areas, indicating that positioning the anchorage plates lower can enhance stability due to greater bone thickness.

Objective: The aim of this study was to determine the geometric accuracy of scans obtained with a newly developed cone-beam computed tomography (CBCT) device in comparison with a multidetector row computed tomography (MDCT) scanner.
Study Design: Cone-beam scans were obtained with the preretail version of a newly developed compact size device with a scan volume of 15 x 15 x 15 cm. Conventional CT scans for comparison were performed with a 6-detector row CT scanner.
