Abstract
At present when working with dental implant we diagnose the cases in a variety of ways:oral inspection, palpation, study model, dental radiography and panoral radiography. However each of these diagnoses is not definite, still being objective and total technique, so at present, dentists have to rely on their intuition.
We have been trying to use X-ray CT with the ways mentioned above for several years in order to make diagnoses more reliable and objective.
That is, using X-ray CT, we can find the exact measurement for the highness, width density of jaw bones, and the shapes, locations and distances of maxillary sinus, incisive foramen, anterior nasal spine, nasal cavity, zygomatic arch, maxillary tuberosity, inferior alveolar canal, mental foramen, and soon which are in need of implant.
Moreover we could get a three dimensional analysis from the reconstruction of the portraits.
The method of using X-ray CT with dental implant were first introduced in Japan by Matsuzawa,Nakazima and others at the 16th meeting of the Japan Dental Implant Society.
We would like to report that our method has been effective although we need to conduct more examinations.
