Product Details
A bioceramic luting cement for the permanent cementation of full coverage crowns and bridges made of high strength ceramics or metal.
- Integrates completely with tooth structure and creates a seamless interface between the tooth and cement.
- Maintains an alkaline environment to resist acid and bacterial decay; not sensitive to moisture.
- Self-adhesive; no tooth or crown preparation is required.
- Available in self-activated QuikCap capsules (no separate activator required) or in hand-mix powder/liquid delivery.

Clinical Evaluations
Ceramir Crown & Bridge was evaluated by 20 consultants in 314 uses. This product received a 92% clinical rating.
Description
Ceramir Crown & Bridge is a permanent, radiopaque, bioceramic luting cement supplied in capsules. It is indicated for conventional cementation of metal-, lithium disilicate-, alumina- and zirconia-based restorations. The capsules contain glass ionomer powder and bioceramic (calcium aluminate) powder plus water.
Mixing is done in a 4000-5000 rpm mixer. Dispensing requires use of either the Ceramir Applicator, Aplicap Applier (3M) or the AC Applicator (VOCO). Ceramir Crown & Bridge is self-setting with a working time of two minutes and a setting time of four to eight minutes. The cement is designed to be biocompatible and to resist acid and acid-producing bacteria. It requires no etching, priming, bonding,
or conditioning.
Clinical Observations
Packaging and Manufacturer’s Instructions: Within the box, each of the 20 capsules of Ceramir Crown & Bridge is individually packaged in a foil pouch. Instructions are clear and concise and are accompanied by a pictorial card for quick reference. Consultants rated packaging and instructions as good.
Ease of Activating, Mixing and Dispensing: After mixing, the nozzle of the capsule must be rotated 180° before extruding the cement. Failure to rotate the tip can result in cement coming out of the seams in the capsule. Assistants noted that a homogeneous mix of cement was achieved in all cases.
Viscosity of Mixed Cement: Consultants rated the viscosity as very good. The cement is smooth and creamy and coats the surface of the restoration well. Upon seating, little to no resistance was felt by the dentists placing the restorations.
Working and Setting Times/Removal of Excess Cement: Working time was rated as good. The two minutes working time is adequate even in cases of mixing more than one capsule. The cement reaches a rubbery stage after additional one to two minutes, when clean-up is recommended. Removal of excess cement at this stage is very easy. After cleanup, the restoration must be stabilized for an additional four minutes. Consultants would like the option of a faster setting time.
Esthetics of Mixed Cement: The cement is a bright white color, which facilitates visibility and clean-up at the margins. In cases of translucent zirconia restorations, shine-through of the opaque cement can occur.
Post-insertion Sensitivity: There were no reports of post-insertion sensitivity.
Summary
15% of consultants reported that Ceramir Crown & Bridge was better than their current crown and bridge cement and 60% reported that it was equivalent. 60% would switch to Ceramir Crown & Bridge and 85% would recommend it.
Consultants’ Comments
- “A capsule mixer and applicator are required for use.”
- “Perform clean-up in the rubbery phase, around three minutes after mixing.”
- “Do not use with lower-strength glass ceramics.”
- “Store at room temperature.”
