Sažetak
Many techniques have been used for measurement of vertical relation in edentulous patients. The aim was to test the influence of changed head position on interocclusal space when the vertical dimension was determined by fonetic methods (“s” and “mi”) or by the method of determining physiological rest position dependent on the patient’s physionomy and masticatory muscle relaxation.
This study included 62 fully dentulous subjects of Angle Class I. They were instructed to say “s”, and “mi”, and to maintain mandibular postural rest position until the freeway space was measured. This was done in three different head positions: straight, head leaned back and head leaned forward. Freeway space was measured with a precise calliper, modified for intraoral measurement.
There was no significant difference between gender (p > 0.05). The results showed that head position has an important impact on the size of freeway space in the postural rest position (p < 0.01), while during speach of “s” and “mi” the size of freeway space remained constant (p > 0.05).
The results confirm that determination of the vertical relation should include phonetic methods rather than physionomy method alone.
