Accuracy of drilling guides for transfer from three-dimensional CT-based planning to placement of zygoma implants in human cadavers.

The accuracy of surgical drilling guides was assessed for placement of zygoma implants. Six zygoma fixtures of length 45 mm (Nobel Biocare, Göteborg, Sweden) were placed in three formalin-fixed human cadavers using surgical drilling guides. The fabrication of these custom-made drilling guides was based on three-dimensional computerized tomography (3D-CT) data for the maxillary-zygomatic complex.

Imaging technique selection for the preoperative planning of oral implants: a review of the literature.

Background: As the use of oral implants for the treatment of partially as well as fully edentulous patients has increased the past two decades, more specialized radiographic techniques have become available for the preoperative planning of oral implant placement.

Purpose: The goal of this article was to enable clinicians to select the appropriate imaging techniques when planning for oral implants.

Materials And Methods: This artide reviews the available literature about various imaging techniques and their indication for the preoperative planning of oral implants.
