Ceramage
Ceramage
Ceramage a zirconium silicate integrated indirect restorative for both anterior and posterior regions.
A PFS (Progressive Fine Structure) filling of more than 73% plus an organic polymer matrix delivers superior flexural strength, elasticity and unsurpassed polishability.
Ceramage provides an extraordinary combination of durability and strength. Harder than other lightcured materials, it is extremely resilient and more elastic than conventional ceramics. Ceramage is an excellent solution for durable posterior restorations.
Main Features
- Flexural and compressive strength beyond 140 MPa
- Excellent abrasion resistance of opposing dentition
- Transmission and diffusion of light with a refractive index similar to natural teeth
- Superior color stability over 5 years
- Perfect viscosity and modeling properties
- PFS provides superb polishability and is effortlessly achieved
- Microstructure resists plaque accumulation
The natural light transmission and fluorescence of the CERAMAGE pastes allow restorations to exhibit a vivid brilliant appearance in the patient’s mouth – which exceed patient expectations. CERAMAGE virtually replicates the appearance and light diffusing properties of dentin and enamel.
The CERAMAGE PFS filler makes it possible to immediately match the light transmission properties
of surrounding teeth without firing. A complete selection of translucent effect color modifiers provide the freedom to solve inter-oral challenges easier than with porcelain. The build-up of metal-free inlays and onlays are simple and fast to fabricate. The structure and composition of CERAMAGE allows controlled application and modeling, even on small anatomical details.
Rationale for Indirect Composites
Not long after composite resins were first recommended as a posterior restorative system, the Europeans suggested using them as an indirect system. Two reasons were given. First of all it was recognized that as compared to the conventional amalgam restoration, the Class II composite was considerably more difficult to accomplish. Problems commonly encountered included less than ideal marginal adaptation, general anatomic form and loose and open proximal contacts and secondary caries. Secondly, limited laboratory studies suggested that subjecting the light-cured restoration to a subsequent heat treatment actually increased the wear resistance appreciably.
Unfortunately most of the inital systems were failures. Either the restoration fracured under stress, discolored considerably or simply did not show any enhancement in wear resistance. Now however, with the elimination of oxygen by curing in an inert atmosphere, the resultant restorations not only are considerably more esthetic than the direct composite resin counterpart, but the wear resistance is far superior to any other format. In fact, the resistance to wear over a ten-year period has been shown to approximately only one micron per year more than enamel.
These excellent findings now justify the use of laboratory processed composite resin on the occlusal table as a potential substitute for porcelain when the clinical condition arises. One of the most practical uses of this indirect resin is the coronal restoration of implants. In the case of the polymer, the energy of mastication is critically abosrbed by the restoration rather than transmitting this energy into the implant and into the surrounding periosseous alveolar structure. By comparison, the ceramic restoration absorbs very little of this energy and disperses it accordingly. Many clinicans have realized this relationship betwen material and energy transfer and are now using such materials as belleGlass NP to restore the coronal component of their dental implant.
Literature Review for Ceramage
According to S. Xue, the anatomic shape integrity, marginal discoloration, plaque index, gingival index and color match of Ceramage inlays were better than those of 3M Filtek™ P60 composite fillings(P<0.05), but marginal adaptation, secondary caries, fractures of the restoration and pulp sensitivity between Ceramage inlays and 3M Filtek™ P60 composite fillings were not different (P>0.05) which makes it appropriate for extensive cavities in the molar area.
Also, the use of ceramage in implant dentistry has also been extensively reviewed. According to Pei, Z, There was no significant difference in edge fitness,after 12 months abrasion between ceramage and PFM crowns,there was significant difference in shape and color between ceramage and PFM crowns. This means that in implant front teeth restoration, ceramage crown is better than PFM crown.
Technical Overview
CERAMAGE’s unique composition and uniform structure give it similar characteristics to
the finest ceramic materials, as well as, wide applications for both metal and metal-free
anterior and posterior restorations.
