How Does it Work?

SonicFill’s composite incorporates a highly-filled proprietary resin with special modifiers that react to sonic energy. As sonic energy is applied through the handpiece, the modifier causes the viscosity to drop (up to 84%), increasing the flowability of the composite, enabling quick placement and precise adaptation to the cavity walls. When the sonic energy is stopped, the composite returns to a more viscous, non-slumping state that is perfect for carving and contouring.


Confident Execution

The dramatic reaction to the sonic energy applied through the exclusive KaVo handpiece reduces the viscosity of the Kerr nanohybrid composite up to 84%.

This allows great adaptation, for reliable and predictable restorations.


Proven Performances

The special rheological modifiers allow the bulk fill composite to adapt its viscosity:

  • Sonic energy applied: viscosity drops for a quick and precise placement.
  • Sonic energy interrupted: viscous non-slumping state for great carving.


Shorter Procedures

SonicFill 2 uses refractive index matching and a more efficient curing mechanism to allow polymerisation depths up to 5mm.

The optimal shrinkage stress properties also enable a higher concentration of initiators for a more effective curing process.


Leaner Inventory

SonicFill 2 does not require liner nor capping layer, eliminating the need to stock up on multiple materials for different applications.

Moreover, its unique features in terms of adaptation, low shrinkage and depth of cure make it ideal for all larger cavity restorations:

  • Class I
  • Class II
  • Class V
  • Core build-up
  • Post-endo treatments

Know Your SonicFill Handpiece

The SonicFill Handpiece is air-driven and connects to dental units using a MULTIflex compatible coupling. The recommended operating pressure range is from 36-50 psi. The dispensing rate is selected by turning the regulating ring at the base of the handpiece. The dispensing rate range 1 through 5 only affects the flow rate of the composite – it does not change the composite viscosity.

Cleaning and Maintenance

The SonicFill Handpiece requires basic maintenance that includes cleaning after each use and a lubrication spray once per week.

Automated cleaners, such as the QuattroCare™ can be used or it can be manually cleaned between uses. Automated cleaners from other manufacturers will work as well – see the Handpiece Directions for Use for more information.


Simplified Procedures

Why does it simplify the dental procedure?

  • SonicFill 2 fills cavities up to 5mm in depth in a single increment with a single material – and no liner or capping layer.
  • Assures good adaption to the cavity walls and excellent mechanical properties.
  • Transforms tedious and repetitive posterior dental restorations into easy and reliable Single-Fill™ placements.

How does it do this?

The highly-filled proprietary resin with rheological modifiers reacts to the sonic energy applied through the KaVo handpiece.



When the sonic energy is applied, the viscosity drops, enabling quick placement and precise adaptation to the cavity walls.




When the sonic energy is interrupted, the dental composite returns to a more viscous, non-slumping state, ideal for carving and contouring.

The industry is talking about SonicFill – the bulk fill dental composite system that uses sonic energy to make posterior restorations easier, faster and more profitable than you ever imagined. See what your peers have to say about this innovative solution.

NOTE: Some material on this page focuses on the original SonciFill™ but is also relevant for SonicFill™ 2.

