Treatment planning for single tooth restorations

Question 1

Treatment planning for single tooth restorations

Answer 1

The selection of the material and design of the restoration is based on several factors
1. Destruction of tooth structure
2. Esthetics
3. Plaque control
4. Financial considerations
5. Retention

Question 2

Biological considerations

Answer 2

-Preservation of tooth structure
-Avoid overcontouring
-Supragingival margins
-Harmonious occlusion
-Protection against tooth fracture

Question 3

Mechanical considerations

Answer 3

-Retention form
-Resistance form
-Deformation

Question 4

Esthetic considerations

Answer 4

-Minimum display of metal
-Maximum thickness of porcelain
-Porcelain occlusal surfaces
-Supragingival margins

Question 5

5 principles of tooth preparation

Answer 5

1. Preservation of tooth structure
2. Retention and resistance
3. Structural durability
4. Marginal integrity

Question 6

Preservation of tooth structure

Answer 6

-Use partial coverage rather than full coverage crowns

-Prepare teeth with minimal taper

-Follow anatomical planes of the tooth to give uniform thickness of the restoration

-Prepare axial walls so that tooth structure is evenly removed and surrounding pulpal tissue is retained

-Selection of marginal geometry that is conservative and yet compatible with other principles of tooth preparation

-Avoidance of unnecessary apical extension of the preparation
