Accurate diagnosis and exact treatment planning are very important for successful implant treatment. Pretreatment examination and simulations using CT can be especially effective information sources, and diagnosis by CT imaging before treatment substantially enhances the security and safety of the treatment plan. New interactive CT software (SIM/PlantTM) which enables diagnosis of bone morphology and quality, and also implant simulation on a personal computer through multiplanar reformation of CT images, has been developed. Stereolithography-models (SLMs) are reproduced anatomical morphological models of an individual patient's bone structure from the information obtained by the CT scan, and is fabricated out of light cure resin. In this article, SLMs and SIM/PlantTM for simulation of various examinations and diagnosis incorporating CT information are described, and their features are introduced. (J. Oral Sci. 41, 157-161, 1999)
Proper examinations before treatment are needed in any implant case regardless of the degree of difficulty. It is particularly important in difficult cases to collect as much accurate information as possible. Pretreatment examinations and simulation using CT can be very important information sources. It was emphasized that prosthodontic factors including occlusion maintenance are important for the long-term success of implants. Restorations should not be made where an implant was placed, but implants should be placed at the optimize position for the restorations. CT information is indispensable in this regard.
