face bow
Very low / TechnicalHighly technical/Professional
Definition
Meaning
A thin, flexible bow-shaped instrument used in dentistry and prosthodontics to record the spatial relationship between the maxilla (upper jaw) and a reference point (like the temporomandibular joint).
A dental device for transferring the positional relationship of the jaws to an articulator (a mechanical instrument that simulates jaw movements), crucial for creating accurate dental restorations, dentures, or orthodontic appliances.
Linguistics
Semantic Notes
This is a compound noun with a highly specific, technical meaning. It is not related to archery. 'Face' refers to the patient's face/head, and 'bow' describes its curved, bow-like shape. Understanding requires domain knowledge (dentistry).

FAQ
Frequently Asked Questions
No, it is a non-invasive measuring device. It is placed lightly against the face and inside the mouth briefly. It may feel unusual but is not painful.
Yes, for single crowns or simple restorations, a face bow is often not used. It is most critical for complex rehabilitations, full dentures, or when precise occlusal harmony is essential.
A bite registration records how the upper and lower teeth fit together. A face bow records how the upper jaw relates to the skull's hinge axis (jaw joints). They are often used together.
It rhymes with 'go' (/boʊ/). It refers to the curved, bow-shaped instrument, not the act of bending forward.
