Mandibola vs. mascella
In Italian, both mandibola and mascella translate to jaw, but they are not interchangeable. The main difference lies in their level of anatomical precision and common usage, with mandibola being a specific, technical term and mascella being a more general, everyday word.
Mandibola
C1This is the precise, anatomical term for the lower jawbone. It refers specifically to the single, movable bone that forms the lower part of the skull and holds the lower teeth. Think of it as the direct equivalent of the English medical term mandible. It is most often used in scientific, medical, or dental contexts.
Il paziente ha riportato una frattura alla mandibola in seguito all'incidente.
(The patient suffered a fracture of the mandible following the accident.)
L'articolazione temporo-mandibolare connette la mandibola al cranio.
(The temporomandibular joint connects the mandible to the skull.)
Il dentista ha controllato l'allineamento della mandibola.
(The dentist checked the alignment of the lower jaw.)
Nei reperti fossili, la mandibola era eccezionalmente ben conservata.
(In the fossil remains, the mandible was exceptionally well preserved.)
La mandibola si muove quando parliamo o mastichiamo.
(The lower jaw moves when we talk or chew.)
Mascella
A2This is the common, everyday word for jaw. It can be used more broadly to refer to the entire jaw area, encompassing both the upper and lower jawbones. In anatomical terms, it can also refer specifically to the upper, fixed jawbone (the maxilla). You would use mascella in most non-technical, daily conversations.
Ho un forte dolore alla mascella da questa mattina.
(I have a strong pain in my jaw this morning.)
Quell'attore è famoso per la sua mascella squadrata.
(That actor is famous for his square jawline.)
Mi è quasi caduta la mascella quando ho sentito la notizia.
(My jaw almost dropped when I heard the news.)
Sento la mascella fare 'clic' ogni volta che sbadiglio.
(I feel my jaw click every time I yawn.)

(Clenching your jaw at night can cause headaches.)
Ha ricevuto un pugno dritto sulla mascella.
(He received a punch straight to the jaw.)
Summary
In summary, the key difference is specificity and context. Use mandibola when referring specifically and technically to the lower, movable jawbone (the mandible), especially in a medical or scientific setting. Use mascella in everyday language to refer to the jaw in general, a person's jawline, or sometimes specifically the upper jawbone (the maxilla). A simple rule of thumb: if you would say jaw in casual conversation, use mascella; if a doctor is pointing to the lower jawbone on an X-ray, they would call it the mandibola.
