Excellent Toughness
Fixed to the maxillary bilateral posterior teeth via bands or full crowns, the appliance cannot be removed by the patient, ensuring continuous and stable expansion force with high compliance.
Natural Aesthetics
It resists chipping and breaking ā a great choice if you grind your teeth at night or have a heavy bite.
Gentle on Opposing Teeth
Repairability
In case of chipping or unsatisfactory morphology intraorally or in the lab, composite resin can be directly added for repair without the need to remake the restoration.

What is the difference between a Ceromer crown and a composite resin crown?
They are essentially the same. Ceromer is a technologically upgraded highāstrength composite resin with optimized filler ratio and resin matrix, offering improved strength, wear resistance, and more stable aesthetics. It is an upgraded version of the composite resin crown.
What are the advantages and disadvantages of a Ceromer crown compared to a zirconia allāceramic crown?
Ceromer crowns offer better toughness, less wear on opposing teeth, repairability, and lower cost. However, the flexural strength (approximately 180 MPa) is significantly lower than that of zirconia (approximately 1200 MPa), making it unsuitable for posterior longāspan bridges or highāload cases.
How long does a Ceromer crown last?
Under good occlusal conditions and proper cementation, Ceromer crowns in the anterior region typically last 5ā8 years. In the posterior region, the service life is relatively shorter, approximately 3ā5 years.
Does the Ceromer crown discolor easily?
Highāquality Ceromer materials have a dense surface with good stain resistance. However, prolonged exposure to dark beverages such as coffee, tea, and red wine may still cause slight staining. Regular polishing and cleaning can restore the original gloss.
Is the Ceromer crown suitable for posterior restorations?
Yes, for posterior single crowns and inlays/onlays, particularly in cases with moderate aesthetic requirements and functional occlusal loads. It is not recommended for posterior longāspan bridges or heavyāload occlusal cases.