Among bulk fills, SonicFill continues to be in a class by itself with a 5mm fill in less than 5 seconds, superior adaptation, fantastic handling, high strength and no additional liner or capping layers needed. SonicFill 2 now adds an easily obtained high polish, even lower wear, less ambient light sensitivity and, with less translucency, an even better blend. So it is easy to see why the SonicFill brand will remain the market leader in this category of composites.
Dr. Ron Jackson
Along with its low shrinkage stress and high depth of cure, SonicFill 2 enables successful bulk fill procedures with seamless simplicity and efficiency. This is what dentists deserve and expect.
Parag R. Kachalia
Finally, a practical, efficient technique for placing posterior composites in one, single, esthetic, bulk fill increment. SonicFill is a game changer.
Dr. Ron Jackson
Are you ready for the next step in the evolution of direct composite delivery? SonicFill will change the way composites are done forever! Simplicity and perfection in one step.
Dr. Robert Lowe
SonicFill makes composite restorations easy, effective and efficient by utilizing a new technology. Now clinicians can bulk fill preparations without a concern of shrinkage or marginal discrepancy.
Dr. Ara Nazarian
Sonicfill makes direct resin restorations fun again. Bottom-line. The new patented resin technology enables the practitioner to place a posterior direct resin more quickly, efficiently, and profitably than traditional techniques. All without sacrificing quality.
Dr. Chris Pescatore
Without a doubt, SonicFill is the best handling posterior composite I've ever used...the more I use it, the more I like it!
Dr. Gary M. Radz
Sonicfill's unique delivery system and material handling qualities will assure the clinician that the restoration will be filled in the most expedient manner technology can deliver. Sonicfill is especially valuable in class II restorations, giving the dentist confidence that the entire restoration will be sealed for predictable long-term results
Dr. Steven Poss
SonicFill gives me the ability to place direct restorations predictably and efficiently. The end result is a quality restoration, a productive dentist, and a satisfied patient
Dr. Daniel Rovirosa
When I die I want to be buried with a picture of my wife, a picture of my daughter, and my SonicFill
Dr. John Sherwood, Palmerton, PA
When you use SonicFill you feel more confident in what you’re doing.
Dr. Greg Gillespie, Vancouver, WA
SonicFill is a great application for cores under crowns and bridge after root canal treatment. Often the access opening is small making it difficult to fill. We have found SonicFill to be "user friendly" in treating children
Dr. David Slekovich, Livonia, MI
I love SonicFill, less voids, much easier to place the composite, faster. Also, I love using XTR bonding knowing that I am getting a 40 mpa bond to enamel and less sensitivity with dentin. Thanks for the innovations.
Dr. James W. W. McCreight, Steamboat Springs, CO LVI Clinical Instructor
I have used the system for one year following last year's Core3. SonicFill is easy to use and makes direct restorations fast, predictable, aesthetic and fun. It's a definite move up from the previous method I used when placing composites. It is also reassuring to know that Ron Jackson approves of the product considering his level of understanding of the chemistry of composites and the fact that he uses SonicFill on his own patients. SonicFill has definitely improved my dentistry and I'm grateful for that. If you are committed to doing high quality dentistry this system is a must.
Dr. Mark Tompkins, Cornelius, NC, LVI Clinical Instructor
I have been using SonicFill for about 2 years. I can't say enough about this product. It is a real game changer. My ability to place posterior composite has never been better or easier. Patients are amazed at how quickly we are able to complete their treatment. The results are simply incredible. No more layering. Anatomy can be established quickly and there is little or no polishing needed. In addition the material just disappears after curing. I no longer dread that quadrant of posterior composites at the end of the day.
Dr. Larry Evola, Lancaster, NY, LVI Clinical Instructor
I have practiced dentistry for 24 years and have hated posterior composite resin restorations for all 24 years. Two recent Kerr products have revolutionized my feelings. One is OptiBond XTR that has eliminated many postoperative sensitivity issues. The second is SonicFill. Because the material is so superior in handling and adaptability without sticking to the instruments, the restorations pack easier and better. For the first time in 24 years, I actually do not mind doing posterior resins!
