title: A transymphyseal X-ray projection to assess the anterior edentulous mandible prior to implant placement.
abstract: The provision of an implant-retained overdenture with two implants in the canine regions is a well established treatment modality. Assessment of the form of the anterior mandible is essential in order to avoid surgical complications. Cross-sectional imaging gives ideal images but has radiation and economic costs. A panoramic radiograph supplemented by a lateral cephalometric radiograph is commonly used in these cases, but the latter is not widely available in dental practices. A transymphyseal radiographic technique is presented, using equipment and materials readily available in general dental practice, which may be used as an alternative to the lateral cephalometric radiograph.
