[Overlay dentures].

Overlay dentures which are accepted as superposition appliances have been presented by three cases in this article. These kind of dentures are dedicated as prosthodontic restorations which are applied to extend maxillary arch horizontally in the cases of maxillary collapse. These restorations also increase the vertical dimension which has been lost and so help to improve the facial contour as well as esthetics of the individual-these dentures classified as removable partial or complete overlay dentures are generally applied in the cases of bilateral or unilateral maxillary collapse which have been caused by trauma or tumor resection.

[Investigation of the castings marginal adaptation using investment expansion methods].

The research in the field of metal casting has recorded a continual progress in dentistry. Particularly, due to the economic problems posed by the use of gold alloys relatively inexpensive metal alloys tend to gain increased popularity. Application of such alloys physically in dentistry and their adaptability to various preparations are being studied. In castings where investment expansion methods are employed, and marginal adaptability of castings are evaluated, the results of variance analysis have indicated little significant difference due to the applied methods. However, the hygroscopic method has proved highly successful in terms of marginal adaptability.

[Comparison of investment expansion methods aspect of porosity].

Currently, the use of non-precious metal alloys in fixed prosthetic restorations has warranted review of the work done sofar using precious metal alloys. One of the parameters exhibiting the success of castings done using non-precious metal alloys is porosity, which is evaluated through such methods as rod forms, waxing heat, to investing and other castability methods. The porosity ratios of cats similarly done employing different investment expansion methods have been evaluated. While there is no statistical difference due to different methods, the hygroscopic expansion method noted successful results.

[Use of endodontically treated teeth in removable partial dentures].

In our study, cases where teeth with excessive crown loss served as abutments, where examined in Kennedy Class II modification 1, that have tooth and tissue support on removable partial dentures which were constructed with the same design. Our study aims to examine, how vertically directed forces are transmitted to the supporting tissues by using photoelastic method. Teeth with case post and core appliances were used as abutments for removable partial dentures. Vertical loading procedure following the construction of removable partial dentures with the same design, revealed distribution of force over dentulous and edentulous ridge areas. When a comparison between endodontically treated and sound abutment teeth, was made, we had the conclusion that teeth with excessive crown loss can successfully serve as abutments for partial dentures, because the results of our finding exhibited no significant difference.
