“On radiographs margins were defined and clearly visible.”
“Finishes nicely; polishes to a high luster.”
“A little sticky to instruments, especially the syringe material.”
“Color code syringes and unit-dose capsules by shade.”
Description
NanoEZis a universal composite filled with zirconia-silica nanoparticles. It is indicated as a direct restorative for all cavity classes in anterior and posterior teeth. The zirconia fillers are 80 nm in size and are harder than traditional barium glass fillers. NanoEZ has a high radiopacity and is reported to provide long-term fluoride release. It can be used with any bonding agent system and light cures in 20 seconds. NanoEZ is available in 13 shades, including seven Vita shades plus A5, three opaque shades, Opalescent A2 and Bleach White. NanoEZ is available in 4 g syringes and 0.2 g unit-dose capsules. NanoEZ intro kit was evaluated by 35 consultants in over 1400 uses. This universal composite received a 96% clinical rating.
Unique Attributes
NanoEZcomposite is filled 73% (by weight) with spherical particles that enhance its handling and physical characteristics. The medium viscosity of the material is soft enough to adapt to the preparation yet firm enough to sculpt. Most restorations could be completed with a single shade and blended well with the tooth, although cured shades were a little darker than the shade guide. Restorations finished nicely and polished to a high shine. Thirty-four percent of consultants rated NanoEZ better than other universal composites they were using and 46% rated it equivalent. Sixty percent would switch to NanoEZand 86% would recommend it to a colleague.
Clinical Tips from Evaluators
Wet your instruments to prevent sticking.
Check shade by curing some of the material before placing, particularly in esthetic areas.
Use at room temperature or a little cooler.
Use newer, sharper finishing burs to speed up the process.
Indications
Direct restorations in cavity Classes I to V
Composite inlays & onlays
Reconstruction of damaged teeth
Diastema closure & correction of the tooth’s shape & shade
RelyX Universal Resin Cement is a dual-cured universal cement with an innovative syringe design
It can be used in either the adhesive or self-adhesive mode for cementation.
Kit contains Scotchbond Universal Plus Adhesive for adhesive cementation
Available in shades A1, WO, A3O, and TR, which coordinate with the 3M™ RelyX™ Try-In Pastes
Innovative syringe and tip design to minimize waste
Excellent bond strength performance in DENTAL ADVISOR Biomaterials Lab testing
Clinical Evaluation Protocol
During a 24-month period, 636 restorations were cemented with RelyX Universal Resin Cement, in both adhesive- and self-adhesive mode. 452 restorations were one- to two- years old and availble for recall. For restorations requiring a bonding agent, Scotchbond Universal Adhesive Plus was used. The restorations included mostly crowns (anterior and posterior) and veneers, followed by implant crowns, bridges, and a few fiber posts (Figure 1). The vast majority were silica-based ceramic (lithium disilicate) and zirconia restorations (Figure 2).
Clinical Observations
Retention: Retention was excellent (Figure 4). All restorations remained intact, with no debonds occcuring over the two-year period.
Color Stability: Color stability rated excellent as well (Figure 4). Initial shades remained stable and restorations looked very natural. No shade shift or greying of restorations over time were reported.
Resistance to Marginal Staining: Resistance to marginal staining rated excellent (Figure 4). All restorations were observed to have smooth margins with no visible stain, indicating no marginal leakage at the tooth/restorative interface.
Evaluators’ Comments
“The new syringe and tip are a wonderful combination! The tip design significantly reduces waste; syringe is small and comfortable in hand, and a window shows amount of material left in syringe.
“This dispensing system is designed perfectly. It dispenses quickly, without bubbles and is extremely efficient.”
“Easy to use, easy to tack cure, easy to remove excess, and multiple modes available-all excellent!”
“It’s genius to combine two of my favorite cements, RelyX Unicem and RelyX Ultimate. Now I have one kit that does everything!”
Summary
A total of 636 restorations were placed over the past two years, using RelyX Universal Resin Cement and Scotchbond Universal Plus Adhesive as the bonding system for adhesive cases. 452 restorations were one- to two-years old and available for recall. All restorations received excellent ratings for retention, color stability and resistance to marginal staining. None of the restorations debonded over the two-year period. RelyX Universal Resin Cement received a 100% clinical perfomance rating at two years.
“The final restoration was very accurate and looked exactly like the mockup.”
“Having that initial shape is wonderful. It looks like it would be hard to trim after you open the doors, but it trims very quickly.”
“3M Filtek Matrix reduced my chairside time into less than half and gave amazing veneer like results in a very conservative way. “
“The final contours and esthetics of the composite veneers was great. My patient and I were both very pleased with the result.”
“I was pleasantly surprised at how there was not much excess composite interproximally.”
“This could be extremely helpful to clinicians who do not feel comfortable freehanding composite veneers.”
“The actual matrix was brittle and difficult to remove.”
“The lingual piece of the matrix was challenging to place.”
Description
3M Filtek Matrixis a unique customized anterior matrix system that is designed for predictability, efficiency and conservative dentistry. The digitally produced matrix fits your patient and allows for direct placement, creating easy to place anterior composite restorations.
Unique Attributes
Additive manufacturing allows for minimally invasive dentistry as opposed to ceramic restorations.
Large windows in the matrix allow for the use of universal composites and help the user view the fill level.
Doors on the matrix compress the composite and shape the facial contour. The doors also have engineered vents that allow for easy removal of excess.
Precise gingival trim allows the user to remove flash prior to curing.
Clinical Tips
Place and cure 3M Filtek Supreme Flowable Restorative at the gingival margin to help minimize the potential for voids.
Be sure to watch the instruction video – the process is extremely easy.
Avoid excessively overfilling the matrix as it may lead to more difficult removal after light curing.
Great for large case composite veneers and ideal if freehand veneers are new to you.
Use digital impressions to avoid the need to ship impressions and eliminate the time required for digitization.
Try a few cases; I suspect the process gets easier and easier.
