Class I. doesn’t mean that the denture is perfect (crowding, diasthema,
ectopic teeth, rotated teeth, impaction etc.)
![Page 17: Outline - Semmelweis Egyetem](https://reader030.vdocument.in/reader030/viewer/2022012506/6181bc3306d2917b961639e8/html5/thumbnails/17.jpg)

Angle II/1
Overjet
Distocclusion The mandible is usually behind
Sometimes the prognathism of the
upper jaw is also responsible for the
amomaly

Often acquired anomalies
(bad habit, tongue)

CLASS III MALOCCLUSION
Real III. class: macrogenia or
anterior position of the mandible
ANTERIOR CROSSBITE
Pseudoprogeny: when the
maxilla is responsible for
the anomaly (micrognathia)
or early contact of the cups
forses the mandible
forward
![Page 24: Outline - Semmelweis Egyetem](https://reader030.vdocument.in/reader030/viewer/2022012506/6181bc3306d2917b961639e8/html5/thumbnails/24.jpg)
The six keys of occlusion
(by Andrews) are:
Molar inter-arch relationship
Mesio-distal crown angulation
Labio-lingual crown inclination
Absence of rotation
Tight contacts
No (or mild) curve of Spee
![Page 25: Outline - Semmelweis Egyetem](https://reader030.vdocument.in/reader030/viewer/2022012506/6181bc3306d2917b961639e8/html5/thumbnails/25.jpg)
Angle subdivion - if the occlusion
on the right side and left side are
different
By narrowing of the arches
the lateral cusps forces the
mandible to lateral direction
Sceletal assimetry

Place analysis
The lower jaw is more important, because
we are not able to increase the size of the
mandible !!!
![Page 42: Outline - Semmelweis Egyetem](https://reader030.vdocument.in/reader030/viewer/2022012506/6181bc3306d2917b961639e8/html5/thumbnails/42.jpg)
By space analysis we compare the necessary (calculated) place with the
actual (available) place in the denture.
![Page 43: Outline - Semmelweis Egyetem](https://reader030.vdocument.in/reader030/viewer/2022012506/6181bc3306d2917b961639e8/html5/thumbnails/43.jpg)

Factors which influence the space analysis
Straightening Curve of Spee needs 0,5 – 3 mm
![Page 46: Outline - Semmelweis Egyetem](https://reader030.vdocument.in/reader030/viewer/2022012506/6181bc3306d2917b961639e8/html5/thumbnails/46.jpg)
.
Factors which influence the space analysis
Position of thef incisors
Position of the incisors
If 1 mm protrusion is possible it means 2mm place-winning
If 1 mm retrusion is necessary it means 2mm loss of place.
![Page 47: Outline - Semmelweis Egyetem](https://reader030.vdocument.in/reader030/viewer/2022012506/6181bc3306d2917b961639e8/html5/thumbnails/47.jpg)
