OPG is a panoramic dental X‑ray that captures the upper and lower jaws in a single wide image. It is also commonly called a panoramic radiograph or panoramic X‑ray. OPG is widely used in general dentistry, oral surgery, orthodontics, and hospital dental settings. It helps clinicians review teeth, jawbones, and surrounding structures in one view.
A panoramic radiograph is a wide, two-dimensional dental X‑ray that captures the upper jaw, lower jaw, and surrounding structures in one image. It is commonly used in general dentistry, oral surgery, orthodontics, and pediatric dentistry for screening and treatment planning. The image is taken with a machine that rotates around the head while the patient remains still. It helps clinicians see teeth and jaw anatomy that may not fit on small, intraoral X‑rays.
IMPA is a term often used to refer to an injectable, flowable resin-based composite approach for tooth restorations. It is commonly discussed in the context of minimally invasive aesthetic dentistry and small-to-moderate repairs. In practice, IMPA may describe a material type (injectable composite) and/or a technique for placing it with a planned shape. Specific products and exact meanings can vary by clinician, region, and manufacturer.
FMA is commonly used as a shorthand term for a **flowable resin-based composite** placed in teeth. It is a **tooth-colored restorative material** that can be flowed into small or irregular areas before being hardened. FMA is most often used in **restorative dentistry** for small fillings, liners, and repairs. Meaning and exact product choice can **vary by clinician and case**.
The ANB angle is a measurement used in orthodontics to describe how the upper jaw and lower jaw relate to each other from front to back. It is calculated on a side-view skull X-ray called a lateral cephalogram. Clinicians use it as part of “cephalometric analysis,” which is a set of measurements that help with diagnosis and treatment planning. In simple terms, it helps estimate whether the jaws are well aligned, or whether one jaw sits too far forward or back relative to the other.
SNB angle is a measurement used in orthodontics and jaw (orthognathic) assessment. It describes how the lower jaw (mandible) sits front-to-back relative to the cranial base. It is measured on a lateral cephalometric radiograph (a side-view head X-ray) or its digital equivalent. Clinicians use it to help describe bite relationships and guide diagnosis and treatment planning.
SNA angle is a cephalometric measurement taken from a side-view skull X-ray (lateral cephalogram). It describes the front-to-back (sagittal) position of the upper jaw (maxilla) relative to the cranial base. Dentists and orthodontists use SNA angle as part of orthodontic diagnosis and treatment planning. It is commonly reported alongside related measurements such as SNB and ANB in cephalometric analyses.
ceph tracing is the process of drawing and measuring key anatomical landmarks on a cephalometric radiograph (a standardized side-view head X‑ray). It is commonly used in orthodontics and jaw surgery planning to analyze facial and jaw relationships. The tracing can be done by hand on an overlay or digitally using orthodontic software. The results help clinicians describe growth patterns and tooth–jaw positioning in a consistent way.
A lateral ceph is a side-view dental X‑ray of the head taken in a standardized position. It shows the relationship between the teeth, jaws, and facial bones in a single image. It is commonly used in orthodontics and jaw (orthognathic) surgery planning. Clinicians also use it to track growth and treatment changes over time.
