The mini implants, which were originally designed to fix bony segments, has shown great
promise as a simpler and more versatile solution for obtaining absolute anchorage, No Osseo
integration is required. Mini implants are placed in many anatomic sites, depending on the
indication and the biomechanics used. One of the most popular sites of placement is the buccal
cortical plate of mandible. So that this study was done to evaluate the tomographic imaging in
measuring buccal cortical bone thickness as an adjunctive radiographic technique for an
appropriate mini implants site selection. 30 patients were imaged by using a tomographic
technique from planmeca panoramic machine (planmeca Promax, Helsinki, Finland) mesial to
mandibular first molars choosing'' mixed tomo,'' ''3xCRS 1 LNG'' (3 cross sectional and 1
longitudinal) with 95s radiographic time, 1 mA and 68 kV parameters, making measurements by
using planmeca Romexis software 3.1.1.R version at four deferent levels 2,4,6,8 mm from the
alveolar crest with 0.1mm width cursor to measure the buccal cortical bone thickness prior mini
implants placement . This study was resulted in that by comparing with panoramic radiograph,
measuring cortical bone thickness, intercortical bone thickness and interradicular space using
tomographic radiograph become a more valuable wise than panoramic radiograph. In conclusion,
tomographic radiograph may acquire a new radiographic indication prior mini implants
placement for orthodontic anchorage replacing dental panoramic radiograph and periapical
radiograph.
