Introduction:
Implant planning and placement in the fully edentulous maxilla can present challenges both surgically and prosthetically whether a removable or fixed approach is planned. Placement of the implants free-hand does not take the osseous anatomy and its structures into consideration and may lead to problems such as nerve or blood vessel impingement as well as implant extension into sinuses or the nasal fossa. Guided placement has become the standard practice whether treating the full arch or partially edentulous arch. While printed surgical guides are the standard practice, There may be circumstances where printed guide is not possible.
