Achieving balanced occlusion after a change in condylar guidance often requires adjustments to the dental occlusion to ensure that the teeth interdigitate properly during various movements. When the condylar guidance angle changes, it affects how the articular eminence influences the movement of the mandible, and thus, how the occlusal surfaces of the teeth contact during function.

Increasing the compensation curve, also known as the curvature of Wilson or Curve of Spee, allows for adjustments that accommodate the altered condylar guidance. The compensation curve aids in facilitating harmonious movements during lateral and protrusive excursions. It helps to distribute occlusal contacts over a larger area and minimizes interferences and discomfort during function. This adjustment can effectively realign the occlusion to maintain balanced relationships between the upper and lower teeth across various jaw movements.

Adjustments such as decreasing incisal guidance, reducing cusp height, or adding interocclusal records do not address the primary need for adapting to the changes from condylar guidance directly. Reducing cusp height might lead to less stability and support during functional movements. Decreasing incisal guidance could limit the ability to accommodate movements, which could lead to a non-balanced occlusion. Adding more interocclusal records may provide
