[Templates as an aid in implantology]

The number, position and angulation of implants are of major importance in loading of implants and surrounding bone and in esthetics. Especially in single tooth and partially edentulous cases correct positioning of implants takes a great deal of care. A template is a device that helps to achieve the proper amount of bone and the correct position and angulation of implants. The design and fabrication of radiographic templates, diagnostic templates and surgical templates are described, both in general and specifically for overdentures and non-removable implant-supported restorations.