Dr. Michael F Cronin, Leominster MA
I have a graduate working with me and I'm jealous of how he gets to come into dentistry in the SonicFill era. All those years of having to do composites the slow, technically difficult way nearly made me give up altogether. Now I'm not only doing them faster, I'm much more confident in the quality, and it's just downright fun!
Dr. Dan Andrews, Altona North, VIC AU
SonicFill is great stuff. It has great handling properties. I like the fact that you don't have near the problem of incorporating voids between layers. It seems to stay where you put it without a pullback.
Dr. Stan Hirst, Minot, ND
Using the SonicFill product has given more & more confidence that I can place restorations with no void or gaps in the matrix
Dr. Bethany Jensen, Minot, ND
I have been using SonicFill for about 6 months along with the OptiBond XTR and have truly enjoyed placing restorations that are well sealed and of superior strength and integrity.In deeper areas, I still use a flowable under the SonicFill just out of habit!!
Dr. John Hill, Ottawa, ON
Used a SonicFill Demo on pediatric patients for a month and loved the product. Makes restoring teeth so much more efficient, and the material looks great. Nothing but positive things to say about this device.
Dr. Wesley Barton, Boston, MA
I have been in practice for 35 years. One year ago, I purchased SonicFill and fell in LOVE with it immediately. It is so easy and works fantastic. Great results!
Dr. Mel Markham, Westminster, CA
I love the simplicity of the delivery system. Works well and provides a Very dense fill with NO VOIDS. Love the product!
Dr. Douglas Bohne, Mission Viejo, CA
In pediatric patients, where working time can be limited, SonicFill is a must have. Every pediatric dentist should add SonicFill to their arsenal.
Dr. John De Lorme, Mission Viejo, CA
I haven't had one sensitive tooth since using OptiBond XTR and SonicFill (SF), and I have done over 500 SF restorations. It's given me a renewed interest in composite restorations. The greatest Time Saver and Money Maker in history. We did in one day around $6K in less than 3 hours…
Dr. R.J. Smith, Covina, CA
Works great! It's idiot proof!
Dr. Ronald Fujioka, Covina, CA
The sonic unit makes the composite flow well enough to completely fill the whole interproximal boxes, never leaving any space, bubble or voids, no matter how deep the box is. The material is beautiful and easy to handle and sculpt. It is fast to fill and cure even large restorations. When I am finished, the margins are all closed and the tooth looks like it was before it had any caries! The filling is invisible! I have been waiting for this material for at least 12 years. I am so happy!
Dr. Keyla Springe, Paso Robles, CA
Contacts are MUCH better. Easy to clean-up and I love the radiopacity and, it handles beautifully…packs up against the cavosurfaces nicely. It's easier to work with and carves up nicely…and, no voids
Dr. Dan Sizemore, San Dimas, CA
SonicFill has drastically improved the quality of my posterior resins. I love the way this material flows evenly, eliminating voids and bubbles. The speed in which I can place them is also a plus. Consistency I can depend on, quality I love!
Dr. Nina Foley, Franklin, TN
SonicFill is a real "game changer" in placing posterior composites. I can't say enough about the benefits of the ease of placement. The time savings alone will pay for the handpiece after 3 restorations. It also helps lessen the physical stress on the operator, the assistant, and most importantly on the patient. The decision to use it is really a no brainer as there is nothing that can compete with the advantages. If there is anything better out on the market I would like to know about it
Dr. Max Ebrahimian, Scotts Valley, CA
SonicFill combines superior handling quality with excellent esthetics, all in the most efficient delivery system on the market. If you're placing posterior composites, you cannot afford to go without this system!
Dr. Ariana Ebrahimian, Scotts Valley, CA
SonicFill allows me to place very deep posterior resins with confidence in one step. My patients are very happy with the result and with the fact that it takes less time. I was so happy with the one I bought that I purchased two more
Dr. R. Shawn Essey, Pittsburgh, PA
I frequently found composite posterior restorations tedious. SonicFill has rejuvenated my experience. I find placement to be easy, quick, and a pleasure to suggest to my patients. The headaches are gone
Dr. Robert J. Varone, Warwick, RI
