ProsthodonticsSelective grinding is a technique used to adjust the occlusion of complete dentures. It is best performed after the dentures have been processed and rearticulated with a new series of jaw relations to ensure that the occlusion is accurate and reflects the patient's current jaw relationship. This allows for more precise adjustments to be made, as the original records may not accurately represent the current occlusal relationship after processing.
