Virtuoso Universal (8 yr)
- “Color is stable.”
- “Restorations look amazingly good at this point.”
- “Nice radiopacity.”
Virtuoso Universal is a high-viscosity microhybrid composite intended for anterior and posterior use. It is supplied in unit-dose capsules in Vita shades A1, A2, A3, A3.5, B0, B1, B2, C1, and C2. This product received a 92% rating for clinical performance at eight years.
Clinical Evaluation Protocol
- Between the years 2000 and 2003, over 250 restorations were placed in 192 patients using Virtuoso Universal composite. Of these, 134 restorations in 77 patients were available for recall (Figure 1).
- A variety of anterior and posterior restorations were placed: 26 were single-surface (occlusal); 97 were two- or three-surface; and 11 were 4-surface restorations (Figure 2).
- An array of bonding agents was used including Tenure A & B.
- Restorations were evaluated on a scale of 1 to 5 (1 = poor, 2 = fair, 3 = good, 4 = very good, 5 = excellent).
Virtuoso Universal has exhibited excellent resistance to fracture and chipping during the evaluation period. Seventeen of the 134 restorations exhibited moderate chipping and four of these required replacement. Many of the chipped restorations only needed to be smoothed; two were repaired with flowable composite (Figure 3).
The esthetics has remained fairly consistent over the evaluation period. The pie chart (Figure 4) shows the percentage of restorations receiving excellent to fair ratings. More than half of the restorations received an excellent rating.
Lack of Marginal Discoloration
Fifty-nine percent of restorations were rated excellent for resistance to staining at the margin. Slight staining was observed in 32% of the teeth restored. The remaining 9% showed moderate staining. No restorations were replaced for this reason (Figure 5).
Seventy percent of the restoration recalled showed no visible signs of wear. Slight to moderate wear was noted in 30% of the restorations (Figure 6).
