Application of CT imaging for dental implant simulation.

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/Plant) 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/Plant for simulation of various examinations and diagnosis incorporating CT information are described, and their features are introduced.
