TSALD is a term some dental teams use as shorthand for a tooth-colored, adhesive, light-cured restorative material placed in small amounts. It is most commonly discussed in the context of minor repairs, small cavities, or as a thin “liner” layer under another filling material. The exact meaning of TSALD can vary by clinician, region, and manufacturer terminology. In everyday patient language, it generally refers to a tooth-colored resin material that bonds to teeth and hardens with a curing light.

tooth size discrepancy is a mismatch between the widths of upper and lower teeth. It describes whether teeth are proportionally “too large” in one arch compared with the other. It is most commonly discussed in orthodontics and smile design during treatment planning. It helps explain spacing, crowding, and why a bite may not “fit” ideally even when teeth look straight.

bolton analysis is a tooth-size measurement method used to compare the width of upper teeth to lower teeth. It helps identify a “tooth size discrepancy,” meaning the teeth in one arch are proportionally larger or smaller than the other. It is most commonly used in orthodontics (braces and aligners) and smile planning when spaces, crowding, or bite fit seem inconsistent. The results are usually expressed as ratios for the front teeth and for the full set of teeth used in the analysis.

digital models are computerized 3D representations of teeth, gums, and bite relationships. They are usually created from intraoral scans, desktop scans of impressions, or cone-beam CT (CBCT) data. Clinicians use them to plan treatment, design restorations, and communicate with dental labs. They can replace or supplement traditional plaster “stone” models in many workflows.

An intraoral scan (ortho) is a digital way to capture the shape of teeth and gums using a handheld camera-like scanner. It creates a 3D model that can replace many traditional “impressions” made with dental putty. It is commonly used in orthodontics for clear aligners, braces planning, retainers, and tracking tooth movement over time. The scan is stored as a digital file that can be used for planning and fabrication.

CBCT stands for cone beam computed tomography, a 3D dental imaging scan. It uses a cone-shaped X‑ray beam to capture many images and reconstruct a three-dimensional view. CBCT is commonly used in dentistry and oral surgery for detailed evaluation of teeth, jaws, and surrounding structures. It is different from a standard dental X‑ray, which is typically two-dimensional.

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**.
