Articulators and Facebow: A Comprehensive Guide to Components, Classification, and Clinical Use
Articulators and facebows are foundational instruments in prosthodontics, restorative dentistry, and dental laboratory work. Understanding their design, components, and clinical purpose is essential for every dental student and practitioner. These devices allow dental casts to be mounted and manipulated outside the mouth in a way that simulates — to varying degrees — the movements of the patient's temporomandibular joints and mandible, enabling accurate diagnosis, treatment planning, and fabrication of prosthetic restorations. This article provides a structured, didactic overview of the main types of articulators — from simple hinge devices to fully adjustable gnathological instruments such as the Gerber articulator — and the facebow system, including its components and the Fox occlusal plane indicator (Fox fork). Each instrument's key anatomical parts, clinical indications, and limitations are explained with comparison tables to support student learning. The article also introduces the emerging role of virtual articulators in digital dental workflows.
