14-year-old male presented with radiopacity near area #21-22. It was noticed by his orthodontist when starting orthodontia. It was not clear at the time of consult what the area was and if it was lying on the labial or lingual side. After using the CS 9000C 3D system, were we able to view the exact position of the supernumerary tooth.
The panoramic image has been the mainstay in imaging for OMS for decades, but it has limitations. Accurately identifying the location of superimposed objects is difficult with 2D images, but the CBCT scan makes it easy and gives pinpoint accuracy. Having exact measurements of the depth of field and having crosssectional images gives the surgeon complete confidence in the location of adjacent vital structures and adjacent teeth. The benefits of 3D imaging highlighted by this case include: 1) knowing assuredly where the supernumerary tooth was located and how much space existed between it and the adjacent teeth; and 2) knowing how much cortical bone was over the site. As a result, no intraoperative estimations were needed!
