Alveolar Bone Loss Clinical Trial
Official title:
Accuracy of Completely Versus Partially Limiting Computer Guided Zygomatic Implant Placement. A Randomized Controlled Study
The aim of study is evaluation of accuracy of completely versus partially limiting computer generated surgical three-dimensional guides during placement of zygoma implants in patients with atrophic maxillae.
