All-Ceramic Zirconia

Zirconia core with e.max® ceramic layering. A combination of high strength and excellent aesthetics. Zirconia all-ceramic restorations (ZrO2) are digitally designed using CAD/CAM technology. The zirconia core with e.max® ceramic overlay offers a unique combination of aesthetics and durability, making it suitable for any crown or bridge application.

Indications:

• Suitable for anterior and posterior restorations
• Appropriate for extensive cases
• Suitable for discolored teeth, due to the opacity of the core

Contraindications:

• Patients who grind or clench their teeth

Monolithic Zirconia

Monolithic restorations are crowns/bridges made entirely from zirconia without any ceramic layering. They are a single-material restoration with full anatomy, strength, biocompatibility, and aesthetics.

Indications:

• For posterior restorations
• For bruxist patients and those with low vertical dimension

Contraindications:

• For anterior restorations
• For teeth with significant translucency

All-Ceramic Inlays and Onlays

Pressed E.max® inlays and onlays offer superior quality and aesthetics. This is an alternative proposal to resin, even for replacing existing amalgams. With the Press technique, IPS e.max® provides excellent aesthetics and functionality.

Indications:

• Patient’s demand for aesthetic results
• When large cavities need to be filled
• For individuals with effective oral hygiene

Contraindications:

• Presence of extensive caries

E.max® Veneers

All-ceramic lithium disilicate veneers (IPS E.max®) provide a perfect natural result. Lithium disilicate is an ideal material for constructing veneers. This innovative ceramic offers outstanding aesthetic results and exhibits 2.5 to 3 times greater strength compared to other glass-ceramic materials.

Indications:

• For teeth with fractures in the incisal third
• For teeth with gaps between them
• For slightly crowded teeth
• For teeth with shape or size anomalies

Contraindications:

• For patients who grind or clench their teeth
• For patients with habits (e.g., nail biting)

Metal-Ceramic

Traditional metal-ceramic restorations offer a combination of strength and aesthetics. Proven for over 50 years, traditional metal-ceramic restorations provide a blend of durability and aesthetic appeal.

Indications:

• For anterior and posterior restorations
• For combination with removable prosthetics
• For extensive restorations

Contraindications:

• Patient has an allergy to metals (CoCr)

Implant-Supported Restorations

Cemented Restorations
A cemented crown/bridge is a restoration made on an abutment secured with cement. Some advantages include good aesthetics, simplicity of technique, and complete passivity.

Screw-Retained Restorations
A screw-retained crown/bridge is designed with a hole on the lingual or occlusal surface. This hole allows the restoration to connect directly to the implant via a screw. The clinician can remove the restoration for cleaning, repair, or tightening the screw. A screw-retained restoration makes all these processes achievable.
