Comparative review of gnathometric characteristics in total dentures and eugnathic subjects

The problem of determining the position and lining of the teeth in total dentures is presented by a comparative examination of gnathometric variables in eugnathic subjects and in those wearing total dentures. The material consisted of 51 plaster casts of eugnathic subjects and 49 subjects wearing total dentures. The following were examined: upper total number of incisors (T1), 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 calipers MECANIC Type 6901 (IVOCLAR, Lichtenstein) with a scale of 0-130 mm, and reading accuracy 97.5%. A three-dimensional pair of compasses according to Korhaus (Dentaurum, Germany) was used to measure the anterior and posterior lengths of models, with a scale 10-60 mm and reading accuracy 95%. No significant difference was observed between the eugnathic subjects and subjects wearing total dentures (p > 0.05). The results of this comparative gnathometric analysis of examined variables (Tl, AW, PW, AL and PL) are a contribution to the rules when lining anterior and posterior teeth in total dentures.
