Abstract

Placement of infra-zygomatic crest screw (IZC) in patients with missing posterior teeth or low set sinus floor often presents as a clinical challenge. The ideal position of the bone screw was identified using the CBCT images. The critical factors in placement position like the available bone thickness, proximity of sinus floor and adjacent root structures were evaluated. The 3D printed guide makes the insertion of the bone screw easier and more precise. A detailed protocol for designing and printing the implant guide along with additional features for enhancing the accuracy of placemnt has been elaborated in this article.
