Summary

Metal-free restorative systems offer esthetic and minimally invasive options for fixed partial dentures (FPDs). Initial clinical findings show promise, though material limitations require careful consideration.

Area of Science:

Dental Materials Science
Restorative Dentistry

Background:

Metal-free restorative materials enable new preparation techniques linked to adhesive cementation.
Advancements have introduced various metal-free systems for fabricating short-span fixed partial dentures (FPDs).

Purpose of the Study:

To illustrate treatment procedures for two metal-free restorative systems.
To report initial clinical findings on metal-free inlay-retained FPDs.

Main Methods:

Examined 23 metal-free inlay-retained FPDs (11 ceramic, 12 fiber-reinforced composite) since 1997.
Focused on FPDs in patients with low caries activity, emphasizing minimal invasiveness.

Main Results:

One ceramic FPD required replacement due to fracture.

Long-term results are unavailable due to the recent market introduction of these materials.

Conclusions:

Metal-free restorations offer excellent esthetics and reduced invasiveness compared to full crown-retained FPDs.
Indications for these restorations are limited by the specific mechanical properties of the materials.
