[Changes in shape of complete dentures in the mouth].

Form changes of complete dentures were measured in 60 patients. Some of the dentures were made of Paladon 65 and the others of PMMA by the "casting method". The first check was made on the day when the denture was inserted and the last up to 90 days thereafter. In the time the denture was worn, the form changes were recorded and evaluated by means of special markings. It was found that, under masticatory load, the dentures were slightly expanded transversally by 0.2 to 0.4% in the regions of the tuberosity and the anterior teeth. It was not possible to demonstrate a clear difference in the form stability of the base material Paladon 65 and that of PMMA (using the "casting method") during the three month in which the dentures were worn.

[Is the testing for changes in shape of denture base materials meaningful].

The results obtained in measurements of the dimensional behavior of U-shaped specimens correspond to the dimensional behavior of dentures. Part of the dimensional changes found in U-shaped specimens are not observed to the same extent in dentures, but produce interior tension in the denture. The bigger the dimensional changes in the U-shaped specimen, the bigger the dimensional changes in the denture or the tensions in its interior. Thus, the results of the measurements of U-shaped specimens demonstrate the behavior of a clinically used denture. Corresponding guidelines for testing purposes are proposed.

[Remounting of complete dentures].

A remounting method in which after polymerization, total dentures together with the original models are replaced into the articulator and are ground in there, does not produce the accuracy we are aiming at when determining the intermaxillary relation by means of registration with a central pin. On the patient it was demonstrated that grinding-in after intraoral registration of the finished mandibular and maxillary total dentures by means of the central pin registration, interlocking, and placement into the articulator produces more accurate results.

[Shape retention of plastic prostheses manufactured by the pouning method].

In investigations was shown that PMMA dentures fabricated by injection molding have a better dimensional stability than polycarbonate dentures (Andoran) and are slightly better than packed Paladon 65 dentures. When using the injection molding technique a slight increase in occlusion could not be prevented in any of the dentures.
