Bioactive restorative materials are relatively new in dentistry. They are restoratives that are moisture friendly, transport water, and stimulate apatite formation at the material-tooth interface. In addition, these resins react to pH changes in the mouth by releasing and up-taking calcium, phosphate and fluoride ions, thus helping to maintain the chemical integrity of tooth structure. The first generation of this class of composites can be placed with or without a bonding agent and is delivered via a dual-barrel, automix syringe.
A total of 194 anterior and posterior Activa BioActive-Restorative restorations were originally placed and 158 of these restorations were recalled at two years. 76% of the restorations were placed with the use of bonding agent after etching, and 24% were placed without bonding agent after etching. 27% of restorations were on 1 surface, 49% on 2 surfaces, 22% on 3 surfaces and 2% on 4 surfaces.
Results at 2 Years
Lack of Postoperative Sensitivity: After initial placement, only a few patients reported some sensitivity, which subsided over time. At the 2-year recall, no patients reported any postoperative sensitivity.
Esthetics: The esthetics of the restorations was excellent. 96% of the recalled 158 restorations received a rating of 5, while 3 received a rating of 4, and 3 a rating of 3. Lower ratings usually were the result of slight staining and discoloration. None of these restorations needed replacement.
Resistance to Marginal Discoloration: Resistance to marginal discoloration was also excellent. Only 4 out of the 158 restorations received a rating of less than 5. 2 had a rating of 4 and 2 others had a rating of 3.
Wear Resistance: 99% of the restorations exhibited no signs of wear. Only 2 of the recalled restorations exhibited slight wear.
Retention: Retention was excellent. One restoration out of the 158 partially debonded and was replaced.
Activa BioActive-Restorative performed extremely well at the 2-year recall. Each evaluated category received a 96% or better rating. Overall Activa BioActive-Restorative received a clinical performance rating of 98% at the two-year recall.
- “I have used Activa BioActive-Restorative as a core in teeth with deep decay - the uptake of Ca, P and Fl could have a positive effect in these cases.”
- ”I like using Activa BioActive-Restorative in pediatric patients - it bonded well without a bonding agent.”
- ”The esthetics were excellent at 2 years.”
