概要	Orthodontic cephalometry is a standardized radiographic technique that produces a lateral or postero-anterior skull radiograph from a fixed source-to-film distance and patient position. Introduced by Benjamin Broadbent in 1931, cephalometric analysis enables systematic measurement of skeletal and dental relationships to assess malocclusion, plan treatment, and monitor growth and treatment changes. The technique remains fundamental to orthodontic diagnosis and treatment planning.	Temporomandibular Joint (TMJ) analysis is a systematic clinical assessment and imaging evaluation of the jaw joint, including the articular disc, condyle, and associated musculature. TMJ analysis evaluates joint function, detects dysfunction (TMD), and guides diagnosis and treatment planning for jaw pain, clicking, locking, and limited opening. Comprehensive assessment integrates clinical examination with imaging (magnetic resonance imaging, cone-beam computed tomography) to characterize joint status and tailor treatment.
