Abstract

Sucking forces

- Compared with the normal primary impression techniques, in primary impression techniques sucking forces of maxilla increases: 0,094 ± 0,054 g, for mandible: 0,082 ± 0,047 g on average.

- Compared with the second non-marginal impression techniques, sucking force of the second marginal increases: 0,190 ± 0,179 g for maxilla, and 0,136 ± 0,072 g for mandible.

Dentures: 100% maxilla is fitted after using marginal impression techniques.

87% mandible is fitted after using marginal impression techniques.

Application of Quick Axis: Add teeth on parameter would demonstrate quite comprehensively the condyle information and occlusion, and Quick Axis is also used to determine Bennett angle and slope of condylar orbit of mandibular joint to program the overdentures which help the thesis be more clinically meaningful.