SonicFill has simplified my life. My posterior composites take less time, look nicer, and have less sensitivity. The final restoration has an incredible chameleon effect. The final restoration looks very similar to a porcelain restoration at a fraction of the cost to my patients. Thanks for making posterior composites fun again
Dr. Jonathan Nelson, Windsor, CO
Absolutely LOVE the SonicFill system. It is easy to place and gives you the confidence that you are eliminating any voids in a composite. Having one was not enough, I needed one for each restorative operatory. It also makes core buildups a breeze and very solid when prepping for a crown. Thanks
Dr. Tamara Berg, Yukon, OK
SonicFill has changed my practice for the better! I used to dread appointments with back to back Class II composites. Now I look forward to completing treatment efficiently and successfully with the SonicFill. It is also a huge help with large Build-ups. I use the SonicFill any time I can-- it makes dentistry more fun and more predictable for me
Dr. Stefanie Shore, Carmichael, CA
I began using SonicFill in April of 2012. I only place composites in my office and restore each myself. With only so much procedure time in a day anything that can increase the speed of a procedure is an immediate boost to the practice. After analyzing procedure times I have found it saves me about 5 minutes per tooth. That adds up quickly over time allowing me to see 2-3 extra patients a week. I have also been very pleased with the quality of the restorations and handling of the material. It has been especially useful for pediatric patients due to the decreased time to fill allowing for better results due to decreased time needed for isolation.
Dr. Jonathan Woodyard, Paducah, KY
SonicFill makes it easier to fill posterior composites void free and it's quick and easy.
Dr. John Day, Lansing, MI
Excellent system. Improved time efficiency and improved the quality of posterior composites polishing and contact.
Dr. Ron Goodman, Warren, MI
Makes posterior composites fun. Proximal contacts seem easier to maintain and patients seem to have way less sensitivity.
Dr. Gary Krebill, Kalamazoo, MI
The SonicFill has made filling all composite restorations easy. What a great product. Everyone should own one!
Dr. Carl Papa, Roseville, MI
I love the way SonicFill feels, flows and fills. It packs well with no bubbles and fills quickly.
Dr. Charles Zammit, Southgate, MI
SonicFill has reduced the amount of time I need to schedule for my restorative appointments. Easy to use, great contacts, excellent esthetics. A true game changer!
Dr. Mark J. Birnbach, Boulder, CO
I started using SonicFill just weeks after it became available in Canada. Using SonicFill in combination with the incredible knowledge that Dr. Jackson shared about adhesion, I looked at my assistant a few weeks later and said, 'We are doing the best dentistry we've ever done.' I have many colleagues who are sharing the same sentiments and it's awesome!
Dr. Drew Markham, Huntsville, Ont
have been using SonicFill in the office for over a year now. It has quickly become one of those things I couldn't practice without. The convenience is extraordinary, but the best part is how easily it flows into the tooth and into the preparation box forms. There are no voids, no unfilled areas, no gaps. The material is also very easy to handle and has great esthetics. It has allowed me to place composites much faster, much easier and with a much better final result
Dr. Kent Johnson, Park City, UT


Can I use my existing SonicFill Handpiece for SonicFill™ 2?


At what air pressure should the dental unit be set for SonicFill Handpiece?

The ideal air pressure is between 30-50 psi.

Can I use SonicFill Handpiece on any air line within my operatory?

Yes, SonicFill can be used on any air line that has the proper pressure and is equipped with a MULTIflex coupler.

Will SonicFill Handpiece work with any MULTIflex coupler?

Yes, SonicFill Handpiece will work with any MULTIflex coupler.

Can I use an automated cleaning system such as QuattroCare™ with the SonicFill Handpiece?

Yes, SonicFill Handpiece can be cleaned with automated systems. Please observe the manufacturer's directions for use for the cleaning system, and review the handpiece directions for use regarding use of these systems.

If I don't have an automated cleaning system, what type of maintenance should be done on the SonicFill Handpiece?

Before disinfection, the handpiece should be cleaned using a brush under running water between uses. The SonicFill Handpiece Lubrication Spray should be used at least once weekly, after cleaning but before sterilization. Use of the QuattroCare system eliminates the need for the lubrication spray.

What products are recommended for manual disinfection of the SonicFill Handpiece?
