All MTA-Type Products are Bioactive Bioceramics

Avalon Biomed Inc. has a mission to save teeth with MTA-type products. Uniquely qualified, our management team has 19 years experience inventing and manufacturing MTA, including three patents for MTA. Understanding the chemistry, products and clinicians’ needs, we developed premium MTA-type products with affordable pricing, to ensure the product’s use.

A note about Bioceramics from company president, Carolyn Primus, PhD, Materials Scientist:

 MTA Plus Root & Pulp Treatment Materials (NeoMTA Plus and Grey MTA Plus) from Avalon Biomed are bioactive bioceramics, as are all MTA-type products (mineral trioxide aggregate). By definition, a bioceramic is any ceramic used in vivo. Bioceramics are inert, but bioactive bioceramics induce the precipitation of hydroxyapatite in synthetic body fluids or in vivo.

MTA Chemical Composition

All MTA-type products are formulated with tri/dicalcium silicate and blended with various radiopaque powders. (Table 1). Products in the marketplace vary in their amounts of radiopaque powder, particle size distributions, and minor phases. It is these variations in composition that affect properties such as setting time and handling characteristics.

* Bismuth oxide, barium zirconate, zirconia, and/or tantalite

All MTA-type products are hydrophilic. They require water for setting and calcium hydroxide is a reaction product, embedded in the cement matrix, as shown in equation 1.

NeoMTA Plus is a stainproof, tricalcium silicate-based bioactive cement that can be used universally for vital pulp and other endodontic indications in primary and permanent teeth. NeoMTA Plus is a bioceramic cement that triggers the healing process. With NeoMTA Plus, general dentists, pediatric dentists, and endodontists now have a superior and reasonably priced bioceramic. Dentists praise the multi-use NeoMTA Plus because it mixes more smoothly, is easier to dispense and the unique gel enables more stable placement, washout resistance and faster clinical setting.

New, stain-free light color:

Ideal for pediatric dentistry—won’t discolor teeth
Liquids such as sodium hypochlorite won’t cause discoloration

Multiple indications:

Pulp-capping to base/liner
Pulpotomies to apexification
Sealer to perforation repair
Root-end filling to resorption


Inhibits bacterial growth* *Tested in vitro. Not a disinfectant

Grey MTA Plus is a bioceramic tricalcium silicate-based Dental Cement, which is slightly more radiopaque than (white) MTA. The light silvery color of MTA Plus is visible during placement. Grey MTA Plus is indicated for both Vital Pulp Therapy and Endodontic procedures. General dentists and endodontists praise the multi-use Grey MTA Plus because it mixes more smoothly and is easier to dispense. The unique gel enables more stable placement, washout resistance and faster clinical setting.

Multiple indications:

Pulp-capping to Base/Liner
Pulpotomies to Apexification
Sealer to Perforation Repair
Root-end Filling to Resorption

New, light grey color:

More radiopaque than the leading white MTAs
Visible for precise placement
Inhibits bacterial growth in vitro of Staphylococcus aureus, Escherichia coli, Enterococcus faecalis, Pseudomonas aeruginosa.

Better mixing, handling and placement:

Finer powder mixes more easily and smoothly
Dispense as little as 0.1 gm
Unique gel for stable placement
Washout resistant
No special equipment required

Smart, convenient packaging:

Protects fine powder in desiccant-lined bottle
Easy to dispense powder as needed
Dropper-tip gel bottle minimizes waste
