Tooth Preparation
Tooth Preparation
The process of shaping the tooth to accommodate a restoration, preserving tooth structure as much as possible.
Conservative Tooth Preparation
Conservative Tooth Preparation
A dental restoration technique focused on minimizing tooth removal and promoting maximum preservation of tooth structure.
Retention
Retention
A critical factor in the longevity of dental restorations. It ensures the restoration stays in place.
Resistance Form
Resistance Form
A key principle aimed at preventing the restoration from breaking under chewing forces.

Principles of Tooth Preparation
- Tooth preparation is the mechanical or chemical treatment of dental disease or injury to hard tissue, restoring a tooth to its original form. It enables the tooth to hold restorative materials without causing mechanical or biological failure. The goal is now to minimize the amount of dentin involved in the preparation process.
Factors Influencing Tooth Preparation
-
The caries rate is being reduced by:
- Fluorides
- Nutritional counseling
- Oral hygiene programs
-
Cavity preparation principles (Black and Tylman) are evolving to accommodate new aesthetic and chemical techniques (e.g., acid etching and esthetic bonding)
Objectives of Tooth Preparation
-
Preserve tooth structure, reducing tooth reduction to a minimum.
-
Provide retention for the restoration.
-
Maintain an acceptable finish line to ensure resistance.
-
Perform minimal axial tooth reduction to encourage favorable tissue response.
-
Diagnosis and proper tooth preparation are critical for successful fixed prosthetics.
Principles Guiding Tooth Preparation
- Mechanical: Retention & resistance form
- Biological: Conservation of tooth structure, supragingival margins and harmonious occlusion.
- Aesthetic: Minimum metal display in restorations, porcelain thickness and subgingival margins.
