説明
In implant treatment, we use computed tomography (CT) with a radiographic measurement stent to decide the accurate position of fixtures preoperatively. In order to show the position and direction of fixtures on CT images, alminium pipes, which are the same in diameter as fixtures, are placed on the stent. Hydroxyapatite phantom is used for the measurement of bone mineral content.<br>This CT examination provides the following useful information:<br>1) A series of axial CT images were obtained in a short time without patient's movement. These images, 2-mm thick slices, were able to give enough information about the bucco-lingual width, shape and density of the bone.<br>2) Multiplanar reformation (MPR) images were reconstructed from a series of axial images. Alminium indicators of the stent were useful to decide the optimum position and direction of fixtures, because MPR images could show the anatomical structures where implants were to be placed.<br>3) Three-dimensional (3D) images reconstructed from a series of axial images were useful in showing the bone surface and the adjacent inclined roots.<br>4) Bone mineral content in the jaw bone was measured using hydroxyapatite phantom.
