OPG Dental X-Rays: Precision Panoramic Imaging for Better Diagnosis

An OPG (orthopantomogram) is one of the most valuable tools in modern dental imaging, providing a comprehensive view of both jaws, all teeth, and the surrounding bone structures in a single scan.
At 3Beam Imaging Centre in Harley Street, we perform digital OPG dental X-rays using high-resolution panoramic systems that combine diagnostic precision with minimal radiation dose — ideal for both general dentistry and specialist maxillofacial assessment.

How an OPG X-Ray Works

Unlike intraoral X-rays that capture small, localised areas, an OPG X-ray uses a rotating arm that moves around the patient’s head, projecting a narrow beam in an arc.
As the sensor and X-ray source move synchronously, a panoramic reconstruction is generated — visualising the teeth, mandible, maxilla, temporomandibular joints (TMJs), and sinus outlines in a single image.

Modern OPG systems at 3Beam employ digital detectors rather than film, providing sharper contrast, faster acquisition, and dose efficiency compliant with IR(ME)R and SEDENTEXCT guidelines.

Clinical Applications of an OPG Dental Scan

An OPG is not simply a “routine dental X-ray” — it serves multiple diagnostic and treatment-planning purposes across dental disciplines:

1. Oral Surgery and Implants

• Pre-operative bone assessment before implant placement

• Visualisation of anatomical landmarks such as the inferior alveolar canal

• Screening for retained roots, cysts, or impacted teeth

2. Orthodontics and Growth Assessment

• Evaluation of dental eruption patterns and spacing

• Assessment of skeletal asymmetry and jaw relationship

• Baseline imaging before cephalometric or CBCT evaluation

3. Endodontics and Restorative Dentistry

• Identification of periapical lesions, large carious defects, or residual infection

• Detection of previously undiagnosed pathology affecting treatment outcomes

4. Maxillofacial and TMJ Evaluation

• Assessment of temporomandibular joint morphology

• Screening for fractures, condylar resorption, or degenerative changes
