Sem 8: Tooth notation and missing teeth

Flashcards covering tooth notation and classifications of missing teeth.

Zsigmondi System

A system for marking teeth using a cross to divide the dental arches into quadrants, with permanent teeth numbered 1-8 and milk teeth numbered I-V (later changed to letters A-E by Palmer).

Haderup Notation

A tooth notation method that uses a plus sign (+) for the upper arch and a minus sign (-) for the lower jaw, placed before or after the tooth number to indicate the side.

Allerhand Correction

A correction to the Haderup notation that changes the numbers of primary teeth to consecutive Roman numerals.

Universal Numbering System

A tooth numbering system where milk teeth are described using capital letters A-T, and permanent teeth are numbered 1-32.

Viohl System (FDI)

A two-digit system where the first digit indicates the quadrant and the second digit corresponds to the order of the tooth in the dental arch.

Galasińska-Landsberger Classification

A classification system for missing teeth that divides them into 5 classes and is widely used in Poland.

Eichner Classification

A classification system that takes into account the occlusal conditions of the dental system and includes 3 groups (A, B, C) with subgroups, based on support zones.

Support Zones

Groups of opposing teeth in the maxilla and mandible (molar and premolar teeth on both sides) that determine correct occlusion height and mandibular position.

Eichner Classification - Group A

Contacts between opposing teeth exist in all support zones; may include a full set of teeth, teeth damaged but rebuilt, or deficiencies in both arches but with supports in all zones.

Eichner Classification - Group B

Opposing contacts between teeth are not present in all support zones; may have contacts in three, two, or one support zone, or outside the support zones.

Eichner Classification - Group C

No contact between the opposing upper and lower teeth; may include residual dentition of the maxilla and mandible without mutual contact, teeth only in one arch, or edentulous cases.
