Biocompatible and Bioactive Materials

[vc_row][vc_column][vc_column_text]At The Natural Smile we have a lot of experience of using Biocompatible and Bioactive materials in many different situations.

Biocompatible means that the substance is not harmful to human tissue.

Bioactive  means that it has an effect on human tissue. 

We have been using them for a long time with great results.  These materials not only produce excellent aesthetics, but their biocompatibility ensures that they integrate with the body extremely well.  The bioactive properties of Biodentine can actually promote healing of damaged tissue –  potentially saving a tooth that might otherwise be lost.  A little more information on the different materials we use is included below.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]ADMIRA FUSION

Admira fusion is the material we use for fillings, it is biocomaptable and gives excellent aesthetic results, it is an ormocer meaning it is ceramic based making it both hard wearing  and resistant to colour changes.  Another huge benefit of it being ceramic based is that it is plastic,  BPA and GMA free, (no monomers, no Bisphonal A, no Glycidyl Methacrylate), unlike the majority of composite filling materials available today.  Please have a look at this leaflet produced by VOCO who make the material for more information.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]


  • Biodentine and BioRoot are biocompatible and bioactive and actively promote pulp (nerve) healing as well as remineralisation of dentine. (both contain bioactive tricalcium silicate material) Biodentine can be used therefore wherever dentine is damaged both in the crown and in the root and particularly where this damage is threatening to the health of the nerve.  BioRoot is used when sealing root canals ready for filling.
  • Biodentine forms natural ‘micro-mechanical attachments’ into the dentine giving an excellent seal, allowing only minimal tooth preparation and helping to eliminate sensitivity that can be experienced after conventional treatment.
  • The final restoration is highly comparable to human dentine showing similar mechanical properties and behaviour.
  • It is easily visible on x-rays for easy short and long term follow-up.

If a cavity in a tooth is very deep & close to the nerve, the nerve will likely be affected by the decay, and treatment to restore it, and may react becoming sensitive and painful and sometimes ultimately will die off requiring either a root filling or extraction of the tooth.

Because Biodentine promotes natural healing of the nerve by stimulating it to lay down a protective layer of dentine without irritating the nerve in any way, it increases the likelihood that the nerve will recover and survive in the longer term. (This has even been shown to be the case where the nerve has been significantly damaged). Biodentine will need to be covered with a permanent restoration, such as a white filling (see Admira Fusion above), either immediately or left as a “temporary” base for up to 6 months, and then permanently restored at the second visit. The latter usually only being done when the nerve is badly affected, to ensure that it has settled prior to permanent restoration.

Other Uses include:

–   Temporary fillings

–   In the root: root perforations, internal/external restorations, retrograde surgical filling.

–   Children

Because of Biodentine’s properties of helping to ‘heal the pulp’ and of bonding to dentine as well as being a gentle and more natural treatment we also feel that it’s a great treatment for repairing decayed ‘baby teeth’, leaving it as a semi-permanent restoration until the tooth is naturally lost. The limitations on its use in children however are the need to attain good moisture control and of leaving the filling to fully set in the mouth for about 10 minutes so it is not suitable for all patients and all cases.


The only disadvantages of these  materials are their cost and additional working time and so at the moment it is offered as an option with additional cost per treatment. However, this treatment is designed to try to reduce the chance of this tooth needing a root filling and of tooth loss & additional costs and treatments associated with this later on – Your dental estimate will include accurate costings if Biodentine or BioRoot treatment has been recommended for you.
