There are different types of filling materials for dental restorations. Glass ionomers,
such as Fuji 9, bond directly to the tooth surface, and do not contain methyl
methacrylate(plastic).

Dental composite resins however, are composed generally of 50% methyl methacrylate(plastic).
Composite resins do require a bonding agent, which is generally, a petrochemical based aldehyde. Aldehydes are  a highly toxic and non-bio-resonant family of chemicals, especially when in the liquid form, as it’s placed in the mouth before hardening.

Due to glass ionomer cements not containing plastic, and not requiring bonding agents,
they are quite bio-resonant, and generally do not create a stress response.

But glass ionomers are not as strong as composite resins, and are more recommended for
non biting tooth surfaces, such as the sides of teeth.

If a biting tooth surface needs restoration, what dental material can be used that will
be bio-resonant, or more so than conventional plastic fillings? Are any such products on the market?

Composite resin(white) dental fillings are considered to be the safe, healthy substitute for silver mercury fillings.

Some dental practices promoted as holistic, offer bio-compatibility testing with different brands of composite resins, using biofeedback. All composite resins however, in 20101, except one, are made of approximately 50% “filler” and 50% methyl methacrylate(plastic).

The “filler” in composite resins is usually silica, which is a very bio-compatible mineral. The other material that makes up approximately, 50% of dental composites, is plastic. Plastics are not bio-compatible, regardless of whether or not one tests somewhat better than another when using
biofeedback.

Composite resin dental filling materials, either contain Bisphenol A, as an ingredient, or there is possible Bisphenol A residue in composite resins, as a result of the dental material manufacturing process.

Bisphenol A is a harmful chemical compound, implicated in breast cancer, and known to be a hormone disrupter, mimicking oestrogen. Bisphenol A is  widely used in making hard, clear plastic, and is found in food and drink containers.

Call to ban 'breast cancer' chemical found in babies bottles

The following excerpt is from a web article: Gender
bending chemical Bisphenol a will be banned from
baby bottles in EU.

'Chief executive Belinda Phipps, of the UK National Childbirth Trust, told the BBC: 'When you put liquids into a bottle - particularly hot liquids or liquids containing fatty liquids - it leaches out of the plastic. And particularly as the bottle gets older and it gets more scratched, more and more leaches out and into the liquid.'
Ms Phipps pointed out that when a baby drinks from a bottle which contains BPA, the leached chemical is consumed by the baby and absorbed into its fat.
'It's a chemical that mimics estrogens, but not in a good way,' she said.
'It interferes with estrogens getting into the receptors, and it can have some very unpleasant effects - and animal studies have shown significant effects."

A  Kaiser Permanente study  on effects of exposure to BPA, appearing in the journal of Fertility and Sterility, conducted over five years by Dr. Li and associates, in China.

Funded by the U.S. National Institute of Occupational Safety and Health, this new study adds to
emerging human evidence questioning the safety of BPA, a chemical created in the production
of cans used for food and beverages, and in dental sealants.

The researchers explained that BPA is believed by some to be a highly  suspect human endocrine disrupter, likely affecting both male and female  reproductive systems.

"The finding of the adverse BPA effect on semen quality illustrates two points: first, exposure to BPA now has been linked to changes in semen quality, an objective physiological measure," Dr Li said.
"Second, this association shows BPA potential potency: it could lead to pathological changes of the male reproductive system in addition to the changes of sexual function.
“When you see this kind of association with semen you have to wonder what else BPA has an effect on,” said Dr Li.
As a precautionary principle, he said, “Everybody should avoid BPA as much as you can.”

A SAFER ALTERNATIVE TO CONVENTIONAL COMPOSITE RESINS

Following Dr. Li’s advice of “avoiding BPA as much as you can”, and the understanding that
it is or can be present in dental composite resins, wouldn’t every dentist and every person
looking for optimal wellbeing choose, or at least offer to people with a history of
chemical and petrochemical sensitivity,  a dental material that had minimal plastic component?

There is only one dental restorative material as far as this writer is aware, that does have very significantly less(50%less) plastic, and therefore BPA. It is manufactured by Voco In Germany, and the product name Is Grandio.

“My experience with Grandio Flow has been nothing but positive. I find it simpler to use than the other flowable composites I have employed in the past, without having an adverse effect on the quality of the clinical performance. Its ease of handling will make your clinical procedures more efficient, both from a time and cost perspective, while improving clinical outcomes.”

Grandio is also harder and more abrasion resistant than most other composite resins.

From Voco’s website. http://www.voco.com/en/news/press/Grandio_Flow_____Now_in_new_NDT___syringe/index.html:
 “ Grandio Flow is a flowable, nano-hybrid composite for the treatment of minimally invasive cavities, Class III to V cavities, extended fissure sealing as well as restorative repairs and veneer repairs. Moreover, it can be used to lute translucent dental prosthetics, such as full ceramic crowns and veneers. Grandio Flow can be used with all commercially available bonding materials.
Grandio Flow also offers its proven attributes in the new NDT® syringe. Grandio Flow is a persuasive material with ideal flowability and concomitantly high filler content of 80.2 w/w %. With a resin portion that is up to 50% less than traditional flow materials and even lower than some pasty hybrid-composites.  “

NON ALDEHYDE(PETROCHEMICAL) BASED BONDING AGENTS

There are some bonding agents which can be used with Grandio which do not contain
Petrochemical aldehyde. One of these bonding agents is G-bond.

The combination of Grandio with G-bond, would seem to be
the most bio-compatible choice for biting tooth surface dental restorations.
