2. Refining your Denture Setups After try in of the trial denture, the denture setup must be refined so that minor discrepancies in occlusal plane, centric and bilateral balance etc., are corrected. The purpose of this section is to review the appropriate methods of refining your denture setups prior to processing.

4. Check to see that the marks made previously on the casts indicating midline, crest of the ridge, and the retromolar pad are still present . These landmarks will be used to refine your denture setup. Maxilla Midline Anterior land Mandible Ridge Retromolar pad Refining your Denture Setup

5. Lingualized Occlusion

6. Refining your Denture Setup Position the appropriate protrusive insert, and check to ensure that the incisal guide pin is set at zero and in contact with the incisal guide table. Lingualized occlusion

7. Lingualized Occlusion Anterior teeth The position of the maxillary anterior teeth were established at try in. Note that the maxillary anterior teeth follow the curvature of the arch.

9. Lingualized Occlusion Ensure that the denture teeth are on plane. The plane of occlusion should be parallel to the body of the mandible and extends from the incisal edges of the central incisors and the middle portion of the retromolar pads bilaterally. The appropriate Curve of Spee should be incorporated into the setup.

11. Verify centric and make adjustments as necessary. The lingual cusps of the maxillary posterior teeth must rest in the central fossa of the opposing mandibular teeth. There should be no buccal cusp contacts of posterior teeth in centric or in lateral excursion. Lingualized Occlusion

16. Monoplane Occlusion

17. Refining your Denture Setup Position the appropriate protrusive insert, and check to ensure that the incisal guide pin is set at zero and in contact with the incisal guide table. Monoplane occlusion

18. Monoplane Occlusion Anterior teeth The position of the maxillary anterior teeth were established at try in. Note that the maxillary anterior teeth follow the curvature of the arch.

26. Lingualized Opposing Monoplane

28. Lingualized Opposing Monoplane Anterior teeth The position of the maxillary anterior teeth were established at try in. Note that the maxillary anterior teeth follow the curvature of the arch.

38. Refining your Denture Setup Position the appropriate protrusive insert, and check to ensure that the incisal guide pin is set at zero and in contact with the incisal guide table. Semi-anatomic

39. Refining your Semi-anatomic Setup Anterior teeth The position of the maxillary anterior teeth were established at try in. Note that the maxillary anterior teeth follow the curvature of the arch.

44. Refining your Anatomic Setup

45. Refining your Denture Setup Position the appropriate protrusive insert, and check to ensure that the incisal guide pin is set at zero and in contact with the incisal guide table. Anatomic occlusion

46. Refining your Anatomic Setup Anterior teeth The position of the maxillary anterior teeth were established at try in. At this stage only the central incisors need be on the occlusal plane. Note that the maxillary anterior teeth follow the curvature of the arch.

48. Refining your Anatomic Setup Verify that the posterior teeth are on plane and the posterior teeth centered over the mandibular ridge.
