[The role of guide planes in the retention of removable partial dentures].

Modern understanding of the retention mechanism of partial denture assumes that the path of insertion and the path of displacement of denture form a definite angle. The denture is possible to insert in a given direction only after forming guide planes which, in the same time, possible take part in retention of denture. The aim of this work was to test the hypothesis that the preparation of guide planes and bending of models in the surveyor brings, the rigid parts of framework to increase the ability of denture to be kept on supporting tissue. The research was performed on the frameworks of denture which were of same design and models with and without preparation guide planes. Total of 60 framework removings from the vertical direction were made under the different conditions of the measurement, using universal electronic machines.

[Anatomical and histological characteristics of proximal surfaces of abutment teeth].

When the guide planes are formed on the proximal surfaces of abutment teeth the part of enamel is removed. Thickness of enamel and inclination of tooth are the factors that limit the possible tooth reduction. In this report anatomical and histological characteristics of proximal surfaces of the abutment teeth are analysed. Thickness of the enamel has been measured using the optical microscope for 280 prepared teeth. Measurements were performed on four zones of tooth's proximal surfaces, on the different distances from the top of enamel edge. Undercut of 420 proximal surfaces of tooth have been determined by micro-analyser with accuracy of 0.05 mm. By comparing the mean values of enamel thickness, in occlusal thirds, and undercut of proximal surfaces, it is possible to conclude that the formed guide plane remains in the enamel even after the removing of all natural undercuts.

[The influence of different conditions of refractory mold preparation on precision of casting of Co, Cr, Mo alloys].

The following hypothesis was made: different conditions of preparation and heat treatment of refractory mold change its physical and mechanical characteristics which is of great importance for the precision of casting of Co, Cr, Mo alloys. To prove this hypothesis measurements of setting time, setting and thermal expansion and transverse strength were performed regarding the relationship between the powder and the liquid of investment. The research was carried out on "Politerm C", "Rema Exakt" and "Widerit" investments. The obtained results proved the hypothesis that different conditions during the preparation of refractory mold had a certain influence on the quality of casting of Co, Cr, Mo alloys. The domestic investment was approximately of the same quality as the tested investments of foreign origin.

[Application of surveyor in designing partial denture. 4. Partial denture designing and preparation of master model for duplication in surveyor].

The article "Partial denture designing and preparation of master model for duplication in surveyor" is the last of four articles from a series which deals with application of surveyor in designing partial denture. The aim of this article is to describe partial denture designed as "step by step method". The operation with the surveyor, which supposes obligatory analysis of stady casts in order to prepare the supporting tissues, determination of the optimal part of denture insertion and finding of 2 heights of contour, gives this concept a biological character. Such designed partial dentures meet the prophylaxis requirements and have desired retention; they are comfortable and look well. As the suggested concept of partial denture design in surveyor represents the present achievements, in the conclusion of this paper its obligatory application is suggested.

[Application of surveyor in designing partial denture. 3. Analysis of the study cast in surveyor].

The widely accepted method in partially edentulous treatment plan is the analysis of study cast. In our practice, however, various excuses are enumerated in order to avoid this method. The aim of this paper is to describe stages of the analysis of study cast in surveyor and to emphasize advantages of this therapy. Study cast analysis enables a real view of occlusion, morphological characteristics of abutment teeth and presents information about possible metal framework design. The conclusion of this paper is that the analysis of study cast could be an obligatory stage in preparing a patient partially edentulous treatment.
