title: Gelb depth gauge: a diagnostic aid in implant placement.
abstract: Case reports describe the use of a radiographic depth gauge in conjunction with computerized axial tomography. This gauge identifies for the surgeon the precise site of implant preparation that will not only be in accord with anatomic vital structures, but also achieve parallelism with adjacent teeth and other implant sites. Discrepancies in angulation can be corrected, and maximum suitable fixture length can be determined.
