Which device allows the full programming of condylar paths and incisal guidance?

• A. Semi-adjustable articulator
• B. Fully adjustable articulator
• C. Digital articulator with no mechanical components
• D. Hinged, non-adjustable articulator

Answer: (B)

A fully adjustable articulator is designed to be programmed to reproduce a patient’s individual condylar paths and incisal guidance, which is essential for accurately simulating how the jaw moves during function. This type of articulator lets you set and customize the condylar inclination, Bennett movement (lateral shift), and the anterior guidance to match the patient’s actual jaw movements. With those parameters adjustable, you can faithfully reproduce the dynamics of the bite, enabling precise occlusal analysis, record transfer, and fabrication of restorations.

A semi-adjustable articulator can adjust some aspects, like the condylar guidance angle and sometimes incisal guidance, but it cannot replicate the full range of dynamic movements and lateral shifts that a patient exhibits. A hinged, non-adjustable articulator is fixed and cannot be programmed to match individual movements at all. A digital articulator with no mechanical components may still simulate movement in software, but without the full mechanical adjustment capability, it cannot guarantee the same depth of physical path reproduction as a fully adjustable device.

So, the device that allows full programming of condylar paths and incisal guidance is the fully adjustable articulator.
