The document describes the steps to take an accurate centric relation bite registration using the Lucia Jig. Key steps include: 1. Applying adhesive to the Lucia Jig and dispensing bite registration material into the jig. 2. Placing the jig on the upper teeth and using a Whale Tail to level and orient the jig. 3. Determining the patient's most retruded position by marking the lower incisors on the jig with articulating paper. 4. Instructing the patient to bite down firmly on the jig to seat the condyles in the proper position.
