COMPARATIVE REVIEW OF GNATHOMETRIC CHARACTERISTICS IN TOTAL DENTURES AND EUGNATHIC SUBJECTS

The problem of determining the position and lining of the teeth in tot al dentures is presented by a comparative examination of gnathometric variables in eugnathic subjects and in those wearing total dentures. T he material consisted of 51 plaster casts of eugnathic subjects and 49 subjects wearing total dentures. The following were examined: upper t otal number of incisors (TI), anterior width (AW), posterior width (PW ), anterior length (AL) and posterior length (PL) of models. Analysis of the investigated variables was carried out by means of sliding cali pers MECANIC Type 6901 (IVOCLAR, Lichtenstein) with a scale of 0-130 m m, and reading accuracy 97.5%. A three-dimensional pair of compasses a ccording to Korhaus (Dentaurum Germany) was used to measure the anteri or and posterior lengths of models, with a scale 10-60 mm and reading accuracy 95%. No significant difference was observed between the eugna thic subjects and subjects wearing total dentures (p > 0.05). The resu lts of this comparative gnathometric analysis of examined variables (T l, AW, PW, AL and FL) are a contribution to the rules when lining ante rior and posterior teeth in total dentures.
