The cast aluminum denture base. Part II: Technique.

A technique to wax-up and cast an aluminum base and a method to incorporate the base into the final denture base has been discussed. This technique does not use induction casting, rather it uses two casting ovens and a centrifugal casting machine.

Repair of broken dentures in resin undercuts.

This technique utilizes both irreversible hydrocolloid impression material and fast-setting stone to repair a denture which has fractured in a tissue undercut. This procedure maintains the same tissue surface detail on the repaired denture as existed on the denture prior to the repair.

Accurate mounting casts for complete dentures.

An accurate and efficient method to fabricate mounting casts for complete dentures has been presented. Well-made mounting casts are required to accurately transfer the jaw relation records made in the mouth to an articulator.

The cast aluminum denture base. Part I: Rationale.

Experiments with various casting techniques have been done, and aluminum base dentures have been made for many patients. The subjective clinical response from patients wearing aluminum dentures has not been different from patients wearing acrylic resin dentures. However, Brudvik and Holt have stated that they have had marked clinical success in using aluminum bases. A literature review on using aluminum as a denture base material has been presented, and the rationale for its use has been discussed. In part II, a technique will be described that can be used for casting aluminum denture bases.

Fabrication of a maxillary complete denture utilizing the neuromuscular or centric occlusion position.

The patient was unable to wear a maxillary complete denture that had been made from a verifiable record in the centric jaw relation position or terminal hinge position. When she brought her teeth together, only a few touched. Clinical examination showed that this patient had a discrepancy of approximately 3 mm anteroposteriorly and a discrepancy of 1 mm mediolaterally between the terminal hinge position and the centric occlusion or neuromuscular position. A new denture was made for the patient. The neuromuscular position was used as the starting position and as the position of maximum intercuspation (centric occlusion), and the terminal hinge position was used as a mounted border position of reference for occlusal adjustment and equilibration.
