Using computer-guided surgery for partial guidance of zygoma implants.

Patients with advanced atrophy of the maxilla benefit greatly from the use of dental implants. In the past, protocols recommended highly invasive bone grafting, which required months of maturation before implant placement. Over the past decade, zygoma implants have been used as an alternative procedure. While computer-guided surgery provides a great benefit, its use for complete placement of zygoma implants is not yet predictable. The following protocol provides a way to facilitate the placement of zygoma implants into the best position surgically and prosthetically using partially computer-guided surgery.
