[Study of the relationship of the mandibular alveolar tuberculum to the occlusal plane at complete lower dentures]. / A tuberculum alveolare mandibulae és a rágósík viszonyának vizsgálata teljes alsó lemezes fogpótlásokon.

ABSTRACT

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. Results have shown, that in 30.25% the occlusal plane of the lower dentures was at higher level, than the highest point of the tuberculum alveolare mandibulae, in 41.3% it was at the level of the highest point of the tuberculum alveolare mandibulae and in 28.45% it crossed the tuberculum below its highest point. From our results the conclusion can be drawn, that in most of the cases no attention to the tuberculum line, has been paid the interalveolar distance and the occlusal plane of the natural teeth at the set-up of the molars, so this has a negative effect in 69.5% of the examined cases on the stability of the lower complete dentures.
