title: Parallelism of implants visualised on the orthopantomogram.
abstract: Orthopantomography is often used in implantology to determine the position of implants in the bone. Implants, which in fact are parallel, can be projected in a non-parallel position. Considerations inherent to the technique of orthopantomography are responsible for this phenomenon. In this study some experiments were carried out to demonstrate this. It can be concluded that orthopantomography cannot be used to determine whether implants are placed parallel or not.
