Question 232 (part 2) · LDEK · Dental laboratory technology
The extent of alveolar process reduction on plaster model depends on the periodontium condition in the area of extracted teeth.

It is a method develped by:

- B. Reichenbach.
- C. Płonka.
- D. Campagna.
- E. Firtell.

Recall the cast reduction method used when teeth are extracted for periapical rather than periodontal reasons.
