Processing changes in complete dentures: Posterior tooth contacts and pin opening

Abstract Dentures were constructed for 50 patients. The centric relation contacts were marked and photographed before removing the finished trial dentures from the articulator and again on the same articulator and same stone mountings after processing. The amount of incisal pin opening was measured and recorded after processing. An attempt was made to analyze the patterns of centric relation contacts after processing and to determine if there was a correlation of pin opening and tooth contacts. It was found that there was a definite shift of the tooth contacts to the more posterior teeth after processing but that the amount of pin opening did not seem to be related to the number or location of the tooth contacts. The magnitude of pin opening seems to depend upon the amount of shift rather than the direction.

Single complete dentures

Abstract The development of a harmonious occlusion is most critical to the success of a single complete denture treatment. Achieving this desirable characteristic is usually much more difficult than arranging artificial teeth for opposing complete dentures. Various oral situations were discussed in which single complete dentures are indicated, and a clinical procedure for treating patients who are edentulous in one arch are described.

Denture modification during adjustment phase of complete denture service.

Abstract Records were kept on the adjustment phases of treating 64 patients with new complete dentures. Five dentists treated the patients independently of each other. All dental laboratory procedures were performed by the same dental laboratory technician under the same conditions.
