[Investigation of the relationship between the posterior edge of the base of complete lower dentures and the mandibular tuberculum].

Surveying the data published in the literature one can establish that opinions of authors differ concerning the appropriate relationship between complete lower dentures and the tuberculum alveolare mandibulae (TAM). Some authors claim that, following extensional principles, the base of complete lower dentures must fully cover the TAM. Others think that it is enough if the base covers half of the TAM; yet others recommend that the base should merely extend as far as the mesial edge of the TAM.

[Cantilever bridges--a cross-sectional study].

Life expectancy and functional performance of the cantilever bridges is determined by the length of the cantilever pontic(s) and by the number and localisation of the abutment teeth. No overall epidemiological survey covering this topic was found in the literature. 529 distally cantilevered bridges were evaluated by the authors.

[The dental status of elderly people in Hungary--based on mass screening].

Twenty-three % of the Hungarian population was older than 60 years at the time of this epidemiological survey. This ratio increases gradually. So it is important to know the dental status of this population both from a professional and national health service point of view.

[Study of the relationship of the mandibular alveolar tuberculum to the occlusal plane at complete lower dentures].

The distance between occlusal plane and alveolar crest has an influence on the stability of the lower denture. From the relationship of the occlusal plane to the tuberculum alveolare mandibulae we can conclude on the distance between the occlusal surface of the denture's molars and the alveolar crest. The relationship of the occlusal plane to the tuberculum alveolare mandibulae was examined in 688 patients with complete lower and upper dentures.

[Evaluation of the survival time of complete dentures with a mathematical method].

Based on the number of previous dentures and on the information given by the patients the authors describes a mathematical model for the estimation of the denture survival time. The distribution of edentulousness according to age (based on 9991 patients) shows a regular pattern and can be described by a second degree function. The survival time shows a similar regularity.
