What is Bioactivity? What are the current restorative results? What can we expect from Bioactive restorations? What are the patient and economic benefits? Can we participate in this environment and complement nature? The Oral Environment is Dynamic

The average service length for tooth-colored restorations is
cost about five billion dollars each year in the U.S. alone. If new more durable bonding systems can be developed, they will save patients and governments a great deal of money.

70% of all restorations in dentistry are replacements for failed restorations (Murray) 2006 data indicates 5 yr replacement 50% higher with composite restorations vs. amalgam (DeRouen) 9-year clinical data shows 50% of class II composite failures are due to gingival margin caries. (Nordbo)

BioACTIVE Restorative Materials release Calcium and Phosphate minerals to the demineralized tooth, replacing the minerals lost during low pH cycles or from caries. These minerals form a seal and a bond between the material and the tooth structure.
10
After demineralization
the minerals equilibrate and stabilize. As apatite forms, it can occlude the tubules helping to desensitize There is an absence of a hybrid layer, and there is a chemical and micro-mechanical bond.

Micro-leakage leads to marginal staining, demineralization, and caries Bioactivity and Apatite formation seal the margins and help prevent micro-leakage, caries and failure

“Bioactive materials together with biomimetic remineralization strategies represent an innovative and sound approach to remineralize dentine at the resin dentin interface up to its
have the potential to permanently protect the hybrid layer, and although more long-term studies are required, they will be a major influence on the future of restorative dentistry. Salvatore Sauro, Professor & Dr. of Biomaterials
“Lack of sensitivity, no chipping, excellent wear and esthetics was reported by patients and dentists at one year recall. ” (Dental Advisor, 2017) “ACTIVA’ s bioactive properties provided a seal at the margin and protected the restoration from microleakge and secondary caries. As a result the life of the tooth is extended and the patient is extremely happy!” (Dr. Bob Lowe)
