Selecting The Right Dental Articulator
A Guide for Indian Practices

While these instruments are robust, it's good practice to check for wear and tear annually. Verify the incisal pin is at zero and that there is no lateral play in the condylar elements. A full manufacturer calibration is recommended every 3-5 years, especially for devices used in high-volume labs or practices to maintain accuracy.

For a single posterior crown where the occlusion is well-established and supported by adjacent teeth, a facebow may not be strictly necessary. However, for any anterior crown, bridge, or case involving multiple units, a facebow transfer is critical. It provides an essential baseline that saves significant chair time by reducing occlusal adjustments by up to 80%.

The primary advantage is precision. A fully adjustable system can be programmed to replicate the patient's exact condylar border movements, including the precise curvature of the condylar path and the immediate and progressive side shift. This level of detail is impossible with a semi-adjustable model's average settings and is essential for success in full mouth rehabilitation cases with 10 or more units.

Using a simple hinge for complete dentures is strongly discouraged. It cannot replicate the protrusive or lateral movements necessary to create a balanced occlusion. This will result in denture instability, poor function, and patient discomfort. At minimum, a semi-adjustable (Class III) instrument is required to set denture teeth for proper function, with an average setting of 30 degrees for the condylar guidance.
