Which restoration approach minimizes tooth structure removal while still providing adequate support?

The approach that minimizes tooth structure removal while still providing adequate support is intracoronal restoration. This technique involves placing the restoration inside the tooth structure, which allows for conservative preparation, conserving more of the natural tooth structure compared to other methods.

Intracoronal restorations, such as bonded composite resins or inlays, require a smaller amount of tooth preparation. They are designed to fit precisely within the confines of the existing tooth structure, which not only maintains the integrity of the tooth but also provides a strong support system through adhesive bonding techniques. This is particularly important for retaining the strength of the tooth while ensuring it can withstand normal functional forces.

In contrast, other restoration options, such as fiber-reinforced restorations or cast crowns, typically require more extensive tooth preparation. Fiber-reinforced options might still entail significant adaptation of the tooth structure to accommodate the reinforcement. Similarly, a cast crown necessitates the removal of a considerable volume of the tooth to allow for the thickness required for proper crown fabrication, which may compromise tooth vitality if excessive structure is removed. Amalgam inlays, while conservative compared to full crowns, still require more tooth reduction than intracoronal restorations to ensure adequate retention and support.

Thus, the focus of an intracoronal
