Accurate presurgical determination for implant placement by using computerized tomography scan.

A template is often used for the presurgical planning of implant placement. However, a major drawback is that the CT image of the radiopaque marker is not often clear. This article describes a method of fabricating a template with a stainless steel tube sprue for accurate radiographic evaluation and implant placement. Stainless steel tube sprues are inexpensive, indicate the eventual implant inclination, and facilitate precise placement, from the CT scan without any interference from scattered radiation.
