Monoplane occlusion (non-anatomic teeth)

By Dr. Vishaal Bhat on Sunday, July 6, 2008 with 0 comments

Can have balanced and non-balanced occlusion with non-anatomic teeth.

Jones took DeVan’s principles and added vertical overlap for esthetics:

The principles:

-0º condylar guidance

-0º incisal guidance

-0º cusp height

-flat occlusal plane

-no vertical overlap (Jones) / vertical overlap (DeVan)

7 advantages of monoplane occlusion:

1. More adaptable to unusual jaw relations

2. Can be used in cross-bite cases

3. The mand does not get locked into one position

4. Greater comfort and efficiency

5. Improved denture stability

6. Accommodates to changes in horizontal and vertical relations

7. Relining and rebasing are easier

5 disadvantages to monoplane occlusion:

1. Less efficient mastication

2. Esthetically inferior

3. Clogging of occlusal surfaces

4. Poor food penetration

5. Difficult to establish balanced occlusion

5 indications for monoplane occlusion:

1. Class II or III malocclusion

2. Severe residual ridge resorption

3. Excessive interarch distance

4. Poor neuromuscular skills

5. Poor patient adaptability
